0 mm... Driest July on record at Kew (SW London) since 1800! 💧🔥 1800 also recorded no measurable rainfall, but July 2026 was the hottest month on record, which results in a combination very impressive for the area! 😲 Please note that the local records go back to 1697! ⏱️ 📈 Via @metjam.co.uk

Ferpècle Glacier (Val d'Hérens, Valais) 2016 | 2026 The worst decade ever! 🧊🔥 Valley glaciers have virtually disappeared from the Alps (except the five largest)! 😰 To think that this glacier was connected to Mont Miné Gl. until 1956! ⏱️ 📷 2026 pic (taken today) by Sandra Belin-Gorsic 🙏

Tree rings are the best proxies for Holocene climate reconstruction! 🌲💍 This work shows that Northern Hemisphere Common Era natural variability was ca 4°C, extended to 5.5 °C during the 21st century! 🔥 What are considered "warm periods" (RWP, MCA) aren't really that hot compared to the 21st c.! 📈

Today's aerial view of the Tour Ronde rock avalanche deposit that occurred last sunday! 😲 An allegory of a north face of a 3,800 m peak in the 21st century... not a single ounce of ice left! 🔥🧊 📷 Gilles Léger 🙏

Glacier Noir (Écrins Massif) 18th Aug. 1953 | 19th July 2026 Debris-covered glaciers are no exception! 🧊🔥 The hanging glacier of the Coolidge east face no longer exists btw ✝️ 📷 1953: Eaux et Forêts

I've never seen anything like it. Salta, Argentina, has just recorded its hottest night on record during the climatologically coldest time of the year. The minimum overnight temperature did not fall below 26°C (78.8°F), pulverizing the previous monthly record by 7°C.

A rock avalanche of impressive magnitude took place yesterday (July 19) on the north face of Tour Ronde (3,793 m asl) ! 🔥 A summit where this kind of events became recurrent in recent years with warming permafrost... 📽️ Maxim Foygel

Barre des Ecrins (4,102 m asl) from top of Pic du Glacier Blanc (3,527 m asl) yesterday ! 😍 Aside from the feeling of facing a gorgeous glacial landscape, snow conditions are apocalyptic for July, with a snowline already ~3,100 m! 🧊🔥 Likely on track to set a new ice ablation record this year! 📈

Glacier du Casset (NE Face Les Agneaux, 3,664 m asl) Juillet 2007 | Juillet 2026 At this pace in the Alps, all mountain glaciers (≠ valley glaciers) located entirely below 3,500 m will be gone within next two decades at most! 🧊🔥

Love this view of the Avérole Valley showcasing the perfect pyramid of the ice-capped Pointe de Charbonnel (3,752 m asl), the highest peak in the Graian Alps! 🏔️🧊 Background left is Baounet Glacier, one of the largest of the Upper Maurienne Valley 📷 Paul Helbronner (first decade of the 20th c.) ⏳

The Mont Pourri (3,779 m) and Dôme de la Sache (3,591 m) glacier complex a few days ago! 🏔️🧊 Mind-blowing withdrawal of what was once one of the most beautiful glacial systems in the Vanoise (Gurraz/Savinaz Gl.)! 🔥

After three heatwaves since May, we are living in France the worst drought in history! 🔥💧 Soil moisture has reached level unprecedented this early in the summer — exceeding the levels recorded in 1976, 2022, and 2025 on the same date! 📈 Via @MystereMeteo
