In August 2015 the group held its 33rd annual meeting. While attacks on mainstream climate science are "a staple", the meeting provides a forum to a "broad" range of material. Presentations at the 2015 meeting included a theory about links between John F. Kennedy’s assassination and the deaths of his brother and son; a prediction that the aim of Obamacare was to cause the collapse the U.S. health-care system and a recommendation "that the audience start stockpiling medications and finding doctors who would work for cash"; a sympathetic discussion of the theory that low doses of radiation are "beneficial to human health"; and an argument that the HIV virus does not cause AIDS, but instead was invented by government scientists who wanted to cover up other health risks of “the lifestyle of homosexual men.” The meeting was covered by conservative website Breitbart, attended by George Gilder, and the conservative Heartland Institute sent its science director to present his plan to abolish the Environmental Protection Agency.
