Study Suggests Asteroid Impacts Could Trigger 'Snowball Earth' Events
New research led by Yale University explores the potential for asteroid impacts to rapidly freeze the planet, though skeptics question the lack of geological evidence.
- A new study suggests asteroid impacts could have triggered 'Snowball Earth' events, covering the planet in ice.
- The research, led by Yale University, used climate models to simulate asteroid impacts during various Earth climates.
- Findings indicate that in already cold climates, such impacts could lead to rapid global glaciation.
- Skeptics highlight the lack of geological evidence for such impacts coinciding with known glaciation periods.
- Despite the intriguing theory, the likelihood of a future 'Snowball Earth' due to asteroid impact is deemed low due to current global warming.
