The Bad Astronomer writes "Last week, an anonymous source leaked several internal documents from the Heartland Institute, a non-profit think tank known for anti-global-warming rhetoric. The leaker has come forward: Peter Gleick, scientist and journalist. In his admission, he cites his own breach of ethics, but also maintains that all the documents are real. This includes the potentially embarrassing '2012 Climate Strategy' document stating that Heartland wants to 'dissuade teachers from teaching science.' Heartland still claims this document is a forgery, but there is no solid evidence either way."
