In 140 years of direct surface measurements, only the first half of 2016 was hotter (which turned out to be the warmest year ever recorded). Already, 19 of the last 20 years are the warmest on record.

For decades, climate scientists have accurately predicted how much the climate would warm as humanity continually pumped CO2 into the atmosphere. The warming pattern persists.
"The recent data shows that the world is heating in line with predictions," Sarah Green, an environmental chemist at Michigan Technological University, told Mashable. Read more >>
