El Niño typically has a warming effect on global temperatures, with the strongest influence often felt in the year after it develops. It typically brings wetter conditions to some regions and drought to others, though effects vary around the world. More 👉 bit.ly/4uqZexj

As El Niño is forecast to intensify, the risk of heatwaves, droughts, heavy rainfall & other extreme weather is increasing. The WMO community steps up coordination, climate info services & #EarlyWarnings to help countries prepare for potential impacts. ➡️ bit.ly/4y6E9LE

"Western Europe had its hottest June on record," Clare Nullis from the World Meteorological Organization told reporters. The @WMO and @WHO are working together to mobilize heat-health action plans to help protect lives under these extreme conditions. news.un.org/en/story/2026/…

The most significant areas with severe and extreme heatwaves in 2025 were near the coasts of Australia, and in the western South Pacific between New Zealand, New Caledonia and Vanuatu. 🔖 Read the WMO #StateOfClimate in the South-West Pacific 2025 report: bit.ly/SOTC-SWPacific…

It's not just the daytime highs that matter for our health. High overnight temperatures make hot days more hazardous and increase overall heat stress. Understand the difference between hot days, heatwaves, and their effects to your health: bit.ly/3R5yFjr

Last June saw much of western Europe experiencing a record-breaking heatwave and marine heatwaves across western Mediterranean and Atlantic coasts. Global monthly mean sea-surface temperature, excluding the polar regions, exceeded the June 2024 record. bit.ly/3R3i4go

📰 WMO Airborne Dust Bulletin Record-breaking sand & dust storms affected parts of the world in 2025, though overall average dust concentrations were similar to 2024. Accurate dust aerosol forecasting remains a challenge, but AI offers potential. #SDSday 🔗bit.ly/4w4zZT1

Every year, billions of tonnes of dust travel across continents and oceans. Ahead of #SDSday, the latest WMO Bulletin explores how sand and dust storms affect air quality, health & transport. It also explores how forecasting & early warnings help. Read 👉 bit.ly/4aWKxem

June 2026 is Western Europe’s warmest June on record and the 2nd-warmest June globally, according to @CopernicusEU Climate Change Service's latest bulletin. The global average surface air temperature was 16.54°C—1.39°C above pre-industrial levels. 🔗 bit.ly/4f7Wj7a

Humanity’s needs are rising — can AI pick up the slack? At this year's #AIforGood Summit, our Global Stage discussion examines how AI can help humanitarian institutions on the frontlines of crises and shortfalls. Our panel comprises @UN_PGA, @gioasempre, @HeadUNDRR, Prof. Celeste Saulo of the @WMO, and @Microsoft's @BradSmi with @TonyMaciulis moderating. Catch the live premiere on Thursday, July 9th at 11am ET at gzeromedia.com/globalstage.

Bavi—a large & powerful typhoon—hit the US Pacific islands on Monday, bringing destructive winds & torrential rain. It's now moving through the western Pacific & is forecast to make landfall along mainland China's eastern coast by Sunday, 12 July. 🛰️ Himawari-9 @CIRA_CSU @NOAA

🆕 report: Leveraging AI to Enhance Multi-Hazard Early Warning Systems shows how AI can strengthen disaster risk knowledge, forecasting, warning dissemination & anticipatory action—helping close critical gaps in #EarlyWarningsForAll. #AIforGood Read 👉 itu.int/go/EW4All-AI-R…

Ocean waters in the South-West Pacific are becoming hotter and more acidic, harming economies & marine ecosystems. Sea level rise is threatening coastal communities & low-lying island nations. Read the WMO #StateOfClimate in the South-West Pacific 2025. 🆕 bit.ly/SWPacificSOTC2…

WMO Global Seasonal Climate Update indicates a rapidly developing strong El Niño in July–September 2026. Forecasts indicate a significant warming of ocean temperatures across central & eastern equatorial Pacific. 🔗 bit.ly/4y6E9LE

🌦️ What does the World Meteorological Organization actually do? Our latest #GenevaKitchen with @WMO breaks down how its work on weather, climate and early warning systems helps protect lives and livelihoods around the world. 💫

El Niño conditions have developed in the tropical Pacific and are forecast to strengthen rapidly over the coming months, increasing the likelihood of heatwaves, heavy rain & extreme weather in many parts of the world. WMO briefed the media at @UNGeneva. 🔗bit.ly/4aW5kPt

The snow accumulated by Switzerland's glaciers over the winter has completely melted away, according to @glamos_ch. Without snow's protective cover, glacier ice melts faster. Heatwaves and changing climate conditions brought this year's glacier loss day much earlier than usual.

4th of July will be a hot one over central & eastern USA. Accdg to @NOAA @NWS, temperatures up to 115°F (46°C) are expected, as the country celebrates Independence Day & thousands attend @FIFAWorldCup matches. Thunderstorms possible in some areas. weather.gov

Launching 7 July: WMO #StateOfClimate in the South West Pacific report Experts will present the latest findings on climate indicators, extreme events and their impacts in the region during the Southeast Asia Marine Heatwaves Services Workshop. Register 👉bit.ly/SOTC-SWPacific…

Global ocean temperatures hit a record high for June, according to the latest Copernicus Climate Change Service & @CMEMS_EU data. Over the past three years, oceans outside the polar regions have been 0.35–0.73°C warmer than average. El Niño pushed June to a new record.

In 2014, WMO asked weather presenters to imagine a report from the year 2050. A mere 12 years later, these possible scenarios grounded in climate science are already a reality in some parts of the world as we're seeing in Europe. Watch the series ▶️ bit.ly/4eQUVW3
