Temperatures above 50C used to be a rarity confined to two or three global hotspots, but the World Meteorological Organization noted that at least 10 countries have reported this level of searing heat in the past year: the US, Mexico, Morocco, Algeria, Saudi Arabia, Kuwait, Iran, Pakistan, India and China.
In Iran, the heat index – a measure that also includes humidity – has come perilously close to 60C, far above the level considered safe for humans.
Heatwaves are now commonplace elsewhere, killing the most vulnerable, worsening inequality and threatening the wellbeing of future generations. Unicef calculates a quarter of the world’s children are already exposed to frequent heatwaves, and this will rise to almost 100% by mid-century.
This is certainly a credible assertion, but it’s very broad.
As in, runaway elitism is probably relevant to almost all civilisation-ending catastrophes.
I don’t know exactly what to call it and I don’t want to sound like my agenda is just anti-capitalism. For a brief, 250yr period, humanity (not all, but enough of) valued science and reasoned law as the highest, most advanced expressions of our civilization. The enlightenment age brought about modernity as we know it based on science and liberal law (no kings above the law). Now we’ve devolved back to every nation basically establishing new oligarchich aristocracies no law can touch (the historic normal), and it’s definitely too late to correct course. No untouchable nobilities or kings will save this realm. So yeah, the great filter in my view is about letting elites be accountable to no one, with no interest other than accretion, rule things into the ground. And yeah that’s the broad gist of my point about a pretty broad theory. Most think the great filter as an asteroid or nuke. For me it’s runaway elitism that probably ends most civilizations which is why there’s no one out there.
