Vilifying David Rose: Attacking The Messenger Over Sharp Drop In Land Temps
In the Mail on Sunday last week, David Rose penned an article pointing out the very sharp decline in RSS land only data to October 2016, indicating that ocean surface temperatures might also cool significantly soon and that perhaps scientists and the media over-played the role of man-made global warming in the spike in global temperatures in early 2016 which were precipitated by the natural warming event of El Nino 2015/16. Predictably, he has been vilified for doing so, called a denier, accused of cherry-picking the data to suit his ‘denialist’ agenda etc. etc.
All pretty familiar stuff now to those used to observing the spectacle which is warmist kick-back against any who dare to question any aspect of ‘The Science’.
James Delingpole then joined the fray and published at Breitbart, referencing Rose’s article, pointing out the “icy silence” from climate alarmists following the large drop in land temperatures (as measured by RSS satellite but also, as it happens, by GISS and UAH). Warmist fury peaked El Nino-like when the House of Representatives Committee on Science, Space & Technology had the audacity to tweet a link to Delingpole the Denier’s Breitbart article. Cue rants from the Keepers of the True Science of Climate Change and numerous other lesser warmist offendotron minions.
The main objection to Rose’s article is that he ‘cherry-picked’ land only data from the RSS lower troposphere dataset and ignored the oceans (he did not) and that (bizarrely) he cherry-picked two data points and ignored the longer record. The whole point of Rose’s article is that this is exactly what the media and scientactivists were doing when they hyped the El Nino to promote the anthropogenic global warming message! And they did. There is no doubt about that (as we shall see).
Firstly, let’s examine whether Rose’s ‘cherrypick’ of the RSS land only data was indeed a cherrypick. As you can see, UAH shows a very similar drop:
The GISS land only dataset shows a similar large decline:
So obviously, it was not simply Rose cherry-picking the data because the evidence is there : over land, temperatures dropped precipitously from Feb to Oct 2016. As Rose points out, the ocean data has been slower to respond, but it’s reasonable to speculate that, in 2017, the oceans might continue to cool (as they are now, and especially if a strong La Nina kicks in), whereupon the Pause in global warming might re-establish itself in which case the El Nino of 2015/16 will come to be seen as a short term weather event only, contrary to the hype we saw from scientists and the media at its peak. Of course, there is the possibility global temperatures might remain at a new higher level in which case we can say that El Nino has contributed to the long term global warming trend (as in 1998). The fact remains, however, most of the short term increase in temperature that we saw over 2014/15/16 can be attributed to the building super El Nino, not GHG global warming. This was not what scientists and the media were saying when El Nino peaked:
Adam Scaife (Met Office):
The vast majority of the warming is global warming, but the icing on the cake is the big El Niño event”
We think El Niño made only a small contribution (a few hundredths of a degree) to the record global temperatures in 2015.
The forecast for next year is about 0.8C above the 1961-1990 baseline. About 0.2 of that is likely to come from El Niño, hence the 25%
Peter Stott (Met Office):
El Nino will have contributed a “small amount on top” to the global warming of 2015/16.
When the peak did happen, Gavin was like, ‘Wow’ and this was ‘special’:
The Guardian, supported by comments from a number of scientists, concluded that the global warming occurring at the time was “shocking” and that it constituted a “climate emergency”. Which is odd because scientists are now publicly criticising Rose for writing an article which basically points out (correctly) that global warming was being hyped as the main cause of the extreme global temperatures in early 2016, using the current precipitous drop in RSS land temperature to back up his claim.
