Researchers reported that due to global warming, melt every year water will have a stronger effect on the ice cover. So, for example, in 2018, most likely, appeared in the ice of Greenland the largest waterfall in the world. This was reported Washington Post Newsletter.

This waterfall took only five hours to empty meltwater lake, which measures 5,000,000 cubic meters meters, which is approximately equal to 2000 Olympic pools. This phenomenon very worried scientists. To carefully study this anomaly, researchers used drones. Research results published in the Proceedings of the National Academy of Sciences.
Greenland’s ice cover is about 1 thick kilometers. In the summer season, surface ice melts, in As a result, huge lakes of meltwater are formed. After for some time, water begins to flow out of them, forming huge – almost kilometer voids. Water in these places in further begins to drain intensively, creating the highest waterfalls in the world.
Scientists are sure that many representatives of the scientific community underestimate the magnitude of this phenomenon, when huge masses of melt water in a short period of time fall into the sea.
Researchers have created a computer model of this phenomenon and realized that it is necessary to change the previous forecasts of increase in level seas. If previously the UN reported that meltwater can not provide a strong influence on the movement of the ice sheet, then work researchers completely refutes this statement.

Experts are sure that every year climate processes changes are accelerating, and similar lakes with powerful waterfalls will be more and more.
Scientists also found out another controversial issue in the occurrence of huge waterfalls. It turned out that the water from the resulting reservoirs begins to leave them through cracks and not into overflow result. This suggests that melt water is leaving under the ice sheet, which thanks to this comes in motion and begins to slide.
