Great discussion of the secondary effects of Climate Change that are rarely discussed. CO2 and warming get the focus of attention but there is a long list of other things that are getting worse.
I recently read an analysis of how toxic the growing wildfires can be. There are so many toxic and carcinogenic chemicals released when your average house burns that the smoke is poisonous.
As you point out, those chemicals settle somewhere. First as dust that can be carried in the wind. Then, as contamination in the rainwater that carries it into streams and rivers. Finally becoming sediment and working its way up the food chain.
Almost all of our synthetic replacements for natural products and fibers are extremely toxic when burned. All of our garbage now has to be buried. Because burning it is just too dangerous.
The drying of the Great Salt Lake is another secondary effect of Global Warming. Again, you are right. It's a freaking disaster on a National Catastrophe level.
Salt Lake City could become untenable within a decade.
No one seems to understand the magnitude of that. The collapse of a major US city. The financial loss of 10's of billions just in real estate for millions of people.
Millions of people displaced and in need of housing.
A whole city's worth of infrastructure rotting away. Needing to be carefully deconstructed but all too likely to burn.
Releasing a massive toxic plume downwind.
This is what Collapse is going to be. The synergistic coming together of all these secondary effects crippling our ability to respond to the accelerating crisis.
The parallels with the collapse of Rome are scary. I am rereading the book on how Climate Change took down Rome. More and more I see it as "A Distant Mirror".
