Previous attempts to create a cap and trade system to stem pollution at the federal level have failed due to concerns it would cause skyrocketing energy costs, a particularly bruising prospect in an already wobbly economy.
Also in October, a prominent climate skeptic whose research was funded in part by the conservative billionaire Koch brothers' foundation announced he had found that mainstream projections of climate change were correct and unbiased.
"We confirm that over the last 50 years, temperature has risen 0.9 degrees Celsius, or 1.6 degrees Fahrenheit. This is the same number that the IPCC (UN Intergovernmental Panel on Climate Change) says," physicist Richard Muller, director of the Berkeley Earth Surface Temperature Project, told lawmakers.
Muller said he hoped other climate skeptics would agree with his work, but his newfound stance -- accepted by the vast majority of scientists -- remains rogue, particularly among Republicans seeking to replace President Barack Obama in 2012.
