Geology-Driven Catastrophe: How Chicxulub Turned a Space Rock into a Global Climate Crisis
TL;DR
A 10-km asteroid hit the Yucatán 66 million years ago, vaporising sulfur-rich rocks beneath it and lofting sulfur-bearing gases and dust into the atmosphere; the impact angle and local geology amplified the effect, triggering global cooling and a mass extinction, though the exact atmospheric recipe is still being refined by researchers.
