No warming

The Reference Frame summarises new research on temperatures in the troposphere:

Christy, Norris, Spencer, Hnilo (ADSABS) have studied the temperature of the lower troposphere in tropics (-20...+20 latitude) during the 1979-2004 period in their article in Journal of Geophysical Research (2007).

They used two sources, UAH (University of Alabama in Huntsville) and RSS (Remote Sensing Systems). The nighttime trend is 0.12 K/decade while the daytime trend is 0.07 K/decade - a strange difference indicating that an adjustment may be needed.
[...]
... the surface warming trend is 0.13 K/decade while the troposphere is only 1/2 of it, and even when you add the error margin, it is still less than the surface trend and much less than the trend 0.17 K/decade predicted from the surface trend by the AGW climate models.

The opinion that there's no warming in the troposphere at all seems alive while the opinion that the warming in the troposphere is dominated by the greenhouse effect doesn't seem to be alive.
