New study makes a case for geoengineering half-measure

Geoengineering, the deliberate large-scale interventions in the earth’s climate system to control a runaway global warming, is no more than a false dawn for a majority of researchers, environmentalists, and activists, who have time and again pointed at the disastrous consequences of these techniques.

Now, a new report gives a cautious welcome to the idea of solar radiation management, which would involve spraying certain particles in the atmosphere to block sunlight and reflect it back into space to cool the planet, writes Earther.

The report, published in journal “Nature Climate Change” backs half-measures instead of full-fledged geoengineering, explaining that the approach could be fruitful in reining in global warming without unleashing the adverse impacts, such as disruption in precipitation and evaporation, to the tunes predicted by earlier studies.

The report, however, remains silent on the extent of the role geoengineering could play if it were to be employed for reversing global warming. Previous studies have found that dimming the sunlight could do more harm to crops than the benefits expected from cooler temperatures, notes Futurism.
