"So much for global warming", is a popular line being sent to our Buzz column this week. But, as data, and the chart above, from the National Center for Atmospheric Research shows, just because record cold snaps keep occurring, doesn't mean that records aren't being made in the other direction as well.
As their senior scientist Gerald Meehl explains, "One of the messages of this study is that you still get cold days. Winter still comes. Even in a much warmer climate, we're setting record low minimum temperatures on a few days each year. But the odds are shifting so there's a much better chance of daily record highs instead of lows."
The report says, "If temperatures were not warming, the number of record daily highs and lows being set each year would be approximately even. Instead, for the period from January 1, 2000, to September 30, 2009, the continental United States set 291,237 record highs and 142,420 record lows, as the country experienced unusually mild winter weather and intense summer heat waves. "
Their report, complete with caveats, can be found here.
