Both have happened much faster than predicted by climate models, and observed Arctic ...

Among the significant events that caused a temporary but significant spike in the atmospheric carbon-14 to carbon-12 ratio were above-ground nuclear test detonations in the two decades following World War II.A detailed description of radiocarbon dating is available at the Wikipedia radiocarbon dating web page.Bottom line: Radiocarbon dating is a technique used by scientists to learn the ages of biological specimens from the distant past.Because the cosmic ray bombardment is fairly constant, there’s a near-constant level of carbon-14 to carbon-12 ratio in Earth’s atmosphere.Organisms at the base of the food chain that photosynthesize – for example, plants and algae – use the carbon in Earth’s atmosphere.
