Scientists Alarmed By Global Warming

But they warn that in future this protection will lessen due to controls on pollution. Their best guess is that, as the mask is removed, temperatures will warm by at least 6°C by 2100. That is substantially above the current predictions of 1.5 to 4.5°C. "Such an enormous increase would be comparable to the temperature change from the previous ice age to the present," says one of the researchers, Meinrat Andreae of the Max Planck Institute for Chemistry in Mainz, Germany. "It is so far outside the range covered by our experience and scientific understanding that we cannot with any confidence predict the consequences for the Earth." http://www.newscientist.com/article.ns?id=dn7964 http://www.newscientist.com/article.ns?id=dn7607 [Proofreader's note: this article was edited for spelling and typos on September 12, 2005]
