Oxidizable carbon ratio dating is a method of dating in archaeology and earth science that can be used to derive or estimate the age of soil and sediment samples up to 35, years old. The method is experimental, and it is not as widely used in archaeology as other chronometric methods such as radiocarbon dating. This dating method works by measuring the ratio of oxidizable carbon to organic carbon. If the sample is freshly burned there will be no oxidizable carbon because it would have all been removed by the combustion process.

Indeed, we have already seen the stark asymmetry of suffering resulting from extreme weather events, such as hurricanes, floods, droughts, wildfires and more. These proposals are, of course, essential to reducing manmade carbon emissions—71 percent of which are generated by just fossil fuel companies. For this reason, fossil-fuel—related emissions reductions rightly figure heavily in the national climate commitments of the nations that signed the global Paris Agreement.

Carbon 14 C , or radiocarbon , is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons. Its presence in organic materials is the basis of the radiocarbon dating method pioneered by Willard Libby and colleagues to date archaeological, geological and hydrogeological samples. Its existence had been suggested by Franz Kurie in
