Vegetation on the northern Antarctic Peninsula reportedly expanded by more than 1,000% over 35 years

A post describing the study says satellite imagery shows vegetation grew from less than 1 square kilometer in 1986 to nearly 12 in 2021.

TLDR

A post describing research by the University of Exeter, the University of Hertfordshire and the British Antarctic Survey says vegetation, mostly mosses, spread across the northern Antarctic Peninsula between 1986 and 2021. It links the change to climate warming and says growing moss could alter soil conditions, while newly available habitat could help non-native species establish.

ScienceKonek@sciencekonek#SciNews 𝗔𝗡𝗧𝗔𝗥𝗖𝗧𝗜𝗖𝗔 𝗜𝗦 𝗧𝗨𝗥𝗡𝗜𝗡𝗚 𝗚𝗥𝗘𝗘𝗡 𝗗𝗨𝗘 𝗧𝗢 𝗖𝗟𝗜𝗠𝗔𝗧𝗘 𝗖𝗛𝗔𝗡𝗚𝗘 Antarctica is known for its vast ice, but parts of the frozen continent are becoming noticeably greener. A new study found that vegetation across the northern Antarctic Peninsula expanded by more than 1,000% in just 35 years, reflecting how a warming climate is reshaping even the planet’s most remote environments. Researchers from the University of Exeter, the University of Hertfordshire, and the British Antarctic Survey examined satellite imagery of the region from 1986 to 2021. In 1986, vegetation covered less than 1 square kilometer of the Antarctic Peninsula. By 2021, that area had expanded to nearly 12 square kilometers—a dramatic increase in plant-covered land across a region once dominated almost entirely by ice and bare rock. Most of this vegetation consists of mosses, which can survive in Antarctica’s harsh conditions. While small, these plants can have significant ecological effects. As moss grows and decomposes, it can contribute organic matter to the soil, potentially creating conditions where other plants can establish. This “greening” does not mean Antarctica is becoming a lush landscape. Instead, it is a warning sign of rapid environmental change. Scientists are also concerned that newly available habitats could make it easier for non-native species to establish, potentially introduced through human activity. The findings highlight an important reality: climate change is not only melting ice. It is also altering ecosystems, even in places once considered too extreme for significant plant growth. #antarctica #climatechange #green3h
