The confessions of a Greenpeace founder. Key quote:

Other quotes of interest:
The collapse of world communism and the fall of the Berlin Wall during the 1980s added to the trend toward extremism. The Cold War was over and the peace movement was largely disbanded. The peace movement had been mainly Western-based and anti-American in its leanings. Many of its members moved into the environmental movement, bringing with them their neo-Marxist, far-left agendas. To a considerable extent the environmental movement was hijacked by political and social activists who learned to use green language to cloak agendas that had more to do with anti-capitalism and anti-globalization than with science or ecology.
And:
There is no cause for alarm about climate change. The climate is always changing. Some of the proposed “solutions” would be far worse than any imaginable consequence of global warming, which will likely be mostly positive. Cooling is what we should fear.
