As I understood it, the dashed line is just the 35°C wet bulb temperature line.

I think it’s the “old assumed border of survivability” and don’t know if it is based solely on mathematics or on other experiments as well.

I also don’t know on how many individuals the new line is based and what age group the older people one is.

The article is about an experiment, where people are exposed to 35°C wet bulb temperatures, but in different settings. Sometimes lower temperatures but higher humidity, sometimes vise versa, but always 35°C wet bulb temperature.

So far the assumption was, that humans can’t survive a 35°C wet bulb temperature for longer than 6 hours. And at current warming this is unlikely to be naturally the case within this century.

However the experiment gives hints to believe that humans can’t survive at lower wet bulb temperatures either. It looks like with lower temperatures and higher humidity, humans can get very close to that 35°C wet bulb temperature, however people seem to struggle more with higher temperatures and lower humidity.

A possible explanation could be, that while more sweat evaporates in lower humidity, the body has a limit for how much sweat it can produce. And if you keep raising the temperature, that the human body simply can’t produce enough sweat to cool itself.

That’s pretty much what I took away from the article. They mentioned they experiment with several people, however the article was mainly about on person in the experiment, a 30ish year old, athletic male.

Edit: add some graphs from the article. Sorry for low quality, but as you said, the layout is quite atrocious and on my phone it keeps jumping around on it’s own, so I lost patience.

Unfortunately my hardware is too old to play games that are like that.

But I’ve noticed the same with mobile games. My policy is: if that single player game doesn’t start without internet access it gets deleted.

Ironically education is a good way for people not to radicalize, I believe.

It propably grabbed the info off some random number-confusing dude like me, who recently posted the Earth’s diameter would be about 6 km instead of 6000.

Edit: oops, did it again. Meant radius, not diameter…

Eau de Paris’ data shows that pollution levels in the river exceeded regulatory standards on most days between July 26, the start date of the Olympics, and Wednesday. Eau de Paris did not release data for Thursday and Friday, when the men’s and women’s 10 kilometer swims were held.

Lol, do they try the Covid strategy of “no numbers, no problem!”?

“world news”

I also thought about wet bulb and checked the humidity in Delhi, which seems to be just 7 % or so. According to wet bulb calculators that’s still good, like around 23 °C wet bulb.

Interestingly the wet bulb temperature calculators that I tried only work until 50 °C, so that was what I put in.

At 50 °C you need about 35 % humidity to get to 35 °C wet bulb.

Regarding your second point: If I’m not mistaken, the hottest month in the region is around May. The temperature is influenced by monsoons, and although the sun peaks higher in summer, it is generally also more cloudy and rain cools of the surface. That’s why usually temperatures peak just before rain season.

Thank you!

Do you have a link to source of that? I’m pretty sure there are many sensors measuring the temperatures in a city that size.

It is far from over.

We are currently doing the easy part of dropping emmissions. We have not yet peaked, globally speaking. Then we need to get to zero.

The only possible pathway now is overshoot and return. Which means we depend on carbon removal in a big style, in whatever form that will be.

It also means we will go temporarily over 2 °C. That is a critical number where several tipping points could be reached.

Pretty much the hardship has just begun. Now we need to stop emitting completely, somehow in the same time start to remove atmospheric CO² and hope that while we will be over 2 °C that no crucial tipping points will be reached.

Good read!

It did not mention the nuclear bombs that have been lost somewhere.

Very interesting and ambitious mission.

I just read a little about it. Going to the far side is by far more complicated as going to the side that faces Earth. As communication will be lost as soon as the rocket is behind the moon.

In order to keep contact, there are 2 lunar satellites launched acting as a bridge.

The far side is believed to have a very different composition compared to the near side and part of this mission is to find out why.

Any thoughts, ideas?

I thought maybe the far side receives much more impacts as it’s not protected by Earth, so maybe has much more “imported” materials from different areas of space while the near side is still much more Earth like. But that would probably just be surface, I don’t know.

I think not yet. Where I live we had a few cases last year. As I understood the virus jumps rarely to humans for example by unclean cooking habits but doesn’t jump from human to human yet.

I hope I just had bad experience, but I have the aqua with backlight. About 2 years in, the display got terrible; hardly any contrast, especially in the edges. About 3 years in, the rubber buttons just crumbled away; so no more waterproof.

Can’t read anyways anymore, the contrast by now is like egg white on snow white. Didn’t mistreat, it was always stored dry and in no direct sunlight.

I was thinking:

“Hey boss, got the mine setup, should I do camouflage?”

“Nah, we’re low on explosives and tools. Throw on some tin roofs and let the government help us blast mine”

The exercise […] will include Cambodian, Lao, Malaysian, Thai and Vietnamese forces.

These women are incredibly courageous!

Last year I thought these people stand no chance against the governmental oppression and that the protests will fade.

But it appears I underestimated how strong and brave Persian women fight back!

This news story warms my heart.

I’m not denying the science, it is mathematically possible and I actually love the science behind it and reading about it.

I just say we are not yet near fusion power, I think. ITER will start experiments probably this decade. After that they plan to build DEMO, a follow up project which will deliver a little power.

Keep in mind that these reactors are very difficult to built, still. It takes decades to build even without delays.

Fusion is a beautiful source of energy, but it’ll still take time. I don’t think for example that fusion will play a major role in the transition away from fossil fuels as that needs to happen much faster.

Mathematically net positive. As calculating the fusion’s released energy versus what was needed to get it there. As far as I know there is no technology yet on how to utilize and extract that energy. So zero kWh produced for now.

Then you still have loss in the generators or turbines. And then it needs to be able to run 24/7 instead of split seconds, which brings the problem of how to add fuel constantly and how to remove the fusion’s results.

It might be possible but I doubt we are somewhat near.
