Earths history extends back for 4.5 billion year. For the last tens of thousands of years in the Holocene era, the atmosphere has been stable with a steady content of CO2. This common gas is incredibly important for life (plants) and as a thermo-regulator for our world. If the concentration of CO2 in our atmosphere rises, global temperature rises. If it falls far enough, the planet cools enough to bring about ice ages. These processes normally take millions of years. Technically we are still in the Holocene however. Plants are also incredibly important for our world. They absorb CO2 and release Oxygen. In the Anthropocene we have inadvertently taken control…
