Note from the editor: On April 24, U.S. Environmental Protection Agency (EPA) Administrator Scott Pruitt released a proposed rule that would restrict which scientific studies EPA could use in creating new regulations. The move — already controversial when it was first revealed over a month ago — would prevent EPA from considering studies in which the data is not available to the public, including the private health information of individuals in medical studies, and which is based on one-time events, such as the 2010 BP oil spill in the Gulf of Mexico.

Prominent climate Science deniers were in attendance at the EPA announcement, including Marc Morano, Steve Milloy, and Will Happer.
