- New research indicates that a mysterious platinum spike found in Greenland's ice, previously linked to a catastrophic comet or asteroid strike 12,800 years ago, was actually caused by volcanic eruptions.
- This finding re-evaluates the trigger for the Younger Dryas cooling period, a dramatic cold snap that occurred as the planet was emerging from the last ice age.
- According to SSBCrack News, new analyses point towards a "more terrestrial explanation, specifically a volcanic fissure eruption in Iceland".
- The study found that the platinum signal appeared approximately 45 years after the onset of the Younger Dryas cooling, ruling out an impact event as the initial trigger.
- As reported by The Independent, the elevated platinum concentrations lasted for 14 years, suggesting a prolonged volcanic event rather than an instantaneous impact.
- ScienceDaily notes that scientists found the platinum signal "doesn't match space debris" and its delayed appearance makes an impact unlikely to be the trigger.
Volcanoes, Not Comets, Caused Ice Age Chill
New research reveals that a mysterious platinum spike in Greenland's ice, once thought to be from a catastrophic cosmic impact 12,800 years ago, actually originated from prolonged volcanic eruptions in Iceland. This discovery fundamentally re-evaluates the initial trigger for the Younger Dryas cooling period, as the platinum signal appeared decades *after* the cold snap began, disproving an extraterrestrial cause.
