Aggie Joke : Dessler’s Error Is Greater Than His Trend

Estimates of Earth’s climate sensitivity are uncertain, largely because of uncertainty in the long-term cloud feedback. I estimated the magnitude of the cloud feedback in response to short-term climate variations by analyzing the top-of-atmosphere radiation budget from March 2000 to February 2010. Over this period, the short-term cloud feedback had a magnitude of 0.54 ± 0.74 (2?) watts per square meter per kelvin, meaning that it is likely positive. A small negative feedback is possible

In other words, his study is a waste of paper.

    Wow – does it really take 7 months of review time to accept a paper in Science these days ?

    This is just another example of all the previous reports released by Dressler. For the most part he gets the entire situation backwards because warming causes more clouds. A lack of clouds allows more energy into the weather system which increases evaporation and produces more clouds.

    Oh yeah, climatology “statistics”. Since when is 2 sigma (67% of the range) what counts? Riiiight, +/- 1.0 would make the slope of 0.5 even less “significant”.

    Not only did they redefine the peer-review process, they are establishing a new approach to statistical analysis….and not an accurate one.
