Quite John. He discussed 20 feet of SLR should the Greenland ice sheet melt, with no specification of when it would occur (the implication was a few centuries – but I repeat, Gore mentioned no time-frame).

Where did Al Gore project 20-foot SLR by the end of the century?

[It's certainly not in AIT.]

I note Mr Brook’s mention of the outstanding question regarding the speed of ice sheet melt in Greenland, and the “possibly related post” — Al Gore’s projection of 20 feet of sea level rise by the end of the century.

These are indeed related, as the 20 foot projection is based upon a worst case scenario which assumes a virtual total loss of the Greenland ice sheet. I am not a scientist. But my intuition, based upon following climate developments for the past decade, suggests that this is now a foregone conclusion. The real question is, as Mr Brook points out, the impact of bottom lubrication and thus the speed and suddenness of the loss of the glacier.

Rising sea levels may be the least of the consequences, to be known only after the subsidence of the tidal wave.

4. Whether warming worsens storms …

Yes they do…
