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 "verylikely" 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 addition of that single word "very" did more than reflect mounting scientific evidence that thereleaseof carbon dioxide and otherheat-trappinggases fromsmokestacks,tailpipesand burning forests has played a central role in raising theaveragesurface temperature of the earth by more than 1 degree Fahrenheit since 1900. It also added new momentum to adebatethat now seems centered less over whether humans are warming the planet, but instead over what to do about it. In recent months, business groups havebandedtogether to makeunprecedentedcalls for federal regulation of greenhouse gases. The subject had a red-carpet moment when former Vice President Al Gore's documentary, "An Inconvenient Truth," was awarded an Oscar; and the Supreme Court made its first global warming-related decision, ruling 5 to 4 that the Environmental Protection Agency had notjustifiedits position that it was not authorized to regulate carbon dioxide.
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 anacceleratingrate: Since 1970, temperatures havegone upat 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 reachestwicethe 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.

"Whether it‛s recycling, walking your children to school instead of driving or fullyinsulatingyour home to reduce the energy required to heat it, it all helps." Michael Fish, May 2006
