There is a LOT of conflicting information out there on climate science and the validity of the sources range from opinion blogs to peer reviewed meta-analysis Because of the conflict a new website has been created to try to bring to climate science the same level of fact checking seen on some of the political websites known for assessing truthfulness http://climatefeedback.org/feedbacks/ Let us see what it says about one of the more recent stories surfacing on this board
The website is the usual global warming promotion website. All the pieces promoting global warming are rated highly and all those questioning global warming are rated very low. The comments on Dr. Micheals' analysis (Michaels is an IPCC reviewer) actually include a link to a Media Matters smear piece. Here is how Karl, et. al. manipulated the data to produce a warming trend in the years since 1998. Ocean water temperature was measured using tubes mounted on ships. This measurement technique is known to produce temperature data that is too high due to the contaminating effects of heat produced by the ships. More accurate data from measurement buoys have gradually replaced the ship data over time. To make the new data homogeneous with the new data Karl adjusted the new data up by ~ 0.12 deg C (0.22 deg C) thus creating the temperature increase using bad data in the ERSSTv4 "data" set. Unbelievable !! This use of bad water temperature data can be seen in the plot of the difference between the ERSSTv4 and ERSSTv3 data set. The positive slope is seen starting in ~ Y2K and the positive difference starting in ~ 2005. Presto - global warming using dishonestly manipulated data. But even with this the real world data is significantly lower than the scenarios form the GCM models. Source - "Lukewarming" - Dr. Patrick Michaels - 2015 And from the Karl, et. al. report: http://sciences.blogs.liberation.fr/...-de-hiatus.pdf
Ya, it makes no sense to tie buoy measurements to ship measurements because ship temperatures can obviously vary more widely than ocean temperatures (much more mass in the ocean). Average differences are meaningless in this case.
