The authorsfind that, given the uncertainty in the climate system, focusing on atmospheric greenhouse gas concentrations is likely to convey a false sense of precision.

For more than twenty years, policymakers have struggled to find ways to reduce greenhouse gas emissions enough to stop global climate change. Congress is likely to enact federal climate legislation in 2009, but many scientists fear that emissions reductions may not occur quickly enough to prevent significant warming. Some scientists...

The consequences of global warming are hard to predict, but geoengineering might well be the only feasible solution if they prove to be serious.

Since the beginning of the climate change story more than 20 years ago, it has been hard to sort out whether the IPCC represents the “best” science, or merely the findings most compatible with the politically driven climate policy agenda. Both sets of Climategate emails have lifted the lid on the insides of the process, and it isn’t pretty.

Geoengineering could prove to be a viable solution to global warming.
