Introduction

Climate change is a worldwide phenomenon, which directly affects all nations. However, the effect is more explicit among countries closest to the poles, such as Canada. Such an occurrence negatively affects the nations economy, urban infrastructure, and politics due to ice caps melting. The economy and the financial sector are primarily influenced by the overall increase of risk factors associated with climate change, such as storms, avalanches, or droughts. The prevalence of highly fluctuating climate with high-end extremes can lead to urban shifts in the form of infrastructure destructions and uninhabitable zones. Canadas political arena will also be affected because such ramifications will build the basis to support climate change proponents. Lastly, the countrys ecosystems will be severely damaged due to biodiversity and habitat loss.

Main text

Canadas economy and infrastructure have experienced some form of hindrance due to climate change. Climatic systems in Canada changed both as a result of non-anthropogenic and anthropogenic influences, and external influences and natural internal processes. There is a presence of long-term climatic cycles, which in the allocated period took the pattern of periodic glaciations, and the present time falls on the interglacial. In addition to elevated sea levels, rising global temperatures will also lead to changes in the amount and precipitation distribution. As a result, natural disasters, such as floods, droughts, hurricanes, and others, became more frequent, crop yields decreased, and many species disappeared. Warming should, in all likelihood, increase the frequency and scale of such phenomena. In Canada, there is an increase in atmospheric CO2, and warming leads to serious changes in the taiga and tundra ecosystems of the Arctic and Subarctic. There was a change in productivity, a shift in species composition, a shift in the border between the forest and the tundra.

However, its negative effect will be more detrimental in the future. The climate is constantly changing under the influence of natural and human-made factors. Among the anthropogenic factors of climate change, the greenhouse effect is the most significant. Never in the past half, a million years has there been such a high concentration of GHGs in the atmosphere. The increase in carbon dioxide (CO2) in the atmosphere is the result of the release of carbon mainly by human intervention, such as industrial emissions, the burning of various fossil fuels, and a reduction in the forest area. It is important to note that the issue of climate change is a major global crisis. The Canadian economy, urbanization, and politics will directly experience the effects of climate change. A change in the processes of heat and moisture transfer may occur, which will lead to an increase in the number, intensity, and frequency of natural disasters. This will critically affect the countrys urbanization and infrastructure. Melting ice sheets of Antarctica and Greenland are leading to a rise in sea level, which will cause the collapse of coastal structures and coastal erosion, salinization of drinking water.

Subsequently, the Canadian economy will suffer severely due to a lack of basic resources and the dysfunctionality of offshore infrastructures. Productivity reduction is possible in most tropical and subtropical regions in the middle latitudes, which poses a threat to global food security. There are negative effects on human health, such as the effects of heat stress on the most vulnerable populations, the spread of disease vectors, and lowering the quality of water and food. The instability of ecosystems may begin to increase, which may cause irreversible losses in them. Politics will be affected due to the serious socio-political consequences of the region, such as climate refugees, imbalances in quality, cost of living, and equality.

Conclusion

In conclusion, it is important to note that Canada will be one of the first victims of global climate change. The nations economy will be primarily damaged by several factors, such as irregular droughts, sea-level increases, and abnormal wave patterns. The countrys financial sector will have to account for environmental risk factors, which will be a heavy burden on the economy. Canadas infrastructure and urbanization will be severely damaged by the shift and expansion of uninhabitable zones, which will lead to climate refugees. The latter will impact the nations socio-political state, where various regions will experience a major drop in quality of living.

Introduction

If the world does not address climate change, workforce shifts, apocalyptic issues, water shortage, and biodiversity decline will occur, and we will end up with collapsed civilization. According to Amanda Ruggeri (2017), major climatic changes will heavily impact the workforce, where organizations will become more concerned about global threats and need relevant workers. According to Alex Williams (2017), climate change will result in apocalyptic conditions, which require extra measures. Chris Young (2019) argues that extreme heat increases will lead to severe water shortages. Chelsea Harvey (2018) claims that climate change will have dire ramifications on biodiversity by facilitating species loss. Thus, many organizations might need climatologists to make future business decisions. People might have serious problems with getting shelter and food. In addition, water might become a highly scarce form of resource. Several species will most likely disappear due to sudden changes. It is important to analyze the most probable shifts in the workforce first.

Workforce

Many businesses and employees will be heavily affected by the changes in the climate due to newly emerging environmental threats and risk management factors. Ruggeri (2017) states: job postings in the renewable energy sector  made up of bioenergy, geothermal, hydroelectric, solar, and wind  accounted for a third (32.9%) of all energy-sector job postings in the first quarter of 2014. In 2017, that had risen to over half of all energy sector job postings or 51.5%. (para. 14). There is a growing need for professionals that understand the impact of climate change on the energy sector. More and more climate experts will be needed alongside engineers specialized in green energy. It affects all societies, especially the younger generation, who will have to take on these roles. There would be a gradual increase in vacancies in the energy sector. Future generations will be faced with high demand for climatologists and engineers for green energy. Ruggeri (2017) also writes: Coca-Cola, Ikea, and Walmart also have committed to 100% renewable energy (para. 23). This means that large corporations are becoming more aware of global changes in the environment, and therefore, they will initiate the shift from fossil fuel to green energy sources among corporate and business entities. It is important because many organizations will realize the magnitude of the threat of climate change. It affects all forms of organizations, including non-profit and for-profit ones. Currently, it would mean that many large companies will seek to reduce their dependency on the fossil fuel industry. Future generations will have to consider the importance of energy renewability when opening a business or stepping into an organization. These changes do not take into account the potential severity of global warming.

Apocalyptic Issues

One needs to be aware that drastic climatic changes can force everyone to become a survivalist. Williams (2017) states: In the event of a megadisaster that leaves parts of the city uninhabitable, survivors might require cheap, stormproof shelter to start a new life (para. 34). In other words, necessities can become a major issue in case of severe climate change. It is important to consider because everyone will need shelter, especially during extreme conditions. It affects entire populations because such a disaster will not skip a nation. Currently, experts would have to work on predicting the magnitude of the threat. Future generations might face highly difficult challenges that will require outstanding survivalist skills. Williams (2017) also claims: That is why many survivalists are placing their hopes of sustenance in rabbit, a high-protein, low-fat meat that is also being embraced as the new chicken by sustainable food types including Michael Pollan (para. 40). A drastic climate change can also reduce the overall availability of food. It is critically important because food is one of the key basic needs. It also affects all people and they would need to plan for potential shortages of food by strengthening supply chains. Future generations will be stroke the hardest, and finding food might become a daily problem for them. Nonetheless, shelter and food are no match to the dire consequences of water unavailability.

Water Shortage

Climate change is often associated with extreme temperate fluctuations, which can lead to water shortages. Young (2019) writes: Reduced water availability could affect up to 2 billion people (para. 5). This means that a significant part of the global population can experience the serious issue of not having enough water. Water is a necessity and it is more important than food. It will affect almost a quarter of the worlds population, which will lead to mass suffering and death from dehydration. Currently, it would lead to massive deaths in water-vulnerable African nations. Future generations will have no other choice than to find ways to purify oceanic water. Young (2019) also writes: Firstly, that drastic measures are needed to avert disastrous climate change. Secondly, extreme scenario planning is a necessity in the case that these measures are not undertaken  or arent enough (para. 6). In other words, the severity of climate change will depend on the actions that are being taken now. These extreme scenarios are likely if no preventative measures will be conducted. It affects the government and it would mean that officials and the public need to start acting immediately. Future generations will face challenges, and their severity will be directly reliant on the measure being undertaken now. Children of the future will most likely learn about many well-known animal species through museum representations of stuffed preservation, videos, and images.

Biodiversity

Climate change will inevitably hurt biodiversity all over the globe. Harvey (2018) writes: In Africa, it could cause some animals to decline by as much as 50 percent by the end of the century, and up to 90 percent of coral reefs in the Pacific Ocean may bleach or degrade by the year 2050 (para. 2). In the recent future, a significant portion of all animal species will be extinct. It is important because ecosystems rely on species interacting with each other by fulfilling specific roles. It primarily affects African nations, which rely on local animals as part of their ecosystem and tourist attraction. It would lead to severe ecosystem imbalances due to the loss of key species. Future generations might perceive elephants and lions similarly to dinosaurs  beasts of the past. Harvey (2018) also argues: Deforestation, the destruction of wetlands and other forms of land conversion can release massive amounts of carbon into the atmosphere, which may worsen global warming (para. 7). One should note that biodiversity loss also affects plants and deforestation will facilitate global warming. It will affect all nations, especially in the equatorial area, due to the high density of forests and higher temperatures. It would hasten the progression of global warming and biodiversity loss. Future generations will live in an environment with elevated levels of carbon.

Conclusion

In conclusion, if the world does not address climate change, workforce shifts, apocalyptic issues, water shortage, and biodiversity decline will occur, and we will end up with collapsed civilization. The article states: the researchers argue that the only way forward is establishing a worldwide zero-emissions, industrial and economic strategy (Young, 2019, para. 10). Humanity will probably survive drastic climatic changes, but the price for inaction will be manifested in mass death and suffering. People must stop living for short-term gains and start to prepare for the real and no longer political dangers of global warming.

Introduction

This essay will provide a discussion of the causes, effects, and possible solutions to climate change. The earths average temperature is about 15 degrees Centigrade, but sometimes it varies for several reasons, a fluctuation called climate change (National Climate Assessment, 2014). This alteration results in a lasting change in the global weather patterns, which defines the earths climates. The dilemma surrounding this issue is that economists and social scientists have opposing views regarding the actions needed to alleviate climate change. Although various disciplines have advocated for opposing approaches to reducing the impact of climate change, there is need collaboration in the formulation of a comprehensive policy towards tackling this issue.

The Dilemma Chosen

The chosen issue is climate change because it is a social dilemma triggered by human activity and will need joint efforts to reduce or alleviate its adverse effects. The primary causes of climate change include farming, deforestation, and fossil fuel burning, leading to adverse consequences which will need collective social responsibility to help lessen their effects (Romm, 2016). Climate change will require social sacrifice and adjustment to help address it and ensure the earth is safe for all living organisms.

The State of Social Science Knowledge on Climate Change

Causes of Climate Change

Many factors lead to climate change, but the main one is human activity, including farming, burning fossil fuels, and cutting down forests for farming (deforestation). These practices produce greenhouse gases such methane (CH₄), nitrous oxide, carbon (IV) oxide (CO₂), and chlorofluorocarbons that trigger climate change (Battersby, 2017). The gas which accounts for the most man-made-induced climate change is CO₂, with a 64% contribution, and since industrialization began, its concentration in the atmosphere has increased by 40% (Ge & Riedrich, 2020). This gas absorbs heat and traps it, making atmospheric temperatures rise abnormally. When this accumulated heat is re-emitted back to the earth, global warming starts, adversely affecting animal and plant life.

Additionally, clearing forests for human activities and farming increases the amount of CO₂ in the atmosphere. The plant cover has been identified as an essential aspect of balancing biodiversity (Romm, 2016). Trees absorb carbon (IV) oxide from the environment as they require it for photosynthesis. When plants are cut down, this absorption mechanism is hampered, thereby increasing the level of the gas, which causes climate change (Ge & Riedrich, 2020). Similarly, agriculture results in nitrous oxide and methane emission, which are greenhouse gases and cause climate change. For instance, nitrogenous fertilizers used in farming emit nitrous oxide, a greenhouse gas, contributing to climate change.

Consequences of Climate Change

The effects of climate change are divided into direct and indirect ones and are classified on how they impact humans and the environment. Direct consequences include rising of the minimum and maximum temperatures, which makes the globe inhabitable, and the melting of polar ice caps, causing a rise in ocean levels and temperatures (Romm, 2016). These extreme conditions endanger aquatic life is, and the overflowing water bodies may cause flooding in low lands, thereby leading to such public health and economic hazards as water-borne diseases, deaths, and destruction of property. Moreover, the high accumulation of CO₂ in the air makes a part of the gas to be re-emitted back to the globe, causing heat waves (Romm, 2016). These extreme conditions are likely to cause a sharp rise in the earths temperatures, which may lead to plant and human life death. Moreover, unpredictable weather patterns disrupt many human activities and adversely affect livelihoods. Therefore, the direct consequences of climate change can be very dire, which calls for adopting policies that will help alleviate the issue.

Conversely, indirect impacts include those that result from the aftermath of the alteration caused by climate change. The first one is hunger and food insecurity due to extremely high temperatures and unpredictable weather patterns (Romm, 2016). Crops usually grow at ideal temperatures, and some of them require a large amount of rainfall or water for irrigation. Global warming triggers fluctuation in the atmospheric temperatures, leading to unpredictable weather patterns that make it impossible to plant food crops (Romm, 2016). This results in a worldwide food shortage that leaves many people hunger-stricken, thereby threatening international food insecurity.

In turn, food shortage can lead to a dramatic increase in food prices across the world since only a small amount is available. The poor will starve and later die, or they will be forced to adopt those land policies that cause habitat loss and defragmentation (Romm, 2016). These practices adversely affect many nations desire to be self-sufficient. In some cases, people will be compelled to move away from flooded areas or those with extreme heat waves, leading to overpopulation of other regions. Therefore, the indirect effects of climate change may disturb many aspects of the worlds social and economic status and cause an imbalance in biodiversity.

How Social Science and Economic Disciplines Evaluate Climate Change

The economic and social science fields are in a conflict concerning climate change. The latter is opposed to the regulation, or even shut down, of the energy sector to ensure reduced emissions of CO₂, which is the primary cause of global warming and climate change (National Climate Assessment, 2014). Besides, the former has been adamant that the latters suggestion is outrageous and could make the world uncomfortable. To solve this stalemate, there is a need for both disciplines to collaborate and formulate a working policy that will help reduce climate change while having peoples livelihoods in mind. One looming issue is the low chance of humanity avoiding climate commons tragedy (Battersby, 2017). There has been a growing self-interest among individuals in transportation, overgrazing, and energy production, which has threatened the whole communitys good. An ideal way to ensure a balance between the economic and social sciences argument is adopting clean energy sources (International Energy Agency, 2016). This move will make transportation and energy production possible without having to use fossil fuels, which emits greenhouse gases, thereby preventing climate change.

Possibility of Some Solutions to Succeed

Some assessments and solutions are likely to succeed in addressing this dilemma. One of them is banning or reducing the amount of carbon (IV) oxide that escapes to the atmosphere (Ge & Riedrich, 2020). This can be done through reforestation since plants absorb CO₂ from the atmosphere to use during photosynthesis. One of the identified factors for the extreme accumulation of this gas in air is the cutting down of forests to accommodate human activities (Romm, 2016). Social scientists argue that this approach calls for collective responsibility to reduce the high concentration of greenhouse gases in the atmosphere.

Moreover, sociology suggests the formulation of policies to reduce carbon (IV) oxide emissions into the atmosphere since it is the leading cause of climate change. One way to do this is to ban or limit the use of fossil fuels as energy sources and adopt cleaner energy ones, such as wind power (Romm, 2016). Governments need to create a collaborative environment between social scientists and economists to help arrive at an amicable, balanced solution that will ensure a world free of climate change while supporting human activities.

Furthermore, such practices as excessive use of nitrogenous fertilizers and overgrazing have also caused an increase in methane and nitrous oxide gases concentration in the atmosphere. These can be controlled by limiting the number of animals that can be reared or the amount of fertilizer used for farming. According to Bradshaw (2014), it will require collective social responsibility to strictly follow these policies once enforced to ensure a planet free of climate change and is habitable for all its occupants. Therefore, climate change can be solved through global cooperation.

Why Climate Change is Solvable

Humanity and social scientists are up to the challenge and can help solve climate change. However, humans need first to accept the individual and joint efforts of ensuring they avoid the activities that lead to greenhouse gas production, leading to global warming and climate change (Hunt & Colander, 2016). The economic argument against the enforcement of these policies is a stumbling block for social scientists. This shows that the problem is solvable, but it needs to be done carefully without creating an imbalance (Hunt & Colander, 2016). For example, slowly switching to clean energy, such as wind, can help both sides of the dilemma to adjust before a total migration from fossil fuels can be enforced later. Thus, this dilemma is not insolvable, as some may view it.

Conclusion

To sum up, the essays purpose was to discuss climate change as a social dilemma: its factors, consequences, and possible ways of solving it. Human activities have been identified as the leading cause of global warming. The most notable practices include deforestation, farming, transportation, industrialization, and energy production using fossil fuels, which emit greenhouse gases when burned, triggering atmospheric temperatures to rise beyond the normal range, thereby causing climate change. Some solutions can be adopted to help solve this problem, including restricting or banning fossil fuels and embracing clean energy sources such as wind power.

Introduction

Global warming refers to an increase in the Earths average temperature that is characterized by rising global surface temperatures and the accumulation of pollutants in the atmosphere. According to scientists, it is the result of land surfaces heating faster than water bodies, an increase in atmospheric energy, and higher rates of evaporation that lead to extreme weather conditions (McCoy, 2019).

Main body

The major causes of global warming include greenhouse gases, land surface changes, and aerosols. Moreover, human activities like deforestation, farming, and burning fossil fuels also contribute to the phenomenon. Climate change refers to shifts in weather patterns across the globe that are characterized by changes in temperature, wind patterns, and precipitation that occur over an extended period (Ward, 2016). The main causes of global warming include livestock farming, burning fossil fuels, and deforestation. These activities lead to the accumulation of greenhouse gases in the environment, thus raising temperatures and causing a shift in weather patterns. Ozone depletion refers to the destruction of the ozone layer in the atmosphere (Nunez, 2019). It is caused by the release of solvents, propellants, and foam-blowing substances into the atmosphere, as well as sunspots and volcanic eruptions.

The three concepts are similar because they are aspects of environmental destruction that lead to changes in global temperatures and changes in weather patterns. Moreover, greenhouse gases are cited as a major cause. In many fields, global warming and climate change are used interchangeably because they are caused by similar sources. However, they have distinct differences.

Conclusion

Global warming refers only to the rise in surface temperatures while climate change encompasses both changes in surface temperatures and their effects that include melting glaciers and prevalent drought. Unlike global warming and climate change, ozone depletion increases the amount of ultraviolet (UV) radiation in the atmosphere. Its effects are more pronounced and include skin cancer, immune system damage, and eye cataracts.

Causes and consequences of global warming

It is generally accepted that the main cause of global warming is greenhouse gas emissions. The greenhouse effect resulting from heating the atmosphere with thermal energy held by greenhouse gases is a crucial process regulating the Earths temperature. Carbon dioxide (CO2) takes the largest share of all greenhouse gases, being responsible for global warming along with the others, for instance, methane and nitrous oxide. There are several reasons why these days there has been observed more air pollution than in the 20th century. First of all, it happens due to burning fossil fuels such as oil, coal, and gas at power plants, in internal combustion engines. The other roots of climate change are forest area reduction, decomposition of organic matter in waste dumping ground, and the booming livestock sector. Deforestation and reclamation of marshlands that could accumulate CO2 also enhance the climate crisis. Approximately 80,000 acres of rainforest are cut down every day, mostly for the timber or agricultural industry.

Climate change destroys all favorable environments in which human civilization has been developing. According to some estimates, human activity leads to a temperature rise of about 1°C compared with the pre-industrialized time (Donnelly et al. 15). Studies warn that if people are not able to stop the temperature increase by 1.5°C, the results will be disastrous (Donnelly et al. 26). Since the nature of the interaction processes is complex, it is difficult to predict what will happen. In fact, due to humidity and heat, the tropics become uninhabited for at least some time in the year.

Weather, agriculture, biodiversity, infrastructure will be under threat for the foreseeable future. In some parts of the world, hurricanes and floods are more likely to occur, while in others, the risks of droughts are growing. Concerning Sea Level Rise, whole cities and countries might go underwater, and other territories will become unfit for human habitation because of the extreme heat. A large part of glaciers in the Himalayas, which used to be the water source for more than a billion people, are likely to disappear (Gallina et al. 127). Billions of people can face severe water or food shortages; consequently, many of them can migrate to more inhabited areas. Food deficiency and lack of potable water also may cause an escalation of armed conflicts, increasing the number of refugees.

Climate change in terms of the social collapse

Denying climate change build up the likelihood of a global catastrophe. Human activity is considered the principal cause of global warming. The more rapid the development of technology is, the higher the burden people put on the environment. The methods of extraction of mineral resources, vehicles, and other technologies are being improved annually, but the environmental friendliness of their use is not proven. Hence people start asking themselves why humanity had never thought before about the possible environmental damage and how it turned out that peoples actions have led to the threat to all humankind?

It appears to forget the experience that happened a long time ago. Diamond illustrates it through the example of the Oil Crisis in 1973 when, for some years, Americans stopped using gas-guzzling cars (422). In contrast, nowadays, SUVs have become part of everyday life despite the 1973 event. Sometimes it is hard to see a problem through a whole sequence of reasons. Society makes bad decisions because of the failure to anticipate a problem before it arises. Secondly, after perceiving the problem, the attempts to solve it may be unsuccessful. According to Diamond, people wreak ecological damage out of ignorance, forgetting of the likely consequences (419). The problem of climate change is the most prominent example of the most typical circumstances when people cannot perceive the possible risks.

Global warming has a form of a slow trend concealed by wide up-and-down fluctuations. With large and unpredictable fluctuations, it has taken a long time to discern the average upwards trend of 0.01 degree per year within that noisy signal (Diamond 425). Climate change is climate variations of the Earth over time, expressed in statistically significant deviations of mean temperature from long-term values over millions of years. People can realize the changes only in a few decades. The term creeping normalcy, being widespread among politicians, refers to upward trends veiled by small fluctuations (Diamond 426). Another issue is the conflict of interest between politics and citizens, and the related phenomenon of climate change denial. It is a set of organized attempts to downplay, reject, or declare non-existent scientific consensus on the extent of global warming, its dangers, and its sequels based on commercial or ideological purposes.

Climate change is a global problem that cannot be solved by the efforts of one or more states. All countries should participate in the search for comprehensive solutions to this issue, regardless of the economic situation. It is necessary to be ready for climate change issues. By all means, adaptation measures are currently being implemented in the regions suffering from the consequences of global warming  these are, first of all, small island states and coastal areas. However, the list of risks from climate change for any country should encourage the authorities to adopt adequate plans to eliminate environmental harm. With the competent development and timely implementation of programs for climate change adaptation, it would be possible to reduce the damage and to derive some economic benefits.

El Niño Oscillation phenomenon (ENSO) is characterized by an increase in the ocean surface temperature in the eastern and central parts of the Pacific Ocean. It affects rainfall distribution and can strongly affect weather patterns in the United States and the rest of the world (Liberto, 2014). In general, I believe that it is challenging to predict the changes to ENSO influencing climate change because there are multiple contributing factors affecting it. Climate change can weaken or strengthen the weather pattern, which is associated with ENSO. For example, according to the article by Liberto (2014) in which the information from the Intergovernmental Panel on Climate Change is reported, usually, below-average rains take place across Indonesia. However, following the climate models, the amount of seasonal rainfall will increase in this area because of the temperature rise. This shows how the ocean and atmosphere can change and affect ENSO, which, in turn, will alter the weather patterns.

In the future, the emission of greenhouse gases will continue to escalate. Along with the internal climate variations, this will lead to changes in precipitation and temperature patterns in the upcoming decades. The areas which are affected by the increase in temperature undergo the most significant evaporative stress and become drier. As a result, there would be not enough moisture to buffer the activity of El Niño. Climate change will also affect the relationship between temperature and wildfire probability. In Libertos (2018), the Community Earth System Model represents that in the Southern region of the United States, the colder-than-average temperature was even cooler. This means that the anomaly of wildfire probability will reduce during El Niño in the following decades because of the connection described above.

The early history of any civilization is mostly concerned with creating a stable society, which often primarily revolves around finding a source of food. Climate plays an integral part in that process, as a deviation in heat and rainfall can mean the difference between a bumper harvest and a devastating famine. Feeding tens of thousands of citizens through hunting and foraging is not only unsustainable but impossible. Cultivating crops for the people and the livestock is the priority for any settlement.

Egypt is an example of such a static civilization that depends on agriculture. The Nile is the heart of Egypt for a reason: the waters and floods were harnessed by Egyptians to irrigate crops in an otherwise arid region. However, away from the riverbanks, on both sides, lay a desert (Tignor et al. 58). As such, when a drought began, the Egyptians faced a decline in their harvests, and the surrounding desert moved in. Because the Nile was Egypts sole source of both food and cultural identity, the drought produced an abundant literary record [&] full of tales of woe (Tignor et al. 97). The drought threw the nation into a deep decline, which it survived, but suffered greatly in the process.

The population of the Indus River Valley faced the climate change too but adapted very differently. The settlements of Indus River were weak, and they completely disintegrated, as people turned to nomadic lifestyles, looking for pastures to breed livestock. The Vedic nomads ventured outwards from their homeland, and obtained resources, among other ways, through conquest. Each wave of occupation involved violence, but [&] the confrontations led them to embrace many of the ways of the vanquished (Tignor et al. 99). The nomads grew their knowledge of farming and animal husbandry and applied their metalworking skills to drive technological progress in that area to survive and expand.

These two examples show how differently people can suffer from and adapt to climate change. The Egyptians enjoyed the bounty of the Nile and based their entire society around the river, so they could only persevere through a devastating famine. In contrast, the Indus River Valley settlers abandoned their settlements and expanded outwards, conquering agrarian societies and adapting their technology to survive. The lesson of the two examples is that, regardless of how a civilization adapts to climate change, it will be a drastic and often regressive change.

The author writes about an urgent need to reduce carbon emissions to prevent further global warming. However, he argues that individual actions are not effective in the struggle against climate change; what is needed is collective efforts (Adams, 2018). The article is retrieved from an online magazine that appears to be credible. The author is a principal lecturer in psychology at the University of Brighton. Additionally, he does not receive funding from any organization that could benefit from his article, which means that his arguments are unbiased. The author cites several sources and uses an example from the past to prove his point. This source is useful because it poses a challenge to the argument. Adams (2018) argues that, although individuals can change their behaviors to more sustainable ones, it will not be enough to stop climate change.

The authors analyze the major sources of greenhouse gas emissions in households. They suggest that individuals should be key actors in reducing greenhouse gas emissions, but there is a need for special policies encouraging individuals to change their behaviors (Dubois et al., 2019). It is a primary source since the authors conducted their original research. It is published in a peer-reviewed scholarly journal, which indicates that the source is credible. This article is useful because it proves that individuals play a significant role in addressing climate change. The statistics provided in the article are of particular value. Researchers state that 72% of greenhouse gas emissions come from households, especially such activities as car and plane usage, heating, and consumption of meat and dairy (Dubois et al., 2019).

The speaker argues that poor people are the first to experience the impact of global warming. She also provides a list of adverse effects that climate change has on health. She argues that healthcare professionals and politicians should educate people about how they can mitigate the impact of global warming on themselves (Holder, 2020). The author is a physician and president of the Florida State Medical Association, among others. She delivered her speech at a TED Conference and supported her arguments with examples from her rich personal experience. This source can be used to show the importance of the problem of climate change. The author argues that global warming leads to heat illnesses, asthma, allergies, emotional stress, and the spread of such diseases as Zika (Holder, 2020). This information will support the main argument by showing why individuals need to take action.

This publication describes the role of human behavior in addressing climate change. The authors propose behavioral changes that will mitigate the consequences of global warming (Williamson, Satre-Meloy, Velasco, & Green, 2018). This document is published by Rare, a non-profit environmental organization whose activity is concerned with helping communities adopt sustainable behaviors. The authors are experts in the topic they write about, and they use an extensive list of sources for references to support their claims. This source supports the argument by proving that individuals should change their behavior to mitigate climate change. Although one may feel hopeless at changing the world, it should not discourage one from taking action because if everyone takes responsibility for climate change, it will make a difference (Williamson et al., 2018). This argument can be used to respond to the counterargument that individuals efforts are not enough.

Human activities significantly affect the planets ecology and biodiversity in a highly negative way. Humans are responsible for the contamination of water and soil, and the emission of hazardous gases that deplete the ozone layer, create the greenhouse effect, and contribute to climate change (Lipczynska-Kochany, 2018). In other words, human activities will influence individuals, communities, populations, species, ecosystems, and ecological networks.

Climate change will have multiple negative effects on the planets ecology and biodiversity, including sea-level rise due to glacial melting, weather patterns change, and animal extinction. Extreme weather events will have a destructive effect on the planets ecosystem. While one area will be covered with water, other regions will suffer from droughts, heat waves, sandstorms, and wildfires. Mass desertification and water scarcity may be regarded as one more potential effect of climate change (Gosling & Arnell, 2016).

Moreover, people will suffer from all types of natural disasters and various infections, such as dengue fever and malaria, and food poisoning. All endangered breeds of animals will disappear, and millions of species that currently live will become extinct due to massive deforestation and a lack of fresh water (Urban, 2015). Moreover, climate change will decrease the populations genetic diversity due to rapid migration and directional selection that will hurt the resilience and functioning of the planets ecosystem.

As humans are constantly developing, evolution will continue after a million years as well. However, substantial climate change will affect the physical appearance, life span, and lifestyle of humans. For instance, human skin will become darker due to the increased level of radiation, as the ozone layer will not be able to protect the planet as before. A lack of oxygen will cause the enlargement of the lungs and the thoracic cage. In general, the glacial melting, multiple natural disasters, floods and droughts, and various infections may stop the development of humans and their technological progress. People will return to the primitive level of life that will be characterized by hunting and gathering. Life span will potentially decrease due to severe food poisonings and various infections.

The habitat of humans will significantly depend on the areas environmental conditions. Although the part of the population may adapt to life in the flooded territories, a prevalent number of humans will settle in terrestrial biomes. Constant natural disasters, such as tornadoes, hurricanes, and wildfires, will not let people construct high sustainable buildings. Moreover, communities will suffer from the shortage of food and fresh water, as climate change will result in glacial melting and ocean acidification that will negatively influence marine life and the entire food chain. In addition, a lack of supplies will be caused by rising sea levels that will destroy a substantial part of agricultural land.

Concerning the interactions between species and humans in particular, due to natural calamities and the spread of disease, the problem with the planets overpopulation may be solved in the future. However, people may be divided into separate groups, and the contacts between these communities will be substantively limited. Such segregation may negatively influence the genetic diversity of people. At the same time, the effects of climate change will have a substantial impact on wildlife as animals have insignificant chances to adapt to climate change in comparison with people. The extinction of numerous species and potential isolation caused by environmental conditions will affect the food chain as the balance between predators and prey may be destroyed in particular areas.

One of the most important issues at the border involving existence and ecological sciences is how ecological unit will react to worldwide alteration in the face of ongoing decrease of biodiversity. Owing to their possibility to stock up huge amount of carbon in biomass and to avoid soil decomposition, forests are of particular significance but not easy to control experimentally. Global warming has caused an increase in concern over how carbon moves though specific natural ecosystems.

In this study I described forest structure for two upland Florida ecosystems, sandhill and a mixed hardwood hammock forest, through means of quantifying tree diversity, basal area, frequency, and heights. Than to quantify the function of these systems I determined the carbon flux of a well established mixed hardwood hammock, lawn, and agricultural sites in order to note how human influence is changing the rate at which carbon is cycling though an ecosystem. In both of these studies used I used a belt transect to survey and collect data on tree diversity and characteristics.

Other tools that were used were clinometers, to determine tree height, DBH tape to determine tree diameter, and a Infrared Gas Analysis Chamber which was used to quantify the amount of carbon dioxide respired by plants and soil microorganisms. My results found that sandhill forest communities are less diverse than hardwood hammock communities and that forest were better carbon pools than lawns. I also discovered that the highest flux rate of carbon out of a system came from the area which was tilled every 40 years. In conclusion I found that forest store carbon very efficiently and that tillage is a good mechanism to speed up carbon flux out of a system.

The objective to put together the consequences from the two scheme part to achieve an improved mechanistic kind of how medium-term results of biodiversity loss on ecosystem performance may be connected to degree of difference of short-term reaction to environmental measures of forests with high vs. low tree diversity. This information outlines a base for management to increase forest steadiness and environmental maintenance, together with timber production and soil protection.

Introduction

The importance about the outlook of forests has mainly concentrate on the pressure to the continued existence of the strange biological diversity that set apart these ecosystems. An additional viewpoint highlights the responsibility that forests take part in the global carbon cycle. In spite of covering only about 8% of the ground level, forests are considered to control about 40% of the earthly biomass and allow for over 50% of the yearly net primary output of the biosphere (Williams et al., 1998).

In addition, current facts proposed that unlogged forests proceed as a sink of anthropogenic carbon discharge (Grace et al., 1995). On the other hand, the devastation of forests by land permission and forest fires is an important source of CO2, a point noticeably highlighted by the current huge fires that take place in forests internationally (Brown, 1998). The point of this review is to detail existing research relating to the issue that manipulates carbon dynamics in the forests.

Global warming has caused a heighten interest in the flux of carbon in and out of ecosystems in recent years. This spring of interest has been caused by the solidified statement that increasing carbon levels are directly related to anthropogenic carbon dioxide emissions. In this series of observational studies I will consider ecosystem function and structure and connect them to ecosystem carbon flux through means of biomass and respiration studies.

The objective for this research was to quantify tree diversity, basal area, frequency, and heights in sandhill and mixed hardwood forest ecosystems in attempts to describe their structure and secondly, to determine carbon flux though means of soil respiration in multiple Florida ecosystems and evaluate how changes in land use/cover could affect ecosystem cycling of the carbon.

Sandhill forests are arid fire climax communities that occur on elevated sloping ground composed of deep, marine deposited, yellowish sands that are well drained and relatively sterile. (Myers 1985) The vegetation consists mainly of longleaf pine (pinus palustris) deciduous oaks and with a typical ground cover of wiregrass (Aristida stricta) (Myers et al. 1987). Since sandills are a fire climax community they are dependent on low-intensity quick burns in order to reduce hardwood competition.

The larger pines and oaks over time developed thick insulating bark and developmental modifications that allow seedlings and seeds to be fire tolerant such as the grass like seedling stage of most pines (Myers, 1985). In Florida, this community has been extensively reduced and altered due to agriculture and development over the past 100 years. (Myers et al. 1987)

The second community I evaluated was a Florida mixed hardwood forest. These plant communities are found in areas where fire has been suppressed long enough to allow succession to move pass the pine stage and where limestone and phosphate deposits are outcropping ( Myers, 1985). Hardwood mixed forest varies highly in species composition since they are dependent on soil moisture and fertility. Therefore the most species diversity should be located in the mixed hardwood hammock rather than the sandhill environment because it is a more variable ecosystem that has more diverse soils and is less prone to selection by fires.

The main ecosystem function I focused on in this study was the flux of carbon dioxide from a Florida hardwood forest, lawn, an area that had been tilled every 10 years, and an area that had been tilled every 40 years. When plants photosynthesize they decrease levels of carbon in the atmosphere by collecting it via carbon dioxide and storing it in their biomass. Almost 50% of all living tissue accumulated in plants is comprised essentially of carbon so plant growth and photosynthesis are two direct causes of decreased levels of carbon dioxide in the atmosphere.

The process of respiration is another important mechanism which influences carbon flux by releasing carbon dioxide back into the atmosphere through processes of plant dark reactions and microbial and animal metabolic activates. Soil respiration, which is made up of organic matter decomposition and mineralization, root respiration and atmosphere respiration, is strongly influenced by temperature and moisture levels (Jabro et al. 2008) When soils are warm and moist microbial metabolic rates can increase allowing more respiration to occur than if they were dry and lower than ideal temperatures.

So the hardwood forest should have the highest amount of carbon storage because it contains the most plant biomass, while the plot of land that is plowed every 40 years should have the highest carbon flux rate because of the constantly aerated soils which allow high levels of microbial activity to occur to digest the grasses and shrubs with annual life cycles.

There is an obvious need of essential data on carbon storage in the woods and the amount of carbon released next to logging and burning. Carvalho et al. (1995; 1998) establish that a 1-ha area of forest hold about 200 tonnes of carbon in the above-ground biomass. A late dry period fire in wreckage three months following the forest had been vacant was set up to go through about 20% of the entire above-ground biomass and released 37.7, 121, and 8.6 tonnes per hectare of carbon, CO2 and CO, correspondingly. Kauffman et al. (1998) establish that the entire above-ground biomass of the main forest was between 290 and 435 tonnes per hectare and as soon as this biomass was cut and burned it dismissed, relying on restricted site conditions, between 58 and 112 tonnes of carbon per hectare.

The quantity of carbon stocked in forest soils in contrast to that stocked in forests transformed to cattle pasture remains uncertain. Assessment of accessible data led Fearnside and Barbosa (1998) to bring to a close that pasture adaptation naturally discharge about 12 tonnes of carbon per hectare in the forest, even though they note that the quantity of carbon stored or lost from the soil is predisposed by the method of pasture management.

The length of studies of transformed forest sites is necessary to give way to vigorous guess of soil carbon storage (Fearnside and Barbosa, 1998). There is also substantial indecision as to how forest soils will react to augmented CO2 and related climate change (Silver, 1998).

Evaluation of present facts led Silver to reason out that warmer climates features of a CO2-rich atmosphere will have an effect in increased soil respiration but it is indefinite how this will be counterbalance by increased carbon absorption by plants that will as a result return more organic matter to the soil. Silver (1998) comments that refusal in soil organic matter linked with increased respiration may affect the reduced ease of use of soil nutrients, therefore preventing the ability of forests to take the benefits of increased CO2 the so-called fertilizer consequence.

Methods

This investigation was conducted in the San Felasco Hammock State Preserve, where sandhill and a mixed hardwood forest arrange side by side. I used the belt transect to measure up the arrangement of sandhill and mixed hardwood forests. At every sample location, Id put up a belt transect that was 100 meters long by 10 meters wide (Schuur et al, 2008). Then I divided the 100 meter by 10 meter area behind the center of its extended axis with numeral pin flags at 10 meter interval.

The external limitations of the transect were then marked at 10 meter interval in order to form pin flag grid where every box, consisting of 4 flags, created a 10 meter by 5 meter plot. These plots where then given a consistent numerical scheme in order to keep path of sampling site information. Once the two divided transects were recognized in every place, I began to bring together tree height and inventory information for the individual 10 meter by 5 meter scheme within each transect.

While determining tree height, first I recognized the tree species and then stand in an identified distance away from the tree. Then by means of a clinometer I documented the point of view from eye level to the top of the tree. By using this data in addition to my own height information I used plain trigonometry to generalize each individual tree height. When taking tree record I collected data relating to plant species and its DBH or diameter at breast height in every individual plot of the belt transect for species of tree that were active and had a width at least 2 inches wide. (Breast height is believed to be located at just about 1.37 meters.)

To compute CO2 flux, I set up a single 50m transect in a mixed hardwood forest, grass, 10 year old field, and 40 year old field all located at the University of Florida outside training laboratory. Next to each transect, I obtained six 15 second measurements at 10m intervals using an infrare gas examination soil respiration chamber. These measurements were used to duplicate the soil respiration from each site.

With the intend of evaluating the above earth biomass in a hectare of lawn to a hectare of woodland, formerly I used to established allometric equilibrium to estimate above ground biomass of trees with pliable or firm wood foundation only on their stem diameter. This process was used given that it is less time consuming and did not necessitate the devastation of the area in query. B= a DBH^b Where B= biomass in tons, and a and b are constants values, and DBH= diameter at breast height (cm). Here are the constant values for the forest I used: Softwoods: (a=0.006, b=2.172), Hardwoods: (a=0.113, b=1.164). (Lab manual)

After that I measured every individual tree >2.5 cm DBH within 2m on either side of the transect, in 10m increment (Schuur et al, 2008). For the lawn and tilled plots I clipped and collected a 25 cm x 25 cm square sampling from the middle of every plot and multiplied this biomass number by 0.5 to get the quantity of carbon since biomass is just about 50% carbon. After computing the quantity of carbon at each plot I level this carbon into a 1 hectare area.

Results

The degree to verify the arrangement of every ecosystem I come across at I used a species-area curve. As the vicinity is reviewed in the mixed hardwood hammock increased, more species were noticed. Whereas in the sandhill species, the diversity is plateau at around 300 sq meters. The sandhill and hammock ecosystems together had declining basal area with an increase in tree number of trees (Fig. 2). In the mixed hardwood hammock ecosystem Laurel Oak (Quercus hemisphaerica) was the majority of influential species, with utmost relative significant value, relative supremacy, frequency and abundance (Fig. 3).

While in the sandhill ecosystem there was a relatively equal spread of importance between Loblolly Pine (Pinus taeda), Longleaf Pine (Pinus palustris), Slash Pine (Pinus elliottii) and Turkey Oak (Quercus laevis) while Laurel Oaks (Quercus hemisphaerica) though present were relatively non abundant (Fig. 4). When comparing tree height between the two ecosystems it was found that the hammock ecosystem (mean=17.977 meters/tree, variance 46.095) and the sandhill ecosystem (mean=18.715 meters/tree, variance 33.123) were on average very similar in height (paired t-test for means=1.833, p value one tailed =0.411).

When looking at ecosystem purpose in respect to carbon dioxide levels I found that forest had the largest carbon pools, while lawns had the smallest (Figure 5). Surprisingly, I found that the area that receives tillage every 40 years had the largest mean carbon loss at 39.48 Tons C/ha/yr with a St Dev. of 10.57. The lawn had the lowest mean carbon loss at 21.78 Tons C/ha/yr with a St. Dev. of 15.35 (Figure 5).

The longest turnover rate was found to be in the forest with it taking 65.31 years for carbon to return to the atmosphere. The shortest turnover time was held by the 40 year tillage patch with a turnover rate of 0.25 years. The largest biomass amount was found to be located in forests which had an average of 2329.797 Ton C/ha (St. Dev 2103.05). The lowest amount of biomass was located on the lawn with an average of 1.407 Ton C/ha (St Dev. 0.781).

Discussion

It has been discussed whether worldwide climate change and associated increased in CO2 height will have effect in considerable adjustment in the arrangement and group mixture of forests (Phillips, 1995). Roden et al. (1997) used a growth hall to replicate the outcome of a tree-fall hole on the growth of a pioneer species and a late sequences species from the subtropics in a CO2 rich environment. They discover that increased CO2 considerably deferred the capability of the shade-tolerant species to adapt to high light levels whilst the pioneer species was not so deprived. Such outcome flags the likelihood that under a CO2-rich atmosphere, pioneer species may proceed as a negative reaction system in the global carbon series since their ability swiftly to collect carbon in plant biomass and soil (Bazzaz, 1998).

Though, beneath a very deep shadow situation it has been revealed that one species of neotropical forest bush had larger growth and absorption rates in growth chamber with twice the present atmospheric property of CO2 in contrast to growth chambers with the surrounding atmosphere (Winter and Virgo, 1998). The dimensions of gas exchange of forest in the Biosphere 2 mesocosm have also made known to elevate carbon absorption under increased CO2 (Rosenthal, 1998), a outcome that proposed that forests may be a vital sinks of anthropogenic CO2.

On the other hand, countryside testing has shown that the reaction of plants to improved CO2 is more complex than many growth chamber trials suggest. For example, Lovelock et al. (1998) found that eminent CO2 resulted in no increase in plant biomass of ten neotropical forest tree seedlings from three sequence phase developed in open-top chambers generated in the ground. These authors perceived considerable modification in leaf chemistry in reaction to elevated CO2 and mainly where late rotational species had better leaf carbon to nitrogen proportion. This directs them to reason out that the outcome of high CO2 on forest may perhaps be indirect by means of change in nutrient interval and therefore soil nutrient accessibility.

Modelling is crucial to the knowledge of forest carbon financial plan, chiefly at local and worldwide balance. Though the forecast of representation are of basic necessity, given the difficulty of the connections and poor geographical extent of field statistics, they are practical in putting together suggestions and elucidating field measurements (Potter et al., 1998). For instance, a form of the soilplantatmosphere range was matched over ground measurements of CO2 and H2O found on eddy-covariance techniques in a virgin forest.

This model led Williams et al. (1998) to terminate that lesser carbon uptake in the dry season was due to reduced soil moisture materials, rather than due to change in leaf region indicator or low levels of moisture. Information on constant isotopic arrangement of carbon and oxygen in CO2 example across vertical outline during forest covering are believed to be crucial for rising global carbon budgets. Nevertheless, much more investigation is necessary to comprehend the foundation and implication of temporal and spatial inconsistency in these measurements (Buchmann et al., 1997).

The Biosphere 2 mesocosm has facilitate investigational validation of straightforward canopy representation used to discover the result of different levels of CO2 and light on net carbon uptake of the forests (Lin et al., 1998). This mesocosm facility permits the creation of data on carbon exchanges under a range of mixture of light and CO2 distribution that at present do not take place under normal conditions. Lin et al.s (1998) short-term testing and modeling led them to determine that carbon exchange is not in a straight line and that previously atmospheric CO2 levels exceed 600ppm in the forest cannot act as a carbon sink.

This judgment is reliable with the soilvegetationatmosphere modelling by Cao and Woodward (1998) for the period 18612070. They established clear interaction consequence of climatic change and increased atmospheric CO2 on carbon storage and recommended that in the tropics the harmful consequence of climate change on carbon result will be counterbalance by more well-organized gas exchange under an ambiance enriched by CO2. On the other hand, they foresee that the capability of earthly scheme to store carbon would turn into concentrated once CO2 strengthening surpasses 600ppm.

Laurance et al. (1998) take on a modelling exercise to examine the significance on carbon discharge that biomass decline is greater on the limits of forest fragments in contrast to the entire centre of remains. Their modelling established that land interval that create numerous rain forest segregate (such as that caused by small-scale farms) causes two to five times more biomass decline on forest border than separation for large-scale cattle ranches, in spite of the total area cleared.

They recommend that this distinction is a major additional section of global carbon release that has been in the past unnoticed, perhaps in the order of 22149 million tonnes per year for forests worldwide. Goldammer and Price (1998) used the outcome of a number of models of the importance of climate change following a repetition of atmospheric CO2. They accomplished that forests, mainly those ruined by logging and clearance, will develop into more fire prone given extended dry seasons, high frequencies of dearth and an increased significance of fires started by lightning. Recurring fires may affect considerable soil nutrient losses from minor forests, thus striking the capability of forests to take carbon (Kauffman etal., 1997).

Conclusion

In a current evaluation Bazzaz (1998) renowned that there can be little doubt that forests will react to increases in atmospheric CO2 and related alteration in rainfall and temperature, even if accepting the particulars of these modification will necessitate substantial mutual research from scholars across a wide variety of regulation.

Houghton (1997) exemplify this position by disagreeing that, in order to undertake sufficiently the problem of carbon exchange amid the atmosphere and biosphere, the subsequent five research programmes that function at unusual spatial balance should be engaged:

1. direct field measurements of carbon storage;
2. direct field measurements of CO2 fluxes above different ecosystems;
3. models of carbon cycling at the ecosystem level;
4. geochemical modelling of the global carbon cycle; and
5. modelling carbon flux on the basis of remote-sensing data on land-use changes (Bazzaz, 1998).

Obviously, to carry out such a complete set of research programmes the decision of an amount of considerable scientific, managerial and political problems is requisite. This is so since the worldwide nature of the question, the variety of methodologies and expertise, and the vast quantity of information concerned (Houghton, 1997). Additional, such included programmes are costly and need strong community support in a broad cross-section of rich and poor state all through the world.

Mazur (1998) offer a sobering report of the indecisiveness of the media in gathering together worldwide community support for forest protection. In spite of speed up there is proof devastation of tropical rain forests and matching release of CO2 that this once well-liked media story has now turn into decayed. Recurring the fortune of tropical rain forests to the pinnacle of political program entail change in media attention to update the public and reason politicians.

With no extensive support there will be inadequate assets to undertake this grimly serious worldwide crisis. One more urgent subject crucial for the continued existence of forests is the making of financial device that make rich nations pay for ecological services provided by forests, such as carbon storage (Fearnside, 1997). At present, ecological services significant to the preservation of biosphere purpose are not accorded financial cost with the effect that poor nations have no financial inducement to relinquish the change of forests in their anxious mission for hard notes.
