Plans to reduce solar radiation to slow the effects of global warming have the potential to be dangerous and should be banned by governments, a group of scientists and policy experts warn that such technologies could disrupt African monsoons and stunt crop growth.
One plan involves injecting billions of sulfur particles into the atmosphere, but the disadvantages of such a plan would far outweigh its success.
Phys.org’In an open letter published in the academic journal WIREs Climate Change, “Solar geoengineering practices cannot be managed fairly, inclusively and effectively globally” statements were included. The letter also called for political action, “We call for urgent political action from governments, the United Nations and other actors to prevent the normalization of solar geoengineering as a climate policy option‘ expressions were used.
Artificial dimming of the sun is likely to disrupt monsoons in South Asia and Africa and cause problems with crops. However, other places could benefit from it: it would reduce the likelihood of drought in southern Africa, for example. Nor will the technology do anything to stop the build-up of carbon dioxide in the atmosphere, which significantly alters the chemistry of the seas.
As stated in the letter, such hopes for a speedy resolution “removes incentives for governments, businesses and societies to do their best to decarbonize or achieve carbon neutrality as soon as possible“.
The letter calls for an international decommissioning agreement to prevent the financing and patenting of these technologies.
