A new Hollywood film (Pressure) is to be released shortly to tell the story of the infamous weather forecast that enabled D-Day to be a success. We produced a new reanalysis for D-Day, and processed it to look a bit like a satellite image. climatelabbook.substack.com/p/pressure-t...

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.

Komorebi is a single-word lexicalization for "sunlight filtering through leaves" and that's a lovely concept I'm enjoying having learned about today despite (and indeed because of) how extremely translatable it is www.morethantokyo.com/komorebi-jap...
It is formed from the Japanese word for “tree,” 木, the word that means “to leak,” 漏れ, and the word for “sun,” 日.

Komorebi 木漏れ日 (pronounced kō-mō-leh-bē)

Literally, “sunlight leaking through trees,” this word describes the beauty and wonder of rays of light dappling through overhead leaves, casting dancing shadows on the forest floor.

Just one possible outcome... but the GFS weather forecast model is suggesting 40-41°C is possible in the UK around 7th July. This is a long-range forecast with significant uncertainty, but the fact that we are even seeing such values fairly regularly in the forecasts is extraordinary.

I think a lot about what Carl Sagan said in one of his final interviews.
"WE'VE ARRANGED A society based on science and technology, in which nobody understands anything about science technology. And this combustible mixture of ignorance and power, sooner or later, is going to blow up in our faces. Who is running the science and technology in a democracy if the people don't know anything about it?"
"Science is more than a body of knowledge, it's a way of thinking. A way of skeptically interrogating the universe with a fine understanding of human fallibility. If we are not able to ask skeptical questions, to interrogate those who tell us that something is true, to be skeptical of those in authority, then we're up for grabs for the next charlatan, political or religious, who comes ambling along."
