Here’s the monthly data with a 12-month trailing average, so we don’t “look ahead” of the time series. We can see that visits from Canada are substantially down. Like, a *lot*. And if we looked at the French series by itself we’d see something too. But it’s not on the scale of Covid. Yet.
Smoothed monthly graph shows Canada has dropped in visits substantially, but not to the extent we saw in Covid

My book, *The Carbon Wave*, is the #1 new release in Environmental Policy! Thanks to everyone who has picked up a copy so far. My deepest hope is that this book will catalyze a lot of new climate action, so thanks for sharing it with others. Really appreciate all the support!

This is the far more likely pathway for how AI will end us all, btw. Not via some superintelligent swarm of paperclip maximizers, but by a cascading sequence of dumb fuckups driven by human beings who have arranged things to be fast-moving and catastrophically fragile while also being really lazy.

When the Paris Agreement goals was negotiated in 2016, targets were set based on what was feasible at the time. A stark takeaway from today's UNEP 'overshoot' report is that we fucked it up. We didn't do the things we needed to do. We wasted a decade and the consequences are coming.

European summers aren't what they used to be! Grey curve is the climate of 1950-90. Every coloured line is a summer since 1991. Every one since 2005 sits beyond the 95th percentile of the curve. This isn't a shifting #climate. It's already a new one! 🤯🥵 Plot inspired by Barriopedro et al. 2011
Distribution of European summer temperature anomalies, June to August, over 25°W-40°E, 35-70°N, land only, the region used by Barriopedro et al., relative to 1961-1990, from ERA5. Grey bars show the 41 summers from 1950 to 1990, with a normal curve fitted through them, centred near zero. Coloured vertical lines show every summer from 1991 to 2025, shaded yellow through dark red by year, and almost all of them fall to the right of the grey distribution. The ten warmest are labelled, with 2024 furthest right at 2.74°C and 2022 next at 2.54°C. A dotted line marks the 95th percentile of the 1950-1990 distribution at 0.76°C.

Both run long, which is fine, since alt text has no practical limit and screen reader users benefit from the detail.

A first year above 2C in the mid-2030s now looks plausible. 0.5C was first passed in 1980, 1.0C in 2010 and 1.5C in 2024. The 15-year trend runs at 0.42C per decade. The 2026 and 2027 points for the current El Nino are estimates. We're not remotely ready!
Line chart titled "A first year above 2 C in the mid-2030s looks increasingly plausible". It shows global mean surface temperature from 1940 to 2050 as the annual anomaly against the 1850 to 1900 baseline, in degrees C. Data is ERA5 from Copernicus, running to 31 July 2026.

A thin gold line shows individual years, wobbling around a thick dark blue smoothed trend. Both sit near 0.2 C through the 1940s to the early 1970s, then climb steadily from the mid-1970s onward.

Three red dots mark the first year each threshold was passed. 0.5 C in 1980, 1.0 C in 2010 and 1.5 C in 2024. Labels beneath note the gap of 30 years between the first two and 14 years between the second and third. Everything above 1.5 C is shaded pink.

Two dashed lines run forward from 2025. A blue line follows the 15-year trend of 0.42 C per decade and reaches 2 C in 2037. A fainter grey line follows the 30-year trend of 0.27 C per decade and reaches 2 C in 2044.

Two orange circles mark estimates for the developing El Niño, at about 1.5 C for 2026 and about 1.7 C for 2027.

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.

Think of CO₂ removal like a time machine. How far back does planting 100 million trees take us? One mature tree takes up ~25 kg of CO₂/year, so 100 million trees will take up 2.5 MtCO₂. That's a time machine that takes us back ~33 minutes in a year. Nature will not save us from fossil fuel CO₂.

Denmark's coal-to-wind transition is one of the most dramatic energy transformations of the past three decades. In 1990, coal provided 90% of Danish electricity. Today it is under 3%. Wind now covers roughly 60% of electricity generation. The last coal plant is scheduled to close by 2028.
