The Atlantic Meridional Overturning Circulation — the AMOC — has become one of the most discussed elements of the climate system. It is often portrayed as a looming tipping point, a potential disruptor of European climate, and a symbol of the uncertainties that still surround climate projections. We spoke with Didier Swingedouw, a leading researcher in ocean–climate interactions from the CNRS and ...[Read More]
ECS Spotlight: When “Day Zero Drought” Dries the Tap: How Drought is Reshaping Water Scarcity in the Anthropocene
Spatial distribution of the decadal ToFE of DZD events across the globe from 1900 to 2100. Colored shading indicates the first decade during which DZD becomes statistically attributable to anthropogenic climate change, defined as the first decade in which the Fraction of Attributable Risk is greater than 0.99 (FAR ≥ 0.99). Gray regions indicate grid cells where no DZD event attributable to anthropogenic climate change is projected to emerge before 2100. For regions with reservoirs, the ToFE is considered to be the first decade after the year of completion of their respective reservoirs, when all DZD criteria are simultaneously met. By aligning the emergence timing with the operational onset of water storage infrastructure to reflect the real-world system resilience dynamics. The black stars denote the locations of the reservoirs threatened by DZD emergence.
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]
New Editorial Voices at NPG
As part of welcoming new members to the editorial team of Nonlinear Processes in Geophysics (NPG), we are pleased to present short interviews with two newly appointed editors, Dr. Kira Rehfeld and Dr. Jezabel Curbelo. They share their scientific backgrounds, motivations for joining the journal, editorial goals, and perspectives on emerging research directions in nonlinear geosciences. Their insigh ...[Read More]
Turbulence (and not only): The Legacy of Vincenzo Carbone, 2025 Richardson Medal
One year ago, Vincenzo Carbone left us. Vincenzo was a leading scientist in nonlinear geophysics, turbulence, and complex systems, influencing fluid and plasma physics, weather and space weather, solar–terrestrial relations, and climate dynamics. Yet for those who worked closely with him, his legacy goes well beyond his remarkable scientific achievements. Scientific Contributions and Impact Over m ...[Read More]
