Winter storms don't debunk global warming

Here on Smith Island in the Chesapeake Bay we have recently experienced three storms with blizzard conditions in just two weeks. Much of the rest of the mid-Atlantic area of the United States has seen similar situations, and some areas have accumulated up to 6 feet of snow this winter.

Avoid solutions worse than the problem

Any risks of global warming need to be weighed against the risks of global warming policies. Policymakers must have accurate information on both sides of the equation in order to avoid measures that do more harm than good.

Reassess scientific knowledge

Attempting to use the recent snows to bolster assertions that either confirms or undermines the notion of human-caused global warming adds more confusion to the debate and misdirects where we should focus our attention. No small number of weather events are sufficient to draw a conclusion about human influence on the climate system

Missteps and moisture

Unfortunately, the news media seem more focused on controversy than on substance, contributing to the rampant confusion about "global weirding," as Tom Friedman calls it.
