A definition of political insanity is doing the same thing over and over, expecting different results. Based on that, politicians supporting the so-called "solutions" to man-made global warming -- Kyoto accord, cap-and-trade, carbon taxes, renewable energy -- are insane.
That's because none of these things has worked in the real world -- assuming the goal is to lower man-made carbon dioxide emissions -- and yet they keep promoting them.
The UN's Kyoto accord is a fiasco, falsely billed as a global treaty to combat global warming.
In fact, Kyoto was ratified by a few dozen industrialized countries who are a small part of the problem -- including (under Jean Chretien) Canada, with 2% of global emissions.
The accord places no demands on China, the world's largest emitter, or on the entire developing world, where emissions are now rising the fastest.
It doesn't impact the U.S., the world's second-largest emitter, which never ratified Kyoto.
Since China and the U.S. are responsible for 40% of global emissions, Kyoto, or any successor treaty which doesn't include them, obviously won't work.
