Water scientist Peter Gleick admitted that he was the source for the anonymous leak of documents from the climate-change-denying Heartland Institute. The documents -- obtained under a false name, and then leaked -- showed Heartland's budget, corporate donors (Koch Industries and Philip Morris featured heavily), and a plan to produce deliberately confusing materials about climate change for use in middle school curriculum.
It is clear from the documents that Heartland advocates against responsible climate mitigation and then uses that advocacy to raise money from oil companies and "other corporations whose interests are threatened by climate policies." Heartland particularly celebrates the funding that it receives from the fossil fuel fortune being the Charles G. Koch Foundation.
Heartland also continues to collect money from Philip Morris parent company Altria as well as from the tobacco giant Reynolds American, while maintaining ongoing advocacy against policies related to smoking and health.
Heartland's policy positions, strategies and budget distinguish it clear as a lobby firm that is misrepresenting itself as a "think tank" - it budgets $4.1 million of its $6.4 million in projected expenditures for Editorial, Government Relations, Communications, Fundraising, and Publications, and the only activity it plans that could vaguely be considered policy development is the writing of a curriculum package for use in confusing high schoolers about climate change.
