And Alexander Cockburn? It may be the first, last and only time this happens--but I guess it had to happen once. Here he compares the selling of "carbon credits" with the selling of indulgences in the medieval Catholic Church. A taste:
The modern trade is as fantastical as the medieval one. There is still zero empirical evidence that anthropogenic production of carbon dioxide is making any measurable contribution to the world’s present warming trend. The greenhouse fearmongers rely on unverified, crudely oversimplified models to finger mankind’s sinful contribution--and carbon trafficking, just like the old indulgences, is powered by guilt, credulity, cynicism and greed.
