For the first time, it is now possible to measure, simultaneously and with extreme precision, four rare molecular variants of carbon dioxide (CO2) using a novel laser instrument. It is thus able to measure the temperature during the formation of CO2-binding carbonates and carbonaceous fossils completely independently of other parameters. As a new type of geothermometer, the laser-spectroscopy-based measurement device is significant for scientific disciplines investigating, for example, climatic conditions in Earth's history. It was developed by a German-French research team, with substantial contributions from environmental physicists at Heidelberg University.
