Scientists solve 12,800-year-old climate mystery hidden in Greenland ice
🤖AI Özeti
A recent study has uncovered that a spike of platinum found in Greenland's ice, previously thought to indicate a comet or asteroid impact 12,800 years ago, is actually linked to volcanic eruptions. This research suggests that the cooling period known as the Younger Dryas was not triggered by an extraterrestrial event but rather by geological activity. The platinum signal was found to have appeared decades after the onset of cooling, contradicting earlier theories of a catastrophic impact.

The Younger Dryas is a period marked by a sudden return to glacial conditions after a warming trend, and its causes have been debated for years. The discovery of the platinum spike in ice cores has led to various hypotheses, primarily focusing on extraterrestrial impacts. This new research shifts the narrative towards terrestrial geological activities, emphasizing the role of volcanoes in climate change.
