Melissa a l’air de passer un peu à l’ouest d’Haïti, ils vont peut être éviter le pire. La Jamaïque en revanche.. Ç’est terrible dans tous les cas.

Fascinante vidéo

Let’s be clear about what happened to Jimmy Kimmel Trump’s most brazen attack on free speech yet.

After years of complaining about cancel culture, the current administration has taken it to a new and dangerous level by routinely threatening regulatory action against media companies unless they muzzle or fire reporters and commentators it doesn’t like.

🌡️La France a connu du 8 au 18 août 2025 sa 51e vague de chaleur depuis 1947.

Son intensité maximale est comparable à celle des épisodes d’août 2023, juillet 2022 ou juillet-août 2018.

Sur le Sud-Ouest les niveaux de chaleur ont parfois dépassé ceux de la canicule de 2003.

🇺🇸 Sans la photo cela aurait été presque impossible d’y croire.

Hier, après avoir téléphoné à Poutine, Trump a invité Zelensky et les leaders européens dans sa petite « boutique » à souvenirs pour leurs offrir du merch MAGA.

Dont la casquette pour qu’il reste 4 ans de plus au pouvoir.

#Wildfires in Spain have reached record emissions in just one week according to our #CopernicusAtmosphere data.

Every Democratic member of Congress should be in the streets of DC saying this dangerous authoritarian escalation must stop. Do they not grasp what’s going on here?

Short opinion in Nature with my friend Bernard Pinty. Historical climate data records are so essential for monitoring the climate.

Good luck @ec.europa.eu, @esa.int and @eumetsat.int with the launch of MetOp-SG and Sentinel 5 tonight. This is European leadership!

Speechless..

Excellent fil!

@cnrsecologie.bsky.social regrette profondément l'adoption de cette loi à la vision court-termiste & ses conséquences graves sur l’environnement, qui méprise santé & bien-être de la population & le rôle des espèces sauvages dans la prod. agricole. La communauté scientifique n'a pas été entendue.

Graphic showing a vertical cross-section of zonal mean temperature trends globally for June from 1979 through 2024. There is a long-term warming trend in the troposphere and cooling in the stratosphere. Red shading is shown for warming trends, and blue shading is shown for cooling trends.

Here is a vertical cross-section view of how temperatures are changing in the atmosphere during the month of June. The x-axis shows each latitude band. The y-axis is representing height in the atmosphere, starting from the near-surface at the bottom & reaching up toward the stratosphere. Data: ERA5.

Limiter le réchauffement climatique à 1,5 °C est désormais impossible Selon un collectif de scientifiques, l’objectif fixé par l’accord de Paris en 2015 ne pourra pas être atteint en raison de l’incapacité des pays à diminuer les émissions de gaz à effet de serre.

Our ECMWF colleague Dr @annalombardi.bsky.social speaks to the power of data visualisation in telling the story of our evolving climate. From her cover art based on decades of temperature data to 130+ charts, read how data was converted into easy-to-understand graphics in the #ESOTC2024.

Effective May 5, 2025, NOAA’s National Centers for Environmental Information (NCEI) will decommission its snow and ice data products from the Coasts, Oceans, and Geophysics Science Division (COGS). As a result, the level of services for affected products below will be reduced to Basic—meaning they will remain accessible but may not be actively maintained, updated, or fully supported. This includes Sea Ice Index, Snow Data Assimilation System (SNODAS) Data Products, Glacier Photograph Collection, U.S. National Ice Center Arctic Sea Ice Charts and Climatologies in Gridded Format Gridded Monthly Sea Ice Extent and Concentration, 1850 Onward World Glacier Inventory. If you rely on these products in your work, research, education, or planning, we invite you to share your story at nsidc@nsidc.org. Your input can help us demonstrate the importance of these data sets and advocate for future support.

This is horrible. I don't even know what to say. Some of our most key polar data.

More than art, a data story.

Is Trump Going to Screw Up America's Weather Forecasting? Trump and DOGE’s cuts are disrupting NOAA and the National Weather Service. It could impact your ability to get reliable weather forecasts.

and what about international collaboration, which has so far been instrumental in bringing numerical weather prediction where it is today, if DT decides we scientists can’t talk to each other any longer?

🌡The March 2025 Climate Bulletin is out. It was the warmest March on record for Europe and the second-warmest March globally, with a global average surface air temperature of 14.06°C, 1.60°C above the pre-industrial level for March.
