“Since some twenty feet of sea-level rise is tied up in Greenland's ice, every coastal city in the world is at risk. The new study provides the strongest evidence yet that Greenland is more fragile and sensitive to climate change than previously understood -- and at grave risk of irreversibly melting off.”
That’s troubling enough for me.
- exporectomy 6y agoWhy? At predicted climate change induced melt rate for this century, that melting will take longer than the time just about any human city has ever existed on Earth. Do the maths before you get troubled by nothing.

- exporectomy 6y agoYes, that long.

- drewmol 6y agoThe phrase "irreversibly melting off" is troubling for me to read.
- yread 6y agowell it is irreversible - if it melts and the water flows in the ocean and mixes with the water there, there is no way to put it back. Of course if it cools down over the next few million years Greenland can grow a new glacier. But that will be a different one.
- silon42 6y agoGiven this article, it might be less irreversible then previously thought... but the CO2 will have to be removed from the atmosphere.
- TheAdamAndChe 6y agoThis argument is a bit like the "coal is a renewable form of energy because it eventually returns" argument. The consensus is that if the time scales required are on the order of thousands, tens of thousands, or millions of years, then it's safe to call it nonrenewable, and it is safe to call this irreversible on a human time scale.
- kevin_thibedeau 6y agoCoal exists because microorganisms and fungi capable of breaking down lignin didn't exist then. It will never be made again on Earth.
