With regard to the sequestration of excess carbon dioxide already in the
atmosphere and halocline, I'd like to see an entropy analysis of such a
procedure. The entropically entailed energy cost of removing the present
burden at a dilution 400 ppmv is very likely to be so large that a

There's also fresh input from Richard A. (and Waleed Abdalati) on Greenland
and sea level in this new dot earth post:

I try to avoid weighing in on subjects I don't know anything about, but
doesn't the below ignore albedo?
If it's snowy in Greenland, the effect of rising temperatures will be more
limited than if there's less snow.
Do we have any Albedo proxies? Do ice cores show flake size?

A sideshow to sea-level questions on policy-relevant time scales. (2100-ish
at best)..
You're talking geological scale here.
Tad Pfeffer's 2008 analysis of worst-case discharge rate still a keystone
to clear thinking on this.

Hi Adrian--Interesting question, but does not the domain of the entropy
analysis matter? Basically, one is going to be using materials to channel
solar energy (via wind power and growth of algae) into concentrated form,
that one then stores. So, letting solar energy just cause heating and then
Hi Andy‹I would just note that I am concerned that there may have been too
much focus on temperature and not enough on the fluxes of energy determining
the energy balance of the ice sheet; air to ice heat transfer is likely a
pretty small term. So, during the Eemian, there was a lot more summer

Hi Andy‹Your agreement with the dismissive statement on Greenland seems
terribly short-sighted. Over the coming decade (if not already), we¹ll be
setting a course for Greenland that will lead to much higher sea level in
the future (and the contributions from Greenland and Antarctica will end up
Three quick points.
First, Andy (if I may), I was responding to the following remark you made in
your NYT blog after Richard Alley's comment on the Dahl-Jensen article:
I do think [the new work] closes the case that Greenland, despite all of
its drama (moulins, for example) - drama that
