The main problem is Volcanic ash and it's not like the ash you find on the barbecue: it is made of tiny pieces of rock. If it falls on your roof, your house can collapse under it's weight. If it gets into contact with cars or airplanes, they will break down or crash. Even worse, if you inhale it, the ash will mix with the liquids in your lungs and form a cement-like substance. You'll literally drown in conrete!

 There are sulphurous gases that turn all rainfall into a blistering downpour of pure sulphuric acid for years to come. There are all kinds of chlorine-bearing compounds, that break down enough of the ozone layer to turn the Sun into a real killer. There's carbon dioxide, the greenhouse gas that not only nibbles at the ozone layer, but also causes long-term global warming. And last but not least, there's soot. A super eruption will darken the Sun, and gradually push the Earth into a nuclear winter for many years, or even centuries, we will have to survive in darkness and cold and no cable TV.

The Yellowstone National Park super volcano has erupted about three times in the last couple of million years. Depending on the wind direction and the size of the eruption, it covered a large part of the West, and can even reach into Canada. A big eruption would not spare Ottawa or Montreal.

So much for Canadian congenital smugness. We're not out of danger in Southern Ontario, or possibly the industrial corridor of Quebec even. Two thirds of the population of Canada is down-wind from the super-volcano, so to speak.

I'm afraid that if a big eruption happened, New England and the Atlantic provinces of Canada might have to ask the Mother Country if we could move back in with the Commonwealth for a while, pending an opportunity to get our house in order. Enough of the West Coast would probably survive to prevent the Mexicans from claiming the whole South West and maybe there'd be survivors in the South and Florida, God help us all if you have to restock the United States with those schmucks.

I mean really, they weren't God's first choice as His Chosen People, which is why he keeps pounding them with hurricanes, tornadoes and other natural disasters, although the message never seems to get through.

doczoidberg: That would be awesome.

 It's time to reduce the planet's population by...oh...about 3 billion.


I think we're quite capable of doing that without any help from Mother Nature, thank you for offering.

Many countries are facing a demographic population bust from aging populations (a billion there), there's massive risk of political and economic collapse in other countries (a billion) and then there's climate change and sea-level rise--Bangladesh is basically a giant river delta that's barely above water at the best of times (a billion people could lose their lives due to flooding, starvation or migration).

Stay the course à la George "Peanut Butter Sandwich" Bush and population will peak at 9 or 10 billion, then drop by half over the next century or two.

We could also face a food crisis bigger than the one feared in the 1970s.

The people who mock at environmentalists and other "alarmists" aren't out of the Malthusian woods yet. Malthus never named a date. He's not tied down to any particular resource peak or collapse. All of the quibbles are based on a misunderstanding of Malthus' point or begging the question. Sure, we haven't hit the wall--yet--but he never said WHEN we would hit the wall. He never said which resource would run out and leave us fighting over what's left of a declining pile. He never anticipated rapid technological growth but then again, can you eat computer chips? No. And making them uses increasing amounts of scarce fresh water, reducing the amount of food you CAN eat.

We don't need no stinking volcanoes. We are our own nemesis. Of course, the volcanoes, asteroids, solar flares, and so forth are real threats and they'll get us eventually, but not necessarily in the next few centuries--some of them are long shots, not immediate and present dangers.

Personally, I suspect that the carrying capacity of the Earth in the long run is about 3 billion--which is about what the population was when I was born. At that level of population we were not depleting the oceans fish stocks or destroying the world's rain forests yet. With technology, a lot of environmental work rebuilding damaged ecosystems, birth control, a balanced population, neither too old nor too young, and wisdom and luck, we could sustain such a population provided we start working at it yesterday.

We need a lot of maintenance and repairs to reach that long-term sustainability, however.

Lots of luck, humanity, you stupid slut!

eyeq360: Not worried.  There are other supervolcanoes to worry about right now.  Another one a 100 million years from now...pshaw.
If someone had conclusive evidence that there will be no more bacon for anyone, permanently, like tomorrow, that's something to panic over.



One example is the Yellowstone super volcano, which has blown its top three times in the past 2 million years.
Thorne published all this in the journal, Earth and Planetary Science Letters. He's rather calm about it, and says it is a slow process from blob to blowout - maybe 100 million years or so.


So once every 600,000 years?
So WHY would he pull 100My out of his arse?

My paleontology professor once professed to not know much at all about human history he had not personally lived through. When someone mocked him for not getting a reference to Caesar, he said "Look that happened 2000 years ago. I'm an invertebrate paleontologist: I don't do  current events."

Okay, that's... plenty of time to get ready. Thanks for the heads up, subby.


Great use of the scary tag too. Subby must pee his pants if someone walks behind him, or says hi.
