CYCLIM: cycle counting a faster way

As we try to predict what will happen under increasing anthropogenic climate change, climate models can only get us so far. Another key is understanding past changes in the Earth’s climate. To do this, palaeoclimatologists turn to natural archives (e.g., sediment cores and speleothems) and extract records of past variability using their properties, such as chemical or physical composition. However, these reconstructions are only as accurate as their chronologies. While radiometric dating is the most common technique, some archives can …


GeoTalk: Meet Soil Microbiologist and Early Career Scientist Biogeosceinces Representative, Elsa Abs!

Hello Elsa & welcome to GeoTalk! Before we dig deeper, could you introduce yourself to our readers? Hi! I’m Elsa (they/them). I’m a microbiologist/biogeochemist, and I just started a permanent position at the French National Centre for Scientific Research (CNRS) one month ago. I work with one PhD student, Elisa Richard, and two postdocs, Mathilde Bourreau and Thomas Cortier, on my ERC Starting Grant project called GAMEchange. We investigate how the genetic evolution of soil microbes impacts future projections of …


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 …
