- When we began our study, we felt that skeptics had raised legitimate issues, and we didn’t know what we’d find. Our results turned out to be close to those published by prior groups. We think that means that those groups had truly been careful in their work, despite their inability to convince some skeptics of that.
- UC Berkeley physics professor Richard Muller • Explaining how he went from being a prominent figure in the world of climate change skepticism and denial, to somebody convinced of its reality. Muller was no shrinking violet on this matter; he had once decried the scientific consensus on this issue as “polluted by political and activist frenzy.” However, after heading up the Berkeley Earth Surface Temperature project, which analyzed a tremendous amount of temperature data, Muller found that his numbers matched up neatly with the scientific consensus on climate change (he found the earth’s temperature has risen about 1.8 degrees Fahrenheit since the 1950s). Muller’s conclusion? “Global warming is real.” source
