Students in the school are generally get this topic to write some paragraphs or essay. We have provided some paragraphs and essays within different words limit in order to help students.
Global Warming Causes and Effects Essay 1 (100 words)
Global warming is a major concern nowadays because of the regular increasing temperature of the whole atmosphere. It is continuously becoming so powerful like a demon. There are many reasons for its ever increasing nature. The major cause of it is greenhouse gases like carbon dioxide, nitrous oxide, methane, chloro fluoro carbons, etc which are increasing in the environment mainly by the human activities. Some of are increasing number of automobiles, mushrooming industries, fossil fuels combustion, etc. Such activities emit more CO2 in the atmosphere which enhances global warmth of Earth. This increasing atmospheric temperature causes glaciers to melt, health disorders to occur and invites so many natural disasters.
Global Warming Causes and Effects Essay 2 (150 words)
As every one of us knows that couple of century, the climate on this planet was colder than now. And it is so surprising that even now it is not stable, it is increasing day by day. We are well aware and imagine its negative effects on our environment and body health. However, we are ignoring and continuing our bad habits which is flaming the global warming. Global warming is a constant process of increase in the annual temperature of whole planet. According to the statistics, it is recorded that in the last century the average increase in temperature is 0.7°C and sea level by 10 cm.
All the effects of the global warming (adverse effect on agriculture, floods, droughts, soil erosion, hurricanes, etc) are the huge indication of danger to our life. The main causes of the global warming are increasing human population, deforestation, increasing effects of green house gases, many careless human activities, etc.
Global Warming Causes and Effects Essay 3 (200 words)
There are many causes of the global warming which affects human lives and health in many aspects. The main cause of global warming is the human beings careless activities. Ever increasing human population are demanding more resources to live easy and healthy life such as land to live and crop cultivation, technological growth for comfort and deal with increasing temperature of atmosphere, etc. Fossil fuels burning for many reasons are highly responsible to increase global warming. People are realizing well the increase in environmental warmth however never mind their activities which are stimulating the global warming to increase. Continuously they are wasting natural resources and polluting the air, water and soil.
Increasing inventions of the technologies such as refrigerator, AC, car/automobiles, electric machines, oven, microwave, washing machine, etc because of the increasing need of human beings for technologies in order to make their life, easy and luxurious. All such resources ultimately contribute to the global warming. Burning fossil fuels in the automobiles emits various green house gases which get collected in the atmosphere and force it to heat. Increasing need of land by human being results deforestation which contributes to increase in CO2 and decrease in oxygen. It affects the human health, life style, calls diseases, calls natural disasters like hurricanes, heat waves, drought, climate change and so many.
Global Warming Causes and Effects Essay 4 (250 words)
Increase in environmental temperature and climate change has become very clear over the last 50 years because of increasing level of greenhouse gases concentration (like water vapour, CO2, methane, ozone, sulphur and nitrogen gases, etc ) in the atmosphere. Such as greenhouse gases contribute to increase in the greenhouse effect. The major cause of increasing greenhouse gas in the environment is burning of fossil fuels which emit carbon dioxide and heat the atmosphere. Such green house gases have capacity to absorb more heat from sun, heat from electricity used by human beings in many ways which in turn warm the whole atmosphere of this planet. The effects caused by the greenhouse gases (water vapour, CO2, methane, ozone, nitrous oxide, hydro fluorocarbons, sulphur hexafluoride, per fluorocarbons, chlorofluorocarbons, etc) are called as the green house effect.
Heating of the environment increases atmospheric temperature (by 3° to 5° C by the year 2100), increases sea level (by 25 meter by year 2100) and heat, melts glaciers, increases health disorders, changes climate, changes weather, increases annual power of hurricanes, calls natural disasters (floods, heat waves, droughts, tornadoes), lowers down amount and quality of agricultural yields, enhances glacial retreat, reduces summer stream flows, extinctions of various important plants and animals species and so many. There are some other dangerous effects of the global warming which continuously affects the lives of human beings, plants and animals. Global warming needs to be solved urgently by the active effort of each and every human being living on this planet.
Global Warming Causes and Effects Essay 5 (300 words)
Scientists and economists of many countries are working regularly in the field of global warming from many decades in order to figure out causes, effects, preventions measures, and solutions of it. In the last few decades, a huge level of change in the climate and weather has been seen clearly. It has disturbed the natural cycles and ecological balance in the atmosphere. The most important cause of increasing global warming is the effect of greenhouse gases which are emitted by human activities. In order to work together and solve this issue by the global effort, there is a group of scientists formed by the United Nations (Intergovernmental Panel on Climate Change or IPCC). This group works together to research the various causes, dangerous effects, effective prevention measures, and effective solutions.
According to the research and report of various highly skilled scientists, it is noted that ever increasing level of several greenhouse gases are highly responsible for warming of atmosphere. Combustion of fossil fuels by various means such as automobiles, cars, factories, electricity use, etc are responsible for emitting various green house gases like carbon dioxide, gases of sulphur and nitrogen, etc. Other contributors of the green house effect are methane (released by means of landfills, agriculture, digestive systems of grazing animals), nitrous oxide from various toxic fertilizers, gases released by means of refrigeration and industrial processes, loss of forests, etc.
The release of various toxic greenhouse gases in the atmosphere is increasing the atmospheric temperature as they have heat trapping abilities.
Methane gas molecules (20 times) and Nitrous oxide (300 times) have more ability to trap heat than CO2. In many countries the use of chlorofluorocarbons has been banned because they also have ability to degrade the ozone layer (a protective layer in the atmosphere) as well as high potential to trap heat thousands of times more than CO2. Other causes of global warming is deforestation which increases CO2 level, decreases oxygen level, drought, disturbs ecological balance, changes climate and changes weather patterns.
Global Warming Causes and Effects Essay 6 (400 words)
Global warming is increasing day by day because of the continuous increase in the levels of greenhouse gasses. Such gases have tendency to trap heat from many sources like sun, electricity, burning coal, burning fuels, etc and prevent them to escape back to the atmosphere. Thus, the collective effect of all the green house gases increases temperature on the earth and gives rise to many dangerous problems. Earlier, the earth was so cool and every natural cycles were going timely however nowadays lots of dramatic fluctuations in the weather, climate, temperature, health, etc takes place. A vast increase in the temperature, sea level, and weather patterns has been seen clearly in few last decades.
All the changes because of the ever increasing global warming are not a coincidence however it is caused by the human activities and technological advancement. A little fluctuation in the level atmospheric carbon dioxide may cause high level significant effect on the global temperature. The continuous rise in the percentage of atmospheric carbon dioxide is alarming us by its dangerous effects however we are still ignoring. Increasing need of fossil fuels (such as coal, oil, and gasoline) by the people of industrial civilization is giving the opportunity to rise in carbon dioxide emissions.
Deforestation is also causing increase in the carbon dioxide through decreasing number of plants and exposing soil to the sunlight. Trees are best source to absorb CO2 from the atmosphere however what happen if we finish the main source of reducing CO2 level. Our mal practices just to live luxurious life on daily basis are hugely altering the environment as well as endangering the lives of people in return. A little rise in the level of green house gases may hugely affect the global warming.
The use of a chemical called chlorofluorocarbon (CFC) in the refrigerators, aerosol spray propellants are continuously damaging the ozone layer thus increasing the chance of heat to remain on the earth by preventing them to escape back out to the environmental surface. Destruction of ozone layer increases the incidence of many health disorders and diseases such as skin cancer, respiratory disease, low immunity problems, etc. Global warming is damaging seasonal crops and marine food channel web, etc. It has affected the weather patterns (summer season has increased and winter season has decreased) and climate because of the increasing temperature and heat of the earth atmosphere.

Page 1 of 9 The Economic Effects of Global Warming Friday, May 19th, 2011. CIA 4U1 Mr. Phelan Page 2 of 9 The Economic Effects of Global Warming Today, global warming is becoming more and more volatile to the earth and has caused economic effects. Billions and billions of dollars have been lost due to the outcomes of global warming and its many causes. Climate change is evident and continues to change weather patterns, which cause negative outcomes. The biological systems, natural disasters, and pandemics are all causes of global warming and have hurt the economy. There regulations that can help push the economy in the right direction, but individuals must do their part in order for it to be a success. The process of climate change has had a negative economic impact on the world’s economies. The climate on our earth is continuing to rise and as a result, our biological systems are being affected. The biological systems include: croplands, forests, oceans, and fresh water. All of these resources benefit our economy and without them there would be huge economic problems. These resources are a source of income and without them, many different industries would be affected. Global warming has had a negative impact on our biological systems and has definitely proven to be an economic problem. As a result of warmer temperatures, agricultural sectors are being affected. The warmer temperatures decrease the amount of arable land and cause a decrease in soil moisture. Global warming has affected our weather and has resulted in the lack of rainfall some areas receive. Without rainfall, agriculture is impossible and droughts will lead to more loss of land. This has happened in the past with the Great Depression in the 1930’s.1 Agriculture was dry and areas received little rainfall which caused economic loss to the economy. Droughts are becoming more and more evident across the world which has 1 "Global Warming: The Economic Effects." Global Warming Causes & Global Warming Effects. 2007.

Fibre, vegetable oil, and corn are just a few of the resources that are supplied by agriculture. The food industry; especially vegetation industry, relies on agriculture to give them a source of income. Prices of food are increasing because there is less supply. Since 1970, drought conditions have doubled and heat waves have reduced the grain harvest in places like India, Canada, and the United States. Climate change is having a negative impact on our agriculture sectors, which is resulting in economic problems. People are beginning to experience food scarcity and furthermore noticing a market that is becoming unstable, less efficient, and more expensive. Food scarcity is becoming more evident which poses as an economic problem. Industries are losing more and more money which does not seem to be a good thing for our economy’s future. 2 The forest industry is very important to our world because it supplies us with raw materials that we use every day. For instance, fuel, lumber, and paper are valuable assets that come from trees. 3 With the increase of temperatures and lack of rainfall in some areas, trees will not continue to grow. The future of the forest industry is in great danger due to increasing temperatures. Logging industries and paper companies desperately rely on trees because that is essentially their whole industry. Huge incomes are gained through the forest industry and also these industries provide services to people or they supply people with raw materials that they use. Trees are very valuable to our economy and have a very strong market. 2 Geographic, National.

Page 4 of 9 Lastly, oceans and fresh water can both be linked to economic losses in our world’s economies. With climate change there are increased rainfall in certain areas and increased temperatures in others. When there are more heavy storms there is more chance that there will be floods associated. Floods and tsunamis prove to be huge problems because of the economic damage they cause. Increasing temperatures are not good because the warmer it gets the warmer water gets. When water gets warmer it begins to expand and could potentially move towards coastal areas where they can cause economic damage. Ice glaciers are melting due to warmer temperatures and some areas will face shortage of fresh water due to this. The Himalayas get forty percent of their fresh water from the rivers flowing in the glaciers. Over time the glacier have melted which caused a shortage of fresh water supply. 4 The economy relies on these biological systems for money supply and to overall increase the efficiency of the economy. Climate change is proven to be a threat and has affected many industries such as: agriculture, forestry, and oceans/fresh water. Something must be done to help stabilize the economy and to prevent climate change from having such a negative impact on our economy. These biological systems; due to climate changes, can create natural disasters and diseases that will continue to negatively impact our world’s economies. The process of climate change has had a negative economic impact on the world’s economies. Natural disasters and pandemics are both affected by global warming and have had an economic impact on our world’s economies. Natural disasters are terrible and result in millions of dollars in damages. Many diseases have been introduced due to rising temperatures. This causes a decrease in population and less production in our economy. Natural disasters include: hurricanes, tsunamis’, earthquakes, and floods. These disasters can potentially lead to a huge economic loss and have proven to do so in the past. Not only is the economy 4 An Inconvenient Truth. Perf. Al Gore. Documentary. Page 5 of 9 affected by the destruction of homes, businesses, and companies, but by the death of human beings. Many people die from natural disasters and these people are business employees, home providers, and otherwise important for our economy to function. With a decrease in population there would be less production in the world’s economy.5 Natural disasters cause major setbacks in economies and to this day these economies are still trying to pick themselves back up. On August 29th, 2005, New Orleans faced a treacherous hurricane called “Katrina”. This natural disaster caused around 25 billion dollars of property damage. If you are including the economic losses, it faced around 100 billion dollar loss! The hurricane was a nightmare for the people and the economy. Thousands of people lost jobs and lost their homes as well. Many companies and businesses were destroyed as a result of Hurricane Katrina. Some of these companies were just being built and as a result, were uninsured. Many of these companies were investments as well, which caused the suffering of the market. There was loss in production due to the destruction of factories as well. The economy sunk to the bottom and left people with nothing. Other states and countries lent their support to New Orleans by putting money into the economy and the government even lowered interest rates. Luckily, the high rise buildings were able to withstand the flooding that occurred after the hurricane. Furthermore, many people looked at the hurricane as a time to rebuild into a better and more efficient economy. The building of more modern structures such as houses, buildings, and factories would increase the wealth of the economy.6 This would take a lot of time and many people today are still suffering from the damages of the hurricane. Global warming was a key factor for the creation of the Hurricane but how? Well, as the temperature increases so does the water and the sea level. Sea levels rise because of the melting of ice due to warmer temperatures and as a result, the oceans become increasingly warmer. When water gets warmer 5 Uzawa, Hirofumi. Economic Theory and Global Warming. Cambridge: Cambridge University, 2003. Web. 6 McMahon, Tim. "Hurricane Katrina:The Economics of Disaster." Www.inflationdata.com. 15 Sept. 2005. Web. <www.inflationdata.com/inflation/Inflation_Articles/Hurricane_Inflation.asp>. Page 6 of 9 it causes it to expand and rise and leads to strong storm. This is the reason hurricanes like Katrina existed. Natural disasters continue to be present in the world and we can confidently say climate change is one of the reasons for that.7 Pandemics have had an effect on global warming. Some diseases are known to spread around a population and can lead to sickness or even death. Some are minor and can be cured by medicine. The diseases that can’t be cured are very infectious and can be disastrous. Global Warming causes climate increases and longer warm conditions, which is why there are more infectious species being able to spread diseases. Princeton university researcher Andrew Dobson said, "Climate change is disrupting natural ecosystems in a way that is making life better for infectious diseases." 8 As global warming continues to happen there will be more people affected by diseases. Mosquitoes exist in warm weather conditions. These insects are known to carry diseases and infect people. With longer warmer conditions they are able to infect more people with diseases such as West Nile. This virus appears in almost all parts of the world and is certainly a threat to our world. From 2002- 2009 there were 42 deaths due to West Nile. In America 4156 people were diagnosed with West Nile and 208 of them died. There is still no vaccine for West Nile and continues to be a threat to our world.9 The death of human beings due to these diseases is horrible and it affects our economy greatly. Just like our natural disasters, pandemics decrease the population which decreases production. When production decreases the economy moves less efficiently. Another economic effect of these pandemics is that they cost money to research. More and more money will be spent on curing the diseases and finding 7 An Inconvenient Truth. Perf. Al Gore. 2006.

That money could be going towards the economy but diseases cannot be ignored and must be treated. The problem is some of these diseases are caused by a result of warming temperatures. Many diseases can be linked to global warming and have and will continue to affect our economy. The effects of natural disasters and pandemics have evidently affected the world’s economies in a negative way. Natural disasters ultimately destroy property and cause the area facing the disaster to be in an economic problem. Pandemics decrease our population and cause our economy to lose money and work less efficiently. Climate change has been an accomplice to these disasters and will continue to have a negative impact on our world’s economies unless we have policies to help prevent the causes of global warming. There are many things people can do to help slow global warming down. If the economy continues to pollute the air then things will not get better. Economic problems will continue to arise and some companies and industries will be affected. Governments should regulate companies and industries by developing more clean energy resources which is basically energy produced by renewable resources. Energy coming from water, wind, and sun will keep the earth more clean and will not contribute to climate change. The United States had 20.7 billion dollars of global clean energy spending in 2009. In 2010, Christopher Martin said, “China’s dominance in clean energy was fueled by a 39 percent increase in investment to a record $54.4 billion last year. That made it the world’s largest manufacturer of wind turbines and solar modules, and helped it overtake the U.S. in terms of installed renewable energy capacity.”10 The United States are unable to sell their cars in China because of environmental concerns. 10 Martin, Christopher.

Page 8 of 9 The more efficient cars are selling like Toyota and Honda rather than GM and Ford. Wind turbines are an example of a clean energy resource. They generate energy and reduce carbon emissions. Solar panels are another example of a clean energy resource. Rather than use wind to generate energy like the wind turbine, it uses the energy from the sun. Both of these resources save you money on your energy bills and prove to be a beneficial investment especially for years to come. In conclusion, climate change has had a negative economic impact on our world’s economies. The biological systems provide resources and a source of income, but these systems have been affected by climate change. Natural disasters and pandemics create huge economic loss and cause a decrease in population. Furthermore, certain actions must be put in place to improve the economies in the world. Otherwise there will be great economic effects that will threaten our world and negatively impact us in the future. It is up to us to make changes and improve the economy. Things will not get better in one day, but it is a process and hopefully individuals will continue with this process that will eventually put the economy in a positive direction. The world has suffered enough economically and changes must be made in order to make life easier, otherwise things will get very ugly. Page 9 of 9 Work Cited An Inconvenient Truth. Perf.
