This week we are joined by climate expert Greg Laden, who is here to talk to us about the polar vortex. If you’ve missed it, this winter is very cold and snowy and isn’t that completely not what climate change theory is telling us will happen? No, actually, it makes perfect sense. At least it might when Greg explains it. If you are a denier, it won’t. But you probably don’t listen to our podcast anyway. Which is just as well because you’re wrong and we have a real problem with you. You can find Greg’s blog here!
