The slowing even the reversal of the Gulf Stream by fresh water discharge has been talked about for at least 20 or 30 years. It could be an “end state” of global warming or climate change, whatever you want to call it. But it is not the BRIEF article citing two studies that caught my eye…it was the snarcky stupid comments that followed. Is it possible for humans to devolve into maggots?

(Newser) – Scientists are raising alarm bells after two studies found that the Gulf Stream—an ocean current key to regulating Earth’s climate—is the weakest it’s been in 1,600 years, the Guardian reports. The culprit is apparently melting sea ice and glaciers, which inject fresh water into the North Atlantic and weaken the stream. “Fiddling with [the Gulf Stream] is very dangerous, because you may well trigger some surprises,” says climate scientist Stefan Rahmstorf. “I wish I knew where this critical tipping point is, but that is unfortunately just what we don’t know.” If the stream dies, scientists say, its equatorial heat would stop reaching the North Atlantic—plunging Europe into bone-numbing winters and affecting weather worldwide. Even subtler changes “could wreak havoc” on the Atlantic Ocean’s “delicate ecosystems,” Smithsonian reports.
Go there and comment. Oh I mean read. More next week.
