Global Warming is Causing Cold Spells
Pro: Climate Change Cause Global Weirding
Here’s a video from Katherin Hayhoe discussing this issue.
It’s freezing outside, so all that talk about global warming is just a bunch of hooey…right?
But how is global warming to blame? (for the cold weather)
The answer is simple: because the phenomenon that causes the polar vortex to break down is known as sudden stratospheric warming, where the upper layers of the atmosphere increase in temperature by approximately 30–50 °C (54–90 °F) over the span of only a few days. The fact that there are land masses located where they are in the northern hemisphere means that as those land temperatures increase, they transport their heat to even more northern latitudes.
The polar vortex, typically, is a single-cell or double-cell region concentrated at polar latitudes….

The exact details of how this works are complex, but the explanation is simple: warmer land temperatures, particularly in northern North America and northern Eurasia, allow more heat to be transported into the Arctic stratosphere. A warmer Earth makes sudden stratospheric warming events more likely and more frequent. And those events destabilize the polar vortex, bring cold air down into the mid-latitudes, and cause the extreme weather we’re experiencing right now.
