While much of North America is locked in the embrace of an overly amorous polar vortex, Noise to Signal is thawing out of its deep freeze for a cartoon or two. We’ll see how things go.

In the meantime, stay warm. (I have vivid Ottawa memories of my dad explaining that -40º was the point where the Fahrenheit and Celsius scales converge, and that cross-country skiing was maybe not such a great idea today.) And just a reminder that viciously cold weather doesn’t mean climate change isn’t happening — it’s actually one effect of warmer Arctic air weakening the jet stream, and letting polar air wander down to lower latitudes now and then.
