Global Warming and Climate Change
(missing works cited)

Global warming and the greenhouse effect are issues discussed by scientists all the time. A natural process that keeps earths temperature at a livable rate is called the greenhouse effect. The energy from the sun warms up the earth when the rays from the sun are absorbed by greenhouse gasses. The gasses then become trapped in the atmosphere. Carbon dioxide, water vapor, methane and nitrous oxide are the most common greenhouse gasses. Greenhouse gases cause the radiant heat of the sun to be trapped in the Earths lower atmosphere which causes global warming. If there weren’t any greenhouse gasses, the earth would be really cold due to very little sun rays being absorbed on the earth. Global warming can and will lead to several problems that affect the environment in which we humans live in. These problems can lead to warmer temperatures all around the world, it can endanger animals and the wildlife, and it can lead to widespread flooding from the glaciers melting. Here are a few more future effects that I will discuss in more detail about. Damage to human health, Severe stress on forests, wetlands, and other natural habitats, how fish will be affected. Global warming is a serious problem that will affect our generation when we are older.

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 from the carbon dioxide. When the oceans and lakes heat up, water is evaporated at a great rate causing more levels of carbon dioxide to be released in our atmosphere. Every time the temperature keeps rising, the more carbon dioxide will be released. When this process gets going, it is very hard to keep in control.

Methane is another greenhouse gas. Methane is a greenhouse gas whose molecules absorb heat trying to escape to space. Natural sources include wetlands, swamps and marshes, termites, and oceans. (Methane) Methane gases...

Natural events and human activities are believed to be contributing to the increase in average global temperatures. This increase is ultimately caused by an increase in ?greenhouse? gases such as Carbon Dioxide (CO2). The global industrial revolution can be linked to the start of this problem for humans. In

Global Warming: Climate Change is Happening Now

1100 words - 4 pages energy is then sent back to the atmosphere as heat. However, greenhouse gases trap that heat, which would otherwise be released into space, raising the temperature of the atmosphere and the Earth's surface. Increases in the amount of greenhouse gases, due to human activities, intensify the heat trapped by the atmosphere and as a result, cause global warming and climate change. Consequently, human behaviors including industrial processes, fossil

The greenhouse effect is the absorption of energy radiated from the Earth's surface by carbon dioxide and other gases in the atmosphere, causing the atmosphere to become warmer. The greenhouse effect is what is

By comparing graphs of the two climatic models, it is apparent that volcanic eruptions cause cooling effects, while pollution aerosols and green house gases causes global warming. The decreasing trend of the models in the second graph, which only includes volcanic aerosols and solar radiation, clearly supports the argument. This means that human caused global warming is the most significant form of climate
