Despite East Coast freeze, global warming is for real

No single weather event can be directly attributed to climate change. But as the globe warms up, Americans can expect more storms like the one bearing down on much of the United States, scientists say.

That's not because the Feb. 1 storm can be linked to rising atmospheric carbon dioxide levels or increasing global temperature – again, such a connection is impossible to make – but, according to climatologists, an increased propensity for winter storms is exactly what you'd expect in a warming world.

"There's no inconsistency at all," Michael Mann, the director of the Penn State Earth System Science Center, told LiveScience. "If anything, this is what the models project: that we see more of these very large snowfalls."
