WASHINGTON  As millions of people along the East Coast hole up in their snowbound homes, the two sides in the climate-change debate are seizing on the mounting drifts to bolster their arguments.

Skeptics of global warming are using the record-setting snows to mock those who warn of dangerous human-driven climate change  this looks more like global cooling, they taunt.

Most climate scientists respond that the ferocious storms are consistent with forecasts that a heating planet will produce more frequent and more intense weather events.

But some independent climate experts say the blizzards in the Northeast no more prove that the planet is cooling than the lack of snow in Vancouver or the downpours in Southern California prove that it is warming.
