You're link just gives me a blank page. But if Yellowstone super volcano did erupt, one wouldn't have to worry about Climate Change or over population anymore.

Humanity, those that are left, would be thrown back into the stone age. With all the debris and ash cloud thrown up in the atmosphere temperatures would plunge, no sun to grow food, what a mess for the survivors. There certainly wouldn't be many. Yellowstone has erupted three times in the past, approximately 650,000 years apart. we're due.


It's high past time that we start electing Americans to congress and the presidency who put America first instead of their political party. For way too long we have been electing Republicans and Democrats who happen to be Americans instead of Americans who happen to be Republicans and Democrats.

Better stock up on canned food. It's going to be a very long winter. Of course, if you had a windmill to run the lights in your well-insulated underground greenhouse, you could grow enough food to last a very long time. The SciFi book 7 Eves had a related plot:

======= SPOILER ALERT =========


A very high speed object hits the moon and breaks into fragments. Those fragments collide a lot and start bombarding Earth with enough meteor strikes to superheat the atmosphere and make the surface unsurvivable. Barely enough people make it to the Space Station to survive and go on to build an orbital culture. When they finally (1000+ years later) make it back to the surface, they find human groups that survived deep underground, and another group who used advanced biotech to become cetaceans. The title comes from the seven women who were ancestors of all the space-based culture.

I have often wondered what ever happened to all the bomb shelters that have been created over the years. There was, if I remember correctly, an entire community created in Montana under a mountain and others too. Some were quite fancy. Every now and then they are mentioned in passing but not often.

I had a friend who was one of the first into Tokyo after we bombed the hell out of them. Thousands dead as the fires created sucked up all the oxygen. He was also one of the first to enter hiroshima and had some pretty interesting pictures of that too. My point is that in a really serious catastrophe shelters are unlikely to help. That, it seems to me, comes under the heading of "Sh*t happens!" and sometimes nothing helps.

Most bomb shelters are good for a few hours while the bombs are falling. Fallout shelters were stocked for a few weeks. For nuclear winter or super-volcano, it needs to keep you in food, water, temperature, and air for a couple of years. Much harder, because you need a power source. And solar panels on the surface won't work.

A nice, small, SMR, could do the power job with no problem, no waste, and be completely safe in its own indestructible vault.

Two cities have backed out of plans to employ small modular reactors this year...dunno why, just saw a headline someplace...the good news is they may have a workable design for a fusion reactor.

I'd sure like to see that in my lifetime. That would be fantastic. Imagine that: All the free electricity you want. Except you do have to pay for all the electrical infrastructure and people to maintain it. But at least we can stop putting carbon into the atmosphere and actually start removing some. If we need to dump excess waste heat, we could just aim simple thermal panels at the clear night sky in the desert. People have been using that method to make ice for thousands of years.

I just had an interesting thought: Summer in Egypt usually has months of temps around 100 F. But the ground temperature down a few meters is 65 - 68 F. What if the pyramids were not so much tombs, but actually summer homes with natural AC for the kings and queens of Ancient Egypt. Humans had been retreating into caves for all of their existence when conditions outside got too nasty. Egypt along the Nile didn't have many natural caves, so they constructed them!

When they died, of course they would be entombed at their favorite summer home.
