Figure 6-3b for Sean Mewhinney's Minds in Ablation

Figure 6-3b

From the top down, the first and third curves show carbon dioxide and methane in the air enclosed in the ice core from Vostok, Antarctica. The second curve represents changes in temperature at the top of the inversion layer over Vostok as deduced from isotope ratios of the ice. The curve at the bottom shows oxygen-isotope ratios in a marine sediment core.
