edit: Note that these documents have not yet been substantiated, so these comments are based on the idea that they are, in fact, true:
Someone going by the handle "Heartland Insider" has anonymously released quite a few of what are claimed to be internal documents from Heartland, revealing the Institute’s strategies, funds, and much more.
In this document they say:
[Dr. Wojick's] effort will focus on providing curriculum that shows that the topic of climate change is controversial and uncertain – two key points that are effective at dissuading teachers from teaching science.
They are literally, even by their own wording, trying to manufacture a controversy, and prevent the teaching of science.
How much you want to bet that this gets little traction in the corporate media, while "Climategate", the manufactured controversy that had no substance to it, got so much?
