Some of it is a bit odd to tell the truth.<br /><br />For example, take this bit about the IPCC's decision to reduce the lower bound on its estimate of climate sensitivity down to 1.5°C.<br /><br />The IPCC had lowered the bottom end of the range, down from the two degrees C it had set in its Fourth Assessment Report, issued in 2007. The IPCC based the lowered bound on one narrow line of evidence: the slowing of surface warming during the past decade—yes, the faux pause.<br /><br />However, those who have read the relevant parts of the Fifth Assessment and indeed those who are familiar with the recent Lewis/Crok report on climate sensitivity will be aware that the IPCC actually gave a completely different explanation for their decision to reduce the lower bound.<br /><br />The lower temperature limit of the assessed likely range is thus less than the 2°C in the AR4, but the upper limit is the same. This assessment reflects improved understanding, the extended temperature record in the atmosphere and ocean, and new estimates of radiative forcing.<br /><br />I don't know about you, but I count that as three lines of evidence not one.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4142988674703954802.post-68023919724832232562014-03-19T10:46:15.155-07:002014-03-19T10:46:15.155-07:00can't even be bothered to read past the headli...can't even be bothered to read past the headline. <br /><br />Just add it to all the other predictions that never happened and then go and throw them all in the bin.williamhttps://www.blogger.com/profile/05960834231015865831noreply@blogger.com
