Retooling the Planet: The False Promise of Geoengineering

The notion of using geoengineering is moving from a fringe idea to mainstream discussion. Powerful corporations and governments of developed nations are the ones with the budgets and technology to execute geoengineering schemes. There is no reason to trust they will have the rights of more vulnerable states or peoples in mind,and the risk to the planet’s ecological integrity is great.

Chilling out globally

What has the atomic number of 16, and is liable, in the form of a compound, to be spritzed into the stratosphere by the mega-ton? You’d be right if you said sulfur. That’s one of the interventions suggested by geo-engineers to reduce global warming, along with such initiatives as making biochar, "sequestering" CO2 under the earth, brightening clouds by spraying water upwards, and dumping iron powder in the sea. A sulfur compound injected into the middle atmosphere would mimic a massive volcanic eruption, which is known to reduce the mean surface temperature.
