Geoengineering the Arctic Ocean to boost its reflectivity, or albedo, will not result in any overall mitigation of climate change. That’s the conclusion of a group of US scientists, who have simulated how the climate would respond to increased albedo amid high carbon-dioxide concentrations.
Geoengineering is controversial: opponents claim that costs are uncertain, as are wider ramifications for the environment. But a bigger question is whether the approaches would even reduce warming as they intend, which is why Ivana Cvijanovic and Ken Caldeira at the Carnegie Institution for Science, US, together with Douglas MacMartin at the California Institute of Technology, addressed this puzzle for ocean-albedo modification.
