<div>Regarding the previous post today <font size="2">"[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:</font></div>

<div>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: </div>

<div>At website below read a paper published in the Proceedings of the National<br>Academy of Sciences in Dec. 2009, by Vermeer and Rahmstorf, where they state<br>that "ocean heat uptake is not sufficiently understood" revealed by the fact<br>
that "observed sea level rise exceeded that predicted by models" for the<br>examples they list. They explore errors in climate models in this paper.<br><br>The climate model Rahmstorf uses for the physics of the oceans accounts for<br>
this uncertainty, if I understand correctly.<br><br>However, this uncertainty does not lead the authors to conclude that the<br>predictions of significant sea level rise by 2100 due to climate warming<br>from human impacts, are largely unreliable, given a range of predictions for<br>
sea level rise, 75 to 190 cm (.75 to 1.9 meter), from 1990 to 2100. Note<br>this prediction states that IPCC AR 4 (2) predictions of sea level rise are<br>lower than their findings, if I read correctly:<br><br><font size="4">*Global Sea Level Linked to Global Temperature*<br>
