This is a lie. The person that you are referring to when you say "it’s been estimated" is "blowing smoke" to obfuscate the issues and make people believe what he said. Tell the truth, don't just wave mirrors in the air and blow smoke.

Greenland Ice Covered Area = 1,755,637 kmē
Ocean Area = 361,000,000 kmē

Therefore (damn, I don't do km as well as I do inches.)

1,755,637 / 361,000,000 = how many meters the ocean will rise if 1 meter of ice melts ALL across Greenland.

That would be about == 0.0048632603878116343490304709141274

You tell us that if ALL the Greenland ice would melt that the oceans would rise 6.5 Meters. Lets see how thick the Greenland ice would have to be (above water, because we both know that melting the under water ice actually makes the oceans go down.)

6.5 meters / 0.0048632603878116343490304709141274 = Number of meters of ice (Everywhere there is ice) on Greenland. 1336.5519181926559989337203533882


So, Everywhere there is ice on greenland, it must be 1 and a third kilometers thick to do what you said. Everywhere. Tell whomever told you that, that they are wrong.

The second point I won't go into except to tell you to watch your movie again. The movie points out that pollution is causing the Global Dimming. There is no faster acting pollution than a Forest Fire. That pollution counteracts the threat you are worried about.

Lets see if I can explain the third point in twenty words or less.

Imagine that the sun is a huge Laser. Imagine that each drop of water in the clouds is one of those mirror balls that used to hang in Dance Clubs. Now, shoot the laser at the ball and count the photons that get reflected at the sun (i.e. reflect back into space.)
