Once again pushback is required against scientists using climate models to promote their biased ‘human-caused warming’ agenda.

A new paper by Santer et al. provocatively entitled “Exceptional stratospheric contribution to human fingerprints on atmospheric temperature” goes where no serious climate scientist should go: it has conflated stratospheric cooling with global warming, says Dr. Roy Spencer (via Climate Change Dispatch).
The paper starts out summarizing the supposed importance of their work, which is worth quoting in its entirety:
Differences between tropospheric and lower stratospheric temperature trends have long been recognized as a “fingerprint” of human effects on climate. This fingerprint, however, neglected information from the mid to upper stratosphere, 25 to 50 km above the Earth’s surface. Including this information improves the detectability of a human fingerprint by a factor of five.
Enhanced detectability occurs because the mid to upper stratosphere has a large cooling signal from human-caused CO2 increases, small noise levels of natural internal variability, and differing signal and noise patterns.
Extending fingerprinting to the upper stratosphere with long temperature records and improved climate models means that it is now virtually impossible for natural causes to explain satellite-measured trends in the thermal structure of the Earth’s atmosphere.
The authors are taking advantage of the public’s lack of knowledge concerning the temperature effect of increasing CO2 in the atmosphere, making it sound like stratospheric cooling is part of the fingerprint of global warming.
It isn’t. Cooling is not warming.
