See video of Yekaterina Nekrasova 40, swim an 85-meter distance beneath the ice of Lake Baikal. Nekrasova beat the current under-ice swim record of 70 meters set by South African Amber Fillary in Norway last year.
The rapidly warming temperature, due to global warming, is threatening Lake Baikal's fish and other aquatic species.
