A misleading bar chart comparing modern carbon dioxide (CO2) levels to those millions of years before humans existed ignores a large CO2 increase during the human era that has changed the climate ...Global atmospheric carbon dioxide concentrations (CO 2) in parts per million (ppm) for the past 800,000 years.The peaks and valleys track ice ages (low CO 2) and warmer interglacials (higher CO 2).During these cycles, CO 2 was never higher than 300 ppm. On the geologic time scale, the increase (orange dashed line) looks virtually instantaneous.Expanded sea ice also covers up regions of the ocean where upwelling helps bring deep-ocean CO2 back up to the surface, limiting the amount of CO2 that can be released from the oceans back into the atmosphere. Changes to ocean circulation driven by winds, evaporation and salinity also play a role in the reduction of CO2 associated with the onset of glaciation.The process begins with ultraviolet (UV) light from the sun striking a molecule of carbon dioxide in the upper atmosphere, splitting it into carbon monoxide and oxygen. Then, UV light hits the carbon monoxide and splits it into carbon and oxygen. Some carbon atoms produced this way have enough energy to escape from the atmosphere, and the new ...
