According to a recent study, it is predicted that if global warming continues at the current rate, all the blue lakes in the world face the threat of turning green brown in colour. Various factors including elevation, depth of the lake, air temperature, algae and sediments determine the colour of a lake.
According to scientists, the increase in the temperature of water gives rise to more algal blooms, making the water of lakes greener and changing its quality. Various lakes around the world, including lakes in remote Arctic regions, have turned greenish due to an increase in algal blooms.
