As the world heats up

IN ANTARCTICA: Lonnie Thompson
Fine feature for the season today in the New York Times.

It's the detailed story of Lonnie Thompson, a climate scientist. What does he know that Rush Limbaugh and similar climate change deniers don't know? That tropical ice caps are melting in an unprecedented way, based on his study of ancient ice.

Dr. Thompson became one of the first scientists to witness and record a broad global melting of land ice. And his ice cores proved that this sudden, coordinated melting had no parallel, at least not in the last several thousand years.

To some climate scientists, the Thompson ice core record became the most convincing piece of evidence that the rapid planetary warming now going on was a result of a rise in greenhouse gases caused by human activity.

Quibble with the science at will. But enjoy the ice-encrusted photos.
