Risks of geoengineering smaller than risks of climate change.
If we do not undertake geoengineering, the effects will be much worse than anything that could happen if we did work with it and possibly even made mistakes. The tests that have already been carried out have been very successful with limited or no unintended consequences. Examples include solar radiation projects (such as using pale-colored roofs to reflect the sun’s light, and doing the same to pavement). Other test projects such as the iron fertilization of algae blooms have gone well, with little or no consequences.
