New paper finds the 'fingerprint of man-made global warming' doesn't exist

A new peer-reviewed paper published in Energy & Environment confirms from the latest satellite data that the tropospheric "hot spot" or so-called "fingerprint of man-made global warming" predicted by climate models does not exist. The authors find surface warming exceeds tropospheric warming, the opposite of model predictions, suggesting there are fundamental flaws in the physical assumptions of the models.

Abstract: In 2000 a panel of the U.S. National Research Council in a report with the same title suggested, among other things, that a "substantial disparity remains" between the observed warming rates of the surface and troposphere. Also, in 2000, the climate models showed more warming of the tropical atmosphere than was observed. Many papers have been written since then. We discuss the most recent papers on this subject and using the latest data show that the differences remain unresolved.

Prior posts on the "hot spot"


  1. ITCZ hot spots were another chimera, the heat's all going um - into the oceans now [giggle].

    Hot spots in the models, had they never heard of adiabatic lapse rates?

    A dry lapse rate of 5.5°F/1,000 ft (10°C/km)

  2. As I read the ice core data it appears that we are about due, or perhaps overdue, for an extended period of cooling. Could the start of that long term cooling be what's been observed over the last 15 years?

  3. If anything has been learned about climate change it is that scientist will lie to gain money for research work . It is nothing more than a way to get money in the till so they can party and have a great time talking amongst them selves. With no thought to how this will effect our economy at all .
