Satellite photos show Lake Superior nearly iced-over on March 3, 2009.
Reportedly, this phenomenon happens about every 20-30 years. Another source reports that global floating sea ice levels this year are as high as they were in 1979, using data and a chart from the University of Illinois’ Arctic Climate Research Center:
Rapid growth spurt leaves amount of ice at levels seen 29 years ago.
Thanks to a rapid rebound in recent months, global sea ice levels now equal those seen 29 years ago, when the year 1979 also drew to a close.
Ice levels had been tracking lower throughout much of 2008, but rapidly recovered in the last quarter. In fact, the rate of increase from September onward is the fastest rate of change on record, either upwards or downwards.
The data is being reported by the University of Illinois’s Arctic Climate Research Center, and is derived from satellite observations of the Northern and Southern hemisphere polar regions.
“Thanks to a rapid rebound in recent months.” You’ve got to give President Obama credit; he said he’d stop global warming and he has!
