There is for certain no stochastic function whatever. Climate-system is like for example, almost every fish-system. They are overloaded. <br /><br />How can science change there views from doctrins that is contributing to nothing. Neither case, we schould act by slowly downsize the global circulation of money and use oil only for important servicesAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-7641626425728151830.post-16639187634368768652011-02-17T11:09:36.955+11:002011-02-17T11:09:36.955+11:00David, the "approx 3°C" figure is the sh...David, the "approx 3°C" figure is the short-run sensitivity. Climate science textbooks put the long-run sensitivity in the neighbourhood of five to six degrees, or approximately double the immediate-response sensitivity.<br /><br />It takes time for the ice to melt, the ocean to warm, and for low-albedo forest to replace higher-albedo tundra - all positive feedbacks. The practitioners know about them, but are focused on a reasonable policy horizon - a century, rather than a millennium. Hence the three-degrees-per-doubling mantra.<br /><br />Paleoclimate evidence is about the long run. Are you saying that this paper says long-run climate sensitivity is now thought to be higher than the textbook five-or-six degrees per doubling? That would be troubling indeed.<br /><br />Update: on reading the linked commentary, I see that the paper is about resolving the long-standing difference between estimates from soil carbonate and those from other paleoclimate measures. Yet another anomaly bites the dust, and the consensus is confirmed.Greghttps://www.blogger.com/profile/11939046017258198038noreply@blogger.comtag:blogger.com,1999:blog-7641626425728151830.post-27932295082660235202011-02-17T07:38:59.616+11:002011-02-17T07:38:59.616+11:00Thanks for letting me know - I fixed the links now...Thanks for letting me know - I fixed the links now.David Sternhttps://www.blogger.com/profile/16744705511660270649noreply@blogger.comtag:blogger.com,1999:blog-7641626425728151830.post-82286093405641542642011-02-17T06:55:16.578+11:002011-02-17T06:55:16.578+11:00David, some of those links are brokenDavid, some of those links are brokenrognoreply@blogger.com
