Great summary of our recent paper on sea level rise during a past warm period and what it means for our future. Thanks, @climateages.bsky.social , for featuring our work.
120,000 years ago, sea levels didn’t just rise
they surged, paused, and dropped in rapid pulses.
Fossil corals recorded it all.
What they reveal could change how we think about our future coastlines.
