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.

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

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

Why do you think the French sold it to the Americans in 1803 for next to nothing

Lmfao the scariest part is those numbers seem absolutely hittable in a place like louisiana

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

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

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?

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

where's a stolen meme thomas?

i need that dopamine hit

Damn that's hot 🥵 🌎 

The hottest I've been in Was 136 degrees...  I can't imagine 180!

That was miserable because of all the military gear worn as well...

Extreme heat events like this are alarming and highlight the urgency of addressing climate change. Stay informed and stay safe.

I am not so sure to believe those data anymore.
What I see on my weather app is too much off from my sensors readings.
10% or more on temperature. Sometimes the ground wind blows from totaly the opposite direction they have it.
Humidity is oftentimes correct.
4 diff weather stations all from different manufacturers and data more or less the same an all of them. Sometimes because of microclima they show different data but you can feel it going for a walk or cycling.
