“a study published in April which said the Arctic would start losing its ice in summer very soon, even if we managed to rapidly reduce carbon emissions in the short-term.
“This really surprised us,” said Dirk Notz of the University of Hamburg, who led that research. “The Arctic will become practically sea-ice free in September before the year 2050… in all scenarios.”
But a closer look at CESM2 has suggested a potential explanation for the extreme result – it could simply be wrong.
Climate scientists used to predict an ice-free Arctic every summer, but are getting smarter now and push their worthless forecasts out past their retirement date.
