Sulfur from dino-killing asteroid caused way more global cooling than thought

When the dinosaur-destroying asteroid collided with Earth 66 million years ago, massive amounts of sulfur — volumes more than were previously thought — were thrown high above land into the stratosphere, a new study finds.

Once airborne, this vast cloud of sulfur-bearing gases blocked the sun and cooled Earth for decades to centuries, then fell down as lethal acid rain on Earth, changing the chemistry of the oceans for tens of thousands of years, which is longer than previously thought, the study found.
