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

Geoengineering does little to defuse most of the risks that really matter for people - and it runs the risk of making some harms worsePlanetary-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...
