I’m researcher in physics at the French National Center for Scientific Research (CNRS). I’m an expert of weather extreme events such as cold spells, heatwaves, cyclones and severe thunderstorms. My research activity focuses on the attribution of extreme events to climate change, that is understanding how much greenhouse gases influence the occurrence of extremes

How Climate Sciences can help in understanding uncertainties in Covid-19 epidemic projections
Artistic view of the Covid-19 virus moving along an increasing trend.

COVID-19 is currently affecting over 180 countries in the world and poses serious threats to public health as well as economic and social stability of many countries. Modeling and extrapolating in near real-time the evolution of COVID-19 epidemics is a scientific challenge, which requires a deep understanding of the factors undermining the dynamics of the epidemics. Despite the importance of havin ...[Read More]

The 2020 extra-tropical monster cyclones and their (possible) relations with climate change

On February 9th, a British Airways Boeing 747 landed in London Heathrow airport just four hours and 56 minutes after its take-off in JFK, New York, setting the shortest flight-time for non-supersonic jets over this route. The jumbo jet took advantage of the fast upper-tropospheric winds associated with an exceptionally strong jet-stream which created tail winds of about 400km/h. Over the United Ki ...[Read More]

Australian wildfires have burned an impressively large surface and caused the death of at least 24 citizens as well as of numerous animals. This immense disaster raises questions about its linkage with climate change, the possibility of controlling these events and the future of Australian wildlife ecosystems. While the first question will be addressed by soon to come attribution studies, and the ...[Read More]

Medicanes, thunderstorms and Acqua Alta in Venice: what is the role of climate change?

Medicanes, thunderstorms and Acqua Alta in Venice: what is the role of climate change?
The image shows a schematic representation of the extreme events associated to the medicane Detlef/Bernardo. The basic images is the infrared image from the EUMETSAT satellite network.

A Mediterranean cyclone, high tides and climate change: these three ingredients made the 12/11/2019 acqua alta event in Venice exceptional. This combination of causes determined what climate scientists define as a compound extreme event, a non-linear mix of factors which led to several and connected extreme weather phenomena in the Mediterranean area. Let us start by the analysis of the atmospheri ...[Read More]
