A Record-Breaking Indian Ocean Dipole: What Happened in 2021–2022?

The Indian Ocean Dipole (IOD) is generally considered a seasonal mode of variability, developing and decaying within a single year. During 2021–2022, however, negative IOD conditions persisted for approximately 19 months (Figure 1, top left), making this event the longest—and among the strongest—observed since reliable records began. This unusual persistence highlights important aspects of ocean–atmosphere coupling and raises new questions for climate predictability in a warming world. Published in Weather and Climate Dynamics, we document this extraordinary climate event in …


The courage to be disliked: reflections on peer-review processes

Although often daunting and discouraging, every academic must navigate the inevitable process of peer review. In this week’s post, Jean-Baptiste Koehl, postdoctoral researcher at the University of Oslo (Norway), reflects on what the future of peer review might be. Author disclaimer: The reflections presented here reflect my perspective grounded in my own experience. While peer review is a key mechanism which we rely on to ensure the quality and integrity of scientific research, it has flaws and can perpetuate power …


Highlighting: Fluvial Biogeomorphology! (Interview with Florian Betz)

This blog post is part of our series: “Highlights” for which we’re accepting contributions! Please contact Emma Lodes (GM blog editor, elodes@asu.edu), if you’d like to contribute on this topic or others. by Florian Betz, Principal Investigator at the Earth Observation Research Cluster at University of Würzburg. Email: florian.betz@uni-wuerzburg.de What is biogeomorphology and why is it important? Biogeomorphology is the study of the interaction between ecologic and geomorphic processes. This can be small-scale processes such as biologic micro-crusts influencing rock …
