The first summer on record that melts practically all of the Arctic’s floating sea ice could occur as early as the 2030s, according to a new scientific study — about a decade sooner than researchers previously predicted.
The peer-reviewed findings, published Tuesday, also show that this milestone of climate change could materialize even if nations manage to curb greenhouse gas emissions more decisively than they are currently doing.
Earlier projections had found that stronger action to slow global warming might be enough to preserve the summer ice.
The latest research suggests that, where Arctic sea ice is concerned, only steep, sharp emissions cuts might be able to reverse the effects of the warming already underway.
“We are very quickly about to lose the Arctic summer sea-ice cover, basically independent of what we are doing,” said Dirk Notz, a climate scientist at the University of Hamburg in Germany and one of the new study’s five authors.
