This is what we know

Carbon pollution from burning fossil fuels like coal, oil, and natural gas is changing our climate and warming our planet.

It’s simple: the more carbon pollution in the air, the more the sun’s energy gets trapped as heat. Which means things keep getting hotter. In fact, the world has already gotten nearly 1°C warmer since 1880.

Warmer temperatures have real consequences for all of us—not just for polar bears. Sea levels around the world have risen nearly 20cm (7.8 inches) since 1901, swallowing entire islands and creeping closer to populated areas of great coastal cities like New York, Melbourne, and Dakar.

Plus, extreme weather events like hurricanes, floods, and droughts are becoming more frequent and intense. Witness the devastation in 2017 as Hurricane Harvey tore through the Caribbean and southern US, destroying homes and leaving millions without power for weeks and even months.
