After production in the upper atmosphere, the carbon-14 atoms react rapidly to form mostly (about 93%) CO (carbon monoxide), which subsequently oxidizes at a slower rate to form CO 2, radioactive carbon dioxide. The gas mixes rapidly and becomes evenly distributed throughout the atmosphere (the mixing timescale in the order of weeks). Carbon dioxide also dissolves in water and thus permeates the oceans, but at a slower rate. The atmospheric half-life for removal of C… WebAug 1, 2024 · This indicator describes how the levels of major greenhouse gases in the atmosphere have changed over time. Figure 1.
