Figure 6
Change in pCO2 and solar radiative forcing (ΔS[CO2,SOL]) versus mean low-latitude (0–30°) paleotemperature (ΔTLL) for 10-myr intervals in the Cenozoic (orange), Mesozoic (green), and Paleozoic (blue-green). Filled symbols identify statistically significant relations (p < 0.05). Equations show Deming Model II regression (heavy dashed lines) and simple linear regression with associated uncertainty (gray dashed line with dotted uncertainty bands). Only Paleozoic data show a significant relationship.
