Here’s Figure 2-3 from Cold Cash, Cool Climate, updated to include CO2 concentrations through 2012. It shows historical carbon dioxide concentrations for the past 450,000 years, including the strikingly rapid increase since the 1800s. The early historical data come from the Vostok and Lawdome ice cores, while the more recent data (post 1959) come from direct measurements. We’ve pushed carbon dioxide concentrations well outside the range that has prevailed over the past 450 millennia.
