Challenges, pitfalls and unintended consequences of relying on geoengineering to stop climate change
Modified jets spewing sulfuric acid could haze the skies over the Arctic in a few years “for the price of a Hollywood blockbuster,” as physicist David Keith of Harvard University likes to say. That’s geoengineering
, the deliberate large-scale manipulation of the planetary environment. This hazing, which mimics the cooling effect of a volcanic eruption, is so cheap that almost any country—or any random billionaire—could afford to do it, But even though it's too late to slow down the planetary warming triggered long ago by the carbon emissions of the industrial age, is geoengineering really the route we want to go?
