Atmospheric CO2 over the Past 66 Million Years from Marine Archives
Throughout Earth's history, CO2 is thought to have exerted a fundamental control on
environmental change. Here we review and revise CO2 reconstructions from boron isotopes …

Observational estimates of dynamic topography through space and time
M Hoggard, J Austermann, C Randel… - Mantle convection …, 2021 - Wiley Online Library
Earth's mantle undergoes convection on million‐year timescales as heat is transferred from
depth to the surface. While this flow has long been linked to the large‐scale horizontal forces …
