English: This visualization shows the CO2 being added to Earth's atmosphere over the course of the year 2021, split into four major contributors: fossil fuels in orange, burning biomass in red, land ecosystems in green, and the ocean in blue. The dots on the surface also show how atmospheric carbon dioxide is also being absorbed by land ecosystems in green and the ocean in blue. Though the land and oceans are each carbon sinks in a global sense, individual locations can be sources at different times. For example, in this view highlighting North America and South America, during the growing season plants absorb CO2 through photosynthesis, but release much of this carbon through respiration during winter months. Some interesting features include fossil fuel emissions from the northeastern urban corridor that extends from Washington D.C. to Boston in the United States. The fast oscillation over the Amazon rainforest shows the impact of plants absorbing carbon while the sun is shining and then releasing it during nighttime hours.
