Issued annually since 2006, the Arctic Report Card 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 rapid pace and complexity of Arctic change demand new and strengthened Arctic adaptation and global reductions of fossil fuel pollution. The Arctic continues to warm at a faster rate than the global average. The 2024 Arctic Report Card highlights record-breaking and near-record-breaking observations that demonstrate dramatic change, including Arctic tundra transformation from carbon sink to carbon source, declines of previously large inland caribou herds, and increasing winter precipitation. Observations also reveal regional differences that make local and regional experiences of environmental change highly variable for people, plants and animals. Adaptation is increasingly necessary and Indigenous Knowledge and community-led research programs are essential to understand and respond to rapid Arctic changes.
