Stockpiling carbon dioxide in plants and soil may be effective only for the short term, if at all
If greenhouse gases are headaches for those who fear global warming, then carbon dioxide is the mother-of-all-migraines. Although other gases actually are better absorbers of Earth-warming infrared radiation, carbon dioxide has the greatest effect because it is by far the most prevalent greenhouse gas in the atmosphere.
Carbon dioxide is a natural by-product of practically everything—fossil fuel combustion, volcanoes, rotting vegetation, breathing—and its concentration in the atmosphere has been on the rise since the beginning of the Industrial Revolution. This has spurred many scientists and environmentalists to call for cuts
