A recent article published by Forbes by Heartland Institute Senior Fellow James M. Taylor has been causing quite a stir. The article titled “Updated NASA Data: Global Warming Not Causing Any Polar Ice Retreat,” highlights the fact that global warming is not causing arctic melting that so many alarmists fear.
Expanding polar ice caps are defying alarmist global warming claims, sending global warming alarmists into desperate damage control. Since late 2012, polar ice extent has averaged greater than the long term mean. When I pointed this out in a recent Forbes.com column, and after more than a quarter million people learned the truth by reading my column, the alarmists predictably began searching for ways to spin the expanding polar ice. Fortunately, the truth will always win out over scientifically unsupported spin and fearmongering.
Updated data from NASA satellite instruments reveal the Earth’s polar ice caps have not receded at all since the satellite instruments began measuring the ice caps in 1979. Since the end of 2012, moreover, total polar ice extent has largely remained above the post-1979 average. The updated data contradict one of the most frequently asserted global warming claims – that global warming is causing the polar ice caps to recede.
The melting of glaciers is often cited as evidence mankind is causing global warming through carbon dioxide emissions. A corollary of this is that melting glaciers raise sea levels, which will reach catastrophic levels unless CO2 emissions are reduced. Adding to the massive evidence already refuting these assertions, a recent paper provides more accurate reconstruction of two centuries of previous data “by using many more stations, particularly in the polar regions, and recently processed historic data series from isolated island stations.”
If anyone could rationally be labeled climate change deniers, it is those who hold the absurd view that our climate was relatively tranquil until the arrival of humans. They seem to not know that half of North America was under a vast ice sheet only 22,000 years ago. And, as Patterson has written, “Ten thousand years ago… temperatures rose as much as 6 degrees Celsius in a decade — 100 times faster than the past century’s 0.6 degrees Celsius warming.”
