> Ultimately it's up to us how much ice actually melts. "Humanity has the knob—the carbon knob, and that knob is going to influence the rates of ice loss from the Greenland ice sheet."

Hey, didn't you know, there is an ice age coming ....

In 1970, The Boston Globe ran the headline, "Scientist predicts a new ice age by 21st century." The Washington Post, for its part, published a Columbia University scientist's claim that the world could be "as little as 50 or 60 years away from a disastrous new ice age."

Do you have a source for that number?

Here's a direct link to the study: https://essd.copernicus.org/articles/10/1551/2018/essd-10-15...

Relevant quote:

> Almost all land ice (∼99.5 %) is locked in theice sheets, with a volume in sea-level equivalent (SLE) termsof 7.4 m for Greenland and 58.3 m for Antarctica. It has beenestimated that approximately 25 % to 30 % of the total landice contribution to sea-level rise over the last decade camefrom the Greenland ice sheet

7.4 m corresponds to 24 feet so their claims are accurate.

Also, 58.3 m.... that's shocking. Predicted sea level rise until the end of this century is well below that but imagine the massive effort needed to deploy 69 m tall walls at our coastlines... scary as hell. Likely we'll just give up a lot of land.

High seawater is honestly a minor issue compared to the rest if our climate heated up enough for the entire antarctica to melt...

Sea level has the advantage it is happening here, it is measurable and has a predictable financial impact. Not saying this is the proper way to look at it but it is a way to get it through to some people who may see their grounds flooded in their lifetimes. Actually it it already matters now if the next generation buyers believe the place is going to be flooded during their lifetimes. The more certainty we get the more it will impact prices and insurance. People do not ignore those and there are plenty living close to the sea. Again it is a lagging and not proper way of looking at it but we need to reach people who are not able to absorb more complex stuff.

If there was a 216ft sea level rise we'd still have a lot of land globally, but it would be quite devastating to the US, especially along the east coast. Florida would literally vanish beneath the waves. https://www.nationalgeographic.com/magazine/2013/09/rising-s...

Check the contributions section here https://en.wikipedia.org/wiki/Sea_level_rise or just cmd+f for "24 ft"

Very nice, thanks. So Greenland's area is about 2 million km^2 and the area of all oceans is about 360 million km^2, so the average thickness of the ice on Greenland is roughly 24 feet * 360/2 = 1.3 kilometers. That's an unimaginably huge amount of ice! Apparently the thickest point is 3 km! https://en.wikipedia.org/wiki/Greenland_ice_sheet
