Thousands of Russians celebrating the Orthodox Christian feast day of Epiphany, where worshippers bathe in the icy waters of frozen lakes and rivers, have been forced to cancel their traditional ceremonies due to unusually warm winter temperatures.

Across Russia, the devout celebrate Epiphany on January 19 by immersing themselves in frigid water through holes cut through the ice of lakes and rivers, imitating the baptism of Jesus Christ in the River Jordan.

Climate change is threatening the traditional ice-bathing of Orthodox Christians on Epiphany: In many places in Russia and Eastern Europe, the ice cover is not thick enough. But believers are not letting this stop them.
