Special Issue Information
Dear Colleagues,
Throughout Earth’s history, extreme warming events—known as hyperthermals—have reshaped climate patterns, disrupted ecosystems, and altered global carbon cycles. The Mesozoic–Palaeogene era was marked by a series of these profound climate shifts, including the Permian–Triassic Boundary Event, Carnian Pluvial Event, Triassic–Jurassic Boundary Event, Jurassic and Cretaceous Oceanic Anoxic Events, and the Paleocene–Eocene Thermal Maximum. These episodes, driven by rapid CO₂ fluctuations and environmental stressors, provide a powerful lens through which we can examine the forces that govern climate stability and change.
This Special Issue, launched in conjunction with the International Workshop on Mesozoic–Palaeogene Hyperthermal Events (https://es.nju.edu.cn/igcp739/main.htm), seeks to unite leading research on these critical intervals in Earth’s past. We welcome contributions that examine stratigraphic and sedimentological records, geochemical and isotopic proxies, paleoclimate reconstructions, and the biotic responses to hyperthermal-driven environmental transformations. Studies employing Earth system modeling and deep-time data assimilation are also encouraged in order to uncover broader climate feedback mechanisms.
Key topics for submission include, but are not limited to, the following:
- Long-term climatic and environmental shifts in a greenhouse world;
- Climate and environmental changes during hyperthermal events;
- Biotic and carbonate platform responses to hyperthermal events;
- Carbon cycling and triggers for hyperthermal events.
By studying past hyperthermals, we can gain invaluable insights into Earth’s climate system—its resilience, vulnerabilities, and the thresholds that define planetary change. We invite original research articles, reviews, and case studies that contribute to this evolving and urgent field of study.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Geosciences is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
