What The HadCRUT4 Update Means

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:

  1. Global temperature has not increased in any meaningful manner
  2. Northern Hemisphere temperature has not increased at all (some bits of the Arctic aside)
  3. At most we could talk of an Arctic, not Global Warming
  4.  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..

HadCRUT4…not what it pretends to be!

Ungracious loser James Annan couldn’t wait posting about the new all-singing all-dancing HadCRUT4 dataset, showingthat 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.
