#1 Wasn't this hyped by the Global Warming crowd a few years back, only to be proven WRONG?

#2 The MMGW crowd always yells at us when we take one weather event to show that global warming isn't happening how they think, then they take one small point in time and say how the world will end.

Everything is proof that man is changing the climate, cold or hot and anything saying something else is heresy.

#3 Really?

The highest elevation in Greenland - a "mountaintop" summit, is 2.295 miles above seal level (https://en.wikipedia.org/wiki/List_of_mountain_peaks_of_Greenland#Highest_major_summits).

Looking at Greenland, this summit towers above the surrounding land.

Here is topographic representation of elevation in Greenland http://polarmet.osu.edu/jbox/data/sublimation_figure.gif

Now, the radius of earth is 3961.3 miles, or 20,915,664 feet, at sea level.

So - raising sea level 20 feet would mean changing seal level to 20,915,684 feet from Earth's center.

Now, there is whole lot of land interfering with any calculation of ocean volume, based on increase in sea level. And - Earth is not a perfect sphere.

But - lets do the simple numbers:

Volume of a sphere = 4/3 x pi x (radius) cubed.

Earth (before) = 4/3 x 3.141586 x (20,915,664 feet) cubed - and then compute cubic miles by dividing by (5,280 feet) cubed.

260,375,964,295 cubic miles

Earth (after) = 4/3 x 3.141586 x (20,915,864 feet) cubed - and then compute cubic miles by dividing by (5,280 feet) cubed.

260,383,433.677 cubic miles.

Volume differential: 7,469,382 cubic miles.

Now - figure in land mass that accounts for some of the increased volume. Land account for 29% or 30% of Earth's surface. Let's say 29.5%. So - assuming that 70.5% of the volumetric increase of the sphere's volume is water, that is 526,591,431 cubic miles of additional water, to raise sea level 20 feet.

Surface area of Greenland is 836,300 square miles. Add 2 miles of ice sheet over THE ENTIRE COUNTRY, and you get 1,672,600 cubic miles of ice.

Compare 1,672,600 cubic miles of ice - if ALL of Iceland was two miles deep in ice, and it all melted - and created the same volume of water - to 526,591,431 cubic miles of additional water needed, to raise sea level 20 feet.

By my thumbnail calculations, Greenland - if ALL ICE TWO MILES THICK - AND THEN COMPLETELY MELTED could produce 0.0031764 of the required amount of sea level rise, compared to 20 feet. That is - an increase in ocean depth of 0.7623 inches.

Now, there are lots of deviations from ideal - oceanfront contour of land mass - and also variations in ice thickness on Greenland's land surface - and the fact that melting ice produces a decreased volume of liquid water - and the fact that the ENTIRE ice sheet does not melt - but - in general - the article exaggerates by a factor of at least 315 times.

Total bullshit.

#4 I used the wrong value for Pi - should be 3.1415926 - but this is pretty much angels dancing on the head of a pin. The numbers in the climatista article are still orders of magnitude off from reality.

#5 So if my house gets flooded I can move to Greenland?

#6 Anybody check your math, Lone Ranger?

I have no doubt your concept is correct, but before I pass it along to my family, I'll check the math!

I applaud your logical approach. I wonder if any of the warmers could follow it?

#7 Bravo Mr. Ranger.

This maps into my problems with the whole scam.
30 yrs as a bit banger including 5+ years as a systems auditor.

Those few pieces of code in e-mails from climate gate have enough issues to put the whole scam to bed.

Garbage in, garbage out.

It's bad enough when the GI is mistakes. This is deliberate lies.

#8 Closer to six feet.
Volume differential: 7,469,382 cubic miles.

That much would raise the sea level 20', if it was all water. Since 30% is land, that much would raise the sea level closer to 26 feet.

So the volume of Greenland's ice is 1,672,600 cubic miles of ice, or about 22% of the 26 feet rise, or about 5.8'.

Still, very conservatively overestimates by a factor of four, compared to warmist numbers. But the science is settled.

#9 My thoughts are:
Multiply 2 miles of ice by the ratio of Greenland's surface area to the Earth's wet surface area (which is 70% of total surface area):

2mi * (Greenland Surface Area) / (Earth Wet Surface Area)
= 2mi * (836300~~mi^2~~/(0.7*196.9M~~mi^2~~)
= 10560ft * (0.0061)
= 64 feet

Which would wipe out most of the blue area on most maps.

It's a good thing. :-)

#10 Oh my God how can we possibly save Greenland, said nobody.

#11 Oh my God how can we possibly save Greenland, said nobody

Where will all the mosquitos go?

New Jersey?

Fire Island?

#12 Kind of makes you wonder how humanity survived the era when Greenland was, you know, green land?
