Climate activists massively outspend climate skeptics. The two largest U.S. environmental organizations, EDF and NRDC, have a combined annual budget of about $384 million compared to the mere $13 million of the two largest climate skeptic groups, Competitive Enterprise Institute and Heartland Institute. That amount of money, $384 million, is significantly more than all of the money Exxon gave to climate-skeptical organizations for two decades.
