The Paleocene-Eocene Thermal Maximum (PETM; ca. 56Ma) is a time when global temperatures greatly increased due to rapid carbon emissions. The event is marked by a negative carbon isotope excursion (CIE) that is observed in both marine and terrestrial records. However, the amount, rate, and source of the emitted carbon remains highly debated. This study investigates the response of the eastern Tethys, an understudied subtropical shallow marine environment, and assesses the climatic impacts during the PETM. An Earth system model of intermediate complexity (cGENIE) ran six “double-inversion” experiments with δ11B and δ13Ccarb forced onto the …

The Early Eocene hyperthermals are a series of transient global warming events that occurred between 54.09 and 52.63 Ma, and are considered as ancient analogues for future climate change. These hyperthermal events are well studied in the deep sea sites, but have not been investigated in the eastern Tethys Ocean. Here, we report new major and trace element geochemistry and stable carbon isotope data of the Early Eocene strata deposited in a shallow marine foreland basin prior to the main stage of India-Asian continent collision at Qumiba section in the Tingri County, southern Tibet. These geochemical data are used to …
