Global warming is a hipster way of saying “pollution”. It’s like calling your Chevrolet your “wheels” - there’s more to the car than just the wheels, and if you took the wheels off and put on Armstead screw drives, it’s still be a Chevrolet, despite having no wheels.
Pollution is a root problem; a cause that people can individually address, and “global warming” is a metric, an average of globally distributed symptoms that is useful to climatologists and polemicists who want to manipulate you.
By contrast, celestial objects threatening the Earth are a real issue - not just an attenuated metric - but also not something individuals can do something about. But y’know, it occurs to me that if we could all come together enough to actually beat pollution, maybe we’d be co-operating well enough to start trying to avert incoming meteors.
