Ice core samples show West Antarctic ice sheet survived the last interglacial event
- An international team of Earth and environmental scientists found that the Ronne Ice Shelf in West Antarctica survived the last interglacial event, indicating it could withstand modern climate change.
- The researchers drilled an ice core down to bedrock at Skytrain Ice Rise, finding sea salt concentrations similar to other parts of the shelf, suggesting minimal melting.
- Isotope tests showed no significant melting of the Ronne Ice Shelf, supporting the idea that it is unlikely to melt under current conditions.
- However, the researchers warned that warmer ocean temperatures today could lead to melting below the surface, potentially affecting future outcomes.
