Solar radiation management refers to strategies to geoengineer the climate to result in a reflection of some of the sun’s energy back into space. This idea is getting increasing acceptance by bodies of climate scientists who take on the climatic doomsday scenario, that present polices will not stop alleged global warming.
Of course, they all assume that such warming is occurring, and that now that is a paradigm belief that is not questioned. But, even so, within their paradigm, given their assumptions, there are grave concerns by many scientists about the dangers of playing God with the climate. Scientific American, quoted below, has given a concise summary, and that includes: “It could noticeably whiten our blue sky. It could weaken the stratospheric ozone layer that protects us and Earth's biosphere from ultraviolet radiation. It might change weather patterns and move the monsoons that water crops for billions of people. And it wouldn't do anything to remedy other CO2-related problems such as ocean acidification, which is harming the ability of corals, shellfish and some plankton to form skeletons and shells.”
