"Octopus Genomics Unveil Antarctic Ice Sheet Collapse and Rising Sea Level Warnings"

A study of octopus DNA has provided evidence that the West Antarctic ice sheet collapsed more than 100,000 years ago during the Last Interglacial period, confirming a long-standing geological mystery. By analyzing the genetic history of the Turquet's octopus, researchers were able to trace past encounters and determine when different populations interbred. The findings suggest that the collapse of the ice sheet occurred during a time when global temperatures were similar to today's, providing valuable information about future sea level rise in a warming climate. The study highlights the potential of using DNA as a proxy to explore other poorly understood climate histories.

Unveiling an Ice-Free Ocean: Plankton's Testimony

Analysis of microfossil content in sediment cores suggests that the Arctic Ocean was seasonally ice-free during the Last Interglacial period, between 129,000 and 115,000 years ago. Researchers found evidence of a subpolar species expanding far into the Arctic Ocean, indicating the absence of summer sea ice. This finding is concerning as it suggests that even a small increase in global temperatures, comparable to the targets of the Paris Agreement, could lead to a significant rise in sea levels. Further research is needed to understand the conditions of the Last Interglacial and its implications for the current climate crisis.
