There continues to be widespread and, in some cases, dramatic evidence of an overall warming of the Arctic system.
Atmosphere: 5° C temperature increases were recorded in autumn
Ocean: Observed increase in temperature of surface and deep ocean layers
Sea Ice: Near-record minimum summer sea ice extent
Greenland: Records set in both duration and extent of summer surface melt
Biology: Fisheries and marine mammals impacted by loss of sea ice
Land: Permafrost temperatures tend to increase, while snow extent tends to decrease The Arctic Report Card is introduced as a means of presenting clear, reliable and concise information on recent observations of environmental conditions in the Arctic, relative to historical time series records. Issued annually, it provides a method of updating and expanding the content of the State of the Arctic Report, published in fall 2006, to reflect current conditions. Some of the essays are based upon articles in the BAMS State of the Climate in 2007.
Material presented in the Report Card is prepared by an international team of scientists and is peer-reviewed by topical experts of the Climate Experts Group (AMAP) of the Arctic Council. The audience for the Arctic Report Card is wide, including scientists, students, teachers, decision makers and the general public interested in Arctic environment and science. The web-based format will facilitate future timely updates of the content.
