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, policy-makers, and the general public interested in the Arctic environment and science.
