CambridgeModels miss 1 million km² of Arctic winter ice loss.
The Arctic’s winter ice maximum hit a record low in March 2025 and tied it this year.
Cambridge researchers weighted 27 climate models by how well they reproduced sea ice 6,000 years ago, measured from algae biomarkers.
Winter ice loss has been linked to colder winters and heavier snowfall in the UK and northern Europe.
