Scientists have calculated the amount of carbon dioxide the world can emit while limiting warming to the internationally agreed upon goals of 1.5°C-2°C. This amount is our “carbon budget.” We're on track to exceed it in little more than a decade.

Countries around the world agreed to limit global temperature rise to 1.5˚C-2˚C. A new IPCC report finds that the half-degree difference matters—a lot.

If tropical deforestation were a country, it would rank third in global emissions behind China and the United States. Tree cover loss is on the rise, but channeling climate mitigation finance towards forests could change the course of the world's climate.
