New paper from our group in the Journal of Open Source Software: the Julia package WhereTheWaterFlows.jl by Mauro Werder and Christophe Ogier computes where water flows on elevation models and underneath glaciers, including uncertainty estimates.

Last Friday evening (16 October), I suspended the 65th Plenary Session of the IPCC in Addis Ababa. The work of this Plenary hasn’t finished. We will reconvene the plenary at the earliest opportunity.

Arctic winter sea ice is likely to shrink by about 1 million square kilometers more than previously projected, based on clues from a warmer Arctic 6,000 years ago. @Cambridge_Uni @NatureGeosci phys.org/news/2026-10-winter…

Swiss glaciers lost 5% of their ice in 2026, accdg to GLAMOS. Their total volume has shrunk by nearly 20% in the last 5 years.
This echoes the WMO’s #StateOfWater 2025 report, which found that every glaciated region on Earth lost ice in the last 5 years.

Since 2025, ICIMOD has established the Hindu Kush-Himalayan Futures Forum (H2F2), an informal but influential think-tank of eminent diplomats, academics, and experts drawn from ICIMOD’s member countries to provide high-level strategic advice and thought leadership.
The 2026 edition, its second chapter, has begun today in Pokhara, Nepal (15 to 18 October 2026), exploring pathways to strengthen regional cooperation and advance regional leadership.
In just the past few weeks, Nepal has witnessed devastating mountain disasters. The catastrophic Bhote Koshi flood in Rasuwa and the recent Budhi Gandaki flood in Gorkha have demonstrated how cascading hazards involving glaciers, rockfalls, landslides, water, and sediment are becoming increasingly destructive in our mountains.

The Congo Basin is one of the few regions where the IPCC has failed to track long-term changes in extreme heat.
The problem is a lack of data. To fill this gap, scientists digitized thousands of handwritten records, which reveal the impact of warming.

#Isaias has strengthened into a major Category 3 hurricane. Infrared imagery from @NOAA’s #GOESEast (#GOES19) 🛰️ is tracking Isaias as it approaches the northern Gulf Coast, where dangerous conditions are expected—including hurricane-force winds, life-threatening storm surge, flash flooding and possible tornadoes.

BREAKING: Isaias is now a Category 3 hurricane, the first of the 2026 Atlantic hurricane season and the first in the Atlantic Basin since Hurricane Melissa last October. READ MORE: weather.com/2026/10/09/storm…

BREAKING: Hurricane Isaias is now a Category 2 storm and is expected to make landfall along the Gulf Coast Friday night, bringing life-threatening storm surge, damaging winds and flooding rainfall. READ MORE: weather.com/2026/10/08/storm…

Eye of Hurricane Isaias now forming -- rapidly. Dangerous next 24 hours ahead as the hurricane sits over the deep and warm "Loop Currrent" and the same area that powered history's most intense storms.
We can only hope for wind shear to retard the intensification.

#Isaias is now a #hurricane - the first of the 2026 Atlantic season. The last season with zero Atlantic hurricanes was 1914. Of course, our observational system is much better now than it was in 1914, so we may have missed hurricane(s) that year.

#HurricaneWarnings and #TropicalStormWarnings are in place along the Gulf Coast from Louisiana to Florida today as #HurricaneIsaias swirls offshore. @NOAA’s #GOESEast (#GOES19) 🛰️ captured this imagery of the cyclone, which is expected to make landfall in the coming days.

🌀Have you noticed the National Hurricane Center is testing a new track cone this season?
The new experimental graphic draws the cone using ovals (instead of circles) that separate forward speed from left-or-right track errors and cover 90% of possible track outcomes (up from the traditional 67%). Look for "EXPERIMENTAL" in red at the bottom left of the map.
What do you think of the new design? Share your feedback: surveymonkey.com/r/ProposedC…

El Niño continues to strengthen, with a strong-to-very strong El Niño likely through January-March 2027 (remaining greater than an 83% chance). An #ElNino Advisory remains in effect. #ENSO cpc.ncep.noaa.gov/products/a…

The color shading within the bars indicates the chances of different categories of El Niño or La Niña strength (weak, moderate, strong, and very strong).
