All Scientists are Sceptics ~Professor Bob Carter

Whenever someone asserts that a scientific question is “settled,” they tell me immediately that they don’t understand the first thing about science. Science is never settled. Dr David Deming

Perhaps the most frustrating aspect of the science of climate change is the lack of any real substance in attempts to justify the hypothesis ~Professor Stewart Franks

Clouds act as a negative feedback and cause significant cooling

A new paper published in Geophysical Research Letters (as reported by The Hockey Schtick)

JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 117, D13103, 7 PP., 2012
doi:10.1029/2012JD017626
A paper published today in the Journal of Geophysical Research finds that a natural atmospheric oscillation, the Southern Annular Mode, is correlated to significant increases in cloud cover resulting in "large scale" local cooling of approximately -2.5C. All climate models falsely assume clouds result in net positive feedback and increased temperatures, however this new paper and several others show clouds instead result in net negative feedback and cooling.
Key Points
  • Sudden regional increases in cloud cover are detected over S. America
  • Changes linked to the Southern Annular Mode
  • The cloud changes are associated with regional temperature reductions
