Your math is off. Ice is 1/11th Air. So when it melts in Greenland, only 10/11ths are turned into water. So even more than 10,000 feet would have to melt for this much sea rise.

For those who know if you leave a glass full of ice water and all the ice melts the glass doesn't overflow.


Do me a favor... go in your kitchen and fill a glass of water all the way to the top.. Right up to the rim. Now, put a bowl with a bunch of ice cubes in it and put that in the microwave on high until it melts. Now, pour that melted ice into the glass and report back here on what happens.

(I don’t believe the Greenland story btw, but this stupid argument needs to go away)

So all the rivers that run into the ocean don't make the sea level rise but some ice in Greenland is going to kill everyone? Makes sense.

So for the ocean to rise 23 feet, nearly 10,000 feet of ice (nearly 2 miles high) would need to melt.....

According to wiki, the thickness of said ice sheet ranges from 6600-9800 feet thick.

question the math here, not saying it is wrong, but the numbers dont make since

area of ocean: 361,900,000 square miles
area of Greenland: 836,300 square miles

ratio of area of ocean to Greenland: 433:1

so for every 433' of ice thickness in greenland that melts, the ocean will rise 1'. So for the ocean to rise 23 feet, nearly 10,000 feet of ice (nearly 2 miles high) would need to melt.....




I ran the math. It seems correct. I'm getting 8 meters but I'm assumed current water surface area. Of course water surface area will increase so the height will decrease to approximately 7 meters.

But this is not the issue. The issue is making the assumption that the Greenland Ice Sheet is melting at a faster rate than ever and implying that 100% of the Greenland Ice Sheet will melt away.

This article demonstrates why that is not true: LINK

Here's the TL:DR version:



25,000 years ago the Greenland Ice Sheet was at it's lowest estimated/calculated volume.

Conclusion

From this geological perspective, the Greenland Ice Sheet is not behaving badly.

Ya gotta love "if" statements like this with literally NO reference to the likelihood of it occurring.

And you were being kind because water EXPANDS when it freezes meaning that 1 foot of ice =/= 1 foot of water.

I understand how they arrived at the 7 meter rise in sea levels. But the fact that the article implies that 100% of the Greenland Ice Sheet will melt is complete bull shite.

If this is a catastrophe it's a very very slow moving catastrophe and humans are very good a responding to slow moving catastrophes. It's a catastrophe on a geologic time scale. I'm not worried.

This would take 3,000 years to happen. Solutions would arise.

Marked safe from 7m sea level rise

I'm around 200' on a mountainside.

Well that's the funny part. They just kinda throw in that "if" statement and let the reader do the implying in their own head.

It would be like having a toddler reach up and pull one of your hairs out and someone said, "if she kept doing that, you'd be bald".

Well no frick. But that's kinda irrelevant!

You can reduce that 7 meter rise by 1/5 then.

What does the rise in water level matter anyway? If all the ice melted wouldn't this mess up the salinity of the NAC and kill all of us anyway?
