Global Warming Is Not the Cause of Polar Ice Cap Retreat

Published February 5, 2008

Global warming is not causing any significant retreat of polar ice caps, despite claims to the contrary in some media reports, says James M. Taylor, senior fellow for environment policy at The Heartland Institute.

Although Arctic sea ice last summer reached its minimum extent since satellites began measuring the ice in 1979, NASA scientists have discovered the sea ice retreated due to variable local wind patterns rather than global warming. Moreover, the ice re-formed at a record pace last fall.

In the Southern Hemisphere, Antarctic sea ice is at its greatest extent in recorded history. The majority of Antarctica is in a prolonged cold spell and has been accumulating snow and ice for decades.
