This week, world leaders are converging in Paris to talk about climate policy. Under current guidelines, the planet is on target to warm by 2 degrees Celsius in 2050 and by 4 degrees in 2100, triggering serious large-scale problems by the end of the century.

Ramanathan, who will be speaking at the conference, accurately predicted this trend back in 1980. In the video above, he explains how we might be able to change our course on climate.
