PODEX Experiment to reshape future of Atmospheric Science by getting a handle on aerosols and clouds

Polarimeter Definition Experiment (PODEX) in Southern California. The brightness, or “intensity,” and polarization of reflected light provide different information about the elements that make up a scene, apparent in this…

Quote of the week – Hansen concedes the age of flatness

Dr. James Hansen and Reto Ruedy of NASA GISS have written a paper (non peer reviewed) with a remarkable admission in it. It is titled Global Temperature Update Through 2012. Here…

Hansen and Karl to put on a "worse than we thought" event

From a press release, apparently the writer has no clue that the NASA GISS data is a derivative of the NOAA data, and thus the claim of “NASA and NOAA…

A problem: nearly one third of CO2 emissions occured since 1998, and it hasn't warmed

Guest post by Tom Fuller The physics behind the theory of global warming are solid. CO2 is a greenhouse gas, we’re emitting industrial levels of it, with China now in…

Is global warming just another 'End-of-the-World' delusion?

UPDATE: less than 24 hours after posting this, we already have an end of the world prediction naming global warming, see below. New end of the world book treats climate…

New paper blames about half of global warming on weather station data homogenization

From the told ya so department, comes this recently presented paper at the European Geosciences Union meeting. Authors Steirou and Koutsoyiannis, after taking homogenization errors into account find global warming…

Gavin on the ropes over heat wave explanation

Tom Nelson writes: If CO2 is really such an all-powerful warming factor, and if the science is so settled, why does warmist Gavin Schmidt have so much trouble explaining why…

James Hansen's climate forecast of 1988: a whopping 150% wrong
