Remember the beautiful auroras last year? These occur when solar particles interact with Earth's magnetic field. When #Earth is hit by large amounts of these particles, this is called a #GeomagneticStorm. Geomagnetic storms can induce currents into the […] [Original post on fediscience.org]

I have written a new draft for my blog about the potential damages that can be caused by a #geomagneticstorm. I am looking for someone familiar with this topic to review it for accuracy. If this is you, please write me a message. If this is not you, please consider boosting this message.

New post on my blog. I summarized Peter Turchin's book "End Times: Elites, Counter-Elites, and the Path of Political Disintegration". The post gives an overview of how #StructuralDemographicTheory works and how this explains the present political and social […] [Original post on fediscience.org]

(1/4) We modeled how global food trade would collapse after catastrophic events like nuclear war or infrastructure loss. It matters enormously where damage occurs, not just how much. Especially, in nuclear winter many countries would loose the majority of […] [Original post on fediscience.org]

#ClimateChange, #NuclearWinter, and #StratosphericAerosolInjection are all human-made interventions in the climate system. They share the potential to be massively disruptive to the habitability of this planet. Usually, we see them as separate catastrophes […] [Original post on fediscience.org]

Der wichtigste Gedanke, wenn mal wieder berichtet wird, dass die Bahn „Verluste“ macht: Wie hoch sind doch gleich die jährlichen Gewinne im Bundeshaushalt durch den Betrieb der Autobahnen?

Have been doing some nature photography for the last two years or so. Was thinking about sharing a few here. Starting with one of my favorites. This very cute little #mouse. #nature #photography

New paper is out: The State of Global Catastrophic Risk Research: A Bibliometric Review. I am quite happy with this one. I think the paper gives a nice overview of what people in the global catastrophic risk community think about and what their research […] [Original post on fediscience.org]

Can really recommend to go hiking along the #rhine

Time for updates on my blog again. However, not only the articles, but also the infrastructure. Thanks to @rogue_scholar now every post has a DOI and can be cited. Also, to make things look nicer, every post now has its on fitting picture at the start. When […] [Original post on fediscience.org]

To prepare you need to know what you might face. This is true for an individual, as well as a society. To make it a bit easier to figure this out on a societal level, I aggregated a number of sources that try to assess what challenges humanity might face […] [Original post on fediscience.org]

In the research around #SocietalCollapse, once you get to the 18th century, revolutions start to pop up as a topic. To better understand the ideas and concepts important for revolutions, I read and summarized Hannah Arendt's "On #Revolution". In this she […] [Original post on fediscience.org]

Does anyone know how the new #Pebble watches will handle data privacy?

I am currently writing my first research grant for the #dfg and I was wondering what is expected to me in the "preliminary work" section. Is this more about relevant work I have published in the past, work that I have done for this specific idea which is not published yet, both or something […]

The EU should jump at the opportunity to take over frozen and/or defunded USAID programs. You'll never get the chance to have this much data on outcomes before making a funding decision in foreign aid! https://citizens.ec.europa.eu/participation/processes/mmf/f/68/proposals/6370

I finally gave Facebook and the whole Meta suite the flick. And I feel lighter! I've been working through 'The Cyber-Cleanse' by Janet Vertesi @cyberlyra. https://www.optoutproject.net/tags/cleanse/ I started ahead in some regards, am behind in others, and some things either don't apply to me […]

Hi! If you are new here (no matter where you come from): welcome! This place can be a bit rough around the edges (and there is often quiet a bit of friendly fire going on), but it's worth sticking around and trying to build something decentralised and fun and hopefully independent. You can […]

During my research around #SocietalCollapse, one thing that comes up again and is economic #inequality. It seems that there is something about it that makes societies inherently less stable and less able to tackle challenges ahead. To explore this more, I […] [Original post on fediscience.org]

In the last few days the news focused a lot on the fact that #2024 was the first year where we went above #1.5°C. This made me want to highlight a paper again where I was the main author in 2022. In this paper we looked at what temperatures the #IPCC reports […] [Original post on fediscience.org]

Update. #ai / #LLMs "tend to recommend literature with greater citation counts, later publication date, and larger author teams. Yet, in scholar recommendation tasks, there is no evidence that LLMs disproportionately recommend male, white, or developed-country authors, contrasting with patterns […]
