Even as reports emerged showing 2012 could be one of the warmest years on record, NASA images of southwestern Alaska reminded researchers that winter's deep freeze was still imminent.
With winter's official start still a month away, on November 21, NASA's Aqua Satellite and its Moderate Resolution Imaging Spectroradiometer (MODIS) captured this true-color image showing Alaska's Arctic sea ice just beginning to form, turning water off the coast a dull white color.
Gaze closely at the image, and you'll detect only a few areas of tan-colored land and a few green specks of forest peeking through - it appears most rivers are frozen. Arctic ice grows and recedes throughout the year, typically increasing during January and reaching a peak in late February or March.
