I fear that this is the year "wet-bulb temperature" becomes a term regular households across the world become deeply familiar with. It may be as ubiquitous as the term "social distancing" became. I've always naively thought that climate disaster was still 10-20 years out, but it seems like it's going to begin in earnest now and instead be completely catastrophic after these next 10 years. What can I as an individual…

There's literally nothing a "bottom-up" approach will do to effectuate any serious change on the climate. The climate is a dynamic system, and "climate change" is a tautology. At which point, ever, is any "climate" in a static state?

Never, because systems are dynamic, and it's chaotic. Now, if anyone (the State powers and corporate interests) actually WANT to "solve" this "problem," it's, uh, very very clear where to start. Nuclear.

But like many other scissor issues, it will continue to be used as a lever to slice apart groups so's they can fight each other.

When was the last time you asked yourself "What made and or makes me confident in my belief that this is actually a crisis? Why?"

Which papers and statistical analyses have you written? Are you "trusting the science?" Are you versed enough to truly understand how we'd even be able to measure this? Or is it just esoteric enough that it can be used as an engine of disruption, corruption, etc...

At a certain wet bulb temp humans cannot cool themselves off - they die without access to some other means to get cool (like cold water, air conditioning, etc).

Do we have any real world examples of this happening? That would help understanding.

As far as global warming goes, study results indicate that limiting global warming to 1.5 °C would prevent most of the tropics from reaching the wet-bulb temperature of the human physiological limit of 35 °C. https://www.nature.com/articles/s41561-021-00695-3

How is this on the front page? It's as poorly rooted in science as anti-global warming articles. This level of alarmism is dangerous because thoughts of others imprison us if we’re not thinking for ourselves... why would a young person care about the climate if it's already too late.

What we have already done is enough to keep the momentum of global warming going the next centuries. That's a very difficult political reality, it is a great challenge. How can we deal with politics and everything else when the facts look like this?

When the best we can do is to "not make it worse", then it's very hard for people to see the benefits of the changes we have to make.

To add to this with an article I just found “The [wet-bulb] temperature reading you get will actually change depending on how humid it is,” says Kristina Dahl, a climate scientist at the Union of Concerned Scientists. “That’s the real purpose, to measure how well we’ll be able to cool ourselves by sweating.” Source: https://www.theguardian.com/science/2022/jul/31/why-you-need...

Yes, wet bulb temp is in the context of humidity.

Apparently 95f or 35c is the "limit" for humans - where many people will have health issues if they can't cool off otherwise.

We've got 40 years of data on Antarctic sea ice, and over the last 4 decades it's been growing, not retreating. [1] [1] https://nsidc.org/data/seaice_index

That's an accurate but misleading characterization of the data. Anyone can go eyeball the chart you linked and then read this for context to form a more complete opinion: https://www.climate.gov/news-features/understanding-climate/...

How is it misleading when they're talking about "exposing more open ocean to incoming solar radiation and heating" specifically? How is it misleading at all when I've literally just quoted data from a really good site?

Climate change is just one of the things that will get us if we don't find a way to live in our environment. We can't just fuck every other issue to solve that one problem, and hope everything will be fine.

You could include the cost of energy in your statement, and then it says nothing.

Perhaps you could be more specific with your citation. Nothing jumped out at me. Is this what you're referring to? https://nsidc.org/data/seaice_index/images/s_plot_hires.png

Yes, that's it. Slope is positive.
