Sorry, what? In 2006, National Geographic posted that, "Even a small nuclear conflict would cause long-lasting global devastation that could kill tens of millions, scientists warned this week."
Then last week, they posted that, "Even a regional nuclear war could spark "unprecedented" global cooling"
Sorry, what? Is global warming such a concern that 'long lasting global devastation' is a reasonable risk?
Hat tip to FerFal for the pointer.
