Myth: If all countries had signed and enacted the 1997 Kyoto treaty to reduce emissions, the world could have stopped global warming.

Reality: If we had spent that money, Kyoto would have cost about $180 billion a year. The reduction in temperature would have been about 0.008 degrees Fahrenheit by the end of the century. We’ve been doing climate change policy in the same failed way over and over. It’s about time that we realize the current approach is broken.
