Bad News About the Polar Vortex

This Winter has been colder and snowier in the Northeast than it has been in almost 20 years. Obviously, it's too soon to declare this a trend, but this video from Dr. John Holdren, Director of the Office of Science and Technology Policy, suggests that the southward drift of the polar vortex is a predictable result of climate change and that we can expect more frequent colder winters.

On the other hand, I don't remember hearing anyone predict this movement of the polar vortex, so this analysis may be influenced by hindsight bias. It also illustrates the fact that when “global warming” is renamed “climate change,” the theory is better able to accommodate almost any change that occurs.

By the way, Dr. Holdren, a respected expert on climate change and energy policy, has held this important advisory position ever since President Obama took office. Why does he seem to have so little influence over administration policy?
