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.Full paper available hereReconciling Observations of Global Temperature Change: 2013David H.

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.
