Manmade Causes versus Natural Causes The causes of global warming are complex, including natural and man-made emissions of carbon dioxide and methane. Fluorinated gases like hydrofluorocarbons and perluorocarbons are synthetic this means that they are created and emitted solely through human activities. Modelling the climate illustration not visible in this excerpt The first numerical model of the weather was set up by an English mathematician called Lewis Fry Richardson. Arctic sea ice extent in December , for instance, was the ninth lowest in the satellite record. Use your thesis to answer the question of what melting glaciers will mean for populations dependent on the ice flows for their fresh water supply. In the arid American Southwest, for example, average annual temperatures have increased about 1. The global temperature has risen significantly over the last hundred years. This means that it is not easy to stop CO2 emissions because the countries and companies have a strong interest in continuing to do so.

Numerous studies have already reported changes in nature driven by global warming. Geological Survey has tracked the mass of two glaciers in Alaska and one in Washington state, all three of which have shrunk considerably in the past 40 years.

This effect has been beneficial to us in the past because without this capacity to conserve heat, the temperature on Earth would be below the freezing point and making life impossible.

Your thesis may establish the inverse relationship between these rising surface temperatures and the shrinking ice coverage in the Arctic.

Tietenberg T. Largest constributor, as a single nation, are the U. As a result, about 65 percent of the carbon dioxide that human activities have generated since the start of the Industrial Revolution in the early s is in the air we breathe today, as is some that arose from the campfires of Attila the Hun, more than a thousand years before. Use your thesis to answer the question of what melting glaciers will mean for populations dependent on the ice flows for their fresh water supply. Manmade Causes versus Natural Causes The causes of global warming are complex, including natural and man-made emissions of carbon dioxide and methane. As you can see in Figure 2, climate cannot be described in terms of atmosphere alone. The agricultural revolution which supports a human population of 6 billion people and more, depends on the production of fertilizers which is a very energy intensive process. Methane, for example, has an atmospheric lifetime of only about twelve years. Causes of Global Warming Scientists believe that the observed global warming is mainly due to changes in human activities and related increases in greenhouse gas emissions. Focus your thesis on this discrepancy, how man-made carbon dioxide sources, such as fossil fuel consumption, have eclipsed natural sources of the gas.

It threatens the basic elements of life for people around the world. Access to water, food production, health, and use of land and the environment. Moore T. Use your thesis to highlight the difference between natural sources and man-made sources.

Human activities release more than 30 billion tons of carbon dioxide each year, or times as much as volcanoes. It is also removed from the atmosphere when it is absorbed by plants as part of the biological carbon cycle. The global temperature has risen significantly over the last hundred years. In this past century, the temperature rise was faster and lasted longer than any period over the past ten thousend years. Thus, most of the CH4 that our activities add to the air this year, in , will be gone by Will there be more serious disasters and will they be more frequent? The results of a recent study by American researchers suggests that, because of a rapid warming trend over the past decades, the Earth is now reaching, and exceeding, the warmest levels in the current interglacial period, which has lasted nearly 12, years. This effect has been beneficial to us in the past because without this capacity to conserve heat, the temperature on Earth would be below the freezing point and making life impossible. When writing about it, stick to the facts and make sure that your thesis statement -- the central assertion of your essay -- is supported by research. Arctic sea ice extent in December , for instance, was the ninth lowest in the satellite record.
