Imatge:CO2-Mauna-Loa.png

• Description: A graph depicting CO₂ levels from 1958 to 2006 as measured at Mauna Loa, Hawaii. Year is on the x-axis, atmospheric carbon dioxide concentration (in parts per million) is on the y-axis. The cause for the yearly rise and fall is the annual cycle of plant respiration. The cause of the increasing trend is the anthropogenic release of CO₂, mainly due to the use of fossil energy sources.
