Global Warming Essay Material

In the last 50 years, human activities such as excavating the earth, use of fossil fuels and greenhouse emissions have drastically altered the earth’s climate in negative ways. During this period of time, the burning of fossil fuels has released large quantities of carbon dioxide and greenhouse emissions which in turn have trapped heat in the earth’s lower atmosphere thereby affecting our global climate.

The humanity is and has always been connected with all the life cycles of the surrounding world. But since the emergence of highly industrialized society, the scope of damage that people do to nature has grown rapidly. Consumption of non-renewable mineral resources constantly intensifies. More and more arable lands drop out of use as cities and factories are built on them.

As a result of the population increase, intensive industrialization and urbanization of our planet, economic pressure began to exceed the ability of ecological systems to self-purification and regeneration. A natural cycle of substances in the biosphere was disrupted. The health of present and future generations of people is under threat! This is one of the most important and frequent global warming thesis statement ideas.

Ecological problems of the modern world are not only acute but also multifaceted. They are caused by virtually all branches of material production and are relevant to all regions of the planet. The Earth’s biosphere is currently exposed to serious anthropogenic impact. There is a number of processes worsening the ecological situation: in particular, the world is getting warmer and humanity is largely responsible for this, experts say. But many factors affecting climate change have not yet been studied. Scientists and students analyze this topic thoroughly.

Causes of warming to be described in research papers on climate change

The greenhouse effect has been a serious problem for several decades now. Without it, the temperature of the atmospheric surface layers would be on average 30 degrees lower than the actual one. However, in the last decades, the content of some greenhouse gases in the air has significantly increased: the percentage of methane has grown 2.5 times and that of carbon dioxide – by more than 1/3 of its previous volume.

There are also new harmful substances which simply did not exist earlier; primarily, these are chlorine- and fluorine-hydrocarbons including the notorious frons. The link between global warming and air composition change is quite obvious. Moreover, the reason for the rapid growth in the amount of greenhouse gases is also clear: our entire civilization, since the bonfires of primitive hunters to modern gas stoves and cars, has utilized the rapid oxidation of carbon compounds, the final product of which is CO2.

Human activity is associated with an increase in the content of methane (rice fields, livestock, leaks from gas pipelines) and nitrogen oxides. Perhaps, people do not yet have a noticeable direct effect only on the content of water vapor in the atmosphere.

CO2 problem

Among the global environmental issues facing humanity, the problem of CO2 is one of the most controversial. Many consider it to be a far-fetched one. Yet, there are real signs of global warming and forecasts by some climatologists and physicists who affirm that the situation is about to get a lot worse. In their opinion, it should happen because of the accumulation of carbon dioxide of anthropogenic origin in the atmosphere.

In the Quaternary period, which includes our time, the content of CO2 in the air is very low. But the pace of accumulation of this gas in the atmosphere is unprecedentedly high. That’s why most of the climate change essay topics revolve around this issue.

Nowadays, most researchers consider the combustion of fossil fuels as almost the single reason for the CO2 volume increase in the air in the X – XX centuries. In the XXI century however, there are deforestation, agricultural pollution, overgrazing, and a number of other factors that have negative effect on the and vegetation cover of the Earth.


One should pay special attention to this phenomenon when writing a reasons of global warming essay. Deforestation for the sake of building construction, mining, creation of water reservoirs, and repurposing of forest lands into agricultural ones is considered the most significant factor leading to the permanent loss of organic matter in the biosphere. Up to 25% of the carbon dioxide got to the atmosphere due to deforestation. The issue of deforestation and burning of fossil fuels are roughly equal now as for the scopes of ecological damage they do to our planet.

Degradation of forests occurs on the background of excessive recreation activities and tourism, air pollution, and a number of other cases (intensive grazing, flooding of the terrain, drainage of nearby swamps, etc.).

Through the observations it was established that even an insignificant load causes changes in the soil-vegetation cover. Soil compression carried out in forests and parks leads to a decrease in the mass of roots due to which the trees’ growth stops. As a result, they become smaller and the branches become thin and short.

Mechanical damage to forests leads to the development of diseases and increase in the population of pests. When natural territories are visited by large groups of people, the lower tiers of vegetation die, the soil litter is trampled, and the humus layer suffers. Organic matter is reduced by 50% or more in parking and recreational areas.

Significant air pollution is one of the main reasons for serious forest degradation. Fly ash together with coal and coke dust clog the pores of leaves, reduce the access of light to plants, and weaken the process of assimilation. Poisoning of the soil by the emissions of metal/arsenic dust in combination with superphosphate or sulfuric acid affects the root system slowing down its growth. Sulfurous anhydrite is toxic to plants. The vegetation is completely destroyed under the influence of smokes and gases of copper smelters in close proximity. 

Significant damage to the forests is caused by the acid precipitation connected with the spread of sulfur compounds into hundreds and thousands of kilometers. A great decrease in forest biomass is also associated with fires.


Nowadays, agricultural activities include processes leading to a rapid reduction of humus in soil and the release of CO2. Agriculture-provoked pollution can be considered as one of the most significant factors that lead to global warming and one of the main climate change research topics.

Most of humus is lost as a result of severe erosion and weathering. In addition, the cultivated lands lose this natural fertilizer due to its oxidation during the plowing and burning of vegetation in the framework of the slash-and-burn agriculture system. The constant loss of humus is also observed when nitrogen reserves are depleted in the soil. In developed countries, nitrogen depletion is compensated by using mineral nitrogen fertilizers and cultivation of leguminous crops.


Excessive grazing in tundra, forests, and especially in meadows leads to the destruction of the land. This problem can also be discussed in a causes of global warming essay. Currently, overgrazing is particularly damaging the ecosystems of Africa, Eurasia, Latin America, and Australia. Simultaneously with the desertification, the soil with its organic matter is gradually removed.

Bogs drainage

Drainage leads to the oxidation of organic substances accumulated in peat bogs. This also leds to greenhouse effect and may be mentioned in your global climate change essay outline. When removing the 1-meter layer of marsh water from 1-hectare area, dozens of tons of dissolved organic matter are released.

Possible consequences: points to discuss in argumentative global warming essay

There would not be so many global warming essay examples if humanity was not afraid of the possible consequences of this phenomenon. If current tendencies remain unchanged, the carbon dioxide content in the atmosphere will double by 2060 (compared to the pre-industrial level) and quadruple by the end of the century. This is an extremely disturbing fact because the life cycle of CO2-emissions in the atmosphere is more than a hundred years. For comparison, water vapor has an eight-day cycle.

Modern predictions are based on the idea of a dynamic equilibrium among all components of the natural environment and the danger of its breaking. In particular, anthropogenic warming of the climate system as well as the decrease (or even disappearance) of snow and ice masses in high latitudes and at the poles of the Earth will significantly weaken the meridional atmospheric circulation and, as a result, lead to the moistening of the continents. Over the past 250-300 years, the level of the World Ocean rises by an average of 1 mm per year.

It is worth mentioning in your effects of global warming essay that the predicted changes should be observed to the biggest extent in the Arctic and Subarctic. Degradation of permafrost and ice rocks can occur in these zones. All cities, towns, and communications built on such territories are under the threat of destruction.

There are lots of reasons to believe that radical climatic shifts and the melting of glaciers may affect the processes in the depths of the earth. Due to the redistribution of water masses from the poles to low latitudes, the Earth’s rotation speed will slow down imperceptibly. Will such impulses stimulate volcanism and earthquakes in the Сircum-Pacific belt, the Mediterranean, and other seismically active zones? In case the disintegration of the West Antarctic Ice Sheet continues at the same speed, the level of ocean water will grow rapidly by 5-7m and this may be enough to provoke volcanic processes in the most seismically active areas.

It will lead to flooding of the continental edges and change the geography of their wet and arid zones that will influence the underground hydrosphere. Will the uplifting and lowering of the Earth’s crust in the zones of growth and reduction of natural water horizons be accompanied by the seismic activity? The available data on anthropogenic subsidence and uplifts of the Earth’s surface exciting seismicity denote the possibility of such events.

The delicate balance among the Earth’s shells that is maintained by slow geological processes can be disrupted for hundreds of years. These changes will undoubtedly cause great damage to the world economy, although the technical advancements of mankind are expected to help us resist it. Therefore, the measures must be taken to counteract the increase of atmospheric CO2 concentration and provide safety for the biosphere and humanity. That’s why the investigation of climate change paper topics by scientists and students is so important.

Given the data collected from all over the world and the results of the UN Commission’s studies, the average temperature may rise by 1.4-1.8 degrees Celsius during this century. The level of the World Ocean will increase by 10 cm, jeopardizing the countries that are located lower than the sea level.

Given the influence of mankind on the environment, the Intergovernmental Panel on Climate Change (IPCC) insists on increasing the number of observations to create a more precise picture of global warming.

UN report

The United Nations has a great influence in various parts of the world so you have every reason to take the opinion of the UN experts into account. Unfortunately, most of the conclusions and predictions of specialists are disappointing; according to them the negative results of warming will be seen almost everywhere.

For most of Europe, the threat of floods will increase significantly. The glaciers of the Alps and large areas of permafrost will begin to melt and completely disappear by the end of this century. However, the climate change will have a positive impact on the crops harvested in Northern Europe and almost equally negative effect on the agriculture of Southern Europe. This area will suffer from constant droughts in the 21st century.

In Asia high temperatures, droughts, floods, and soil erosion will cause irrecoverable damage to the agriculture of many countries. A rise of sea level and strong tropical cyclones will force dozens of millions of people to move away from the seashores. Approximately the same conditions will be observed in Africa. Crop yields will be considerably reduced; the amount of available drinking water will decrease. There will be less precipitation, especially in the south, north, and west of the continent. As a result, the emergence of new desert areas will become a common issue. Settlements in Nigeria, Senegal, Gambia, Egypt, and the ones along the southeast coast of Africa will suffer from rising of the sea level and coastal erosion. Epidemics of infectious diseases spread by insects such as mosquitoes will occur.

In North America and Australia, some regions will benefit from warming because agricultural activities will become more profitable there. However, all the other regions may suffer from various disasters, including floods, droughts, and epidemics. The amount of rains on the whole planet may significantly decrease, but the appearance of deserts and storms may become more frequent. In a few years, we will all run the risk of getting into an unfamiliar and frightening world in which the threat of pernicious infections will loom over mankind. The warm and humid climate that will be formed on the planet during the next 20 years will help dangerous diseases such as malaria or Dengue fever (already presenting a serious threat to humanity) to conquer new frontiers.

The small island states will suffer the most. It will be difficult for the developing countries to adapt to new conditions. Nevertheless, some positive effects, such as the increased timber production, lower deaths rates because of frosts during winter time, and large grain yields in such regions as Southeast Asia and Northern Europe are also expected.

Scientists warn that the predicted climate changes can potentially lead to large-scale and irreversible transformations: a slowdown in the supply of warm water to the North Atlantic, rapid melting of ice in Greenland and western Antarctica, and an increase in the proportion of carbon dioxide and methane in the atmosphere.

. The UN experts state that the signs of alarming processes are already visible:

  • The ice cover of the Arctic decreased by 10-15%.
  • Between the mid-1950s and the early 1970s, the ice on the Antarctic coasts retreated south by 2.8 degrees longitude.
  • When the average temperature increases by one degree Celsius, the Alaskan forest zone shifts 100 kilometers to the North.
  • The ice cover of lakes and rivers in the middle and upper longitudes of the Northern Hemisphere now holds for 2 weeks less than in 1850.
  • In Europe, some mountain plants migrate upward at a speed of 1-4 meters per decade.
  • Migratory birds fly north earlier and stay there longer.

Ways of solving the greenhouse effect problem

  • to identify the causes of climate change, monitor them and eliminate their consequences.
  • to reduce fossil fuel consumption, especially coal and oil, which emit 60% more carbon dioxide per unit of produced energy than any other fossil fuel;
  • to use special tools (filters, catalysts) to remove carbon dioxide from the automobile exhausts, emissions of smoke pipes of coal-burning power plants, and factory furnaces;
  • to create more expedient heating and cooling systems in new houses;
  • to increase the use of solar, wind, and geothermal energy;
  • to stop/slow down the process of deforestation and degradation of natural territories;
  • to remove storage tanks for hazardous substances from the coastal areas;
  • to expand the areas of ​​existing nature reserves and parks;
  • to apply regulations preventing global warming;
