Hold on—spraying stuff into the atmosphere to cool down the planet? Have we really thought this one through? Some people are pushing these geoengineering schemes like it's no big deal, but here's the thing: what if we overshoot? The last problem we need is triggering a cooling spiral. Earth getting colder isn't some minor inconvenience—it's a potential catastrophe. Before anyone starts messing with atmospheric chemistry on a planetary scale, maybe we should run a few more simulations. Or a thousand. Porque uma vez que começamos a mexer com o céu, não há botão de desfazer.
