Long Term View Of CO2

Many of the charts demonstrating CO2 rise show the trend since the Industrial Revolution. On such a scale, the rise is significant, but for some does not tell the long term climate story as well as looking back 400,000 years. Ice cores do show several cycles, but none are as severe as what’s happened in the last 10,000 years, and also how steep the slope has been since 1950. In March, atmospheric CO2 concentrations reached 405.6 ppm.
