PFAS “forever chemicals” have now been found in record levels in whales and dolphins.
Once we create these substances, they stay in our environment indefinitely. We urgently need stronger controls on the chemical industry and a shift to safer alternatives.

I remain opposed to a third runway at Heathrow because of the severe impact it would have on noise, pollution and climate targets.

With a return to the Pliocene locked-in, the only meaningful question is, will we stop there or maintain BAU until a return to the Middle Miocene becomes inevitable or - ultimately - the early Eocene?
If the latter, this is what the UK will eventually look like

"I walked in the North Holland dunes on Sunday, outside the contours. It was a constant racket from a steady stream of low-flying aircraft. Not being able to experience more relative silence anywhere else is a greatly underestimated problem, on top of the noise pollution in and around the house."
Zondag gewandeld in de NH duinen, buiten de contouren. Eén en al takkeherrie van een gestage stroom laagvliegende toestellen, zoals meestal. Nergens in je omgeving meer relatieve stilte kunnen ervaren is zeer onderschat probleem, bovenop de geluidsoverlast in en om de woning.
