Regarding the previous post today "[Vision2020] "Hard to Get Discussion
Going?" Re: Bill McKibben Commentary Re: 10:10 "no pressure" video" there is
mention of Barton Paul Levenson's list of estimates of climate sensitivity,
but the URL might not work correctly.  Here is a URL to this list that
should work, I trust:

http://bartonpaullevenson.com/ClimateSensitivity.html

I also thought I would add, given sea level rise is one of the most critical
predicted impacts of anthropogenic climate warming, that an important
scientific paper, that should receive a lot of exposure, published in 2009
in the Proceedings of the National Academy of Sciences, is referenced in one
of the sources from the "Hard to Get Discussion Going?" post, as I discuss
below, with a URL to the article:

At website below read a paper published in the Proceedings of the National
Academy of Sciences in Dec. 2009, by Vermeer and Rahmstorf, where they state
that "ocean heat uptake is not sufficiently understood" revealed by the fact
that "observed sea level rise exceeded that predicted by models" for the
examples they list.  They explore errors in climate models in this paper.

The climate model Rahmstorf uses for the physics of the oceans accounts for
this uncertainty, if I understand correctly.

However, this uncertainty does not lead the authors to conclude that the
predictions of significant sea level rise by 2100 due to climate warming
from human impacts, are largely unreliable, given a range of predictions for
sea level rise, 75 to 190 cm (.75 to 1.9 meter), from 1990 to 2100.  Note
this prediction states that IPCC AR 4 (2) predictions of sea level rise are
lower than their findings, if I read correctly:

*Global Sea Level Linked to Global Temperature*
