The Great Cold Debate: Is Climate Change to Blame for Extreme Cold Spells?

The Great Cold Debate: Is Climate Change to Blame for Extreme Cold Spells?

In  December 2022, the United States experienced a severe cold spell, with record-low temperatures being recorded in many parts of the country. While it is natural for cold spells to occur, the question has arisen as to whether climate change is playing a role in the intensity and frequency of these events. There is ongoing debate among scientists about the relationship between climate change and ...[Read More]

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

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]

NPG Paper of the Month: “Inferring the instability of a dynamical system from the skill of data assimilation exercises”

NPG Paper of the Month: “Inferring the instability of a dynamical system from the skill of data assimilation exercises”

The NPG paper of the month was awarded to “Inferring the instability of a dynamical system from the skill of data assimilation exercises” by Yumeng Chen, Alberto Carrassi, and Valerio Lucarini. Geophysical systems are usually described by a set of dynamical equations that are often non-linear and chaotic (Ghil and Lucarini, 2020). Errors about the initial state can grow, shrink, or sta ...[Read More]

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

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]
