In January 2012, the American Meteorological Society surveyed its professional members and found that 52% believe global warming is happening and is mostly human-caused, while 48 percent do not. The survey also found that scientists with professed liberal political views were far more likely to believe global warming is human-caused than others.
The authors of the survey recommended that the American Meteorological Society should 'acknowledge and explore the uncomfortable fact that political ideology influences the climate change views of meteorology professionals; refute the idea that those who do hold non-majority views just need to be "educated" about climate change; [and] continue to deal with the conflict among members of the meteorology community.'
So is Climate Science settled? No of course not. And why does Lynn Jones want to believe it is? Maybe her left-wing views, not 'liberal' as there's nothing liberal about supporting the rights of genocidal Islamist terrorists over that over the democratic multi-cultural state of Israel, could provide a clue.
