Read a report you can find here. Basically since 2003 the main areas studied were Alaska, Antarctica, and Greenland - "11 Chesapeake Bays" worth of water has been release thru melting causing a small, but measureable sea-rise. Much of it was sea ice, which does not affect sea levels, but it does affect the oceans ability to reflect solar energy thus causing a warming ocean that affects seasonal ice and air temps... tundra and ocean bottom releases of methane, etc.
Areas north of Alaska were 9 to 10 degrees warmer this year - remember the globe in "An Inconvenient Truth" where the poles warmed much more in proportion to the equator? ... well, it seems to be happening.
"Scientists studying sea ice will announce that parts of the Arctic north of Alaska were 9 to 10 degrees warmer this past fall, a strong early indication of what researchers call the Arctic amplification effect. That's when the Arctic warms faster than predicted, and warming there is accelerating faster than elsewhere on the globe."
