Leaked documents suggest that an organization known for attacking climate science is planning a new push to undermine the teaching of global warming in public schools, the latest indication that climate change is becoming a part of the nation’s culture wars.
The documents, from a nonprofit organization in Chicago called the Heartland Institute, outline plans to promote a curriculum that would cast doubt on the scientific finding that fossil fuel emissions endanger the long-term welfare of the planet. “Principals and teachers are heavily biased toward the alarmist perspective,” one document said.
While the documents offer a rare glimpse of the internal thinking motivating the campaign against climate science, defenders of science education were preparing for battle even before the leak. Efforts to undermine climate-science instruction are beginning to spread across the country, they said, and they fear a long fight similar to that over the teaching of evolution in public schools.
In a statement, the Heartland Institute acknowledged that some of its internal documents had been stolen. But it said its president had not had time to read the versions being circulated on the Internet on Tuesday and Wednesday and was therefore not in a position to say whether they had been altered.
Heartland did declare one two-page document to be a forgery, although its tone and content closely matched that of other documents that the group did not dispute. In an apparent confirmation that much of the material, more than 100 pages, was authentic, the group apologized to donors whose names became public as a result of the leak.
The documents included many details of the group’s operations, including salaries, recent personnel actions and fund-raising plans and setbacks. They were sent by e-mail to leading climate activists this week by someone using the name “Heartland insider” and were quickly reposted to many climate-related Web sites.
Heartland said the documents were not from an insider but were obtained by a caller pretending to be a board member of the group who was switching to a new e-mail address. “We intend to find this person and see him or her put in prison for these crimes,” the organization said.
Although best-known nationally for its attacks on climate science, Heartland styles itself as a libertarian organization with interests in a wide range of public-policy issues. The documents say that it expects to raise $7.7 million this year.
The documents raise questions about whether the group has undertaken partisan political activities, a potential violation of federal tax law governing nonprofit groups. For instance, the documents outline “Operation Angry Badger,” a plan to spend $612,000 to influence the outcome of recall elections and related fights this year in Wisconsin over the role of public-sector unions.
Tax lawyers said Wednesday that tax-exempt groups were allowed to undertake some types of lobbying and political education, but that because they are subsidized by taxpayers, they are prohibited from direct involvement in political campaigns.
The documents also show that the group has received money from some of the nation’s largest corporations, including several that have long favored action to combat climate change.
