It’s now official: June–July 2026 was the most anomalously warm two-month period ever recorded in France by a staggering margin. France is now virtually certain to record its warmest summer on record.

When @granthamicl.bsky.social estimated 2,700 deaths from these heatwaves, some in the media called it scaremongering. Today, UKHSA analysis of observed deaths sadly confirms the scale of the impact. We can't ignore the health threats posed by climate change. www.theguardian.com/environment/...

England on track for record heat-related deaths this summer, official data shows

UKHSA estimates 2,877 fatalities during heatwaves in May and June, almost twice that recorded in 2025 season

All the people who are saying it's too expensive to tackle climate change today are the same people who twenty years ago said that climate change wasn't really happening

What is the future of summers in England? Our choices matter. A high-emissions future will commit our children and grandchildren to live in a world where the summers of 1976 & 2025 are cold. A global net-zero emissions future means that we can stabilise the climate & those summers will be normal.

NEW: The brilliant scientists at WWA have just published a study on the European heatwave: 🌍 Climate change “unequivocally to blame”. 🔥 The peak temps “virtually impossible” 50 years ago. 🌙 The overnight temps “100x more likely” now than in 2003. 👉 www.worldweatherattribution.org/fossil-fuel-...

There's a reason we’re suffering such dangerous heat; it’s not natural, it’s us. Until we stop dumping greenhouse gasses in the atmosphere, weather extremes will just keep getting worse. It's not complicated but too often our broadcasters fail to connect the dots. That does a disservice to us all.

++BREAKING++ Leading climate scientists in the UK have written to senior editors in broadcast media - and OFCOM and IPSO: "To express our concern about recent media coverage of extreme weather, climate change and net-zero and to urge you…to inform public audiences of the scientific links"

Letter in today's Times by climate scientist Sir Brian Hoskins: "The discourse around net-zero is increasingly decoupled from…science and our changing weather. "Net-zero is not an arbitrary slogan, rather it is dictated by the laws of physics."

Happy birthday to the heatwave of 1976 which began today 50 years ago, peaking at 35.9°C. If a comparable heatwave happened in the current climate it would be 3-4°C hotter, peaking at 38-39°C. And the actual forecast is for temperatures of 38-39°C in the next few days with a red heatwave warning.

The summer of 1976 translated into a warmer climate.

This Inside Story on #AirPollution from @granthamicl.bsky.social is well worth a watch. The film features our volunteer Beth, who has a young child with lung problems, speaking about the impact on her family. "I can't go to work as a doctor, because my own child is impacted by the air quality".

Inside Story: The fight to clean up London’s air

This is a story about why air pollution is a public health issue, how making invisible pollution visible led to cleaner air, and why the fight now is to ensure everyone benefits equally. Hear…

Hard to believe I’m even writing this. Meteorological summer hasn’t even begun, yet Paris, France has already logged more days above 32°C than its annual average.

34.8ºC at Kew Gardens breaks its May AND June records by OVER 4ºC for its May record set in 1922 and by 0.2ºC for its June record set in 1976. Unprecedented heat for the UK in late May, and likely to be bettered tomorrow. A rounded 35ºC temperature should not happen in May.

Spaghetti plot showing Kew and Kew Gardens temperatures since 1881 with May and June records highlighted at 30.3ºC in 1922 and 34.6ºC in 1976 respectively. 2026 is plotted as a thick red line that nearly exceeds 35ºC with a value of 34.8ºC.

Europe is the world’s fastest-warming continent. We’ve seen record heatwaves from the Mediterranean to the Arctic, while glaciers have been shrinking and snow cover melting. The evidence is unequivocal: climate change is not a ‘future’ threat. It is our present reality. ⬇️

A circular map of Europe and the Arctic region showing the rate of warming from 1996 to 2025, measured in degrees Celsius per decade. Most of Europe is shaded in orange to deep red, indicating significant warming, especially in Eastern Europe and parts of Scandinavia. The Arctic region north of Scandinavia and Russia is the darkest red, showing the fastest warming. Greenland shows mixed colors, with some areas in light tones and patches of blue, indicating little warming or slight cooling. The North Atlantic west of Europe appears in pale colors and light blue, suggesting slower warming or localized cooling. A color bar at the bottom ranges from dark blue (cooling, about -1.5°C per decade) to dark red (warming, about +1.5°C per decade).
