New research has moved up the time by which the Arctic Ocean is predicted to be free of summer ice.
To do so, the scientists first teased out the effect of greenhouse gases from other factors that affect sea ice loss, such as artificial chemicals from aerosols or natural events such as volcanic eruptions. The impact of aerosols was found to be negligible and the study concluded that natural events contributed no more than 10 per cent of sea ice loss.
But once the model had been brought in line with what was happening on the water, predictions of summer ice disappearance got a lot closer. By comparing ice extent year-over-year — February 2019 against February 2018, for example — the data showed ice loss from climate change in every month of the year.
