SciGuy: Has the global sea ice decline stopped?
These are good times to be a climate change skeptic.

The planet has not shown substantial warming for a decade now. The Gore Effect seems to be holding. Some glaciers are advancing. And the Arctic Sea ice appears to have halted its decline, if only temporarily.
Arctic Sea Ice News & Analysis
For the past few years, Arctic sea ice extent for most months has been more than two standard deviations below the 1979 to 2000 mean, particularly in summer. Two standard deviations provide an estimate of the expected range of natural variability. Because of cooler than average temperatures, Arctic sea ice extent at the end of April 2009 was within the expected range of natural variability.
