MTYH: Cold weather, especially unseasonably cold weather, undermines the concept of climate change.

FACTS: "Global warming" is a problematic phrase for a number of reasons, not the least of which is the belief that cold weather somehow invalidates the concept of a global climate crisis. Climate change skeptics are quick to suggest that instances of winter storms (especially when they coincide with activities aimed at addressing "global warming") are evidence that climate change science is flawed.

Rather than exposing climate change as a myth or a mere belief, these skeptics demonstrate the logical fallacy of not seeing the forest for the trees. A recent report by Minnesota's WCCO addresses the problem with using current weather conditions as evidence of broader changes in climate:

"Don't confuse weather with climate," said WCCO's Chief Meteorologist Paul Douglas. "Weather is a snapshot, climate is a long term trend."

In other words, weather is what happens at any given moment in the atmosphere while climate is how the atmosphere behaves over decades and centuries.

Paul said the term global warming can be misleading.

"I think a better description is probably climate change because there are going to be regional variations across the globe," he said.

We need to keep a global perspective in mind because while the United States is experience record cold, some of Europe and Asia are seeing record warmth.

"Don't look out the window and make assumptions about long-term climate," said Paul. "But that goes both ways. In the summertime on the hot humid days we can't beat our chest and say this is global warming."

Grist's Coby Beck made a similar observation last November; RealClimate addresses some of the problems associated with "global warming.". And as happy as I was to see the Rev. Pat Robertson acknowledging climate change last year, we have to note that his recognition was based on the same logical fallacy as those who claim that winter storms in April are valid evidence of problems with climate science.

Our own David Anderson has suggested a new phrase: "global weirding." Given the multiple strange events we're seeing (rapid extinctions of species, shifts in weather patterns, polar ice melts, etc.), it seems appropriate. What other ways can we better communicate the issue of climate change?
