There’s grim, mixed news out about Antarctica.
Two new papers on melting Antarctic ice come just days after NASA scientists announced the discovery of a massive subterranean hole in West Antarctica’s Thwaites Glacier, the Florida-sized hunk of ice which alone could unleash more than two feet of sea-level rise should it collapse.
One study found that all this melting could have surprising and profound impacts on weather while the other (controversial) study scaled back previous Doomsday estimates. Still, the takeaway from both studies is clear: If we keep on our current path, things could go downhill for humanity very, very quickly.
The worst-case scenario that’s emerging is shockingly bad
In the first paper, an international team of researchers examined the impacts of melting ice on global ocean circulation and weather patterns.
As relatively cool, salt-free meltwater spreads from Antarctica and Greenland across the world’s oceans, it will have dire impacts:
