Irregular Times Diaries: Unfit Discussion

In the summer of the North, Greenland lost record amounts of ice last year, and the Arctic Ocean’s summer ice cap was reduced to a small size never seen before. Now it’s the summer of the South, and the same activity is being seen in Antarctica, which is losing its ice at a rate almost as fast as Greenland. The rate of ice loss, according to the Jet Propulsion Laboratory, has increased by 75 percent over the last ten years because glaciers are speeding up in their flow to the Antarctic seas. That happens when water from the melting ice lubricates the bottom of the glacier, easing its flow over the ground beneath.

The team’s results do not include data from 2007, the second-warmest year on record. Eric Rignot, who led the study, comments, “Ice sheets are responding faster to climate warming than anticipated.”
