11/09/2026The Inaugural Sir Crispin Tickell Memorial Lecture, by Jeremy Leggett.
Sir Crispin Tickell convinced Margaret Thatcher that global warming needed urgent attention. His knowledge and advocacy played a pivotal role in tackling climate change. How would he have tackled AI?
For the first half of this lecture, the words are not Jeremy Leggett's. He put three questions to Claude AI, about the danger of AI itself, and about what Crispin would have made of it. In the second half he answers the same questions himself.
Fifty minutes, filmed at St Mary's, Bibury. The full text, with both sets of answers, is in the post below.

"Ambitious for Scotland": Thoughts on the Scottish Government’s Programme for Government 2026-31, from the Founder of a company positioning to help.

£800k bridge target, more than half way there. Three months on from the launch of NatureProsperity - Jeremy Leggett gives an update and tells us what’s next.
Forty years of warnings, six tonnes at a time
Burning summer reflections, from Jeremy Leggett. From where I am staying beside the Rhone in Provence, it feels like living at the end of a bomber-base runway in the Second World War. Smoke stands on the ridges to the south. Every few minutes another of the yellow Canadairs drops out of the glare, flattens out low over the river, and ploughs a long white furrow across it, ramming six tonnes of water into its tanks without ever quite landing.
A Tale of Two Economies
In his Scotsman op-ed, NatureProsperity Founder Jeremy Leggett sets out the case for a new kind of economy: one built on nature recovery, not extraction. He introduces the nature prosperity pump and explains why it offers a credible path to ecological and social resilience at scale.

Founder’s Note: Introducing NatureProsperity
Much of Scotland’s economy is rural, and lurking in that economy - waiting to be awakened - is something I think of as the Nature Prosperity Pump. This is no ordinary pump. It has the ability to dismantle three existential threats to the Scottish economy: climate meltdown, biodiversity collapse, and the national housing emergency, a.k.a the national dearth of affordable housing.
