Dim The Sun With Stratospheric Controlled Perturbation Experiment

Geoengineering or geomimicking? Volcanoes lower the amount of sunlight reaching the surface, thereby affecting climate. Can scientists do the same?


(Stratospheric Controlled Perturbation Experiment )

Harvard scientists will attempt to replicate the climate-cooling effect of volcanic eruptions with a world-first solar geoengineering experiment. The university announced this month that it has created an external advisory panel to examine the potential ethical, environmental and geopolitical impacts of this geoengineering project, which has been developed by the university’s researchers.

Known as the Stratospheric Controlled Perturbation Experiment (SCoPEx), the experiment will spray calcium carbonate particles high above the earth to mimic the effects of volcanic ash blocking out the sun to produce a cooling effect...

If we look at the second largest eruption of the 20th century, Mount Pinatubo, which erupted in the Philippines in 1991, it injected 20 million tons of sulfur dioxide aerosols into the stratosphere. Scientists from the USGS estimated that this 20 million tons only lowered the temperature of the planet by about 1°F (0.5°C) and this only lasted a year because the particles eventually fell to back to Earth.

Perhaps older SF fans recall the climate-tailoring effort in The Mote in God's Eye, the 1974 novel by Larry Niven and Jerry Pournelle, which used an actual volcano for the dispersal process.

Potter was doing most of the talking and all the pointing. "Those twin volcanoes; d'ye see them, Mr. Renner? D'ye see yon boxlike structures near the peak of each one? They're atmosphere control. When yon volcanoes belch gas, the maintenance posts fire jets of tailored algae into the air stream. Without them our atmosphere would soon be foul again."
