“It has been suggested that debris thrown into the atmosphere in an impact tipped the Earth into global cooling at a rate as rapid as the global changes in climate in the reverse direction seen in the last century.”
I call a greentard BS alert.
I read somewhere that we get a major hit about once every 10,000 years (on average) and that is has been almost 13,000 since the last major one
All these recent hits have me a bit worried- we could be going through a ‘patch’ of space that has a bunch- we DID just cross the galactic plane, after all.
