What places on Earth are most resilient to global catastrophic risk? Our new review in Global Challenges is the first study to look at this across nuclear war, near-Earth objects, large volcanic eruptions, cyberattacks, high altitude electromagnetic pulse […] [Original post on fediscience.org]

The failure of the food system is what gets you in almost every global catastrophe scenario. Research on making it resilient is underfunded relative to that importance. I spoke about this at the World Adaptation Forum in Budapest earlier this year. The […] [Original post on fediscience.org]

You might remember the warnings about the ozone hole, about skin cancer and eye damage on a huge scale. You don't hear about it anymore because it largely worked. Almost all ozone depleting substances have been phased out and the ozone layer is on track to […] [Original post on fediscience.org]

What happens to Europe if the AMOC collapses? The potential for much colder winters, loss of a significant part of maize and wheat agriculture, UK farmland reverting to grassland. The IPCC's confidence that this won't happen this century has decreased. In my […] [Original post on fediscience.org]

You are likely familiar with visions of doom. When I look at the news, at blog posts, at conference abstracts, all everyone ever talks about is some shade of the world ending. And I would not even necessarily disagree with them. Many things are not […] [Original post on fediscience.org]

Nuclear war is horrible and I hope it never happens. Yet, there are only a few countries that actually have nuclear weapons and the power to use them is concentrated in just a few individuals. This means the vast majority of the global population has no say […] [Original post on fediscience.org]

Take a guess at how many civil protection bunkers currently exist in working condition in Germany. See the first comment for the answer. The reason I'm asking is that I wrote a summary on the state of civil protection bunkers in Germany, which you can find […] [Original post on fediscience.org]

New update post for my living literature review on societal collapse: https://existentialcrunch.substack.com/p/april-2026-updates This means I go back to the old posts and add new papers I found, to make sure that everything stays as up to date as possible […] [Original post on fediscience.org]

New preprint! We reviewed global catastrophic risks: nuclear war, volcanic eruptions, asteroid impacts, cyberattacks, EMP, geomagnetic storms, and pandemics. Which places on Earth are most resilient? The short answer: nowhere is safe from everything […] [Original post on fediscience.org]

New preprint! Global inequality is on the rise, and so is global catastrophic risk. These two problems are not independent: inequality drives societal instability and increases catastrophic risk. We show this by drawing on historical and empirical research […] [Original post on fediscience.org]

Who actually shapes global risk? One common answer is to focus on individual apocalyptic actors, like terrorists aiming to end the world. But are these groups really what we should be on the lookout for most? Or should we not also consider institutional […] [Original post on fediscience.org]

New post about the state of research around nuclear war and nuclear winter, with a focus on the food system. This one's a bit different, as it was originally an invited contribution to the United Nations Independent Scientific Panel on the Effects of Nuclear […] [Original post on fediscience.org]

‘AltMetric’-style services, which track citations to academic papers outside of academic literature—so in the news, social media, etc.—have been quick to incorporate #BlueSky posts, but I’ve yet to see one that includes the #fediverse I can see that (real) decentralisation makes it harder to […]

New paper is out! We identified the worst crop shock every country experienced since 1961: the global average was −29%, with Botswana even losing 80% in a single year. Climate—especially drought—was the leading cause, although conflict is also a major […] [Original post on fediscience.org]

One important factor to understanding the impact of global catastrophes is economics. How might agricultural prices rise? What are the general economic outlooks? In the next post in my living literature review I try to explore exactly this. The literature is […] [Original post on fediscience.org]
