EPA Climate Change - According to the National Academy of
Sciences, the Earth's surface temperature has risen by about 1
degree Fahrenheit in the past century, with accelerated
warming during the past two decades. There is new and stronger
evidence that most of the warming over the last 50 years is
attributable to human activities. Human activities have
altered the chemical composition of the atmosphere through the
buildup of greenhouse gases – primarily carbon dioxide,
methane, and nitrous oxide. The heat-trapping property of
these gases is undisputed although
uncertainties
exist about exactly how earth's climate responds to them. Go
to the
Emissions
section for much more on
greenhouse gases. |
