Greenland's ice sheet has melted past the point of no return

Published 8 mins ago on August 15, 2020
By Agence France-Presse



Greenland’s ice sheet may have shrunk past the point of return, with the ice likely to melt away no matter how quickly the world reduces climate-warming emissions, new research suggests.

Scientists studied data on 234 glaciers across the Arctic territory spanning 34 years through 2018 and found that annual snowfall was no longer enough to replenish glaciers of the snow and ice being lost to summertime melting.

That melting is already causing global seas to rise about a millimeter on average per year. If all of Greenland’s ice goes, the water released would push sea levels up by an average of 6 meters — enough to swamp many coastal cities around the world. This process, however, would take decades.

“Greenland is going to be the canary in the coal mine, and the canary is already pretty much dead at this point,” said glaciologist Ian Howat at Ohio State University. He and his colleagues published the study Thursday in the Nature Communications Earth & Environment journal.

The movie The Day After Tomorrow warned of this and that was released 16 years ago.

or an eruption like the 1815 Tambora event that made 1816 the “Year Without A Summer;” it snowed in Connecticut in June! If it happened now, it might be enough to bring temperatures back to “normal.”

U know of the 1815 Tambora eruption and the following 1816 lack of summer.

this is the true disaster of our time

the death toll from the rising tides will dwarf that of COVID-19
the secondary impacts from population dislocation and loss of arable land will reverberate for decades

we don't need a "space force", we need an "earth force" and it has to be a complete global mobilization effort
evolution will not provide humanity a solution, short of rapid extinction, so human society has to step in and pull a hat trick right the fuck now
or the die-off can proceed apace, our choice.
