OpenThe world's green
How many trees we lose and why, the tropics' primary forests, the carbon forests absorb and release.
OpenCorrelation lab
Pick two global series and check whether they move together. With an honest explanation of what that means.
OpenHow we work
Open sources only
NASA, NOAA, Global Carbon Project, Global Forest Watch, FAO, World Bank, Ember, Energy Institute. Every chart says where its data come from and up to which year.
No invented numbers
Values are downloaded unchanged, only converted between units. When a figure is our own calculation, it says so next to it, with the method.
Correlation is not causation
The lab shows when two series move together and when they do not, and explains what science knows about the link between them.
Updated every month
An automated process checks the sources every month. When a new year is published, the charts update.
These pages were built with the help of an artificial intelligence assistant. Every page states its sources and how calculations are made, so that everything can be checked.
