Solar Geoengineering Projects
Could Be More Effective on Regional Scale

A new modeling study by several geoengineering experts suggests that injecting aerosols into the atmosphere to block more of the sun’s energy and reduce temperatures could be most effective when done on a region-by-region basis. The study, published in the journal Nature Climate Change, said that

Thinking the Unthinkable: Engineering Earth’s Climate
Last year, a U.S. panel urged more research into proposals to manipulate the climate to slow global warming. Jane C. S. Long, the group’s chairwoman, explains why we need to know more about the possibilities and perils of geoengineering.

injecting aerosols over the Arctic Ocean in summer, for example, might be an effective way to not only slow the rapid loss of Arctic sea ice but possibly even restore it to pre-industrial levels. The researchers — led by David Keith of Harvard University, Ken Caldeira of the Carnegie Institution for Science, and Douglas McMartin of the California Institute of Technology — cautioned that their models were rough and that bringing about changes in regional climate patterns can have global effects. But they said the study shows the need for more detailed research into how solar geoengineering techniques could be used to slow or reverse the effects of climate change on rapidly warming areas. “Our research goes a step beyond the one-size-fits-all approach to explore how careful tailoring of solar geoengineering can reduce possible inequalities and risks,” said Keith.
