LISTE DES PLANS
- Plan extérieur moyen : allée des drapeaux de l'ONU.
- Plan large du podium dans la salle de conférence de presse.
- EXTRAIT SONORE (Anglais) Lorenzo Labrador, Responsable scientifique, OMM : “Presque tout le monde sur Terre, en gros neuf personnes sur dix, respire un air qui est essentiellement impropre à l'usage. Cela signifie que cet air dépasse les limites des directives de l'OMS et contient un niveau élevé de polluants, les pays à revenu faible et intermédiaire étant les plus touchés.”
- Plan moyen-large, orateurs au podium et salle de presse.
- EXTRAIT SONORE (Anglais) Lorenzo Labrador, Responsable scientifique, OMM : “La pollution de l'air ambiant seule, provenant principalement des véhicules et de l'industrie, cause plus de 4,5 millions de décès prématurés par an. Pour donner un contexte, c'est plus que les décès dus au paludisme et au VIH/SIDA combinés ; donc la pollution de l'air est le plus grand risque environnemental de notre époque. Mais ce n'est pas seulement un risque pour la santé en soi, cela exacerbe également le changement climatique.”

- EXTRAIT SONORE (Anglais) Lorenzo Labrador, Responsable scientifique, OMM : “Nous avons tendance à croire que la baisse de la pollution en Europe et en Chine est le résultat direct d'une réduction des émissions dans ces pays au fil des ans, et nous avons remarqué cette tendance depuis que nous avons commencé à publier le bulletin en 2021. Donc, nous pouvons dire que nous commençons à voir une tendance à cet égard.”

- EXTRAIT SONORE (Anglais) Lorenzo Labrador, Responsable scientifique, OMM : “Alors que les particules fines sont responsables d'environ huit millions de décès prématurés par an dans le monde, il n'est pas surprenant que l'accent soit généralement mis sur les effets des particules fines sur la santé. Cependant, un rapport de l'Organisation météorologique mondiale de 2023 a souligné que les particules fines peuvent gravement affecter la productivité des cultures - des cultures de base - telles que le maïs, le riz et le blé.

- EXTRAIT SONORE (Anglais) Lorenzo Labrador, Responsable scientifique, OMM : “Une grande partie de cette pollution par les particules fines qui affecte les rendements des cultures est due à des pratiques humaines, notamment les pratiques d'utilisation des terres telles que le labour et la récolte. De plus, l'application d'engrais et le brûlage des chaumes à la fin de la saison, des saisons de croissance.”
- Plan moyen, mains de l'orateur sur le bureau et écran.
- EXTRAIT SONORE (Anglais) Lorenzo Labrador, Responsable scientifique, OMM : “Nous avons rapporté en 2022 la saison des incendies de forêt de 2021 en Sibérie, qui était très, très forte. Mais il y a des indications que l'incendie de forêt que nous avons eu au Canada l'année dernière était encore plus fort en termes d'émissions. Il a battu des records concernant la superficie brûlée sur une période de 20 ans au Canada.”
- Plan moyen-large, vue surélevée des orateurs au podium et salle de presse.
- EXTRAIT SONORE (Anglais) Lorenzo Labrador, Responsable scientifique, OMM : “La première chose que les villes doivent faire est de reconnaître que le problème existe en premier lieu. Donc, ces villes et ces pays doivent d'abord reconnaître qu'il y a un problème de qualité de l'air et il y a suffisamment de données dans le monde pour reconnaître essentiellement que c'est un problème mondial, en particulier dans les zones urbaines.”

As world’s water reserves change, countries must prepare for a new reality: WMO
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:
- 2025 was one of driest years for river discharge in 35 years
- Past seven years have seen abnorfmal river flows
- Water storage on Earth’s land surface has decreased in past decade
- Widespread glacier loss across all regions for fourth consecutive year
- Asia and Africa are regions most affected by water-related disasters
- Water data availability has improved, but gaps remain in hard-hit areas
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”.
