New Theory of 30 Years of Cold, Darkness Killed Off Dinosaurs

Scientists have a new theory of how when a gigantic asteroid crashed into Earth 66 million years ago, the collision lead to a "curtain" of sulfate molecules that blocked out the sun's light and warmth for decades which accelerated the demise of the dinosaurs, according to CBS News. The new findings show how these aerosols of sulfuric acid formed in the atmosphere and blocked the sunlight for 30 years which directly contributed to the deaths of 75 percent of all animals on earth.“The big chill following the impact of the asteroid that formed the Chicxulub crater in Mexico is a turning point in Earth history,” the study’s lead researcher Julia Brugger, a climate scientist at the Potsdam...
