Several problems...
1. Based on ice core samples the earth has been worming over the last 30,000 years...the fifth cycle of warming and cooling over the last 500,000 years...even with no man made influence we could expect to see another two degrees of warming based on the previous 4 cycles, it just depends if we are at the peak...
2. The system is so complex it is nearly impossible to predict what is going to happen over the next 30,000 years
3. Even with indisputable proof of man being the cause of current warming we have little chance of dropping the climb as long as China, India, and others fail to contorl their CO2 emissions
4. CO2 emissions in the US are flat over the last 10 years... 1998 we emitted 5,616,170 million metric tons to 5.610.108 in 2010 (latest data available)

5. China has increased their emissions over the last 10 years by an amount that is equal to US annual CO2 emissions...1998 2,967,258 to 8,330,963...and they continue to build coal fired plant after coal fired plant...
6. US "Clean coal" requires scrubbing of several cubic miles of compressed CO2 each year and then injecting that compressed CO2 into the earth for eternity...yet we can't seem to find a way to store a much smaller amount of nuke waste for less time....
