An interesting side-story about HadCRUT4. Look at RealClimate, March 20, 2012 “Updating the CRU and HadCRUT temperature data” by gavin:
the difference between 1998 and 2010 is in the hundredths of a degree, and most of the attribution work on recent climate changes is looking at longer term trends, not year to year variability. However, there is now consistency across the data sets that 2005 and 2010 likely topped 1998 as the warmest years in the instrumental record
Compare that now to Skeptical Science, April 18, 2012 “First Look at HadCRUT4” by dana1981:
In HadCRUT4, the hottest years on record are 2010 and 2005, with 1998 right behind in a statistical tie.
From the quotes above, it is difficult to ascertain if Gavin Schmidt has any understanding of the meaning of a difference “in the hundredths of a degree” (hint: for all scientific intents and purposes, it’s a difference of zero). The point that “there is now consistency across the data sets” seems to indicate an obsession with numbers and a forgetfulness of the underlying physical aspects of climate.
Even Dana Nuccitelli, amid the usually flurry of anti-skeptic rants and dubious interpretations passed as Truth, appears to have a better grasp on science itself.
Note that among the scarce number of comments (83), a couple of people try to make this simple point, only to be told by the likes of tamino that it doesn’t matter because of evil skeptics of course. As if surgeons would regularly use subpar anaesthesia justifying themselves by saying there are evil doctors out there doing far worse.
Building up on Paul Penrose’s comment at JS:
How is this news if the results are not statistically significant? Or do people not know what that means? Once you take that into account what they are saying is: News flash – global temperature has not increased since 1998!
Actually, the news flash should be that, since 1998:
- Global temperature has not increased in any meaningful manner
- Northern Hemisphere temperature has not increased at all (some bits of the Arctic aside)
- At most we could talk of an Arctic, not Global Warming
- All of the above, despite all the continuous fudging and cooling of the past
Once again…Whatever Arctic warming there’s been, it’s also been inconsequential. And if HadCRUT4 doesn’t kill Global Warming, it certainly helps putting it in the right place..
Ungracious loser James Annan couldn’t wait posting about the new all-singing all-dancing HadCRUT4 dataset, showing “that reports of the death of global warming have been somewhat exaggerated“.
It’s really really hard to avoid laughing when adjustments come out of thin air but anyway…let’s consider HadCRUT4 less of a joke for a moment.
Since temperatures go up by including the upper Arctic, it is obvious that the rest of the world, and especially the inhabited regions, have not warmed as expected.
And a 5C increase in an area where the average is -20C is _not_ the same thing as a 5C increase where the average is +10C. The former is inconsequential, the latter a change in all seasons.
So HadCRUT4 simply confirms things are going as predicted only in faraway places where there are few measurements and nothing is really changing anyway.
If this doesn’t kill global warming, it certainly helps putting it in the right place.
