Actually, I am going to write someday a short post "time machine as existential risk".
Technically, any time travel is possible only if timeline is branching, but it is ok in quantum multiverse. However, some changes in the past will be invariants: they will not change the future in the way that causes ground father paradox. Such invariants will be loopholes and have very high measure. UFO could be such invariants and this explains their strangeness: only strange thing are not changing future ti prevent their own existence.
The report doesn't mention any likelihood of any of these events happening
May be you discuss a different report than I read. The one I read says:
In fact there is evidence of eruptions at Kivu in about 1000 year cycles and predictions based on observed accumulation rates (10-14% per year) suggest an eruption in the next 100-200 years, see Report [1].
Chips. While China chip industry is getting sanctioned, most of the world production of advanced chip remains on Taiwan. But this is not for long, as manufacturing start relocating in other places. Attack on Taiwan could prevent US dominance in chips and AI.
Ukraine war strained US production of some weapons, but US invested in increase of production of missiles and artillery ships. So in future situation will be less advantageous for war.
China has clear advantage now in cheap drones produced in mass, like DJI. But is is also not for long.
How much are electricity, maintenance and property tax for this venue? Historic building may require expensive restoration and are subject to complex regulation.
One thing that he didn't use in his EV calculations is meta-level impact of failure on the popularity of EA and utilitarianism. Even relatively small failure in money could have almost infinite negative utility if topics like x-risks prevention become very unpopular.
I am interested to see how wood gasification s an energy source for cars could be bootstrapped in the case of industry collapse.
Another topic: how some cold tolerant crops from nothern regions ( fodder beet, rutabaga) could be planted in South in the case of nuclear war winter. I already tried some experiment remotely (asked friend) but it failed.
Also creating self-sustaing community on an island would be an interesting experiment.
The relation between warming and CO2 is exponential, s we need to count the number of doublings of CO2. Every doubling gives a constant increase of the temperature. Assuming that each doubling gives 2C and 22= 2exp4.5, we get around 9C above preindustrial level before we reach tipping point.
In the article the tipping point is above 4C (in the chart) plus 6C from warmer world = 10C, which gives us approximately the same result as I calculated above.
It also happens in personal life.

Thanks for these details!

Three arguments in favor of war soon:
And did the purchase come with any conditions, like the right for the billionaire to use the venue as his house between the conferences?
