I think some people are missing the point on the whole issue. Yes, we have fringes driving the discussion.
We have one fringe who are basically telling the West that evil capitalist industrialists are purposefully destroying the environment sending us into a massive downward spiral that will cause Mother Earth to get her revenge by earthquakes, tsunamis, hurricanes, etc. Therefore we must tax the ever loving daylights out of every multinational corporation to stop this apocalypse.
Another fringe denies there can be any change to climate at all.
The first fringe is large and works dilligently to pas laws which will ultimately do little to change what some call cyclical behavior but destroy a global economy as we know it. The second fringe is small and has no control over anything.
In the end, the credibility of the fringe group pushing for regulation is tainted when emails and admissions like we've seen come out.
Add to that, someone do some reading on Communism and environmentalism. Stalin had some tesing done within the ComIntern on pushing for environmental regulation. It was seen as a test to push a moderate stance that could be taken by all which could be applied at a legislative level to hinder capitalism. Since environmentalism was not exactly a popular idea of the day, nothing ever occurred. but since the 60's, read the propaganda by some of these fringe marxist groups who have taken up the cause - mainly for their own motivation of provoking severe regulation on capitalist economies. Look at who pushes this now. You hear the Marxist leaders of the world speak on climate change but never mention this as part of their own agenda. They are taking a mainstream type issue, pushing it in college campuses, third world nations, etc. in an effort to legislatively hinder capitalism.
