At the Stable Isotope Lab in Boulder, Colo., scientists are doing a lot of the same things that those CSI folks do on TV. But instead of being “crime scene investigators,” these experts are more like “cold scene investigators.” Geoscientists like lab director Jim White work primarily with one raw material : ancient ice, in…
In 1896, Svante Arrhenius published below study on the greenhouse effect, the required carbon dioxide gas concentrations for change, and temperature variations deriving from mean, and processes in the climate system which draw down CO2, and the effects of CO2 on the climate on geological times, and elaborated on possible timescales of climate change. Arrhenius estimated based on the CO2 levels at…
