🌊 NEW STUDY: The 2023-2024 El Niño triggered the largest sea level surge EVER recorded across Africa's oceans, surpassing even the powerful 1997-1998 event. Our new paper in @CommsEarth explains why this happened and what it means. 🧵 Thread below

"Sea-level rise poses a significant threat to Africa’s vital coastal ecosystems & the livelihoods of its growing populations... The rate of rise has accelerated markedly to 4.34 mm/yr since 2010, over 4 times the 1990s rate... this uneven rise intensifies risks for over 50 million coastal residents"

Accelerating sea level rise in Africa and its large marine ecosystems since the 1990s - Communications Earth & Environment

Sea-level rise in African large marine ecosystem has accelerated markedly since 2010, mostly due to ice sheet loss and land subsidence, with the Red Sea and Guinea Current rising fastest, according to...

[4/8] L’étude montre que 80% de cette hausse provient de l’ajout d’eau lié à la fonte des glaciers et calottes polaires. L’expansion thermique de l’océan ne compte que pour 20%, un contraste net avec la moyenne mondiale où les deux mécanismes sont plus équilibrés.

Thank you for featuring our study! Africa is now more than ever at the forefront of cumulative extremes, which have been amplified by recent El Niño events. 📈

🚨 Our new paper is out! First study focusing on African sea level rise from 1993 to present 🌊🌍 Sea levels accelerated 4.5× since the 1990s, from 0.96 to 4.34 mm/yr. 2023 broke records across 40% of African waters. Thread ⬇️ 📖 doi.org/10.1038/s43247-025-02965-z
