Europe didnt just experience an exceptionally hot summer in 2026. It experienced a summer where multiple climate extremes reinforced each other. First - temperature records were broken at daily, monthly and seasonal scales across Europe Read more: climate.copernicus.eu/summer-revie...

Another "need to extend the y-axis" moment... Average temperature in Central England for Jan-Sep for each year since 1772. It is 0.8°C higher in 2026 than any other previous year.

"Pricing El Niño is not the same as preventing its loss of life. Yet, many of those acting on its forecasts are using them to move money, not people, out of harm’s way." My editorial for Science on why hedging El Niño is not the same as adapting to it: www.science.org/eprint/DU6FR...

Hedging El Niño isn’t the same as adapting to it

Counterintuitively, mixing of dry air into convecting plumes amplifies moist heat extremes. This "entrainment" effect strengthens as climate warms and dries, increasing human heat stress. Details in our new paper, led by @roshanjha.bsky.social: agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Is the European 2026 drought unprecedented in the last millennium? An answer based on the recently published Master thesis work by Patricia Helpap: geco-group.org/post/pcwd_20...

Projection has become reality 22 years ago, Christoph Schär et al. published a landmark paper in Nature explaining that the 2003 heatwave was a harbinger of things to come. The study featured an iconic figure - shown in countless lectures - illustrating how outlandish the event was at the time

With the looming El Nino, what does this mean for UK weather? Likely wet? The major El Nino events of the last 50 years have all been coincident with a wet UK in late autumn into winter. The wetter winter part did not occur during the 1877-78 El Nino, which we think was the largest event on record.

Warming temperatures + decreasing relative humidity = more water being sucked from soil / reservoirs = DROUGHT. Simple physics. Europe + UK are on the frontline because they are warming so rapidly – it will get worse until 'net zero' is reached. That's my TED talk 🌍 www.bbc.co.uk/news/live/cw...

Bordeaux, France, has now recorded more days above 40°C in 2026 alone than during the entire 105-year period from 1920 (when observations began) to 2025. This is deeply shocking.

Human-induced climate change made the extreme fire weather that fuelled the recent destructive wildfires at least twice as likely in France and at least 20 times more likely in Spain, according to our new study.

A wildfire can be explained by today’s barbecue, yesterday’s wind direction, a dry spring, four decades of land use change, or a century of emissions.

Why Europe, the world’s fastest-warming continent, was primed to burn this summer

The continent has warmed twice as fast as the rest of the globe over the last 30 years. The fires in France and Spain are a consequence of the extreme heat, which dried out vegetation.

Scientists warned you about: ♨️ more/longer/hotter heatwaves (hot planet=hot weather) 🌀 stronger storms (warm water=hurricane food) 🌧️ downpours (warm air holds more water vapor) 🌵 droughts (warm air is thirstier) 🔥 fire weather (hotter, drier) 🌊 sea level rise (land ice melts, warm water expands)
