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.
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
January 1, 2009
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.
