Fascinating mystery of the first farmers in Europe, and how they turned (or did they?) to violence... (and also about headless corpses)

Headless bodies hint at why Europe’s first farmers vanished

Wave of mass brutality accompanied the collapse of the first pan-European culture

The biggest misunderstanding of Carbon Dioxide Removal (CDR), IMHO, is that many assume it is a replacement for emissions reductions. As in, more CDR, less emission reductions. No. Emissions need to go down as fast as possible, even faster, no matter how much (~feasible) CDR you have.

In a potentially dramatic change to how it chooses what science to fund, NIH is ending a long-running practice at many of its institutes of establishing, and making public, a threshold peer-review score needed for a grant application’s approval. https://scim.ag/48ck2zu

NIH shake-up to grant decision-making draws concerns of political meddling

Policy drops “paylines” based on peer-review scores and requires geography and other factors to guide approvals

Uhh... this whole banking on Germany to be the military backbone for Europe (with less US)... may not have been thought through. At least no one told the Germans.

POLITICO Europe @politico.eu · 2d

You can even put an exact date on the day when Brussels finally gave up on its decade-long dream of seeking to be the predominant global tech regulator that would rein in American tech titans like Google and Apple.

It came last Wednesday — Nov. 19.

Brussels is done being the world’s digital policeman

The “Brussels Effect” is dead. Now Washington is setting the pace on deregulation in Europe.

Turns out that sucking CO2 from air is fairly expensive and not easy (and we won't be able to do it at the scale that is needed to ease CO2 emissions in any great quantity at timescales needed). Curbing CO2 emissions is the easiest and fastest way, if we can just agree on it as a society...

Dr. Aaron Thierry @thierryaaron.bsky.social · 2d

"The cost of removing large quantities of CO2 from the air will fall in the medium term, but not as much as previously hoped.

This is the conclusion reached by @ethz.ch researchers on the basis of new calculations. Efforts to reduce carbon emissions should therefore continue at pace"

LLMs are fast becoming a major source of information.

In a new piece over at The Climate Brink, I argue that LLMs are fundamentally consensus machines, and could help defragment our information ecosystem – at least if their creators do not put thumbs on the digital scale.

The hard truth is that overshoot is really really hard to get to also..

Glen Peters @glenpeters.bsky.social · 3d

Now that we are likely to cross 1.5°C, there is increasing discussion on "overshoot".

There is a lot of uncertainties on overshoot, but there is one thing that we are 100% sure about:

GHG emissions need to go down >90% in decades for overshoot to be a reality.

www.swp-berlin.org/publikation/...

Glen Peters @glenpeters.bsky.social · 3d

And if IPCC AR7 is not released until after the GST in 2028, then they will still be using the 2019 number until 2029, when the budget for 1.5°C would have been exceeded...

(unless someone comes up with new bigger budgets)

Ben Sanderson @benmsanderson.bsky.social · 4d

#cop30 decision's "recalling with concern" that "historical cumulative net carbon dioxide emissions account for at least four fifths of the total carbon budget for a 50% probability of limiting global warming to 1.5C" was true *in 2019*.

It's now 94%, best guess. /1
