"The Obama administration responded Wednesday to conservatives who say the historic cold snap affecting the United States proves that climate change is not real."
"The White House released a new video featuring Dr. John Holdren, the director of the Office of Science and Technology Policy, who explains that the "polar vortex" does not invalidate scientific consensus.
'If you’ve been hearing that extreme cold spells, like the one that we’re having in the United States now, disprove global warming, don’t believe it,' Holdren said. 'The fact is that no single weather episode can either prove or disprove global climate change.'
Holdren added that 'a growing body of evidence suggests that the kind of extreme cold being experienced by much of the United States as we speak is a pattern we can expect to see with increasing frequency, as global warming continues.'"
