This figure shows the temperature record from the Vostock ice core (dark blue), together with CO2 (red) from the Vostock ice core, the Law Dome ice core, and from the Mauna Loa monitoring station in Hawaii. The dramatic increase in CO2 since the start of the industrial revolution is evident.
Vostock data are available from http://www.ngdc.noaa.gov/paleo/icecore/antarctica/vostok/vostok.html, Law Dome ice data are available from http://www.ngdc.noaa.gov/paleo/icecore/antarctica/law/law.html, and Mauna Loa data are available from http://cdiac.esd.ornl.gov/trends/co2/sio-mlo.htm.
