What really matters is that the trend of all the records is roughly the same (up until recently when the satellite records started to diverge), no matter what the baseline period. And that's the only thing that really matters in the end.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2313427464944392482.post-49548637396433188462015-05-15T00:47:55.456+10:002015-05-15T00:47:55.456+10:00Interesting one, Tony.

For example, the GISTEMP anomaly of 0.75C for April is measured against a baseline of 1951 - 1980 average temp, while for UAH the baseline period is exactly 30 years later, 1981 - 2010, when temps were much hotter on average. April 2015 comes in with a nice, low anomaly of 0.07C there. But if you then consider the analysis here:<br /><br />http://www.woodfortrees.org/notes#baselines<br /><br />You can see that even if the plots for GISTEMP and UAH are aligned to the same baseline period (1981 - 2010), UAH is still running on average ~ 0.2C colder that GISTEMP (if you look at the difference during periods of relative ENSO stasis, that is. Because during extreme El Niñ0/La Niña events, the satellite records are all over the shop).<br /><br />Then if you look at the plot above that with the original, skewed baseline periods, you can see that UAH is running on average about 0.5C colder than GISTEMP there. Question for Roy: why is it 0.2C colder?<br /><br />Anyway, deniers seem to just love comparing apples with oranges. The result, of course, = bananas :-)Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2313427464944392482.post-65470916121136801192015-05-14T18:20:54.146+10:002015-05-14T18:20:54.146+10:00No worries, it's the same trap as last time - ...No worries, it's the same trap as last time - you plotted the running average!<br /><br />:-)Bernard J.https://www.blogger.com/profile/16299073166371273808noreply@blogger.comtag:blogger.com,1999:blog-2313427464944392482.post-89404224269695351012015-05-14T18:17:16.518+10:002015-05-14T18:17:16.518+10:00Sou, you said that April 2015 was an average of 0....Sou, you said that April 2015 was an average of 0.75°C above the 1951-1980 mean but my eyeball perceives it as closer to 0.79°C above the mean. Perhaps I need new spectacles?<br /><br />Whether 0.79°C or 0.75°C, it's still an alarming surge. As I noted in the previous instalment in this series the back end of the year needs to be spectacularly cool even to bring 2015 to just scraping over 2014 as the warmest year on record, and this in the face of a rumbling <i>El Niño</i>.<br /><br />One could argue that this is just another blip like 1998, but if so they're coming closer together and with unabated enthusiasm, and with the underlying cause being completely unaddressed to date and for the foreseeable future, the prospects for the biosphere look grim indeed.Bernard J.https://www.blogger.com/profile/16299073166371273808noreply@blogger.comtag:blogger.com,1999:blog-2313427464944392482.post-12641253673407517152015-05-14T15:50:51.856+10:002015-05-14T15:50:51.856+10:00They are worried that their flying pigs will get f...They are worried that their flying pigs will get frostbite :)Souhttps://www.blogger.com/profile/08818999735123752034noreply@blogger.comtag:blogger.com,1999:blog-2313427464944392482.post-83184595714472105442015-05-14T15:34:17.795+10:002015-05-14T15:34:17.795+10:00Anthony and Roy are touting the cool April.
