More than 450,000 additional heat deaths could occur globally by February as a super El Niño drives extreme temperatures. Professor @frediotto.bsky.social warns that El Niño is unfolding on an increasingly hotter, human-influenced climate baseline.

The study, published in The Lancet Regional Health - Europe and conducted by researchers from Imperial College London, the University of Turin, and the Lazio Regional Health Service, used nationwide data to analyse how heat-related deaths vary across socio-demographic groups and regions.

The findings highlight that heat adaptation plans must look beyond general temperature alerts to target specific vulnerable communities and disadvantaged local areas.

Future warnings: Glaciers and high altitude permafrost respond over decades to temperature rises. As such, past warming has already locked in future destabilisation increasing the urgency of fossil fuel phase outs to prevent future catastrophic collapses.

Adaptation limits exceeded: While Nepal has early warning systems and disaster roadmaps, the scale of this tragedy exceeded physical adaptation limits, highlighting the difficulty in adapting to worsening disasters and risk for greater loss and damage.

High temperatures and increased melt water: July and August 2026 - directly before the collapse - were the warmest on record locally. High snowfall in October and November 2025 added large amounts of melt water in the months preceding collapse.

Earthquake in 2015: Although its specific contribution to this disaster cannot yet be confirmed, a massive 7.8 magnitude earthquake in 2015 may have further contributed to the slope failure alongside other geological and climatic factors.

Permafrost thaw: Relentless warming has lifted the altitude of the freezing threshold on the high Himalaya, exposing ice and permafrost deep in the bedrock to higher and longer thaw temperatures, weakening mountain slopes.

15-day moving average height of 0°C isotherm at the approximate location of slope failure for each decade since 1980 over the glaciological year (October-September).

What the chart mostly shows is the 0 degree isotherm location for 2025/26 was consistently higher than the average across various decade periods from 1980 to the present and has on average risen decade-by-decade.

Glacier thinning: Warming has driven substantial glacier recession, removing stabilising ice from around the failure site, and contributing meltwater.

Dr Ben Clarke, Climate Change Researcher at Imperial College, said: “This disaster was not an extreme weather event, but the fingerprints of climate change are still clear to see in long-term changes. We found that climate change is [...] influencing many of the possible drivers of this collapse.”

Grantham Institute - Climate Change and the Environment @granthamicl.bsky.social · 17/09/2026

Rather than a single extreme weather event, scientists found that the disaster happened as a compound crisis. Decades of atmospheric warming - caused by burning fossil fuels - melted the glacier and thawed permafrost, making Langtang Lirung mountain more unstable and more likely to collapse.

$Visualisation showing five factors driven by climate change that may have contributed to the mountain collapse: 1. Permafrost degradation 2. Ice-filled fracture thaw 3. Glacier thinning 4. Increased meltwater 5. Heavier rainfall and higher rain-snow transition The visualisation also highlights the 2015 earthquake, which may also have made the mountain more unstable.$

6. Share your experiences with other teams conducting clinical trials Share your sustainability efforts & their impact with others, including how they enhance patient experience & reduce costs. Consider joining a community of practice like the Sustainable Clinical Trials COP: buff.ly/NElBqf7

5. Improve the environmental performance of your trial site Solar panels on roofs, buying energy from renewable sources, better insulated buildings and more energy efficient products all have an impact. Take part in programmes like the Laboratory Efficiency Assessment Framework: buff.ly/5tpgoxQ

4. Reduce waste Where waste is produced, it’s important to maximise recycling and minimise clinical waste. During the planning phase, use data and modelling to try to predict demand as accurately as possible. Identify other teams that could make use of leftover medication and equipment.

Grantham Institute - Climate Change and the Environment @granthamicl.bsky.social · 16/09/2026

3. Use more environmentally friendly medical products and procedures When possible choose materials that have a lower environmental impact. An MRI scan uses twice as much energy as a CT scan. The Lancet MedZero provides a great platform for emissions data: buff.ly/AWhCqMx

2. Minimise transport Transport is often the largest source of emissions across trials. Online appointments & research meetings can reduce costs, travel time & inconvenience for patients, & cut emissions. Plan in advance so that equipment can be transported by road or rail, rather than plane.

Globally, clinical trials are estimated to produce 100 million tonnes of carbon dioxide equivalent each year: equal to the carbon footprint of Belgium. The good news is that reducing the environmental impact of clinical trials often provides direct benefits to patients.
