“If Al Gore reaches more people and convinces the world that global warming is real, even if he does it through exaggeration and distortion - which he does, but hes very effective at it - then let him fly any plane he wants.”
- Richard Muller, 2008 http://grist.org/article/lets-get-physical/
“There is a consensus that global warming is real. ...its going to get much, much worse.” - Richard Muller, 2008 http://www.wired.com/wiredscience/2008/11/physics-the-nex/
“Let me be clear. My own reading of the literature and study of paleoclimate suggests strongly that carbon dioxide from burning of fossil fuels will prove to be the greatest pollutant of human history. It is likely to have severe and detrimental effects on global climate.” - Richard Muller, 2003 http://www.technologyreview.com/energy/13423/page2/
“I was never a skeptic” - Richard Muller, 2011http://www.huffingtonpost.com/blackberry/p.html?id=1072419
