Hoping that the politicians will do the right decisions for the wrong reason won't do. The AGW scare has compelled governments to direct resources towards reducing CO2 while neglecting other environmental issues. The lower bound of food prices has doubled because more bio fuel means less food and this is causing death and starvation in third world countries. A lot of windfarms have been built which is probably the most expensive and most unreliable source of energy on the planet. Furthermore projects about geological carbon storage (pumping CO2 underground) are currently being planned. And then there is Cap And Trade and the Carbon Swaps. The tax payers will not be able to get rid of this schemes as long as CO2 is used as a benchmark for measuring environmental impact.
