A recent letter to the editor (TNT, 9-11) suggested that a 60 percent increase in the Arctic ice pack from August 2013 to August 2012 should have been published by The News Tribune as climate news – presumably to offer evidence against global warming or climate change. The author implies that the TNT has a liberal agenda.
Perhaps, but that doesn’t change facts surrounding climate change. Peer-reviewed data show that climate change is real, and a vast majority of scientists accept the overwhelming evidence
The increase in the Arctic extent (coverage area of the ice pack) is not, by itself, evidence of global cooling. The extent has been shrinking at almost 11 percent per decade since 1978. August 2012 was the lowest Arctic extent measurement ever taken, and the increase this year barely made it above the downward sloping trend line.
In any given year, the Arctic extent may have increased, but the trend has been on a down slope. Even more troubling is the fact that the thickness of the ice pack has been shrinking rapidly over the last three years. I suspect the trend will continue.
As Paul Harvey used to say, now you know the rest of the story.
