Global warming essay does carbon dioxide make the air warmer
What Is Deforestation and Global Warming Free Essay Example
I heard that carbon dioxide makes up 0. Not 0. I am often asked how carbon dioxide can have an important effect on global climate when its concentration is so small — just 0. I study the importance of atmospheric gases for air pollution and climate change. Working separately, John Tyndall in England and Eunice Foote in the United States found that carbon dioxide, water vapor and methane all absorbed heat, while more abundant gases did not. Scientists had already calculated that the Earth was about 59 degrees Fahrenheit 33 degrees Celsius warmer than it should be , given the amount of sunlight reaching its surface. The best explanation for that discrepancy was that the atmosphere retained heat to warm the planet.
The issue can be overwhelming. The science is complicated. Predictions about the fate of the planet carry endless caveats and asterisks. This should give you a running start on understanding the problem. As of early , the Earth had warmed by roughly 2 degrees Fahrenheit, or more than 1 degree Celsius, since , when records began at a global scale.
Ash spews from a coal-fueled power plant in New Johnsonville, Tennessee. Though this warming trend has been going on for a long time, its pace has significantly increased in the last hundred years due to the burning of fossil fuels. As the human population has increased, so has the volume of fossil fuels burned. Gases produced by the burning of fossil fuels prevent the heat from leaving the atmosphere.
