Yes - Polar Ice Sheets Are Melting

CS Monitor: Are polar ice sheets shrinking? Report offers definitive answer at last.

The fuller picture suggests that, collectively, the ice sheets that cover Antarctica and Greenland are now losing three times as much ice each year as they did in the 1990s. All told, they lose about 344 billion tons of ice annually – about in the middle of previous estimates.

These losses push up sea levels about 1 millimeter (0.04 inches) a year.
