Preliminary results of a large study with contributions from 80 heart-breaking scientists. The Mediterranean, cradle of our cultures, landscape of the founding myths of our civilizations, crossroads of three continents, living basin of 500 million human beings, the Mediterranean of Giono, Pagnol, like that of Averroes or of

Après l’épisode caniculaire qui a frappé ces dernières semaines l’Europe en général et la France en particulier, doit-on s’attendre à un retour des grandes sécheresses ? Les météorologues nous prédisent une saison estivale des plus chaudes ; les hydrogéologues, qui mesurent l’état des nappes phréatiques et des réserves d’eau françaises, sont

The planet is overheating and some, like climatologist Jean Jouzel, predict that we will soon be "toasting slowly". Controlling greenhouse gas emissions has become a mantra, but even if we succeed, it will probably be too late. We must

Precious resource, the water will run out. And, faced with the risk of drought forecast for this year 2019, after the rather severe drought of 2018, the Ministry of Ecological and Solidarity Transition wants to put in place a number of preventive and indispensable measures in France, as concern is being felt. Indeed, the

Since the beginning of December, the UN has been conducting an intense awareness campaign to warn about pollution and land degradation (#StopSoilPollution). It draws up a worrying report that could put a large part of humanity at risk. Indeed, degraded soils become irrecoverable in less than a generation. Pollution

As if suffering from heat, droughts, floods and storms were not enough, a new UN report states that climate change is also increasing hunger in the world: in 2017, for the third year, the number of people in chronic hunger

The links between global warming and geopolitical risks and migration are no longer to be demonstrated. The UN Security Council has just published an alarming study: if nothing is done quickly to mitigate the extreme climate risks in Iraq, the jihadist group Islamic State (IS) may find itself back in a "climate crisis".

The king of the African savannah, the tree of life, the pharmacist tree, the magic tree, the millennium baobab tree, is disappearing. Silently and mysteriously. An international team of researchers is making this tragic observation: the oldest baobabs in Africa are dying. We do not know the causes of

South Africa, and particularly Cape Town, is suffering from an unprecedented drought. The municipality has even announced that the taps could be closed during August. To solve this serious crisis, a sea rescue specialist has come up with a crazy idea: towing an iceberg from Antarctica and

Parmi les ressources naturelles il en est une des plus fondamentales car elle est la source de la vie, c’est l’eau. Notre planète regorge d’eau douce mais pourtant elle subit une crise qui ne fait que s’aggraver avec le changement climatique. L’eau est inégalement répartie, mal utilisée, souvent gaspillée. De

Ice melting is accelerating in Greenland. The massive introduction of freshwater into the Atlantic could cause very severe droughts in the Sahel and a major migration crisis. Two areas that are at odds with each other but are nevertheless linked by global warming: Greenland, an uninhabited icy land, and the Sahel, a tropical zone.

Nous vous avons relaté récemment les prévisions alarmistes des climatologues qui estiment que la chaleur et la sécheresse rendront invivables des régions entières du Moyen-Orient et d’Afrique du Nord. Pour éviter ce cataclysme, certains ne manquent pas d’idées. C’est le cas des Émirats Arabes Unis qui envisagent de construire une
PlusDes scientifiques de l’Académie américaine des sciences ont déterminé que l’augmentation du CO2 (dioxyde de carbone) dans l’atmosphère, responsable du réchauffement, réduit les besoins en eau des végétaux qui deviennent moins sensibles à la sécheresse, un facteur qui n’est pas pris en compte dans de nombreux modèles hydrologiques. Cette

Pour notre planète, quelle serait la différence entre une hausse de 1 degré et demi et une hausse de 2 degrés ? On l’ignore, parce que les scientifiques ont à peine commencé à mener des recherches spécifiques de la cible de 1 degré et demi. Il y a une
