Some years ago the Danish meteorological society (full disclosure, I sit on the board) held an evening debate on cloud seeding, based on a film from the middle east and with a scientist from Israel who had been assessing experiments for many years. He was extremely sceptical it worked. I think I reached very similar conclusions to this excellent piece in #theclimatebrink. Cloud seeding can work under very specific conditions, but it's mostly a scam.

A neat deep time framing device from Peter Brannen:
- A moderately intense walking cadence is 100 steps per minute.
- Imagine that with each step you are stepping back 100 years…

After 20 steps in 12 seconds you are back to the time of Jesus Christ.

After half an hour you’re back to the beginning of Homo Sapiens.

Let’s say you do the classic 10k steps per day.

At that rate, it’ll take you 66 days to reach the Cretaceous–Paleogene (K–Pg) extinction event which wiped out the dinosaurs…
