Summary

Story summary

A study published in Frontiers in Environmental Science warns that keeping warming below 2°C is essential to protect the Antarctic Peninsula’s ecosystems.
Under a low-emissions scenario, the peninsula could warm about 2.28°C by 2100, risking ice-shelf collapse and species extinction.
The study outlines three warming scenarios, with higher emissions causing more drastic changes, including a potential 4.4°C rise, and notes the peninsula as an early warning for broader Antarctic shifts.
