Assuming that the climate response to multiple regions of banded SRM geoengineering can be shown to be roughly the addition of the individual climate responses, we can use the results of this experiment to identify theoretical limits to the extent that SRM geoengineering could compensate for human - induced climate change, a potentially highly relevant check on the weight trust that politicians should place on cheap geoengineering solutions in climate policy.

Building on these studies, this experiment will investigate the impacts of geoengineering simulations run using HadCM3L.

There are several variations on the so - called solar geoengineering theme, but they all have the same end - goal: using aerosols to blanket our atmosphere with reflective particles in order to quickly lower global temperatures.

Just as large volcanoes cool the planet by ejecting massive amounts of small particles into the stratosphere, one sunshade geoengineering proposal would involve using high - flying airplanes to release small particles in the stratosphere that would scatter sunlight back into space.

Geoengineering The term Geoengineering has been poisoned by the vocal (likely fossil - fuel funded) Chemtrail movement (I use the phase movement for politeness).
