climate change alaska
Observed Climate Change. Over the past 60 years, Alaska has warmed more than twice as rapidly as the rest of the United States, with state-wide average annual air temperature increasing by 3Â°F and average winter temperature by 6Â°F, with substantial year-to-year and regional variability.
Projected Climate Change. Average annual temperatures in Alaska are projected to rise by an additional 2Â°F to 4Â°F by 2050. If global emissions continue to increase during this century, temperatures can be expected to rise 10Â°F to 12Â°F in the north, 8Â°F to 10Â°F in the interior, and 6Â°F to 8Â°F in the rest of the state.
