Globally, sea ice is declining, and has been for a while: http://earthobservatory.nasa.gov/IOTD/view.php?id=85246 http://earthobservatory.nasa.gov/IOTD/view.php?id=85246 (That's pulled from the end of the blog post I linked elsewhere.) Quoting directly from what I just linked: Claire Parkinson (http://science.gsfc.nasa.gov/sed/bio/claire.l.parkinson http://science.gsfc.nasa.gov/sed/bio/claire.l.parkinson) has been studying polar sea ice for about four decades. She has been speaking to public audiences for nearly as long. And it was those public audiences who provoked one of the NASA climatologist’s latest research projects. “When I give public lectures or talk with people interested in the topic of polar ice, somebody will often say something like: ‘Well, the ice is decreasing in the Arctic but it’s increasing in the Antarctic, so don’t they cancel out?’” said Parkinson. “The answer is no, they don’t cancel out.”
