Increase in carbon emissions seen tripling since '90s

Emissions of carbon dioxide from fossil fuel burning, the main culprit in
global warming, have increased three times faster in recent years than they did
in the 1990s, international climate researchers reported today.

And human-induced warming may have been responsible for an unprecedented
observation reported Monday by a second group of scientists, who said that for
the first time in 30 years of U.S. satellite monitoring of Antarctica, there is
"clear evidence" of snowmelt on some of the continent's highest and coldest
areas.
