Global warming has had a significant impact on the climate, and the Antarctic has suddenly appeared “green snow”. According tomedia CNET, “green snow” grows in ‘warmer’ areas, with average temperatures just above zero degrees Celsius in the southern hemisphere summer from November to February, and nearby penguin colonies appear to play a role in the seaweed population. Penguin faeces can cause scientists a laughing gas problem. It can also contribute to the growth of algae.
Climate change seems to play a role in the casual “greening” of Antarctic snow. “As Antarctica warms, we predict that the overall mass of snow algae will increase, as the number of snow algae that spread to higher places will significantly exceed the loss of small pieces of algae on the island,” said Andrew Gray, a plant scientist at the University of Cambridge and lead author of the paper.
Scientists see more than just green. Parts of Antarctica look like a rainbow. The researchers plan to expand the study to red and orange algae, which contribute to this multicolored landscape.
