Just because it’s cold outside doesn’t mean there is no global warming…

It’s cold in Florida. Record lows are being hit and there is even a chance of snow in the northern counties. What does this weather pattern say about global warming and climate change?

Nothing. And here’s why.

1. Weather is not climate.  They are two completely different things.  Climate encompasses statistics of  in a region over long periods of time (such as temperature, humidity, atmospheric pressure, wind, rainfall, etc.) Weather, however, is the day-to-day temperature and precipitation.

2. Global warming means less frequent cold snaps (like this current frigidness) and more frequent heat waves. (See April-December in Florida.)

“It’s part of natural variability,” said Gerald Meehl, a senior scientist at the National Center for Atmospheric Research in Boulder, Colo. With global warming, he said, “we’ll still have record cold temperatures. We’ll just have fewer of them.”

Deke Arndt of the National Climatic Data Center in Asheville, N.C., noted that 2009 will rank among the 10 warmest years for Earth since 1880.
