It’s just the next stage in the mainstreaming of geoengineering: Now the House Committee on Science, chaired by Bart Gordon, has released a report supporting further research on the topic–not to the detriment of capping emissions, but because capping emissions might not be enough. Here’s the punchline:
Climate engineering, also known as geoengineering, can be described as the deliberate large scale modification of the earth’s climate systems for the purposes of counteracting and mitigating climate change. As this subject becomes the focus of more serious consideration and scrutiny within the scientific and policy communities, it is important to acknowledge that climate engineering carries with it not only possible benefits, but also an enormous range of uncertainties, ethical and political concerns, and the potential for harmful environmental and economic side effects. I believe that reducing greenhouse gas emissions should be the first priority of any domestic or international climate initiative. Nothing should distract us from this priority, and climate engineering must not divert any of the resources dedicated to greenhouse gas reductions and clean energy development. However, we are facing an unfortunate reality. The global climate is already changing and the onset of climate change impacts may outpace the world’s political, technical, and economic capacities to prevent and adapt to them. Therefore, policymakers should begin consideration of climate engineering research now to better understand which technologies or methods, if any, represent viable stopgap strategies for managing our changing climate and which pose unacceptable risks.

Honestly, one shouldn’t find the conclusion surprising. Anyone who really understands the scope of the climate problem, and the cost considerations that go along with mitigation, ends up being forced toward a view like this one. That’s just how reality works these days.
