ANAHEIM, Calif. (AP) -- President Barack Obama says denying climate change is like arguing the moon is made of cheese.
Obama issued a call to action on global warming in a commencement address Saturday to graduates of the University of California, Irvine.
Obama says in remarks prepared for delivery that Congress "is full of folks who stubbornly and automatically reject the scientific evidence" and say climate change is a hoax or fad.
He says others duck the question because they fear being "run out of town by a radical fringe that thinks climate science is a liberal plot."
Obama recently announced a contentious plan to cut power plant pollution.
Obama also used his address to announce a $1 billion fund for communities to rebuild and prepare for the impact of extreme weather.
