May 24. Kas lake 2 (Cachet II), located in the southern part of Patagonia, disappeared in less than 24 hours, leaving a muddy puddle. The lake holds 200 million cubic liters of water flooded into the river Baker, increasing its capacity by 3 times and emptying the area of 5 square kilometers.
Since 2008, Kas two dried out 11 times. People living in the region, are in constant danger of sudden flooding that could collapse from the mountains. Experts say that if global warming is not stopped, floods will occur more often.
Melting glaciers column is the cause of motion lakes rivers. The glacier is located 2000 kilometers south of the capital, Santiago. He often serves as a dam, but the global rise in temperature indicators weakened his "wall." Already twice in 2012 (January 27 and March 31) lake water disappeared, breaking the tunnel between the mountain and glacier. Between March drying the water level fell by 31 meters.
The drying up of the lake there was at least 53 times between 1896 and 2010, but in recent years the rate has increased markedly. The phenomenon is called "dumping ice-dammed lakes" and study section glyatsilogii known as quaternary glyatsiogidrologiya. It is observed not only in Patogonii, but in the Himalayas, Iceland and Peru.
