On the Remote Impacts of Mid‐Holocene Saharan Vegetation on South American Hydroclimate: A Modeling Intercomparison

Proxy reconstructions from the mid-Holocene (MH: 6,000 years ago) indicate an intensification of West African Monsoon and a weakening South American Monsoon, primarily resulting orbitally-driven insolation changes. However, model studies that account for MH orbital configurations greenhouse gas concentrations can only partially reproduce these Most do not remarkable vegetation changes occurred during MH, in particular over Sahara, precluding realistic simulations period. Here, we study precipitation northern Africa America using four fully coupled global climate models by accounting Saharan greening. Incorporating Green Sahara amplifies both regions, leads to improvement proxy-model agreement. Our work highlights local remote impacts importance considering when studying modeling climate.
