Hundreds of cities across most of the eastern United States suffered record cold and snow throughout much of April.  Analysts point out the unexpected cold spell illustrates the unpredictability of both weather and longer-term climate conditions, says John Dale Dunn, member of the Science and Policy Advisory Board of the American Council on Science and Health.


  • Easter morning, April 8, saw record lows for much of the Southeast and Midwest and an unseasonably cold weekend for much of the Northeast; snow extended from the Upper Midwest to New England.
  • In Chicago, the high temperature in the city reached just 32 degrees on Saturday, April 7, matching a record set in 1936 for lowest high temperature on the date.
  • In South Carolina, 90 percent of the peach crop was destroyed in a mid-April deep freeze.
  • In Kentucky, Agriculture Commissioner Richie Farmer asked Gov. Ernie Fletcher (R) to seek federal disaster relief as a result of the prolonged blasts of Arctic air; Fletcher reported as much as 90 percent of the state's apple and peach crops were destroyed.

"This shows how little we know about short-term weather events, let alone long-term events," said Sterling Burnett, a senior fellow with the National Center for Policy Analysis.  "When the news media and the global warming alarmists attempt to attribute every short-term heat spell to global warming, then the protracted winter conditions this spring must be evidence of global cooling, according to their hypothesis.

"Of course, neither is truly the case," Burnett explained.  "There is extreme variability to short-term weather events, and even to decades-long climate patterns.  Not every heat wave or cold spell can be cited as proof of any asserted long-term trends."
