A Thawing Archive
Polar tundra, glaciers and permafrost are changing faster than any other biome — and the atlas is watching the transition pixel by pixel.
The fastest-changing place on Earth
The Arctic is warming nearly four times faster than the global average. Tundra that has been frozen since the last glacial maximum is greening, and the ice that defines the region is in retreat.
Svalbard and the mainland
Norway’s marine boundary reaches from temperate fjords to the high Arctic. Within one country the atlas spans coastal woodland, alpine cryogenic systems and permanent ice.
Ice, isolated
Filtering to ice sheets, glaciers and perennial snowfields turns the map into a thermometer: every pixel here is a surface that either persists or does not, and the boundary moves each summer.
A baseline worth having
You cannot measure retreat without a starting line. Consistent global classification gives the Arctic something it has rarely had: one map, one method, repeated.
