L'ONU renforce son soutien aux plus vulnérables dans la "plus grande catastrophe climatique" du sud du Brésil
Les inondations soudaines au Brésil tuent au moins 163 personnes et déplacent 600 000 personnes
Des inondations et des glissements de terrain sans précédent ont touché plus de deux millions de personnes dans l'État brésilien de Rio Grande do Sul, où presque toutes les villes ont été touchées. Un stupéfiant "93 pour cent des villes et villages" ont été touchés, selon l'agence des Nations Unies pour les réfugiés, le HCR.
S'exprimant devant les journalistes à Genève, l'orateur William Spindler a expliqué que les inondations sont devenues la plus grande catastrophe climatique dans le sud du Brésil. Plus de 65 000 personnes déplacées par l'urgence sont encore abritées dans des centres improvisés.
L'inondation de ce mois est la quatrième que le Rio Grande do Sul a subie en un an, après les inondations de juillet, septembre et novembre 2023 qui ont tué 75 personnes.
En collaboration avec les autorités nationales, le HCR étend sa réponse pour soutenir les plus vulnérables, y compris 43 000 réfugiés et autres personnes ayant besoin de protection internationale, principalement des Vénézuéliens, des Haïtiens et des Cubains.
"Une estimation de 3,21 millions de dollars est nécessaire pour soutenir la réponse du HCR, y compris une assistance financière aux personnes touchées et des articles de secours essentiels", a déclaré M. Spindler, qui a noté que le changement climatique affecte de manière disproportionnée les réfugiés qui vivent déjà dans des conditions précaires.
Dans le cadre de la réponse, une équipe du HCR spécialisée dans la gestion des abris, la documentation et la prévention de la violence basée sur le genre a été mobilisée dans les zones sinistrées et coordonne la réception des articles de secours.
Dans un développement connexe vendredi, l'Organisation météorologique mondiale (OMM) des Nations Unies a mis en avant une alerte au cyclone tropical de l'Institut national de météorologie du Brésil. "Un cyclone extra-tropical se développe dans l'océan à la hauteur de la côte du Rio Grande do Sul et apportera plus de pluies avec des vents constants. Cela va évidemment aggraver la situation", a averti la porte-parole de l'OMM Clare Nullis.
Depuis 2000, les catastrophes liées aux inondations dans le monde ont augmenté de 134 pour cent par rapport aux deux décennies précédentes, selon le rapport de l'OMM de 2021. L'intensification du changement climatique a considérablement contribué à l'augmentation de la fréquence et de la gravité des événements météorologiques extrêmes, tels que les inondations dévastatrices dans le sud du Brésil, mais aussi les catastrophes en cours en Afrique de l'Est et en Afghanistan où plus de 300 personnes sont mortes dans des inondations soudaines la semaine dernière.
Bien que les pays aient investi dans des projets d'infrastructure pour prévenir les dommages causés par les inondations, les agences des Nations Unies, y compris l'OMM, ont souligné la nécessité d'une réponse plus intégrée aux impacts d'El Niño et du changement climatique, en particulier en investissant dans la technologie d'alerte précoce.
"Il est vraiment rentable d'investir dans les services météorologiques et hydrologiques nationaux. Pour chaque dollar investi, vous obtenez des retours beaucoup, beaucoup plus importants. Et ce même principe s'applique aux services d'alerte précoce", a souligné Mme Nullis.

New data showing that rivers were at their lowest level for decades last year provides further evidence that the climate crisis is real and countries must act immediately to protect themselves from the increasing threat to communities and livelihoods, the UN World Meteorological Organization (WMO) said on Thursday.
The key findings from WMO’s State of Global Water Resources 2025 report covering the hydrological cycle and extreme events in the five-year period to last year:
Highlighting the long-term decline in the Earth’s freshwater storage and glacier melt, WMO Secretary-General Celeste Saulo explained that the planet’s water reserves used to act as a planetary “savings account” that absorbed the occasional dry season, avoiding a water crisis. “One of the central stories of the 2025 report is what is happening to that savings account? And the simple answer is that we are depleting it,” she told journalists in Geneva.
Groundwater reserves are equally stretched and have been in decline since 2014, WMO’s report states, with nearly two-thirds of monitored wells worldwide showing levels lower than the historical norm and indicating a shift “further toward deficit…not recovery”.
“At the same time, we are seeing more water-related disasters,” Ms. Saulo said, while also stressing that the currently strengthening El Niño “will increase the risk of drought in some areas, and flooding in others”.
Glaciers disappearing
In 2025, for the fourth consecutive year, every major glaciated region on Earth lost ice mass, leading to short-term hazards including floods and long-term water insecurity, according to WMO.
Responding to a question about whether the changing global water cycle might have contributed to the deadly Nepal-China flooding disaster, Ms. Saulo explained that melting ice and rock was just one factor in the chain of events that ultimately sent a massive and deadly wall of water and debris downstream on 26 August, killing at least 1,367 people.
“You asked if it could happen again? Absolutely; the problem in this region is that there’s 63,700 glaciers at the last count,” she told a Press Conference in Geneva. “Even if you’re looking with remote sensing with satellites at these glaciers, you might see some faults, you might see some slight shifting, that does not mean necessarily catastrophic collapse. So, in order to plan for this, it’s very, very difficult. But the international community is looking very hard at ways in which we can bring people together to solve some of these monitoring issues.”
Data indicates that glaciers shrank between 2023 and 2025 with cumulative losses of 1,400 gigatonnes of water – or about one third of annual fresh water needs.
Every major glacier region on Earth lost ice for the fourth consecutive year.
“All 19 glacier regions around the globe lost ice; in Central Asia, Iceland, the Russian Arctic and western Canada and the United States, it was among the three worst years on record,” said Wayne Jenkinson, WMO’s Director of Hydrology and Cryosphere.
Some regions with smaller glaciers such as Central Europe, the Caucasus, the western Canada and the United States may already have reached “peak water”, Mr. Jenkinson warned.
“After this point, the glacier gives less meltwater each year simply because there is less ice left to melt. That matters for every community downstream that relies on water during hot, dry summers,” he explained.
Narelle van der Wel, WMO’s Head of Cryosphere Monitoring, Predictions and Services, stressed that while some further glacier loss is unavoidable, the eventual scale of the decline is not predetermined.
“Some glacier loss is inevitable, but total loss of glaciers is not yet inevitable,” she said, pointing to emissions reductions as central to limiting future losses.
Preparing for moving baselines
The report does not attribute every observed change to climate change alone. WMO says pressure on water resources and natural variability also contribute.
Mr. Jenkinson said governments need to prepare for “moving baselines” as historical patterns become less reliable.
“The situation 30 years ago is not where we are today,” he said. Countries, he added, need to prepare “for those changes that have really already arrived”.
