Basically some scientivists have carried out a study using a computer model that was originally funded for a different application by NASA, and the conclusion is that the world needs to adopt eco-socialism, or face the collapse of civilisation.
The study was originally reported in the Guardian by Nafeez Ahmed. I get the impression that Ahmed is seen by the Guardian and the BBC (he's been interviewed a few times by the BBC) as being the new George Monbiot.
Re: You tube has a number of very interesting videos on epidemiology
If only NASA could separate itself from the Hansen Climate Science in just the same way they are busy putting distance between themselves and this study.
There is a certain amount of fudging around the funding issue and Nasa'S remit that makes you wonder whether these funds weren't misapplied but now no-one dare say anything.
