Annual average near-surface air temperatures across Alaska and the Arctic have increased over the last 50 years at a rate more than twice as fast as the global average temperature ( very high confidence ).

Rising Alaskan permafrost temperatures are causing permafrost to thaw and become more discontinuous; this process releases additional carbon dioxide and methane , resulting in an amplifying feedback and additional warming ( high confidence ). The overall magnitude of the permafrost–carbon feedback is uncertain; however, it is clear that these emissions have the potential to compromise the ability to limit global temperature increases.

It is very likely that human activities have contributed to observed arctic surface temperature warming, sea ice loss, glacier mass loss, and Northern Hemisphere snow extent decline ( high confidence ).

The sheer wildness of Alaska is unmatched by any state, leaving most visitors to this land no less than awestruck.  Soaring mountain ranges, rushing rivers and Arctic tundra provide critical habitat for salmon, polar bears, caribou, black and grizzly bears, whales, walruses, migratory birds and many other species. They also are home to Alaska’s indigenous people, who depend on wildlands as a source of food and clean water.

Alaska is America’s last great, wild frontier. In Alaska you can still see caribou migrating through vast valleys, salmon streams running through ancient forests and polar bears roaming icy shores of the Arctic Ocean.

From the Tongass National Forest in the south to the Arctic coastal plain in the north, Alaska is full of inspiration, as the locals will tell you.

Scientists blog from Antarctica and provide a glimpse of what it's like to do research in the field. Read their blog ...

When scientists talk about the cryosphere, they mean the places on Earth where water is in its solid form, frozen into ice or snow. Read more ...

Arctic sea ice extent in December 2017 was below average in both the far northern Atlantic and the Bering Sea, and notably high temperatures prevailed over most of the Arctic, especially over Central Alaska. We look back at the year’s events, and examine Arctic sea ice trends since 1850 based on a new compilation of data from maps, ship reports, and other records.

Arctic Wild provides professionally guided Alaska adventure tours in Alaska’s vast wilderness. Trust your Alaskan adventure vacation to an experienced Arctic Wild Guide.

Groups are small (1 to 8 people), we travel quietly, and the focus is on the land and its inhabitants. Whether you join us for a base camp trip, river rafting, canoeing or backpacking adventure there is plenty of free time for you to explore, bird watch, photograph, fish or do whatever pleases you most.

Arctic Wild has the perfect Alaskan Adventure for you. Choose from canoeing in Gates of the Arctic National Park , or photographing caribou in the Arctic National Wildlife Refuge . Experience a backpacking trip in the remote Western Brooks Range , or try a rafting trip on the Kongakut River .
