Moore is far from popular with his former NGO and other Greens, in January 2012 he spoke about the Green folly of wind power describing it as "a destroyer of wealth and negative to the economy."
Then in July 2012 Moore caused more Green outrage and upset when he attacked the warming alarmists for their attempts to cover up the lack of warming for what was then 15 years.
"These people are either completely naive about the relationship between CO2 and plants or they are making this up as a way of deflecting attention from the lack of warming for the past 15 years", said Moore.
In August that year Moore gave an interview to the Washington Times:
On February 25th 2014 Moore appeared before the U.S. Senate Environment and Public Works Committee, his former NGO really will not like what he had to say:Ideology is negative in so far as it tends to divide people into warring camps with no possible resolution. My late Greenpeace friend Bob Hunter suggested early on that in order for environmentalism to become a mass movement, it would have to be based on ideology, or as he called it "popular mythology," because "not everybody can be a Ph.D. ecologist."
