Pielke at least can be counted on to cite approximately 3 of his papers in every 5 sentences he writes to support his contentions that surface measurements are flawed and uncertain and that climate is influenced by more than just greenhouse gases. (to give him some credit, neither contention is entirely wrong, just not as important as he claims).<br /><br />-MMM<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7729093380675162051.post-74063278719691682442015-04-28T01:06:23.988+10:002015-04-28T01:06:23.988+10:00Nick, looks like I did not have had to write my ow...Nick, looks like I did not have had to write my own post.

On the contrary, I suspect that GHCN adjustments have cooled the temperature trend of the recent century, and that adjustments in "key areas" is one possible cause of the alleged global warming slowdown.<br /><br />I looked at adjustments in GHCN stations in the Arctic area (>70 degrees N), which had been active after January 2000. I found that 11 of them had been adjusted down, and no one up, during this period.<br />There are few stations in the Arctic area, which makes them relatively important in global temperature series that use infill techniques over empty areas, like GISTEMP and Cowtan & Way kriging.<br /><br />Nick, if I have got it right, Your TEMPLSmesh-index have a large degree of infill, and uses unadjusted GHCN data.<br />Actually TempLS mesh show the largest trend (1.34 C/century) of all global indices in the recent century (Jan 2000-Mar 2015). It's more than C&W kriging (1.09 C) or C&W hybrid (1.19 C). According to the tool in your February 5 blog post, the use of unadjusted data in TempLSmesh increase this trend with about 0.3 degrees.<br /><br />If I've got everything right, this is really interesting, and maybe stuff for a scientific paper... I can see the headlines "GHCN adjustments have slowed the global warming, no real hiatus, etc" :-)Olofnoreply@blogger.comtag:blogger.com,1999:blog-7729093380675162051.post-90287761643140623672015-04-27T12:30:56.143+10:002015-04-27T12:30:56.143+10:00re: "However, it has a reasonably qualified p...re: "However, it has a reasonably qualified panel, so it may be interesting to see what they develop."<br /><br />Also reasonably counter-consensus in their purported views on climate change.robinhttps://www.blogger.com/profile/10532350850997056373noreply@blogger.comtag:blogger.com,1999:blog-7729093380675162051.post-86997162586358495392015-04-27T12:09:44.140+10:002015-04-27T12:09:44.140+10:00Damn.

These effects include radiometer non-linearity, imperfections in the calibration targets, emission from the primary antenna, and antenna pattern adjustments.
