Global warming is a great treat for our planet and its nature. It gradually wipes out everything which exists on the earth’s surface. In recent years, global warming and climate change have become one of the biggest topics, which rise concerns among people. Global warming is an increase in average surface temperature of the earth. It has several negative impacts on the environment and on its inhabitants. Many factors can cause global warming, but the significant one is greenhouse gases. Greenhouse gases have negative effects on climate and cause melting of polar ice caps, acid rain, and ozone layer destruction.
The significant effect of global warming is emission of greenhouse gases, which has numerous negative environmental impacts. Fossil fuels are known as a big cause of global warming. When fossil fuels such as: natural gas, coal, and oil are burned, they release carbon dioxide, sulfur dioxide, and nitrogen dioxide to the air. However, most of our energy sources come from fossil fuels, which are the main contributors to air pollution and global warming. For instance, one of the major sources of air pollution is emission of chemical gases by industries. According to the Environmental Protection Agency (EPA), “it has been found that 50 percent of the pollution in the United States has been made by industrial processes”.
Due to release of heat trapping gases in the air, the temperature of the atmosphere increases, this causes sudden flooding and high tides. Polluted air contains high levels of carbon dioxide and other dangerous chemical gases. When these pollutants are released, they trap the heat in the atmosphere and hotter weather results. Therefore, the warmer temperature causes melting of polar ice caps which is very damagi...

... rain, which damages woods and forests. Furthermore, the emission of greenhouse gases causes holes in the ozone layer, which can cause diseases especially skin problems in humans. It is our responsibility to save this planet from being destroyed, and we can fight global warming by planting more trees to reduce the amount of existing carbon dioxide in the air.

What is global warming? According to the Natural Resource Defense Council, “Carbon dioxide and other air pollution that is collecting in the atmosphere like a thickening blanket, trapping the sun’s heat and causing the planet to warm up” (“Natural Resources Defense Council”). This shows that global warming is caused due to the fact that harmful gases such as Carbon Dioxide escape into the atmosphere and capture all of the sun’s heat; keeping it secure. This causes the planet to get warm. Coal burning power plants are the main cause of global warming (Natural Resources Defense Council). Power plants and factories give off gases that pollute the air and cause disruptions in the atmosphere. These gases taint the atmosphere, making it thicker and causing it to contain more heat, also warming the earth. These intense heating conditions lead to w...
One of the biggest environmental impacts which is steadily increasing in severity due to fossil fuel usage is global warming. Global warming is mainly caused due to the trapping of heat in the atmosphere due to increased amounts of carbon dioxide. Because of the burning of fossil fuels, there has been a twenty five percent increase in the amount of carbon dioxide in the atmosphere over the last 150 years (Clean Energy). This increase over the years has caused the global average surface temperature to raise ...
In addition to reducing the gases we emit to the atmosphere, we can also increase the amount of gases we take out of the atmosphere. Plants and trees absorb CO2 as they grow, "sequestering" carbon naturally. Increasing forestlands and making changes to the way we farm could increase the amount of carbon we're storing. The alarming world’s climate is very dangerous for mankind and ecological balance. Unless Global Warming is not controlled, no men, animals will be able to live, grow and thrive. So, we should try maintain the ecological balance to decrease the effects of Global Warming.
The greenhouse effect is a natural process that keeps the earth at temperatures that are livable. Energy from the sun warms the earth when its heat rays are absorbed by greenhouse gasses and become trapped in the atmosphere. Some of the most common greenhouse gasses are water vapor, carbon dioxide, and methane. If there were no greenhouse gasses, very few rays would be absorbed and the earth would be extremely cold. When too many rays are absorbed the earth’s atmosphere heats up and it causes what we know as global warming. Al Gore (2006) described the greenhouse effect as the potentially most dangerous environmental problem facing mankind, with consequences second only to nuclear war (p.299). As the name suggests, global warming isn’t merely affecting parts of the world, it is threatening the world globally.
Global Warming, much of what does or does not happen forty years from now rests on our actions or inactions taken between now and then. The crucial question is whether we should pour all our resources into mitigation – reducing our carbon emissions. According to scientists who study the climate there are other environmental problems; “we now face a global crises in land use and agriculture that could undermine the health, security, and sustainability of our civilization”.
When people burn fossil fuels to accumulate and produce energy a substance called carbon is produced. Carbon is released into the air in a form known as carbon dioxide. Carbon moves throughout the biosphere on the planet as it is recycled and reused. Carbon exists in the earth’s atmosphere in two common forms which are methane and carbon monoxide. These gases absorb and retain heat in a process known as the greenhouse effect. The Planets natural greenhouse effect makes life possible by regulating our temperature. It turns out that adding too much to the greenhouse effect can have horrible consequences on the environment. Each year, five and a half billion tons of carbon is released by burning fossil fuels and of that three billion tons enters the atmosphere. The remaining carbon usually gets absorbed by the oceans.
Human induced climate change resulting from an enhanced greenhouse effect is probably the greatest environmental threat facing the world today. Specifically, the emission of greenhouse gases such as carbon dioxide may be classified as the primary culprit. As a result of greenhouse gases entering the upper levels of the earth's atmosphere, it diminishes or breaks down the earth's Ozone layer. With this loss of this protective blanket, harmful radioactive rays from the sun enter the deeper into the earth's atmosphere. This creates a rise in the overall temperature of our planet, along with alterations in the global environment, ecosystems and way of life for the habitants of earth.
Global Warming has occurred in the distant past as the result of natural influences. Now the warming predicted to occur is a result of increased emissions of greenhouse gases. Greenhouse gases include water vapor, carbon dioxide, methane, nitrous oxide, and ozone. (Scientists, 2010) Carbon dioxide is a very important factor in the cycle that sustains life on Earth, Plants use carbon dioxide in photosynthesis and release oxygen that’s is necessary to maintain the lives of humans and animals, who exhale carbon dioxide into the atmosphere, completing the cycle (Cunningham & Cunningham, 2009) .
Global warming and global climate change is the study of future increases of temperature across the globe. Studying climate change refers to how the over- all climate will change such as the dry places getting dryer and the wet places getting wetter. Global climate is dependent on “the greenhouse effect a natural process that helps regulate temperature” (Easterling and Karl). In the past few centuries humans have had a monumental effect on increasing of greenhouse gases in the atmosphere. Climate change is result of the increase amount of the greenhouse gasses in the atmosphere such as methane, carbon dioxide, water vapor, nitrous oxide, and ozone. “Global temperature has rose approximately 1.4 degrees Fahrenheit over
Carbon Dioxide, methane and nitrous oxide make up the biggest part of the cause of global warming, which form greenhouse gases. Greenhouse gases are trapped in the earth’s atmosphere and cause the earth to warm up. This temperature change has an effect on the earth’s ice, glaciers, oceans and ecosystems.
Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth's climate. While it changes the Earth’s climate it takes away different species that we depend on and some which other species depend on and also effect (in a bad way) the environment in which we live and can cause permanent damages to humans, animals, plant which will change the whole chain of ecosystem.
In talking about global warming, we need to learn what causes the greenhouse effect. Rays from the sun are taken up and absorbed by water vapor that is natural in the atmosphere. The United States emits the largest man made greenhouse gases in the world. As Americans we must realize the responsibility to reduce the emissions. (Gore, Albert) Water Vapor is eighty percent of greenhouse warming. The last twenty percent results from other gases that are in very little amounts. A huge absorber of the sun’s heat rays is carbon dioxide. Us as humans release a lot of carbon dioxide. When fossil fuels are burned, they release big amounts of carbon dioxide. Carbon dioxide is on the increase in our atmosphere due to car emissions. Approximately eighty percent of CO2 increases because of man’s use of fossil fuels. When there is more carbon dioxide in our atmosphere the more sun rays are absorbed. In result to this happening this will cause the earth and the earths atmosphere to warm. When the earth is warming, water temperatures will start to get warmer. Oceans and lakes will get warmer in result f...
One of the major issues in today’s society is Global warming. It is one of many kinds of climate that the Earth goes through. The primary cause of global warming is the human expansion of the greenhouse effect. Greenhouse gases keep the earth warm through a process called greenhouse effect. Greenhouse gases like Carbon dioxide trap heat from the atmosphere and maintain the soil warm. Without greenhouse gases, our planet would be too cold. However, people are adding extra greenhouse gases when they’re driving, using electricity, and in a factory. A lot of energy comes from fossil fuels. According to Environmental Protection Agency, the earth’s temperature has increased by 0.8 degree Celsius over the past century. More than half of this grew
Global warming is also called as climate change, when temperature rise more than usual. Earth is getting hotter, temperature in arctic is decreasing and many animals` habitats are disappearing. The results from the effects of global warming is called greenhouse effect. CO2, Methane, Water vapor, nitrous oxide, and ozone are the examples of green house gases. The greenhouse gases is to allow heat to enter the enclosure easily but it doesn`t let the radiation to go back to atmosphere. The ray that enters the atmosphere`s wavelength is short and when it enters, the greenhouse gases take heat from these rays and it increases the temperature. Also the heat will be unable to go out the atmosphere because infrared rays have longer wavelength. Power plant is the major reason of carbon dioxide emission. The plants work by burning fossil fuels and it produces large amount of Carbon Dioxide. Also, Vehicles is one of the causes of global warming. In addition, deforestation is also a cause of global warming. Trees can take in CO2 from atmosphere and it releases oxygen. Moreover, Increase in Sea level is also a reason. Earth is warming so ice is melting and it increases the water levels. However the ice caps are made of freshwater and if it mixes with ocean the eco system be imbalance. Also when ice caps will make sea to expose to the sun and this will make earth hot (Global Warming and Carbon
What is global warming? Global warming is defined as a gradual increase in the overall temperature of the earth’s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants. This issue is not only a concern to the United States, but to the entire world because everyone and everything is being affected due to global warming. This problem is a big concern because not only is it effecting the Earth, but humans as well. Global warming affects the environment, the climate, animals, and humans all together. Sadly this problem is a concern to many and a joke to others, and without the help of everyone this issue can have a dramatic change in the lives of many.
