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.

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

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.
