Yesterday I talked about the phenomenon of "global dimming", where pollution particles suspended in the atmosphere reflect sunlight back into space. Because they cause less sunlight to hit the Earth, these particles also cool the planet.
So here’s an idea for fighting global warming. Instead of trying to reduce greenhouse gas pollution – the root cause of the problem – why not use technology to counteract the effect of the pollution? For example, we could artificially add to the planet’s reflectivity so that the warming is cancelled by the cooling.
