Towards reliable reconstructions of Pliocene terrestrial temperatures using branched tetraether membrane lipids
conference paper
The Mid-Piacenzian Warm Period (mPWP, ca. 3.3-3.0 Ma) is a frequently targeted interval
for model simulations because it is considered to be an analogue for the climate of the mid-
21st century. CO2 levels, continental configurations, land elevations, and ocean bathymetry
during the mPWP were comparable to present. However, global temperatures were warmer
by 2-4 °C, indicating that current climate may not have reached equilibrium. While sea
surface temperature (SST) reconstructions for the mPWP are abundant, temperatures in the
terrestrial realm remain poorly constrained due to the scarcity of stratigraphically complete
terrestrial sedimentary archives and a lack of quantitative proxies for mean air temperature
(MAT).
