Record low Antarctic sea ice 'extremely unlikely' without climate change, says scientists

Scientists at the British Antarctic Survey (BAS) have found that the record-low levels of sea ice around Antarctica in 2023 were extremely unlikely to happen without the influence of climate change. This low was a one-in-a-2000-year event without climate change and four times more likely under its effects. The results are published (20 May) in the journal Geophysical Research Letters, in a paper titled "CMIP6 models rarely simulate Antarctic winter sea-ice anomalies as large as observed in 2023."
