Carbon Dioxide Concentrations in the Atmosphere;; A closer look at the carbon dioxide changes within the last thousand years can be seen in the graphic on the left. The concentrations of carbon dioxide in the atmosphere, were measured in the bubbles from an Antarctic ice core from Law Dome near Australia's Casey Station.

Various techniques have been proposed for removing excess carbon dioxide from the atmosphere in carbon dioxide sinks. Not all the emitted CO2 remains in the atmosphere; some is absorbed in the oceans or biosphere.

CDIAC's data holdings include records of the concentrations of carbon dioxide and other radiatively active gases in the atmosphere; ... emissions of carbon dioxide to the atmosphere; long-term climate trends; the effects of elevated carbon dioxide on vegetation; and the vulnerability of coastal areas to rising sea level.

Carbon dioxide has a very short residence time in the atmosphere. Beginning with the 7 to 10-year half-time of CO2 in the atmosphere estimated by Revelle and Seuss (69), there were 36 estimates of the atmospheric CO2 half-time based upon experimental measurements published between 1957 and 1992 (59). These range between...

While algae and other microscopic plants in the oceans are constantly removing C02 from the atmosphere as they grow and live, eventually they die and sink returning the carbon dioxide to the deep ocean.

In North America alone, humans release two billion tons (1.85 billion metric tons) of carbon as CO2 into the atmosphere each year through burning fossil fuels and manufacturing cement. Typically, forests, grasslands, ... Climate extremes can have a major effect on the amount of carbon dioxide in Earth’s atmosphere.”...
