Geoengineering — deliberate, planetary-scale efforts to counter the impact of climate change — is so controversial that a high-powered 18-member Washington task force that spent almost two years studying the idea couldn’t decide what to call it.
Most want to rename it “climate remediation.” A few want to stick with geoengineering. But all agreed that, whatever you call it, the U.S. government should begin “a coordinated federal research program to explore the potential effectiveness, feasibility, and consequences of climate remediation technologies.”
In a 33-page report released today in Washington, the task force of the Bipartisan Policy Center emphasized that climate remediation is not a substitute for managing the risks of climate change through mitigation (i.e., reducing emissions of carbon dioxide and other greenhouse gases, most of them generated by burning fossil fuels). It also says that no geoengineering technology is ready for deployment.
But, the group said, it’s imperative that governments, scientists and engineers learn more about geoengineering because the risks of climate change are increasing.
Mitigation measures currently being considered, regardless of their pace of efficacy, will not be able to return atmospheric greenhouse gas concentrations to pre-industrial levels for centuries…
Although we do not know exactly how much the climate will change or how fast, globally disruptive or even catastrophic results are possible…Global climate change could unfold in ways that would be very difficult to manage
In plain language: what we’re doing (or not doing) now to deal with climate change isn’t working, and the consequences of those failures are likely to be disastrous.
“I’m not sure we would have had a consensus recommendation on research if mitigation efforts were going great guns,” said Stephen Rademaker, co-chair of the task force and a former assistant secretary of state during the Bush II administration. [click to continue...]
