UK's Boris Johnson warns of 'doomsday' as climate summit begins

British Prime Minister Boris Johnson warned of "doomsday" at the global climate summit held in Glasgow.

British Prime Minister Boris Johnson opened a global climate summit Monday, saying the world is strapped to a "doomsday device."

Johnson likened an ever-warming Earth's position to that of fictional secret agent James Bond - strapped to a bomb that will destroy the planet and trying to work out how to defuse it.
