Scientists have announced that a river in northern Canada has been dramatically re-routed due to the effects of global warming. Meltwater from the Yukon territory’s Kaskawulsh glacier, formerly flowing north into the Yukon River via the Slims River, now flows south into the Alsek River, emptying into the Pacific Ocean. The event underscores how rapidly potential changes can happen when systems that are affected by climate change reach their tipping points.

Previous estimates pegged the amount of ice loss between 2003 and 2013 at 2,500 billion tons, but the new study corrects this to 2,700 billion tons — a major factor in estimating the rate of future sea level rise.
