The same message, in French and Arabic, to announce that France was going to “mobilize resources to provide emergency aid”. Emmanuel Macron presented his “condolences” on Monday evening to the Libyan people, who are suffering the full brunt of the consequences of Storm Daniel. The latest official report this Tuesday morning shows more than 2,000 deaths, a number described as “enormous” by the Red Cross which also mentions up to 10,000 potential missing people.
My solidarity with the Libyan people who are suffering terrible floods. France presents its condolences to the families of the victims and is mobilizing resources to provide emergency aid.

A few days earlier, Daniel had struck Greece where villages were ravaged by water and 14 people were killed, according to a final report. Be careful not to confuse it with tropical storm Danielle, which formed at the end of August in the middle of the Atlantic Ocean. As always, the question arises as to whether this European storm is linked to climate change?
Attribution study
To answer it precisely, we will have to wait for the results of an attribution study. This science is increasingly “fashionable” and practiced by more and more researchers, who seek to establish to what precise extent climate change has made a particular climatic phenomenon more likely. But by then, we already know that Daniel was formed at the end of an “Omega” blockage, named after the Greek letter. In the center: an anticyclone with very high temperatures. At both ends: rain and cool temperatures.
However, the effects caused by this type of situation are “boosted” by climate change. “With equal atmospheric circulation, this omega would not have had the same impacts in the 1950s or 1960s,” climatologist Christophe Cassou, CNRS research director at Cerfacs in Toulouse, explained to us last week.
Analysis on-line this Tuesday confirms it: if the formation of this atmospheric blockage is linked to natural climate variability, the temperatures observed in France and the United Kingdom were between 2ºC and 4ºC higher than in the past, due to the change climatic “That’s a lot, because normally we have around 1.5°C of warming in France,” says Davide Faranda, lead author.

More generally, the Mediterranean basin is a “hop spot” for climate change, that is to say an area of the globe which is experiencing its effects more than others. This region is warming faster than the global average.
“In the Mediterranean, climate change will be one of the most radical in the world. This fact is established with a high level of certainty. All types of phenomena are changing there: heat waves, cold waves, floods, extreme rain, droughts, fire risks, drop in average winds, increase in Mediterranean cyclones, coastal phenomena…” told the site in August 2021 touteleurope.eu climatologist Robert Vautard, now co-chair of IPCC working group 1.
