研究没有发现西伯利亚和美国的古老小行星撞击对气候的长期影响。 Study finds no long-term climate impact from ancient asteroid impacts in Siberia and U.S.

UCL研究人员的一项新研究发现,在西伯利亚造成波皮盖火山口的两次大规模小行星撞击和大约3,565万年前在美国造成切萨皮克湾火山口的两次大规模小行星撞击并未造成任何长期气候变化。 A new study by UCL researchers found that two massive asteroid impacts, which created the Popigai crater in Siberia and the Chesapeake Bay crater in the US around 35.65 million years ago, did not cause any long-term climate changes. 研究人员分析了小型海洋生物的化石,发现在接下来的150 000年中,气候没有发生重大变化。 The researchers analyzed fossils of tiny marine organisms and found no significant climate shifts over the following 150,000 years.
