Alaska: Observed and Projected Temperature Rise

Alaska: Observed and Projected Temperature Rise

Alaska’s annual average temperature has increased 3.4ºF over the past 50 years. The observed increase shown above compares the average temperature of 1993-2007 with a 1960s-1970s baseline, an increase of over 2ºF. The brackets on the thermometers represent the likely range of model projections, though lower or higher outcomes are possible. By the end of this century, the average temperature is projected to rise by 5 to 13ºF above the 1960s-1970s baseline. Image Reference: CMIP3-A1
