Fig. 3: Climate forcing impact on Holocene Thermal Maximum.
From: Complex spatio-temporal structure of the Holocene Thermal Maximum

Relative sea level47; Holocene Thermal Maximum (HTM) age probability density function between 30°N and 70°N over land and ocean, and between 30°S and 30°N in the oceans. Mean annual insolation at 65°N and at the equator and the sum of radiative forcing (CO2, CH4, N2O, Volcanic emission and solar irradiance; see details in “Methods”). Orbital forcing were calculated according to refs. 48, 49 using a dedicated function50.
