The recent very hot years could have happened by chance without global heating, but the chance would be 1 in 10,000.

Want to bet the survival of civilization on that long shot?

2016 is expected to be hotter than 2015, because of El Niño.

If this El Niño ends, subsequent years will be a little cooler for a while; however, 15 years from now, the current level of heat will be normal even without El Niño.
