Antarctic 'greening' at dramatic rate, satellite data show

Vegetation cover across the Antarctic Peninsula has increased more than 10-fold over the last four decades, new research shows.

The Antarctic Peninsula, like many polar regions, is warming faster than the global average, with extreme heat events in Antarctica becoming more common.

The new study—by the universities of Exeter and Hertfordshire, and the British Antarctic Survey—used satellite data to assess how much the Antarctic Peninsula has been "greening" in response to climate change.

It found that the area of vegetation cover across the Peninsula increased from less than one square kilometer in 1986 to almost 12 square kilometers by 2021.
