ECS Spotlight: When “Day Zero Drought” Dries the Tap: How Drought is Reshaping Water Scarcity in the Anthropocene

Ravinandrasana P. Vecchia April 20, 2026

Extreme events are becoming increasingly observable, intense, and interconnected. Drought, traditionally viewed as a regional and temporary phenomenon, is now undergoing a fundamental shift. We introduce the concept of “Day Zero Drought” to describe a threshold where water demand exceeds available supply under persistent drought conditions. This study shows that water scarcity is no longer confin ...[Read More]

ECS Spotlight: Evolution of the Dynamics of Centennial Hot Summers in Western Europe With Climate Change

Robin Noyelle December 1, 2025

Extreme meteorological and climatological events can be immensely damaging and disruptive to society. Understanding the physical mechanisms driving these events, and how they will evolve with climate change is crucial for informing societal adaptation to our changing climate. However, extreme events are, by definition, rare. Our capacity to understand these events is, therefore, hindered by the sm ...[Read More]

Rethinking the carbon cost of scientific exchange: Nonlinear effects of reducing scientific mobility

Davide Faranda and Tommaso Alberti November 4, 2025

The carbon footprint of scientific collaboration has become an increasingly debated topic. Conferences, workshops, and research travel remain central to how science function, yet they also contribute to global greenhouse gas emissions. Since the pandemic era scientists also learned to work virtually and to attend workshops and conferences online. Understanding the carbon footprint, and how it comp ...[Read More]

Where is climate science heading? Views from the community

Mireia Ginesta October 15, 2025

At the recent UNDERPIN2 conference (Understanding rare events and their climatic impacts, in Erice, Sicily), we held a discussion on the future of climate science. To guide the conversation, I ran an interactive survey to capture how climate scientists see the current challenges, opportunities, and blind spots in climate research, communication, and the use of artificial intelligence. The response ...[Read More]

From Theory to Impacts: Nonlinear Perspectives on Weather Extremes at UNDERPIN#2

Meriem Krouma August 29, 2025

From 1–5 August 2025, the medieval hilltop town of Erice, Sicily, hosted the second UNDERPIN workshop, a meeting organised within the Nonlinear Processes in Geosciences community and dedicated to advancing the science of weather extremes. The event brought together a truly diverse group of researchers, spanning climate dynamics, attribution science, socio-economic impacts, statistical physics, and ...[Read More]

Mireia Ginesta April 21, 2025

Today’s NP Interviews hosts the outcoming NP Division President François Schmitt. François has a PhD degree from Université Pierre et Marie Curie in Paris (1993), in atmospheric turbulence, and an Habilitation degree from the same university (2001). He has stayed in Belgium during 6 years as a post-doc, working in meteorology and in fluid mechanics. He is CNRS researcher in Wimereux (North of Fran ...[Read More]

Interviews with Women in Nonlinear Processes in Geosciences: Exploring Inspiration and Challenges

Mireia Ginesta-Fernandez February 11, 2024

In celebration of Women in Science day, we delve into the experiences and insights of five accomplished women scientists in the field of Nonlinear Processes in Geosciences: Prof. Bérengère Dubrulle, Dr. Vera Melinda Galfi, Dr. Giorgia di Capua, Dr. Meriem Krouma, and Anupama K Xavier. Through a series of interviews, these women share their journeys, addressing challenges faced as women in science, ...[Read More]

Training the new generation of scientists to address Climate Change issues in Africa: Insights from the Marrakech-Benguerir Climate Change, Projections and Services Summer School

Davide Faranda November 10, 2023

In the ever-evolving landscape of climate change, the Université Mohammed VI Polytechnique (Buengerir, Marocco) and Institut Pierre Simon Laplace (Paris,France) Summer School has emerged as a beacon of knowledge, equipping participants with the tools to comprehend, navigate, and mitigate the impacts of a changing climate. The inaugural edition of the summer school focused on “climate change, ...[Read More]

Nonlinear Processes in Earth System Dynamics

Gabriele Messori September 27, 2023

Earth System Dynamics (ESD) is an open-access EGU journal focussing on an interdisciplinary view of the functioning of the Earth system and global change. Due its broad focus, ESD receives submissions of relevance to several different EGU divisions. Here, I would like to highlight five thought-provoking ESD papers that cover topics spanning environmental governance, extreme events, palaeo-climates ...[Read More]
