There are problems with a geoengineering techno-fix for the climate crisis | Mike Hulme

Geoengineering does little to defuse most of the risks that really matter for people – and it runs the risk of making some harms worse Planetary-scale solar geoengineering interventions involve the deliberate injection of either natural or artificial particulates into the stratosphere – stratospheric aerosol injection, or SAI – with a view to offset some of the global heating caused by greenhouse gases.

If implemented, the technology would create a metaphorical thermostat for the planet. Such a thermostat is advocated on the grounds that controlling global temperature reduces the harms associated with the climate crisis . I wish to challenge this assertion. Continue reading...
