Coupled with report of ‘unstoppable’ glacial melt in Antarctica, experts say oceans rising faster than once predicted Greenland’s glaciers are far more vulnerable to climate change-induced warming oceans than previously thought, a report released Sunday by UC- Irvine and NASA glaciologists said. The study, published in the journal Nature Geoscience, reveals previously uncharted deep valleys stretching for dozens of miles under the Greenland Ice Sheet — showing that there are no natural barriers to stop the melting. The findings echo a report released last week showing that glacial melting in West Antarctica is now “unstoppable” due to topographical conditions that, similarly, will not slow the glaciers’ retreat. Bedrock canyons in Greenland sit well below sea level, which means that warming ocean waters will erode the ice much further than had been previously assumed. This could mean the melting will have a much more significant effect on global sea level […]
