Scientific advisor to the White House links the polar cold wave in U.S. to climate change

US scientists push back at contrarian claims that cold weather disproves climate change.

Obama’s science advisor, John Holdren, took on the climate change deniers in a two-minute video. “If you’ve been hearing that extreme cold spells like the one 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.”

But he concluded: “I believe the odds are that we can expect as a result of global warming to see more of this pattern of extreme cold in the mid-latitudes and some extreme warm in the far north.”

The White House has taken a far more pro-active approach to climate change denial in Barack Obama’s second term.

The president in a milestone climate speech last June rejected the validity of denier arguments, saying: “We don’t have time for a meeting of the Flat Earth Society.”

Since then, White House officials and outside campaign groups have worked noticeably harder to shore up public support as the Administration moves forward with regulations to cut carbon emissions from power plants.

The Environmental Protection Agency recently published its proposed standards for future power plants.

There was little sign however that the most prominent climate change deniers would alter their views.
