Summary:
- Researchers from Durham University in England have discovered a bizarre spike in platinum levels in Greenland's ice cores, which could rewrite a famous climate mystery.
- The platinum spike is believed to be related to a massive climate event that occurred around 12,000 years ago, known as the Younger Dryas period, which saw a sudden cooling of the climate.
- This new finding suggests that the Younger Dryas event may have been caused by a cosmic impact, such as a meteor or comet, rather than the previously proposed gradual changes in ocean circulation or other factors.
