Barmy bloopers from John Christy and co at WUWT seven years later

Another Oh My! article has hit the denier-waves. This time from John Christy of UAH infamy, and friends (WUWT article with link is archived here, update here). It purported to be about green houses that are gassy, or something like that. The first sentence in the preface is:

On December 15, 2009, EPA issued its Green House Gas (GHG) Endangerment Finding, which has driven very significant and costly regulations beginning with CO2.  

Seriously. These guys claim to be writing about greenhouse gases and they don't even know how to spell greenhouse?

Warning: this is another long article.

Nine Denier 101 Techniques: Anthony Watts gets into a hot spot in the tropical troposphere

There's a new paper in ERL by Steven C Sherwood and Nidhi Nishant, which reports an updated version of their radiosonde dataset. It is probably going to cause quite a ruckus in the deniosphere. From the paper (my formatting):

Temperature trends in the updated data show three noteworthy features.

• First, tropical warming is equally strong over both the 1959–2012 and 1979–2012 periods, increasing smoothly and almost moist-adiabatically from the surface (where it is roughly 0.14 K/decade) to 300 hPa (where it is about 0.25 K/decade over both periods), a pattern very close to that in climate model predictions. This contradicts suggestions that atmospheric warming has slowed in recent decades or that it has not kept up with that at the surface.
• Second, as shown in previous studies, tropospheric warming does not reach quite as high in the tropics and subtropics as predicted in typical models.
• Third, cooling has slackened in the stratosphere such that linear trends since 1979 are about half as strong as reported earlier for shorter periods.

Wind trends over the period 1979–2012 confirm a strengthening, lifting and poleward shift of both subtropical westerly jets; the Northern one shows more displacement and the southern more intensification, but these details appear sensitive to the time period analysed. There is also a trend toward more easterly winds in the middle and upper troposphere of the deep tropics.

Radiosondes are instruments that are sent aloft in balloons, to take measurements in the atmosphere. (You might have seen Roy Spencer and John Christy combine measures from radiosondes with satellite tropospheric temperatures in their various unscientific attempts to befuddle the US government and readers of blogs.)
