As climate change gets worse, and as no clear path to cutting down emissions in a major way emerges, scientists are increasingly considering ways we could re-engineering the Earth itself to cool it down. One of these geoengineering ideas is to pump gases into out upper atmosphere. As we've seen after volcanic eruptions, sulfuric gasses like SO4 will marginally shade the Earth by blocking certain segments of incoming light.
This sunglasses-effect, if sustained, could help to put the brakes on our planet's rising temps. But according to a new study out today, it also could slow one of the most severe effects of climate change: the increase of severe hurricanes.

See, this kind of thing that makes me more nervous than anthropogenic warming. Assuming they could get it right(which is a big assumption) who gets to control the thermostat? Maybe the US decides their country is more productive a few degrees cooler, and Canada ends up a frozen wasteland. Maybe China has their own plans. What is the perfect global temperature, anyway?
