These graphs show carbon dioxide’s increasing greenhouse effect at two locations on the Earth’s surface, in Oklahoma and on the North Slope of Alaska; as the atmospheric concentration of CO2 (blue) increased from 2000 to the end of 2010, so did surface radiative forcing due to CO2 (orange), and both quantities have upward trends; this means the Earth absorbed more energy from solar radiation than it emitted as heat back to space.
