2. Make the clouds more reflective
A simple way to cool the planet down is to make clouds more reflective. Already, clouds are a major way the planet cools itself because they reflect light back into space. There is a lot of evidence that aerosols from cargo ships have helped make clouds more reflective, by adding more particles to clouds that reflect light even better than typical clouds do. Some scientists have proposed seeding clouds with sulfate particles, which are highly reflective, or perhaps with some yet-to-be-discovered particle X which would float in the stratosphere for years, reflecting light back into space. There are two big problems with this idea. One, we aren't entirely certain how hyper-reflective clouds would affect weather patterns. But more importantly, this is only a short-term solution. We'd have to be pumping particles into the clouds constantly. If we kept using fossil fuels during this time, the planet would become a greenhouse timebomb — if we were ever unable to keep the clouds reflective, the planet would heat up extremely rapidly and disasters would follow. So this is only a short-term solution to be used in connection with systems that would remove carbon from the atmosphere.相关的主题文章：
