Went for a walk on Dartmoor yesterday & found these little water spouts bubbling up in a place that's bone dry in Spring & Summer. Today, an ecologist has explained to me these are 'ephemeral springs': where the bedrock on Dartmoor is impermeable granite, the water can't sink past the bedrock.

Another John Martin-style #paleoart piece painted for fun. This riffs on 1830s views of the British Wealden, where giant dinosaurs (Iguanodon and Megalosaurus here) engaged in violent combat in grand natural amphitheatres. Pterosaurs and other animals watch on. ARE YOU NOT ENTERTAINED? #sciart

NB global sea levels have risen by c.10 cm (4“) since 1990, and the rate is now accelerating to >4 mm / year.

What's our long-term strategy for coastal cities: protection, mitigation, denial of risk?

"Once citizens understand that ecological collapse threatens food security, migration stability, economic resilience and peace, pressure for meaningful action becomes unavoidable".
Originally presented at COBRA, this report shows that ecosystem collapse is a strategic emergency capable of destabilising entire regions and food systems. Rupert Read reviews a shocking new government assessment.

A suppressed warning finally appears: ecosystem collapse as a national security threat
A government report on the national security implications of ecosystem collapse is finally out, and it’s even more shocking than feared

Can anyone out there help me to identify these little spotty ovals that I am finding in pond sediment samples? They look like miniature leaves on a little stalk..in some samples I have 100 and in others I have none. Wondered if they might be something fungal rather than plant related. Any thoughts?

Part of the Line Ponds on Skipwith Common in Vale of York. These are where flax would be retted (soaked) to extract the fibre for spinning into linen. Retting flax or hemp was a polluting activity, kept away from village water supplies. 'Tow dykes' elsewhere on the Common had a similar function.

This is a truly horrifying account of increasingly likely collapse of essential natural systems which would bring mass food shortages, price rises & global disorder. Commissioned from UK intelligence chiefs but scandalously suppressed by Govt, & sneaked out now while attention is elsewhere 👇
