New research suggests that a platinum spike found in Greenland's ice core around 12,800 years ago, previously thought to indicate a meteorite impact, was likely caused by a volcanic fissure eruption in Iceland, which may have contributed to the climate cooling during the Younger Dryas period, rather than an extraterrestrial impact.
A mysterious platinum signature found in Greenland's ice, previously thought to indicate a space impact, is now attributed to a volcanic eruption in Iceland, which may have contributed to the onset of the Younger Dryas cold period, highlighting the role of volcanic activity in past climate shifts.
New research suggests that a platinum spike found in Greenland's ice core around 12,800 years ago, previously thought to indicate a meteorite impact, was likely caused by a volcanic fissure eruption in Iceland, which may have contributed to the onset of the Younger Dryas cold period by releasing sulfur and heavy metals into the atmosphere. This finding challenges the impact hypothesis and highlights the role of volcanic activity in past climate shifts, emphasizing the importance of understanding such events for future climate predictions.
