Glenn Reynolds has posted a short piece that grapples with climate change and what to do about it. I agree with most of it, although the man-made impact in global change is surely, at this point, more than "far from certain." It's "very likely." Glenn is right that carbon-based energy is dumb and dirty anyway, even without the climate change drawback. And I second the notion that we need to make green reform innovative and entrepreneurial rather than of the take-your-medicine variety. I'm also intrigued by the idea of making a new and hefty carbon tax revenue-neutral. It might help sell it to the right: cut income tax and tax carbon instead. But there's no need to ban private jets. Just tax the bejeesus out of them. A little sugar for the left as well.
