The temperatures of the Mediterranean Sea in recent days have reached heat records set last summer, the main Spanish maritime research center told AFP Tuesday, with marine heat waves in some places exceeding 30 degrees Celsius.
Greece, Italy, Spain, Portugal, France and Morocco experienced extreme heat in July 2024, causing at least 23 fatalities, widespread wildfires and bringing public life to a hold.

Climate scientists have expressed shock at the UK’s smashed temperature record, with the heat soaring above 40C for the first time ever on Tuesday. Researchers are also increasingly concerned that extreme heatwaves in Europe are occurring more rapidly than models had suggested, indicating that the climate crisis on the European continent may be even worse than feared. Temperature records are usually broken by fractions of a degree, but the 40.2C recorded at Heathrow is 1.5C higher than the previous record of 38.7C recorded in 2019 in Cambridge.
It doesn’t even work yet, but nuclear fusion has encountered a shortage of tritium, the key fuel source for the most prominent experimental reactors.
UV filters absorbed by Posidonia oceanica may have damaging effects on ecosystems, scientists warn
How close is nuclear fusion to break-even? If you trust the headlines we're getting close and the international project ITER is going to be the first to produce energy from fusion power. But not so fast. Scientists have, accidentally or deliberately, come to use a very misleading quantity to measure their progress. Unfortunately we're much farther away from generating fusion power than the headlines suggest. "Donc, si tout va bien, l'EROEI d'ITER sera de 0,4 ou 0,5 pour 1 - encore plus minable qu'un biocarburant basé sur les algues. " - Philippe Gauthier
