Abstract (AI)
Abstract. The early Eocene (56 to 48 million years ago) is inferred to have been the most recent time that Earth's atmospheric CO2 concentrations exceeded 1000 ppm. Global mean temperatures were also substantially warmer than those of the present day. As such, the study of early Eocene climate provides insight into how a super-warm Earth system behaves and offers an opportunity to evaluate climate models under conditions of high greenhouse gas forcing. The Deep Time Model Intercomparison Project (DeepMIP) is a systematic model–model and model–data intercomparison of three early Paleogene time slices: latest Paleocene, Paleocene–Eocene thermal maximum (PETM) and early Eocene climatic optimum (EECO). A previous article outlined the model experimental design for climate model simulations. In this article, we outline the methodologies to be used for the compilation and analysis of climate proxy data, primarily proxies for temperature and CO2. This paper establishes the protocols for a concerted and coordinated effort to compile the climate proxy records across a wide geographic range. The resulting climate “atlas” will be used to constrain and evaluate climate models for the three selected time intervals and provide insights into the mechanisms that control these warm climate states. We provide version 0.1 of this database, in anticipation that this will be expanded in subsequent publications.
Key Findings
1
DeepMIP conducts systematic model–model and model–data intercomparisons for three early Paleogene time slices: latest Paleocene, PETM, and EECO.
2
The early Eocene (56–48 Ma) had atmospheric CO2 >1000 ppm and substantially warmer global mean temperatures than present.
3
The project establishes a coordinated effort to compile climate proxy records across wide geographic ranges into a climate "atlas" to constrain and evaluate climate models.
4
This paper defines methodologies and protocols for compiling and analyzing climate proxy data, focusing on temperature and CO2 proxies.
5
Version 0.1 of the DeepMIP database is provided, intended as an initial dataset to be expanded in future publications.
