The visualizations show the carbon dioxide added to the Earth in 2021 as colorful smoke above the surface. In blue and green is the amount released by land ecosystems, plants and wild animals, and oceans. In red is the burning of biomass. And in orange is the release of fossil fuels. Flashing in green and blue are the places on the planet where carbon is absorbed: forests and oceans. The flashing rhythm depends on whether it’s day or night, and on the season.
