A recent study published in Science Advances highlights the potential consequences of a medium-size asteroid collision with Earth. Researchers modeled scenarios where such an asteroid strikes land, predicting catastrophic effects like tsunamis and fires. Medium-size asteroids, like Bennu—which has an estimated 1-in-2,700 chance of colliding with Earth in 2182—could cause an 'impact winter,' leading to severe reductions in solar radiation and significant declines in photosynthesis, affecting food security and habitats across the globe for years to come.
A medium-size asteroid collision could result in devastating environmental consequences, causing long-term changes to Earth's climate and severely threatening food security.
Research predicts that dust from a medium-sized asteroid impact could cause an 'impact winter,' reducing photosynthesis on land by 36% and in the oceans by 25%.
The potential collision of a medium-size asteroid like Bennu could lower solar radiation reaching Earth's surface for nearly two years, leading to drastic climatic changes.
Even though medium-sized asteroid collisions are unlikely, the potential consequences of events like a Bennu impact raise significant concerns about global food security and habitat suitability.
