Our paper is out today in @aguadvances.bsky.social 🥳! My coauthors and I use a simulation spanning the Last Interglacial (~130,000 - ~115,000 years ago) to show how changes in Earth's orbit impact atmospheric river behavior and the ensuing impacts on the Greenland ice sheet. 🧪🥼⚒️❄️

Understanding what happens to Antarctica’s ice matters, because as it melts, sea levels rise, affecting lives and economies around the world.
