East Asian aerosol cleanup has likely contributed to the recent acceleration in global warming - Communications Earth & Environment Restrictions of atmospheric aerosol and precursor emissions in East Asia have contributed to the observed global surface warming acceleration since 2010, according to Earth System Model simulations is...

New article published today by my colleague @bjornsamset.bsky.social in Nature Comms: Earth and Environment. Evidence from eight Earth System Models that the reduction in East Asia's (primarily China's) air pollution is consistent with the sharper growth in warming.

Havets framtid på den røde løper i Nice Som i filmfestivalen vanker det både ris og ros når den store havkonferansen går av stabelen på Frankrikes sørlige kyst. Godt da at Norge stiller med et sterkt lag.

Sustainable ocean planning & management is key if we are to solve ocean sustainability challenges & the triple-planetary crisis.

Ny studie: Havets kjemper i fare Selv ikke et fullt vern av 30 prosent av verdens havområder vil være nok til å beskytte de største dyrene i havet, viser en ny internasjonal studie.

UN-Backed Study Highlights How Tracking Ocean Giants Advances Marine Conservation A groundbreaking global initiative, known as MegaMove, has brought together nearly 400 scientists from over 50 countries in an unprecedented effort to map the space use of more than 110 species of marine megafauna. This collective endeavor, harnessing decades of sophisticated animal tracking data, represents the most extensive attempt to date to identify critical habitats and migratory corridors that these iconic ocean giants depend upon.

MegaMove uncovers where protection is needed for marine megafauna A new Science paper maps global hotspots for marine megafauna & finds that planned increased protection will be insufficient to cover most areas

📢A MegaMove milestone has just been published in @ScienceMagazine!
With ~380 collaborators from 50 countries, we mapped the movements of 12k+ marine megafauna to identify key habitats 🌊🐋🦈

New mega-paper on mega-fauna movement and area use out in Science: 6.8million locations, 111 species spanning all oceans. Great job by @anammsequeira.bsky.social & team. Honored to be among the >400 authors she pulled together: www.science.org/doi/10.1126/...

The EAF Nansen programme which is developing & promoting more sustainable fisheries management, celebrates it's 50th anniversary in 2025!🥳🎉

Trump loves Norway! But I wonder what he likes the most about my country. There’s a lot to love!

The Nansen Programme Ecosystem Approach to Fisheries (EAF) Transformative Research Challenge Price for 2025 has been launched. youth.world-food-forum.org/innovation-l...

Major budget cuts proposed for the National Oceanic and Atmospheric Administration The agency forecasts weather, manages fisheries, and researches the world's oceans, atmosphere, and climate. The proposed budget cuts would slash the climate work entirely.

If the planned cuts to NOAA go through it will be devastating for climate and fisheries science, both in the US & globally www.npr.org/2025/04/11/n...

Yeah - I felt really sorry for him too

I think it was a career diplomat. He ended his intervention by thanking for the long collaboration with FAO & saying he was now leaving his post. I didn’t get if he was leaving the service or was being reposted somewhere else

Today FAO’s Council discussed «Global food security challenges & drivers».

Almost all highlighted increased hunger & the need of multilateral solutions.

🇺🇸 instead demanded that FAO should get back to its core mandate, ditch DEI , & that US support to FAO should directly benefit US taxpayers 😣

This map (by @theguardian.com ) really shows how #TrumpTarriffs hit the global south. No more US support for global development that's for sure. Better let the people Madagascar, Lesotho, Cambodia, Laos & many more suffer & continue living in poverty. www.theguardian.com/us-news/2025...

You're probably right... But in addition to ignorance another key factor is a total lack of empathy. How else can you explain dismantling USAID, revoking DEI initiatives and all the other horrible actions he has taken?

Exactly! Neo-colonialism getting in vogue again 😡

Also, it seems they got an AI to do their calculation without any QC. How else can you explain including uninhabited Islands (Heard and McDonald Islands) on the list, or ridiculous high tarriffs for island territories like Reunion and the Falklands?

In all the outrage on how #TrumpTarrifs will impact EU, & the west, effects on the Global South is worse.

Lesotho, Cambodia, Laos & Madagascar get ̈47-50% tarrifs 😡. These are among the worlds 30% least developed nations & need help to grow their economies, not destroy them.

French scientist denied US entry after phone messages critical of Trump found France’s research minister said the scientist was traveling to Houston for a conference when his phone was searched

Goodbye freedom of speech, and no travels to the US the coming 3,5 years for me.

Seems that writing private messages being critical of Trump will get you denied entry to the US 😪

Happy International Day of Women & Girls in Science🌊

We asked Marta Ferraro @marineinst.bsky.social about the importance of community -

🗣Community & mentorship play an important role in empowering #WomenInSTEM, just as human knowledge & connection are essential for our ability to thrive.

First work-week in FAO, Rome where I’m a visiting scientist until May. Looking forward to the weekend for seeing sights & savoring the atmosphere, food and drinks 😎

Today encrypted communication has suddenly become important for everyone wanting to #resist the Trump/Musk coup & the US gag-order. I'm no expert, but I've started using @signal.org for secure messaging, and ProtonMail (@proton.me) for email.

Be like Ellen and stand up against the coup 💪
