Widespread reversal of vegetation resilience in permafrost ecosystems.

From 2000–2023 satellite records in permafrost regions, vegetation resilience rose at first but reversed widely after 2008, with the strongest link to intensifying atmospheric drought.

• Why it matters: Warming is destabilizing permafrost ecosystem functioning, but how vegetation resilience evolves during permafrost degradation—and whether greening reflects stability—remains unclear.
• What they did: The study analyzed satellite observations from 2000 to 2023, testing drivers of vegetation resilience changes and using evidence from ocean evaporation and atmospheric moisture transport, plus wildfire impacts.
• The result: After 2008, vegetation resilience declined despite continued greening, implying destabilized plant carbon uptake and indicating that climate models may underestimate drought-driven risk in high-latitude carbon sinks.
