Miocene climatic, oceanic and tectonic changes and selected biotic developments, as summarized in this study.

On the 26the April 2021, scientists from Bolin Centre Research Area 6 (Deep Time Climates) and international collaborators launched the Miocene Temperature Portal (, which allows investigators interested in the Miocene to access and share published proxy temperature records from the marine realm. The portal is now open and ready for use.

The data portal partners recently published a review paper ( on the Miocene, a warm period 23–5 million years ago), which is the direct result of joint RA6 and RA1 activities over 2018–2020 lead by Steinthorsdottir, Coxall and de Boer.
