[Repeal The 17th]

“...containing enough water to raise ocean levels by about 20 feet...”

I need to see the math before I believe that.

So they think it’s floating just like Guam? 20 ft ?

STFU

Just doing it quickly...and not necessarily without error....it would take an ice sheet of 1,000 meters thickness covering Greenland’s area to raise the area currently covered by the world’s oceans 20 feet. I see a figure of 2-3,000 meters...real precise, I know...for the thickness of Greenland’s ice sheet. I have no idea how much land area would be flooded. but it must be pretty substantial.

That’s pure climate change BS propaganda. That amount of ice is like an ice cube in a bathtub.

Unfortunately.. the believers will say NASA says so.

Numbers are from web searches and rounded.
Area of Greenland ice sheet 660235 Sq Mi.
Average thickness of Greenland ice sheet 0.95 Mi
Ice volume 660238 Sq Mi x 0.95 Mi = 627223 Cu Mi
Density convert ice to water 627223 Cu Mi x 0.9 = 564500 Cu Mi
Area of earths oceans 1.4 x10(8) Sq Mi
Sea level rise 564500 / 1.4 x10(8) = 0.004 Mi
Mi to feet 0.004 Mi =21 Ft
That would be a vertical rise, that does not take into account sloped shore lines and water level rise in river deltas, so the ocean rise would be less. Some one else needs to figure that out.
