Regarding news articles today on a new paper linking the Black Death to post-volcanic cooling in the Mediterranean, our reconstruction shows it was cooler during that time (e.g. 1346 CE, following a 1345 tropical eruption) but not severely so (summer temperature anomalies vs. 1338-1340 CE baseline)

We did it by moving beads on the end of giant poles in the year of the pandemic (like the iconic images of women tracking the planes progress during ww2) to keep us apart but together. Added a dramatic edge to the differentiating magma.

Up to 30% of life, by weight, is underground. Seismic activity may renew the energy supply for subterranean ecosystems by exposing new rock and changing flow paths of water, expanding options for chemolithotrophic bacteria. In PNAS Nexus: https://ow.ly/tp4i50XzuoQ

🔴 ⚠️ 🌋 🛰️ Following the historical eruption of #HayliGubbi in #Ethiopia on Nov.23, changes are evident in the volcano with two new small craters, as seen in this before/after comparison of #Sentinel2 images,with also a large amount of ash covering the old lava field. #copernicus

Fascinating and timely work on the intrusion that preceded the #HayliGubbi eruption - this will turn out to be a very valuable example for volcanologists!

Alessandro La Rosa @alarosa.bsky.social · 12d

The #HayliGubbi eruption came after a period of unrest that started in June-July 2025 with a large dike intrusion in the southern sector of the Erta Ale rift. Our InSAR study will be out soon but you can have a summary at the link below. @earth-science.bsky.social #geoscience

Quick TV recommendation for anyone looking for something warm, slow, gentle, and wise:

You'll know from the trailer if this is one for you, which is handy.

I watched the Brazil '98 match in The Shakespeare Pub in San Diego, which had opened especially to attract "the Scottish crowd". Kick off was about 8am PST and my mate Stuart (who was visiting) and I wore our kilts. Just us and the barman were there. Still bedlam when John Collins's scored!

Duncan Lamont @duncanlamont2.bsky.social · 18d

The last time Scotland was at a World Cup I watched the opening match against Brazil in my mum’s living room with my mates and a crate of Tennents

Scotland scored to make it 1-1

Everyone ran into the street screaming, neighbours hugging each other

Can still remember that feeling. Here. We. Go.
