Yes, James Lovelock wrote The Ages of Gaia, I think, in 1988. It wasn't his first Gaia book, but it is probably the best written one. I have just been re-reading it recently and certain themes that he picked up on are ones that are still considered novel today. Not just the whole idea of the way the earth works, almost as a living organism. But also looking at the way humanity is going to have to reconcile itself with the constraints and the limits of the planet.
It says how long ago something was said, so you can tell last month

drains and cools as the date gets older, and empties completely at about
6 years.

A striped bar means the date itself is an estimate — the source did
not carry an exact one. An entry with no date at all gets no bar.
