New Study Warns Antarctic Peninsula Faces Irreversible Damage Without Rapid Emissions Cuts
Higher emissions could cause irreversible ice shelf collapse, 20% sea ice loss, and major impacts on native species, researchers warn in modeling study.
- On February 20, Professor Bethan Davies and an international research team published a Frontiers in Environmental Science study warning of severe Antarctic Peninsula impacts if emissions continue.
- Researchers modelled three emissions pathways—low‑emissions , medium‑high , and very high by 2100—using CMIP6 climate models and eight environmental aspects to reduce uncertainty.
- Under the very high‑emissions scenario, days above 0 degrees Celsius could rise from 19 to 48, and sea ice coverage would reduce by 20 percent, while warmer oceans erode ice shelves and reduce krill, harming penguins.
- Triggering marine ice sheet instability would make many changes irreversible, with sea level rise up to 116 millimeters and roughly six million people exposed per centimetre of sea level rise.
- Humanity’s choices over the next decade are critical, and acting quickly to curb emissions could protect the Antarctic Peninsula under a low‑emissions pathway limiting warming to no more than 3.24°F.
