I don't want to live in a future where the climate is radically altered. Some people have suggested pumping aerosols into the upper atmosphere to cool the globe and counteract warming from greenhouse gas emissions. But what if the treatment is worse than the problem?

A new study claims that atmospheric particle injection could have a severe side effect: major droughts in the tropics. I'd rather see greenhouse gas emissions reduced quickly. Surely it's better to avoid the problem altogether than use risky solutions.
