there does not appear to be a body of work establishing the basic criteria for a claimed causal relationship between the purported pollutant, anthropogenic carbon dioxide, and the claimed effect, global warming; atleast not outside of the...

In my opinion, the best carbon sequestration is already done: leave the coal under the ground....
Increased use of nuclear (an outright competitor to coal as a deliverer of baseload power) is essential to combat climate change
The location for this year's Camp for Climate Action - outside the Kingsnorth power station in Kent - was well chosen:...
The nation's leading climate scientist had a pointed suggestion for policymakers interested in reducing carbon dioxide emissions: no more coal plants.
"We need politicians with the guts to say that, but I don't see that," said James Hansen, director...
A critical fact is the long lifetime of CO2 emitted by fossil fuel burning. Half of a fossil fuel CO2 pulse disappears within 20-30 years, mostly into the ocean. However, much of the CO2, about one-fifth, is still in the air after 1000...
Dr. James Hansen testified on June 23rd, 2008 that: “A wide gap has developed between what is understood about global warming by the relevant scientific community and what is known by policymakers and the public. …Frank assessment of scientific...
Background
James E. Hansen (born March 29, 1941 in Denison, Iowa) heads the NASA Goddard Institute for Space Studies in New York City, a part of the Goddard Space Flight Center in Greenbelt, Maryland, Earth Sciences Division. He is currently an adjunct professor in the Department of Earth and Environmental Sciences at Columbia University, and also serves as Al Gore's science advisor. Hansen is best known for his research in the field of climatology and his testimony on climate change to congressional committees in the 1980s that helped raise broad awareness of the global warming issue. He is also noted for publishing "an alternative scenario" for global warming which states that in the past few decades the warming effect produced by increased CO2 has been largely offset by the cooling effect of aerosols also produced in burning fossil fuels, and that most of the net warming so far is due to trace greenhouse gases other than CO2. He has been a critic of both the Clinton and current Bush Administration's stances on climate change.
