By June and July 2021, plants again draw CO 2 out of the atmosphere, but notably higher concentrations remain in contrast to the nearly transparent colors of the previous year. The diurnal rhythm of CO 2 is apparent over our planet's largest forests, such as the Amazon rainforest in South America and the Congo rainforest in Central Africa. The concentration of methane in the atmosphere is currently around two-and-a-half times greater than its pre-industrial levels.

The diurnal rhythm of CO 2 is apparent over our planet's largest forests, such as the Amazon rainforest in South America and the Congo rainforest in Central Africa. The oceans cover over 70% of the Earth’s surface and play a crucial role in taking up CO2 from the atmosphere. Estimates suggest that around a quarter of CO2 emissions that human activity generates each year is absorbed by the oceans. However, in our recent Nature Communications paper, we show that the ocean carbon “sink” could …Altogether the planet absorbs and emits around 100 billion metric tons of carbon through this natural cycle every year, Rothman says. That's equivalent to over 350 billion tons of CO 2. (Scientists often measure the carbon cycle in terms of the weight of carbon atoms, not whole molecules of carbon dioxide, because the carbon has the same weight ...Global energy-related CO2 emissions grew by 0.9% or 321 Mt in 2022, reaching a new high of over 36.8 Gt.
