The agony of Earth’s hottest year

Globally, 2016 is expected to be the hottest on record — breaking the record set in 2015, which broke the record from the year before that. In all, scientists say humans have warmed the planet about 1 degree Celsius since around the time of the Industrial Revolution. This heat, which we’re causing by burning fossil fuels and trapping warmth in the atmosphere, is contributing to a host of dangerous weather around the world.
