Building a library of observed air mass trajectories to study aerosol-cloud interactions

Building a library of observed air mass trajectories to study aerosol-cloud interactions

Marine low clouds, such as stratocumulus, play a central role in regulating Earth’s climate by reflecting incoming sunlight back to space. Yet these clouds are notoriously difficult to simulate and predict. One reason is that their evolution depends strongly on the surrounding atmosphere: temperature structure, moisture, winds, and aerosols all interact in complex ways. As a result, cloud response ...[Read More]

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. H ...[Read More]

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

February 6, 2026
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 ...[Read More]

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

February 5, 2026
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–a ...[Read More]

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 mech ...[Read More]

Geoscientific perspectives on global wetland systems: Between traditional knowledge and cultural heritage

Today marks World Wetlands Day, and this year, the theme is Wetlands and traditional knowledge: Celebrating cultural heritage. Each year, February 2 is a day dedicated to recognising wetlands as places that store carbon, protect water, and hold complex cultural meaning. Wetlands such as mangroves, salt marshes, seagrass beds, peatlands, and floodplains are extremely good at taking carbon out of th ...[Read More]

Extreme hourly rainfall is increasing in Italy: insights from high-resolution climate reanalysis

February 2, 2026
Image generated using ChatGPT (AI-generated image).

Intense rainfall lasting only a few hours is often enough to trigger natural hazards such as flash floods and landslides, leading to severe damage to infrastructure. These short-lived events are among the most dangerous natural hazards in the Mediterranean region, yet they are also among the hardest to study. Their small spatial scale and brief duration mean that they are often missed or underesti ...[Read More]

Probing the Solar Wind with Spacecraft Radio Occultation Signals: Chasing a Unified Method to Probe the Sun

Introduction The solar wind, a continuous outflow of charged particles from the solar corona, plays a fundamental role in shaping the heliosphere and driving space weather. Its interaction with planetary magnetospheres and atmospheres regulates magnetospheric dynamics, influences atmospheric escape, and governs space weather hazards that can affect both space- and ground-based technologies. Despit ...[Read More]
