Global Warming and the current "Polar Vortex"

Does it add up? The Earth is warming, and yet many US locations are about to equal or exceed previous low temperature records.

In a nutshell, earth and climate science support what is happening. The northern hemisphere jet stream is being slowed by arctic warming, and in slowing, it is becoming more erratic in its north south wanderings. These larger wanderings are allowing very cold arctic air to spill farther into the US, just like is now happening.

Want to get more scientific than me? Sure you do, so visit QUARTZ, and do watch at least the short video by Jennifer Francis of Rutgers University.

Climate Change and the Jet Stream

The above video does an excellent job of relating global warming to jet stream changes to extreme weather events. It is from The Yale Forum on Climate Change and the Media. Definitely worth watching. Be sure to hit the full screen button in the lower right.
