Carbon dating and pollution dating online man seeking ru

The radiocarbon dating method is based on certain assumptions on the global concentration of carbon 14 at any given time.

Mixing and exchanges happen between the atmosphere and the biosphere until such time that equilibrium is established.

Radiocarbon dating rests heavily on this assumption such that other sources of carbon 14 had, at first, not been considered nor accounted for.

Ice core records provide the most direct and detailed way to investigate past climate and atmospheric conditions.

Snowfall that collects on glaciers each year captures atmospheric concentrations of dust, sea-salts, ash, gas bubbles and human pollutants.

Ice cores provide excellent seasonal markers allowing very accurate dating.

Seasonal markers such as stable isotope ratios of water vary depending on temperature and can reveal warmer and colder periods of the year.

The government sets the cap across a given industry, or ideally the whole economy. Carbon dioxide and related pollutants that drive global warming are main targets of such caps.

Other pollutants that contribute to smog can also be capped.

Current investigations are directed toward the carbonaceous gases and the application of the accelerator technique for the assay of radiocarbon in individual chemical fractions containing microgram quantities of carbon.
