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

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]

Socio-economic and security implications of global heating

This year, like in the last few years, we are experiencing the effects of global heating in increasingly personal ways. The summer of 2022 exposed us to ever more extreme heat waves in North America, Europe, and Asia. For instance, the heat wave in India and Pakistan reached temperatures of 49C in Nawabshah, Pakistan. North America too experienced devastating heat waves and wildfires. Los Angeles ...[Read More]

ClimarisQ: A game on the complexity of the climate systems and the extreme events

ClimarisQ is a smartphone/web game from a scientific mediation project that highlights the complexity of the climate system and the urgency of collective action to limit climate change. It is available in four languages: English, French, Spanish and Italian. It is an app-game where players must make decisions to limit the frequency and impacts of extreme climate events and their impacts on human s ...[Read More]

NP Campfire: “Scaling and multifractals : from historical perspectives to recent developments”

Scaling law behaviours are ubiquitous in geosciences both from a theoretical and practical point of view. They are required to better understand, analyse and simulate the underlying processes, which yields the observed variability of geophysical fields over wide ranges of spatio-temporal scales. A group of scientists within the Nonlinear Processes in Geosciences (NP) Division of the European Geosc ...[Read More]

NPG Paper of the Month: “Empirical evidence of a fluctuation theorem for the wind mechanical power input into the ocean”

This month the NPG Paper of the Month award is achieved by Achim Wirth for his paper “Empirical evidence of a fluctuation theorem for the wind mechanical power input into the ocean“. Achim obtained his PhD at the University of Nice (Franc), doing research on turbulence theory. He then moved to oceanography working at UCLA (USA) and Geomar (Germany). Since 2005 he holds a permanent position a ...[Read More]

NP Campfire: “Perspectives on Climate Science: from historical developments to research frontiers”

Recently, the European Geosciences Union (EGU) started to support a new type of event called ‘Campfires’ that will give the Divisions the freedom to run online interactive events in a way that suits their needs. This allows the EGU Divisions to encourage interactions in their research communities through virtual informal meetings. In this framework, and thanks to a group of young and established s ...[Read More]
