The conversation of what to do about global warming is winding down over at Cato Unbound. I’ve found the discussion fascinating, and I learned a lot. I’d like to see a lot more discussions like this one about climate change policy, and I hope we set a decent example. There were some mildly raised voices, sure. But there’s also been a whole lot of data and scientific and economic reasoning exchanged. I guarantee that if you read through all the essays and replies, you’ll learn something.
