☆ Asteroid that doomed the dinosaurs halted key process for life on Earth, scientists say

This dust blocked the sun to an extent that plants were unable to photosynthesize, a biological process critical for life, for almost two years afterward. Pim KaskesAn unexpected killing mechanismTo reach their findings, scientists developed a new computer model to simulate the global climate after the asteroid strike. Fossilized fish found at the site have revealed that the asteroid struck off Mexico’s Yucatán Peninsula in springtime. The team determined that this fine dust could have remained in the atmosphere for up to 15 years after the asteroid strike. The researchers suggested the global climate may have cooled by as much as 15 degrees Celsius.

☆ Dinosaur-killing asteroid impact fouled Earth's atmosphere with dust
  + stars: | 2023-10-30 | by ( Will Dunham | ) www.reuters.com   time to read: +5 min
The total amount of dust, they calculated, was about 2,000 gigatonnes - exceeding 11 times the weight of Mt. While prior research highlighted two other factors - sulfur released after the impact and soot from the wildfires - this study indicated dust played a larger role than previously known. "It was cold and dark for years," Vrije Universiteit Brussel planetary scientist and study co-author Philippe Claeys said. "While the sulfur stayed about eight to nine years, soot and silicate dust resided in the atmosphere for about 15 years after the impact. "Without the impact, my guess is that mammals - including us - had little chance to become the dominant organisms on this planet."
