Mysterious giant hole in Siberia likely caused by global warming, not UFOs or meteors.

A mysterious giant hole has appeared in northern Siberia, prompting wild speculation about meteors, UFOs, and underground cities.

The likely explanation is less supernatural, scientists say, but no less extraordinary.

The Siberian Times reported the hole – which is more than 260 feet across and of unknown depth – was spotted from helicopters flying over the gas-rich Yamal Peninsula.

Dr. Chris Fogwill, a polar scientist from the University of New South Wales, said the crater was most likely caused by a geological phenomenon called a pingo.

A pingo is a block of ice that forms under frozen arctic hillsides that can eventually push through the earth and leave an exposed crater once it melts away.
