Climate change is turning Antarctica green, say researchers

Antarctica may conjure up an image of a pristine white landscape, but researchers say climate change is turning the continent green. Scientists studying banks of moss in Antarctica have found that the quantity of moss, and the rate of plant growth, has shot up in the past 50 years, suggesting the continent may have a verdant future.

“Antarctica is not going to become entirely green, but it will become more green than it currently is,” said Matt Amesbury, co-author of the research from the University of Exeter.

“This is linking into other processes that are happening on the Antarctic Peninsula at the moment, particularly things like glacier retreat which are freeing up new areas of ice-free land – and the mosses particularly are very effective colonisers of those new areas,” he added.

In the second half of the 20th century, the Antarctic Peninsula experienced rapid temperature increases, warming by about half a degree per decade.

Plant life on Antarctica is scarce, existing on only 0.3% of the continent, but moss, well preserved in chilly sediments, offers scientists a way of exploring how plants have responded to such changes.
