The Heartland Institute has organized and hosted 15 International Conferences on Climate Change (ICCCs) since 2008, the latest (ICCC15) in Orlando, Florida on Feb. 23-25, 2023. Heartland also hosted two events called the America First Energy Conference in Houston, Texas on November 9, 2017 and in New Orleans, Louisiana on August 7, 2018.

These events have attracted extensive international attention and some 6,700 attendees to the debate taking place in the scientific community over the causes, extent, and consequences of climate change. Videos from Heartland's climate conferences — as well as videos organized by speaker — can be browsed at the link menu bar above.

The International Conferences on Climate Change are a project of The Heartland Institute’s Arthur B. Robinson Center on Climate and Environmental Policy, which produces an ambitious program of research and educational projects in defense of free-market environmentalism. That effort has brought together hundreds of scientists and economic experts to participate in the production of books, including four volumes in the Climate Change Reconsidered series rebutting the alarmist reports of the United Nations’ Intergovernmental Panel on Climate Change. Heartland also produces a steady stream of policy studies, videos, a monthly public policy newspaper called Environment & Climate News, a weekly e-newsletter (Climate Change Weekly), events, and other educational activities.

The 15th International Conference on Climate Change (ICCC15) attracted some 300 scientists, economists, policy experts, and guests willing to question whether man-made global warming is a problem worth addressing. The event, with the theme of "The True Crisis: Climate Change or Climate Policy?," was hosted by The Heartland Institute and CFACT, and featured more than 50 keynoters and panelists.

At ICCC15, two awards were given out. Dr. Christopher Essex received received the Frederick Seitz Memorial Award for “Exceptional Courage in the Quest for Knowledge” from the Science and Environmental Policy Project (SEPP). CFACT presented Jo Nova the the Dauntless Purveyor of Climate Truth Award. Click here to visit a website devoted to award winners and to learn about how to sponsor awards at future conferences.
