Impacts of a Warming Arctic: Arctic Climate Impact Assessment

The Arctic Climate Impact Assessment (ACIA) is the first comprehensive, integrated assessment of climate change across the entire Arctic region. There are three reports supporting this Assessment:

1) The Scientific Report (2005), is a comprehensive and authoritative scientific synthesis of available information about observed and projected changes in climate and UV radiation and the impacts of those changes on ecosystems and human activities in the Arctic. The synthesis also reviews gaps in knowledge and the research required to fill those gaps. The intended audience is the international scientific community, including researchers and directors of research programs.

2) The Overview Report (2004) for policy makers and the general public, provides observed and projected changes in the physical climate and summarizes the projected impacts to vegetation, species shifts, coastal impacts, marine transportation, thawing ground, indigenous communities, as well as secondary impacts or downstream impacts that will likely occur within each of these areas.

3) The ACIA Policy Document was created to provide policy guidance to the Arctic Council to help guide the individual and collective responses of the Arctic countries to the challenges posed by climate change and UV radiation.

Over 300 scientists contributed to this assessment over a period of five years, as well as other experts and knowledgeable members of the indigenous communities.
