UN: Global Warming Happening Faster Than Predicted

The World Meteorological Organization says the first half of this year has been the hottest in history - a sign that global warming is happening faster than expected. The U.N. organization based in Geneva warned Thursday that 2016 is on track to be the world’s hottest year on record. Zlatica Hoke reports the WMO called on signatories to start implementing the climate agreement reached last year in Paris as soon as possible.
