Any conference worth its salt needs a long list of sponsors to give the impression of widespread diverse support for whatever the conference organisers are advocating.

In the case of the Heartland Institute and its advocacy for the denial of the risks of human-caused climate change, its just-started conference for climate science misinformers in Chicago includes official supporters from as far and wide as India, England, Austria and New Zealand.  Attendees may discuss Heartland's recent billboard campaign which used a picture of the Unabomber Ted Kaczynski to claim that "most prominent advocates of global warming aren’t scientists. They are murderers, tyrants, and madmen".
