The 2022 European summer was governed by the presence of a persistent cold drop (low pressure area) located between Portugal and France. The change in its position has determined the alternation between hot conditions (low pressure center over Portugal) and stormy conditions (cold drop over France). The warming of the Mediterranean Sea (up to +6°C compared to the period 1990-2020) has largely cont ...[Read More]

NP Interviews: Davide Faranda (CNRS) on the topic “global warming and extreme events in Europe”

Davide Faranda is a physicist at the French National Center for Scientific Research (CNRS). His main interests are devoted to the construction of a statistical mechanical and dynamical systems framework for the study of atmospheric motions. In particular, his works aim at the characterization of the metastable states of the atmospheric circulation with simple mathematical and statistical tools, an ...[Read More]

A few reasons making the June 2022 French Heatwave too hot & too soon
Picture (by Chris Walts): original way to stay cool during hot days in Paris.

Too hot, Too soon: the thermometer has reached unprecedented temperature for a month of June in France, with the 40°C mark crossed by Friday June 17 in part of France. The IPCC AR6 report now clearly states that the probability of heatwave events such as this one has increased by a factor 3 to 5 in the present climate with respect to a counterfactual world not affected by anthropogenic greenhouse ...[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]
