Drunken Arctic Freezes the US

Drunken Arctic Freezes the US reports Chris Mooney at MotherJones, as a large portion of the polar vortex, the mass of cold air that normally sits over the Arctic, broke off and moved south into the US, due to a weakening jetstream – think of it as a polar anuerism in the jetstream circulation. The jetstream is fueled by the temperature difference between pole and equator. As the pole warms, decreasing that difference, the moderately wavy jetstream starts to weaken, slowing and swinging wildly north and south more often, bringing wild, more prolonged temperatures and precipitation. (Remember when the rain decided to hang around in Colorado last summer?) Welcome to another wild year! Let’s hope the power stays on during the big freeze.

Join the swelling numbers of voters TELLING Congress they’ll vote for Clean Energy candidates here: http://signon.org/sign/we-are-the-clean-99?source=c.em.cp&r_by=487176 . This is an ongoing campaign (the next Congressional election is this year!) so please, spread the word. It’s our way of telling Congress that a strong clean energy voting bloc is out there. This is how YOU can make a difference.
