THE POLAR CAPS ARE MELTING

Wrong. The British Antarctic Survey, working with NASA, last week confirmed ice around Antarctica has grown 100,000 sq km each decade for the past 30 years.

Long-term monitoring by the US National Oceanic and Atmospheric Administration reports the same: southern hemisphere ice has been expanding for decades.

As for the Arctic, wrong again.

The Arctic ice cap shrank badly two summers ago after years of steady decline, but has since largely recovered. Satellite data from NASA's Marshall Space Flight Centre this week shows the Arctic hasn't had this much April ice for at least seven years.

Norway's Nansen Environmental and Remote Sensing Centre says the ice is now within the standard deviation range for 1979 to 2007.
