The Antarctic Peninsula, like many polar regions, is warming faster than the global average, with extreme heat events in Antarctica becoming more common. A study which used satellite data to assess how much the Antarctic Peninsula has been “greening” in response to climate change found that the area of vegetation cover across the Peninsula increased…
