A new climate modeling study published in the journal Science Advances by researchers from the IBS Center for Climate Physics (ICCP) at Pusan National University in South Korea presents a new scenario of how climate and life on our planet would change in response to a potential future strike of a medium-sized (~500 m) asteroid.

Near-Earth asteroids have long been a concern for scientists studying planetary threats. As of September 2024, more than 35,800 such objects have been identified. Among them, nearly 5,000 range from 300 meters to 1 kilometer in diameter.
