Sentences with phrase «global inorganic carbon»

In other words, if all of the terrestrial carbon today (in forests, animals, soils, etc.) were converted to carbon dioxide and returned to the global inorganic carbon pool, the change in the global carbon isotopic ratio would only be a third as big as that observed during the PETM!

Not exact matches

These have provided insight into the roles that marine bacteria, archaea, viruses and eukaryotic microbes have as global primary producers that provide nutrition at the base of the food chain; remineralization (the transformation of organic molecules into inorganic forms); and the deposition of carbon on the sea floor.

Using inorganic carbon measurements from an international survey effort in the 1990s and a tracer - based separation technique, we estimate a global oceanic anthropogenic carbon dioxide (CO2) sink for the period from 1800 to 1994 of 118 ± 19 petagrams of carbon.

Whilst these inorganic fluorine compounds and perfluorocarbons have large global warming potentials, which make for dramatic media headlines, their atmospheric abundances and mixing ratios are very small, and hence their contributions to radiative forcing in the atmosphere and hence to anthropogenic forcing of climate processes are very small by comparison to carbon dioxide, methane and water vapor.
