Since 1979, the Arctic has been warming more than three times faster than the global average, and the latest evidence shows its ecosystems are now reshaping the global climate system itself.
Today we're sharing a major new compilation from AMAP and Conservation of Arctic Flora and Fauna Working Groups of the Arctic Council: 11 peer-reviewed reviews and an editorial synthesis, published as a Special Issue in Frontiers in Environmental Science, with contributions from 113 scientists across the Arctic research community.
A few headline findings:
• In the Arctic Ocean, net primary production rose 57% between 1998 and 2018, and sea-ice loss is fuelling marine heatwaves, shifting species northward ("borealization"), and disrupting food webs that Indigenous and coastal communities depend on.
• On land, the tundra has gradually become greener over the past 40 years, yet thawing permafrost, shifting hydrology, and intensifying wildland fires (the unprecedented 2023 wildland fire season was the first summer global temperatures exceeded +1.5°C above pre-industrial levels), are changing the carbon balance of these landscapes.
• Across the Arctic-Boreal region, methane from wetlands, dust from newly exposed land, and carbon released by degraded ecosystems are feeding back into the global climate — and many of these systems are at or approaching tipping points beyond which change becomes irreversible.
The compilation is clear about what is needed now: coordinated pan-Arctic monitoring, ecosystem-based management, and policy-relevant pathways co-developed with Indigenous Kknowledge Hholders.
This work was edited by Torben R. Christensen (Aarhus University), Per Fauchald (UiT The Arctic University of Norway) and Marie Frost Arndal (Aarhus University), with editorial synthesis co-authored by Tom Christensen, and was supported by AMAP/CAFF support funds from the Danish Ministry of Climate, Energy and Utilities.
