Hawking On Earth's Lifespan 506
Anonymous Coward writes "According to this news (in German)
of the computer magazine c't,
the world famous physicist
Stephen Hawking predicts,
that mankind will not survive on earth for another millenium.
Hawking fears that the atmosphere will become hotter and contain more and more acid like the atmosphere of the planet Venus,
so that men can no longer live on earth.
The only solution would be to colonize the space and find another
planet to live on."

I beleive there's already examples of this. I'm terrible about remembering details, but I seem to remember some body of water had been polluted with chemicals, then legislation was passed to prevent such gross pollution. In reality it was then polluted by some thing else that was introduced intending to help clean up the pollution. Then they figured out to stop trying to fix it themselves and just let the lake (or river or whatever it was) clean itself up. Evidently, someone did a study and found that the species of something (probably very simple like bacteria, algae, etc.) that were left could evolve more quickly than similar somethings taken from anotehr water source that hadn't gone through such truama.
Anyone know what I'm thinking of? A reference would be great. Or is this something that has been done in multiple locations and is commonly known by biologists?

Actually, if you read through that data your original statement doesn't bear out. You said:
An increase in wealth equals a decrease in population growth rate.
Which is quite different from what these graphs demonstrate. Instead, what they suggest is that at a certain point of development, death rates drop off. After a time, societies react to that and birth rates drop off proportionately. Net result: growth rates stabalize in the long run.
The last paper in particular breaks the chart in to 4 stages, and clearly suggests that the transition from stage 1 to stage 2 results in a pretty dramatic growth rate. So, in that case, an increase in wealth equals a huge increase in growth.
A better way to describe this theory is that the transition to modern times destabilizes whatever societal balances exist between birth and death, resulting in a huge rate of growth, which is then inevitably corrected by society.
Oh, and most of the studies are talking about how "developed" a society is as opposed to how wealthy. The last study correlates the two, although only with a grand brush. There is certainly the possibility of becoming developed without becoming wealthy or vice-versa.
When you look at it like that (where Stage 1 & Stage 4 have similar growth rates) you can't be quite so sure where some societies will be in the long run. Some societies had impressive growth rates before the 18th century when this whole process started. Presumably, they will return to this level of growth at some point.

From my recollection of Earths history, the climate has been through some pretty dramatic changes over the ages, and in general the age of the dinosaurs was warmer than it is now, so how come all this doom and gloom?
Remind me again...what happened to the dinosaurs? They're basically all dead due to the extreme climatic changes that they went on. Sure, some minor species managed to survive, but a large portion of the species all died off. It was once estimated that the genetic variety of the species that existed during those times was at least ten times what we know of throughout recorded history, meaning that even if 10% of the species survived back then, 90 times our current genetic variety died. I think this is cause for some doom and gloom.
There is no denying that global warming will have some pretty catastrophic affects, and may cause famine disease hunger flooding etc. but I doubt it will go as far as Mr Hawking suggests.
Last thing that I heard while chatting about global warming with a climatologist was that, if the current trend continues, conditions on this planet will have reached the intolerable within 750-1000 years. Remember, global warming isn't something that is increasing at a fixed rate. Every day, more and more "greenhouse gases" are being released into the atmosphere, meaning this effect is multiplying slowly. There are always organisms which help reduce this kind of insulating effect (mostly plant life), but in general, we're reducing their effectiveness by reducing the forest areas and also increasing the amount of man-made pollutants that are released.
Maybe space colonisation isn't the way to go and maybe we can somehow stop the current trend of pollution without thought and start to repair the damage that's already done....but I seriously doubt it.

As for man living out the millenia, he's dead because of himself. If the planet's death doesn't get us, the mere fact of overpopulation will. We will never colonize another planet, however, because the populace at large doesn't care about space. It's viewed as a "neato" thing until the bill comes in. Nobody wants to pay taxes to fund NASA, and private corporations have too many regulations on them. (Probably for good measure; I don't know.)

If research into our geological history is correct, in the age of the dinosaurs Earth temperatures were actually several degrees higher, with warm swamps even at the middle latitudes and large forests of ferns.
In our recorded history, we're actually living mostly in a period of COLDER temperatures than normal based on our geological history, thanks to several Ice Ages from 65 million years ago to now. What "global warming" may really be is our Earth finally returning to the higher temperatures of 100 million years ago.

6,250,000 people we need to evacuate each year.
times 1,000,000 dollars per emigrant, equals
6.25 trillion dollars per year.
I can't find any good figures for World GDP, but this is somewhere around a fourth of it. Feel the burn. Of course, the proper figure to compare to is not World GDP, but the cost of our best alternative, the "not fucking up the Earth" plan.

Besides, if we all went to Mars we'd just end up terraforming it eventually anyway; we might as well practice terraforming Earth first.

Actually it might be. Given the toxicity and lifespan of some the garbage we've produced on this planet, moving could be considered an option.
However, before that could happen, we'd have to have a much less expensive system of getting goods to orbit; such as the various SSTO projects that made the news a couple years ago.
Unfortunately, there isn't a lot of 'local' real estate that's any good nearby...

Heat is the only problem long term (Score:2)
I am almost certain that eventually most all of our technology will be 'clean' - it will have to be. We will eventually figure out SOME way of economicaly tapping a small fraction of the energy that the sun disgorges into empty space, and have enough free energy to recycle everything ad-infinitum.
The problem then becomes waste heat. That is a more difficult problem. You have to radiate it away. And since we are on the planet's surface about the only place we have to radiate it is into the atmosphere, where most of it will be absorbed. Sure your factories recycle all of their CO2 or methane, but they now produce waste heat which heats the atmosphere anyway.
Not sure if there is a solution to this, other than perhaps 'piping' heat into space somehow, or reducing the solar input into the atmosphere with orbital 'shades'.

So although it does definitely seem to be warmer now than a couple centuries back, it's still nowhere near as hot as a millenium back, and since the human race didn't die off then I have a bit of an issue crediting the Chicken Littles who foretell global catastrophe from a degree or two over the next century.

Indeed.
I think the terminology you use is in itself too optimistic. "Clean up" makes it sound like its just a problem of moving gross quantities of matter from one place to another; just use some energy to reduce entropy here and dump the waste entropy into space.
Th reality is that we live on a tiny, but highly complex organic film on a big, dead rock. We are destroying biological information evolved by this system over millions of years by destroying habitat and species, essentially taking that organic complexity and turning it into waste entropy.
I don't know if we'll turn the planet into venus; you can't easily project something like this because there are complex feedback systems involved. Perhaps there are situations under which positive feedback could force huge changes in climate, but in terms of gradually accumulating anthropogenic factors people will die off in large numbers well before anything remotely as drastic as the venus scenario plays out. I expect that the world in a thousand years will still look a lot more like Earth than Venus, although possibly with a much larger or much smaller human population.
Enviornmentalists who like to think of the problem as the survival of the human race look down on people who see the environmental issue as one of aesthetic; I think the aesthetic folks may be closer to the truth. We're as likely to go extinct any time soon as the cockroach. I like to point out to my environmentalist friends that if "sustainability" is the sole criteria, we have nothing to worry about because "unsustainability" is by definition a short term condition. The real issue is do we want to have the conditions of equillibrium to occur when we have fouled the nest so badly our options are gone, or do we wish to control some of the conditions under which equillibrium is achieved.
Another way of phrasing the question: do you want the Earth to become a maximally exploited combination human feed lot/garbage pit? Or would you like to hand the next generation a world remotely as pleasant as the one we inherited?

Firstly, because he underestimates the ability of green things to grow absolutely anywhere... I'm not sure humanity is capable of wiping out enough of regenerative greenery to cause that kind of environmental disaster.
Second, he underestimates the force of the demographic transition. As this polluting technology makes individual lives easier, the population growth rate declines and stabilizes, reducing the load on the environment. As it is here in Canada, more people die than are born. Thank goodness for immigrants!
While not ruling out several holocausts, in the long term I see humanity stabilizing with the environment in a new ecological balance. This won't happen any time soon, I think we have to wait until industrialization runs its course and we run out of our fossil fuels. Then, we wait for biotechnology to run its course and settle down into something stable. We then will be in symbiosis with our manmade ecology. Once we settle down into a several hundred year groove and all are new technologies become old, we will be in a steady state. But mind you, I see bumps and population "corrections" along the way.
But once we get to that harmonious steady state... Why settle the stars? We could be happy and content here for millions of years.

Three hundred years ago is when the Little Ice Age [vehiclechoice.org] happened. It was unusually cold then, so of course it's warmer now.
"The most recent big cooling started about 12,700 years ago, right in the midst of our last global warming. This cold period, known as the Younger Dryas, is named for the pollen of a tundra flower that turned up in a lake bed in Denmark when it shouldn't have. Things had been warming up, and half the ice sheets covering Europe and Canada had already melted. The return to ice-age temperatures lasted 1,300 years. Then, about 11,400 years ago, things suddenly warmed up again, and the earliest agricultural villages were established in the Middle East. An abrupt cooling got started 8,200 years ago, but it aborted within a century, and the temperature changes since then have been gradual in comparison. Indeed, we've had an unprecedented period of climate stability." [theatlantic.com]
