Climate

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

The heat index (temperature and humidity combined) reached 48°C (118°F) in parts of the Philippines this past week. Thankfully, April and May are relatively dry months.

I do expect that we’ll collectively get much more acquainted with the concept of unsafe wet bulb temperatures over the next few years

Increasing wildfires and methane leaking from glacial melt are huge problems that are not being fully considered in most climate scenarios. Also, much harder to stop, even if we drastically cut emissions now.

Yep, runways will have to be longer in the future...

Ah yes, reminds me of the terrifying opening chapter of Ministry of the Future

jokes aside, it's terrible what's happening with the climate. I don't remember a summer having so persistent high temperatures as the current summer...

Got it. I’m considering that europeans and americans are highly susceptible to temp changes, we are used to 42 celsius and bad conditions but put it in france and see chaos happens

Why wouldn’t planting trees be enough? and also, do you have an idea of how we haven’t been able to create synthetically a molecule that binds to CO2?

If I was to create something I’d try to research blood compounds, hemoglobin specifically. Since it binds strongly to CO2. In this case, couldn’t we use blood (from cattle, for example) to neutralize emissions? 

OR, create a synthetically analogue to hemoglobin?

my scientist mind wanders a lot

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

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?
