Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
The "first time"? Maybe in a controlled environment, but certainly not the first time. People already die from heat exhaustion around the world.
Also, the deadly factor really seems to be time rather than heat and humidity. Saunas are 65-90c with very high humidity and those are generally fine as long as you don't stay in too long.
Tell me that you haven't read it without telling me that you haven't read it
Owen has been put into the climate chamber by Jem Cheng, a research fellow at the Heat and Health Research Centre at the University of Sydney.
It’s part of a world-first study all about finding out at what point heat becomes deadly. Fifteen years ago, scientists proposed an environmental threshold at which no person would be able to survive for six hours.
But these conditions have never been tested on humans.
Until now.
“This study is all about human survivability,” Dr Cheng says.
“So we are the first to actually put people in these environments to actually see, physiologically, what is happening to their core temperature or to their heart rate.
What this new model shows is, when you take into account the limitations of human physiology, these upper wet-bulb temperature limits look as though they are much lower under certain types of conditions.”
I did read it. All of those conditions have been experienced by humans, just perhaps not in a lab controlled study.
My problem is the clickbait headline. Its a bad headline.
doesnt change the misleading title. i was in a sauna the first time at age 5 or 6. that can be pretty daedly
Sorry, nonsense
People have been dying from heat in droves since decades ago. I recall 10-20 years ago a heatwave that overflowed morgues in France.
Not saying that climate change isn't real or not disastrous, it is and so much more.
Just that this title is misleading at best
There are examples of exceptional heatwaves like the one you're thinking about. The article is about testing people under controlled conditions to figure out exactly where the point that things go from 'healthy adults will be fine' to 'not just the sick, pregnant, young, and elderly suffer, but huge chunks of the population die'
Since I can never remember what wet bulb is, this video does a good job explaining it:
