On Feb. 2, 2007, the United Nations scientific panel studying climate change declared that the evidence of a warming trend is "unequivocal," and that human activity has "very likely" been the driving force in that change over the last 50 years. The last report by the group, the Intergovernmental Panel on Climate Change, in 2001, had found that humanity had "likely" played a role.
The greenhouse effect has been part of the earth's workings since its earliest days. Gases like carbon dioxide and methane
allow sunlight to reach the earth, but prevent some of the resulting heat from radiating back out into space. Without the
greenhouse effect, the planet would never have warmed enough to allow life to form. But as ever larger amounts of carbon dioxide
have been released along with the development of industrial economies, the atmosphere has grown warmer at an accelerating
rate: Since 1970, temperatures have gone up at nearly three times the average for the 20th century.
The latest report from the climate panel predicted that the global climate is likely to rise between 3.5 and 8 degrees Fahrenheit if the carbon dioxide concentration in the atmosphere reaches twice the level of 1750. By 2100, sea levels are likely to rise between 7 to 23 inches, it said, and the changes now underway will continue for centuries to come.

This include the publication a famous documentary, The Inconvenient Truth. It shows that the importance of global warming. The objective of establishing this website is to raise the awareness of global warming in our community by educating you a little more about the situation that we are facing today.
