Reports Point to Proof of Global Warming

Politicians in the nation's capital have been reluctant to set limits on the carbon dioxide pollution that is expected to warm the planet by 4 to 7 degrees Fahrenheit during the next century, citing uncertainty about the severity of the threat. But that uncertainty may have shrunk somewhat with the release last week of two scientific reports suggesting that global warming is not just a hypothetical possibility, but a real phenomenon that has already started transforming especially sensitive parts of the globe.
Overall, the reports say, Earth's climate has warmed by about 1 degree Fahrenheit since 1900. In the Arctic, where a number of processes amplify the warming effects of carbon dioxide, most regions have experienced a temperature rise of 4 to 7 degrees in the last 50 years.
That warmth has reduced the amount of snow that falls every winter, melted away mountain glaciers and shrunk the Arctic Ocean's summer sea ice cover to its smallest extent in millennia, according to satellite measurements. Swaths of Alaskan permafrost are thawing into soggy bogs, and trees are moving northward at the expense of the tundra that rings the Arctic Ocean.
