Welp, looks like an airport in Iran just recorded a heat index (i.e., perceived temperature) of 180°F / 82.2°C, which is well into the “red zone” of the chart below. The air temperature of 102°F / 38.9°C combined with a humidity of 85% led to that record-breaking heat index. This is the first time I see a wet-bulb temperature excursion into lethal territory. Wait until this happens in a place like Delhi. We’re just casually speedrunning the Great Filter Source: https://x.com/US_Stormwatch/status/1828905915225125132

I have a question. Let’s consider we have extreme warming and temps increase 1-2 celsius then weather goes crazy more heat and cold waves so most fragile pop dies (let’s say 20%) and fertility rates decrease would that 20% of elder & children death be enough for us to become below the maximum support capacity and weather becomes nice again? OR is the ozone layer hole irreversibly fucked?

It’s a bleak but great question. My view is that the most vulnerable populations reside in places where the CO2 emissions per capita are also the smallest due to low standards of living (Africa, Central Asia, Indian subcontinent). So the effects of mass casualties there on global CO2 emissions will be limited. Conversely, the countries with a high CO2 footprint are also those that can generally delay the effects of lethal heat (proper building insulation, air conditioning, robust electrical grid, running water). So they will continue to output CO2 as usual. There’s also a considerable inertia in the system. CO2 can linger in the atmosphere for centuries or more. It’s entirely possible that we cross a catastrophic threshold without knowing it, especially as feedback loops and tipping points occur (e.g., the clathrate gun hypothesis). In which case even if enough of humanity was rendered unable to keep releasing CO2, the rest would be doomed just from the inertia by which warming will continue anyway

@aviationdoctor.eth is right. Even if the entire populations of Africa, India AND South America just die, emissions that impact climate from China, USA and Europe will keep harming the environment. I'm a fatalist, I know but I don't think there's a reverse to this situation. And people in rich countries will just adapt and keep not caring about it. Just stay at home for most of the time, and build enormous shopping centers with trees inside.

(Also the issue here is not with the ozone layer but purely atmospheric greenhouse gases and the radiative forcing that they cause)

We need ASI asap. It sounds absurd, more energy usage, but I think we are past a tipping point. All this assumes our collapsing societal institutions will allow us enough time to do anything.
