Antarctica conjures images of an unbroken white wilderness but blooms of algae are giving parts of the frozen continent an increasingly green tinge.

Warming temperatures due to climate change are helping the formation and spread of"green snow" and it is becoming so prolific in places that it is even visible from space, according to new research published on Wednesday .While the presence of algae in Antarctica was noted by long-ago expeditions, such as the one undertaken by British explorer Ernest Shackleton, its full extent was unknown.

"We now have a baseline of where the algal blooms are and we can see whether the blooms will start increasing as the models suggest in the future," Matt Davey of the University of Cambridge's Department of Plant Sciences told Reuters. "The algal blooms in Antarctica are equivalent to about the amount of carbon that's being omitted by 875,000 average UK petrol car journeys," Davey said."That seems a lot but in terms of the global carbon budget, it's insignificant.
