Once considered a frozen wilderness, Antarctica is now witnessing a striking transformation. Rising temperatures are melting vast expanses of ice, creating new habitats where resilient plants—most notably mosses—are taking root. At first glance, this greening may seem like a positive ecological shift. However, scientists warn that it is a troubling sign of rapid ecosystem disruption and accelerated climate change. As the white expanse recedes, the paradox emerges: new plant growth is both a symptom and a catalyst, amplifying warming and signaling the approach of critical climate tipping points.
