Assume that all the nations of the world fulfill their obligations under the Kyoto Protocol (they won't!), which reduces global emissions about 5% below 1990 levels. That results in a "savings" of global warming of 0.07Cº by 2050--an amount too small to measure, as global temperatures vary on their own about twice that much from year-to-year.

Assume that all the Kyoto countries adopt -- and fulfill -- MS 2191. The amount of saved warming in 2050 is around 0.11Cº, and about 0.20 in 2100. Too small to measure. The accumulated cost? Probably in excess of 10 trillion dollars.

The Electric Power Research Institute in Palo Alto, California, calculates that even if the US, Europe, and Japan turned off every power plant and mothballed every car today, atmospheric CO2 would still climb from the current 380 parts per million to a perilous 450 ppm by 2070, thanks to contributions from China and India. (Do nothing and we'll get there by 2040.) In short, we're already at least lightly browned toast. It's time to think about adapting to a warmer planet.

Poland has joined Germany in calling for industry exemptions to EU climate rules as a recession in Europe's major economies is casting doubts on whether Brussels will be able to push through its ambitious CO2 reduction programme...

Member states are getting nervous about asking their industries to pay more for CO2 pollution, says Christian Egenhofer, a senior researcher at the Centre for European Policy Studies (CEPS) in Brussels. The "assumptions have gone", Egenhofer said in reference to likely declining investments and growing constraints on governments' abilities to use macro-economic instruments towards 'green' aims.
