If the Arctic is a doctor’s patient, the National Oceanic and Atmospheric Administration’s (NOAA) Arctic Report Card is its annual physical – a comprehensive check-up on the health of this vast and important biome.
Today’s Arctic is much hotter, greener and less icy than it was even just 15 years ago, when NOAA published its first Arctic Report Card.

“But the rate of change we’ve seen in the last 20 years – and especially the last five years – is beyond what we thought would happen”.
