About Arctic Report Card 2018

The Arctic Report Card (hereafter ‘ARC’) has been issued annually since 2006. It is a timely and peer-reviewed source for clear, reliable, and concise environmental information on the current state of different components of the Arctic environmental system relative to historical records. The ARC is intended for a wide audience, including scientists, teachers, students, decision-makers, and the general public interested in the Arctic environment and science.

ARC 2018 contains 14 contributions (we call them essays) prepared by an international team of 81 researchers from 12 different countries. As in previous years, independent peer review of ARC 2018 was organized by the Arctic Monitoring and Assessment Programme (AMAP) of the Arctic Council.

ARC 2018 is organized into three sections: Vital Signs, Other Indicators, and Frostbites. The Vital Signs section is for annual updates on the same seven topics: Surface Air Temperature; Terrestrial Snow Cover; Greenland Ice Sheet; Sea Ice; Sea Surface Temperature; Arctic Ocean Primary Productivity; and Tundra Greenness. The Other Indicators section is for topics that will be updated every 2-4 years, many of which have appeared in previous ARCs (e.g., Lake Ice, River Discharge, Reindeer and Caribou, Permafrost, to name a few). The Frostbites section is for reports on new and newsworthy items, describing emerging issues, and addressing topics that relate to long-term scientific observations in the Arctic.

People occasionally ask questions such as “How are essay topics selected?” or “Why is topic X not in the Arctic Report Card?” The short answer is that each ARC strives to include some recurrent topics as well as new topics, and thus cover many topics over a period of years. In this way the ARC can achieve a comprehensiveness over time that is not possible given the severe time constraints in its production schedule. A complete list of topics covered since the first publication of the ARC is available at Previous Report Cards.

Financial support for Arctic Report Card 2018 was provided by the Arctic Research Program in the NOAA Climate Program Office, including content editing via the Cooperative Institute for Alaska Research with funds from the NOAA Administration under cooperative agreement NA13OAR4320056 with the University of Alaska. In kind support was provided by the Office of Naval Research and the Cold Regions Research and Engineering Laboratory of the Engineer Research and Development Center, U.S. Army Corps of Engineers. The editors thank AMAP for organizing the independent peer review and those who provided review comments.
