Changes in summer Arctic wind patterns contribute not only to an unprecedented loss of Arctic sea ice, but could also bring about shifts in North American and European weather, according to a new...

An international team of scientists who monitor the rapid changes in the Earth’s northern polar region say that the Arctic is entering a new state - one with warmer air and water temperatures,...

Arctic Report Card: 2011

The annual Report Card provides clear, concise scientific information on the state of the Arctic region, organized into 5 sections: Atmosphere, Sea Ice & Ocean, Marine Ecosystems, Terrestrial Ecosystems, and Hydrology & Terrestrial Cryosphere.  This edition was prepared by an international team of 121 scientists from 14 different countries.  Independent peer-review of the 2011 Report Card was organized by the Arctic Monitoring and Assessment Programme of the Arctic Council.

NOAA explained today how it will concentrate scientific, service, and stewardship efforts in the Arctic when it released its first ever Arctic Vision and Strategy. Jane Lubchenco, Ph.D., under...

It’s a puzzle: How could warmth in the Arctic produce frigid conditions elsewhere? NOAA scientists may have a clue.

The Arctic region, also called the "planet’s refrigerator," continues to heat up, affecting local populations and ecosystems as well as weather patterns in the most populated parts of the Northern...

Sea Ice Manual

The purpose of the Alaska Center for Climate Assessment and Policy's Sea Ice Manual is to improve the availability of current information about sea ice from operational and academic observation programs to key user groups. It provides Arctic Alaska coastal community leaders and local user groups with an up-to-date, comprehensive, and practical guide to current reference resources on sea ice and climate that are relevant to their planning, subsistence activities, and way of life.

Past Climate Variability and Change in the Arctic and at High Latitudes

Over the past 30 years, average temperatures in the Arctic have increased at almost twice the rate of the planet as a whole. Such temperature changes have been accompanied by shrinking sea ice, melting ice and permafrost on land, and widespread impacts to land and ocean ecosystems.

Arctic Climate Impact Assessment

An international project of the Arctic Council and the International Arctic Science Committee, the Arctic Climate Impact Assessment evaluates and synthesizes knowledge on climate variability, climate change, and increased ultraviolet radiation and their consequences for the Arctic region.
