Jurassic #fossil rewrites history of bird evolution reuters.com/science/jurassic-f

Earliest short-tailed bird from the Late #Jurassic of China nature.com/articles/s41586-024

"The newly identified bird, called #Baminornis zhenghensis, joins the similarly aged #Archaeopteryx as the oldest-known #birds. But Baminornis, about 15 cm long, was far more advanced anatomically and a better flier than crow-sized Archaeopteryx, a creature seemingly half #bird and half reptile."

Cretaceous #fossil from #Antarctica reveals earliest modern bird

#Cretaceous Antarctic bird skull elucidates early avian ecological diversity nature.com/articles/s41586-024

"Few #birds are as likely to start as many arguments among #paleontologists as #Vegavis. This new fossil is going to help resolve a lot of those arguments. Chief among them: where is Vegavis perched in the bird tree of life?"

#Fossil Discovery Rewrites Global #Dinosaur History sciencealert.com/fossil-discov paper: academic.oup.com/zoolinnean/ar

"Ahvaytum bahndooiveche is now the oldest-known dinosaur from #Laurasia, the Northern Hemisphere land mass of the late Paleozoic supercontinent #Pangea... That age places it in a similar time period to #dinosaurs of Pangea's Southern Hemisphere land mass, #Gondwana, which were thought to be the world's first by a long shot."

Discovery of rare new #fossil sheds light on #NewZealand's extinct dolphin-like reptiles phys.org/news/2025-01-discover

A platypterygiid #ichthyosaur from the #Cenomanian of central New Zealand tandfonline.com/doi/full/10.10

"This #discovery is particularly exciting because the specimen is about 98 million years old. This is about four million years before the final #extinction of #ichthyosaurs, which makes it one of the youngest semi-complete ichthyosaur skeletons known."

Dozens of massive #data #centers humming at the outskirts of Dublin are consuming more electricity than all of the urban homes in Ireland -- and starting to wear out the warm welcome that brought them here.

Now, a country that made itself a computing factory for Amazon, Google, Meta, Microsoft and TikTok
is wondering whether it was all worth it
as tech giants look around the world to build even more data centers to fuel the next wave of artificial intelligence.

Fears of rolling blackouts led Ireland’s grid operator to halt new data centers near Dublin until 2028.

These huge buildings and their powerful computers last year consumed 21% of the nation’s electricity, according to official records.

No other country has reported a higher burden to the International Energy Agency.

Not only that, but Ireland is still heavily reliant on burning #fossil #fuels to generate electricity,
despite a growing number of wind farms sprouting across the countryside.

Further data center expansion threatens Ireland’s goals to sharply cut planet-warming emissions.

Ireland is a “microcosm of what many countries could be facing over the next decade,
particularly with the growth of AI,”
said energy researcher Paul Deane of University College Cork.

"The life cycle emission intensity of solar solar photovoltaics is approximately 40 gC02/kWh."
- Zero CO2 emissions in the energy sector is therefore not currently possible in practice if we consider it globally and not just locally.
- If the EU were to buy these panels from #China then the emissions associated with the production and recycling of the panels would be shifted abroad and the EU would be seemingly "emission free" (but its territory is not under a glass lid).
- Although solar energy is significantly less carbon-intensive than coal or gas, it still produces carbon emissions.
- the key question is what the EU will pay for those imported solar panels with if, in time, the #BRIX countries reject the devaluing euro (devaluing for the very reason that the EU's economic problems are solved by issuing a new Euro, thus reducing its purchasing power)
- or will the EU manufacture the panels on its own territory? But from what, and how will it do it with zero emissions?

Wow. Klassevortrag von @thomasfricke ! Wenn ich da mal nachrechne komme ich auf diese Aussage: "Eine #KI mit gleich großer Rechenleistung (soweit möglich) verbraucht heute 1,6 Millionen mal soviel Energie wie das menschliche Gehirn."
Wer da auch Kühlung, Netzwerk, Clients, Hardwarebau und Rohstoffe einberechnen landet schnell im Milliardenbereich. Cui Bono? Big #fossil and #nuclear corporations.
