Air temperature

Historical analyses, spatial trends, and changes in extremes

Temperatures in Alaska and the Arctic are rising twice as fast as other parts of the U.S. and—except for sea ice—are the most obvious signs of change. Why? The main reasons are decreases in sea ice and snow cover, warming oceans, and increasing greenhouse gases. Of course, variability exists day-to-day and even year-to-year, depending on average storm tracks, but the trends are unmistakable.

Sea ice

Updates on ice extent, ice thickness, plus historical analyses

Sea ice plays a profound role in the climate, environment, and economies of Alaska. Nothing in the Alaska environment is changing faster than sea ice. Sea ice moderates regional temperatures and moisture, determines the structure of the marine food web, and shapes what people can or can’t do: from subsistence hunting and travel to resource extraction and national security.

Current conditions and longer time period perspectives

Alaska is effectively a very large peninsula. It's surrounded by oceans on three sides, with more than 20% of Alaska land within 25 miles of salt water. As a result, the oceans play an major role in the climate and economies of Alaska: what happens in the oceans does not stay in the oceans.
