Alaska has warmed twice as fast as the rest of the U.S. over the past several decades. All climate models agree that temperatures are projected to increase over the 21st century across Alaska, with larger increases projected for later in the century. The greatest warming is expected in northern Alaska, with less warming projected for the southeast part of the state. The greatest warming is expected during winter months, with less dramatic increases expected during the summer. The immense size of Alaska, combined with complexities of topography, sea-ice dynamics, and ocean currents makes it necessary to rely on downscaled climate data to estimate future changes for particular locations.
