WASHINGTON — A group of Swedish researchers believe that a cataclysmic asteroid collision from hundreds of millions of years ago could have the answers to solving climate change.
The international study examines the aftermath after a huge asteroid was crushed between Jupiter and Mars sending large amounts of dust through the solar system. The dust had a "blocking effect" on sunlight reaching Earth, causing an ice age and creating climate zones on Earth. Before this, the Earth is said to have had a more homogeneous environment.
Researchers have been discussing different artificial methods of recreating post-collision asteroid dust, such as placing asteroids in orbits around Earth like satellites and having them "liberate fine dust" to block warming sunlight, thus hypothetically cooling our warming planet.
