President Barack Obama says the current understanding of climate science is infallible.

“The science is irrefutable,” Obama declared during a Monday press conference in Mexico, where he appeared with Mexican President Enrique Pena Nieto, and Canadian Prime Minister Stephen Harper.

“We’re already seeing severe weather patterns increase…[and that] has the potential of displacing people in ways that we cannot currently fully anticipate, and will be extraordinarily costly,” he claimed, as justification for the remarkable claim.

The statement strongly suggests that Obama will continue to block the Keystone XL pipeline in a State Department bureaucratic review. “Keystone will proceed along the path that has been set forth,” Obama told the press conference.

That strategy of professing complete faith in climate science gives him a better chance of turning out his environmental allies in the critical November midterm elections.
