jm“what I like to talk about is ‘the Great Weirding’ and not just the Great Dying because the Great Dying seems to have been a relatively quick event at the very end. But if you just talk about the Great Dying you’re missing all of this other crazy stuff that led up to it,” he said. “The Earth was getting really weird in the Permian. So we’re getting these huge lakes with these negative pHs, which is really weird, we don’t know why that happened. Another thing is that the whole world turned red. Everything got red. You walk around today and you’re like, ‘Hey, there’s a red bed, I bet it’s Permian or Triassic.’ The planet started looking like Mars. So that’s really weird. We don’t know why it turned red. Then you have a supercontinent, which is weird in the first place. Plate tectonics has to be acting strangely when you have all the continents together. Eventually it rifts apart and we go back into normal plate tectonics mode, but during the Permian-Triassic everything’s jammed together. So there has to be something strange going on. And then at the end, the Earth opens up and there’s all these volcanoes. But we’re not talking about normal volcanoes, we’re talking about weird volcanoes.”
