结论	Restoring atmospheric concentrations to preindustrial levels could prove possible at acceptable cost in two scenarios: (1) a best-case carbon capture scenario in which direct air capture technology achieves its most optimistic cost and performance assumptions and (2) a low-cost capture and abatement scenario in which reducing greenhouse gas emissions also proves relatively inexpensive. Setting a climate restoration goal could catalyze the deployment of negative emissions technologies that remove greenhouse gases from the atmosphere. But such a goal could also reduce the likelihood of successfully decarbonizing the global economy. Pursuing a climate restoration goal would avoid such a moral hazard under conditions in which successful negative emissions technology is at least half as likely as successful decarbonization. If climate restoration proves possible and catalytic, it would reduce the risks of extreme climate change and make meeting other climate goals more likely. In the longer term, the pursuit of climate restoration has some favorable policy persistence characteristics. If the technology proves viable, a growing climate restoration industry might promote policies favorable to its continuation and growth.
摘要	An ambitious climate restoration goal might seek to achieve preindustrial concentrations, not by 2050 but toward the end of the 21st century — perhaps by 2075, according to some reckonings the 300th anniversary of the beginning of the Industrial Revolution. To avoid the risk of overshoot, a climate restoration goal might best be combined with a 2°C temperature target. Climate restoration would be a public good. Efforts to ensure the necessary funding for midcentury climate restoration activities would benefit from near-term attention to longer-term financing mechanisms. Adopting a risk management framework and regarding the approach to climate change as a process of policy experimentation could help society achieve the opportunities offered by a climate restoration goal and avoid the adverse effects.
