Snow changes color in Antarctica due to climate change


Antarctica combines images of an unbreakable white forest, but algae blooms are rapidly turning green in some parts of the frozen continent. Warmer temperatures due to climate change are helping in the creation and propagation of green ice and according to new research published on Wednesday, it is becoming so prevalent in places that it is visible from space as well. While the presence of algae in Antarctica was noted by long-ago expeditions, such as those made by the British explorer Ernest Shackleton, its entire extent was ignorant. Was.

A research team from the University of Cambridge and the British Antarctic Survey, with on-the-ground observations using data collected over two years by the European Space Agency's Sentinel 2 satellite, produced the first algae blossom Map is created. Antarctic peninsula coast right there. Matt Dewey of the University of Cambridge University of Plant Sciences told Reuters. 

Moss and lichen are considered to be the major photosynthetic organisms in Antarctica – but the new mapping found 1,679 different algal blooms that are a key component in the ability to capture carbon dioxide from the continent's atmosphere. While Davy said, Algal blooms in Antarctica equate to the amount of carbon being released by an average UK petrol car trip of 875,000. It sounds a lot, but in terms of the global carbon budget, it is very insignificant. It takes carbon from the atmosphere, but it will not make any serious dent in the amount of carbon dioxide in the atmosphere at this time. Green is not just a splash in Antarctica. Researchers are now planning similar studies on red and orange algae, currently proving difficult to map from space.
