The prospect of the near total obliteration of summer Arctic sea-ice before 2035 should really be focussing all our minds on achieving zero carbon emissions in the 2020s.

“We’re never going to return to conditions like there were in the 1980s and 90s,” she says. “It’s not recovering. There are going to be ups and downs, but it’s never going to go back to what it was, given our current climate state today.”

What scientists refer to as the first "ice-free" Arctic summer year will occur when the Arctic has less than 1 million square kilometers of sea ice.eu.usatoday.com/story/news/nat…
Plenty of climate scientists dispute how catastrophic this will be. We know Arctic ecosystems are collapsing and any further exacerbation of global warming represents extinction for some species. Arctic experts expect global consequences & profound impacts.

'Global consequences' :
'An overwhelming majority of Arctic ice experts say that recent data offer powerful evidence that summer sea ice has passed a point of no return.'

From 2018: “This will have far-reaching implications, well beyond the Arctic,” says Julienne Stroeve of University College London, UK. “The impact of this sea-ice loss on climate at lower latitudes and sea-level rise will be profound.”
