To watchA nearly ice-free summer day in the Arctic could arrive before 2030
Published: December 2024 · study reference date
What happened
The simulations analyzed indicate that the first day with Arctic sea ice below one million square kilometres — the conventional threshold for a "nearly ice-free" Arctic — could occur before 2030.
This is not a forecast for a precise year, but one possible scenario among those compatible with climate models.
Why it matters
The rapid transformation of the Arctic is one of the clearest indicators of climate change and can produce consequences that go well beyond the polar region.
What we know — and what we still don't
To be verified / still uncertain
- The year in which the event will first occur.
- How often it may repeat in the following decades.
