Such a sweeping change in temperature is *predicted*, while zero change at a level that is measurable has been detected. Those folks adhere to the precautionary principle, which in essence says "So what if we have no data ..... if our s.w.a.g. comes true it'll be bad!". I, for one, like to have at least some hint of what is predicted before flying off the handle about it. Maybe more in their case because so much of what they have said in the past has been utter bull-fodder manipulated to fit their profile of fact.
Fuel cells are cool and all, but people forget they are much like batteries. It isn't a magic "just add water" source. You have to "charge" it, and where do we get most of that energy? Yup, burning fuel. If we turn to nuclear power as the source it'll be a lot cleaner but good luck getting even a single plant approved. <!--emo&???--><img src='http://www.unknownworlds.com/forums/html/emoticons/confused.gif' border='0' style='vertical-align:middle' alt='confused.gif'><!--endemo-->
Solar, wind, geothermal, and biomass are either too land-intensive, too low output, or too costly at this stage. Gasoline is just that efficient. It would require a huge amount of area for equivalent per gallon energy of canola oil or whatever it is they wanna use. And anyhoos, burning plant based stuff produces much of the same pollution. Solar might be good for individuals, but you can't run a city off it. The demand is just way too high.
I don't think we'll willingly die out if we truly see the end coming. Heck even the most dire predictions for climate would not kill off the human race. Our style of life might totally change either forwards or backwards but I don't see us going anywhere soon. Cosmic catastrophes aside of course.
Dude, there is proof of climate change. Lot's of. -> Intergouvernemental Panel for Climate Change. Of course, the alternatives are not as efficient as burning oil, and it will stay that way if we are not willing to invest in it NOW.

Again, it is not proof of climate change they put out. It is a *model* that is basing itself on something that *hasn't happened*. Recently, even the data they used to generate the output was called into question because the folks who ran the original study manipulated the data.
We've been investing a lot of money into alternate energy, at least the DoD and NASA have. We also have a better source, but no one wants to build more plants that use it. Efficiency has to do with the molecular structure of the source oil. That is not going to change unless we use organic chemistry to develop an artificial gasoline-like substance. But the biomass to develop such an animal would be relatively equivalent to that which developed crude (in other words a lot). What has come out of all that money is a more efficient use of energy, but generated from conventional sources.
The future of energy is in my opinion fission or fusion. With the latter depending on the outcome of quantum experiments to explain mass and gravitation.
So, technically I may have to backtrack and say that when we discover the Higgs Boson we might implode ourselves. <!--emo&:p--><img src='http://www.unknownworlds.com/forums/html/emoticons/tounge.gif' border='0' style='vertical-align:middle' alt='tounge.gif'><!--endemo-->

If a 4-year old boy told you he will live forever, would you take him seriously? Put this into perspective. Human-kind is nothing but a blink in the grand scheme of things. I think you've gotta have balls to say humanity will live forever.
I think it is fun to ponder the possibilities of where humans will be in the long run; I even wonder why God created me in the most boring era of humanity; if I had a choice, I would have wanted to live in a time where interstellar space travel had just started and the world, united as one. Whether the world will end tonight or two million years from now doesn't matter. In my opinion, doing the best we can do and thinking optimistically is what is most important in the survival of our species, besides the occasional military advancement here and there, hehehe.
Anyways, I agree with Hawkeye, the universe has got to end and therefore humanity too. Sure we could send colonies across the galaxy, perhaps obtain alien technologies here and there, but once that universe ----------------><------------------ it is all over...

Negative. The sun will run out of Hydrogen first, it will then inflate into a Red Giant star, where it will remain so for several million years. After that time, it will puff off it's outer layers and shrink into a white dwarf. The earth will be roasted and subsequently eaten by the sun. Mars will just bake if it's lucky.
Even so, Life may continue to go on once Europa freezes back over thanks to Jupiters rending and tearing of it's core. The Galilean satelites constantly tug and pull at one another in such a fasion as to keep the orbits slightly ellipitcal, so it may very well be possible for life on Europa (and Man) to continue underneath it's ice for quite some time.
I believe these are more of a natural phenomenon than anyone will tell you. And even if it does go up 10 degrees worldwide... SO WHAT ? It'll turn all that russian tundra into farmland for a change and they'll get back on their feet.
I hate to say this. A rise of 10 degrees celsius is what caused the Permian extinction. This put the dinosaurs extinction to SHAME. 97% of ALL life on this planet pretty much died.
The same event today would be just as catastrophic, perhaps less so since we can act to reduce the severity of the extinction (seed banks etc). Mammals are also more resistant to temperature changes then reptiles because of being warm blooded. Still, I daresay that 95% of all life would simply die if a rise of 10 degrees on the whole were to be experienced.
Simply not gonna happen. I forget where I saw the article, but I KNOW that some dude figured out a way to turn almost any junk into oils and it's other base components. I remember that the article said that the first full scale plant that will be doing this conversion is planned to open in 2005-2007 to prove that it works on a large scale.
I think your meaning is Coal --> Oil Conversion. The supply of Coal is meant to last for another 200 years at the present rate, so converting coal into oil is considered somewhat economical. The germans used it in WW2 when they couldnt import any oil, though it still didnt win them the war.
See if you read carefully you would know what I meant. I meant that if a large asteroid were to hit the earth, the temperature would go up millions of degrees from a thermo-nuclear explosion, killing us all.
When an asteroid hits the earth, it is the conversion of kinetic energy into heat light and sound. The energy released is measured on a nuclear scale because a nuke converts atomic energy (E=MC^2) into heat light and sound, and because it is the only comparable measure.
The immediate effect of an asteroid is highly localised. At ground zero, the heat WILL be in the millions of degrees. 100 KM away however, you may encounter a hot blast of wind that may knock you down.
The long term effects are FAR more devastating then the immediate impact itself. Dust is thrown up, the suns power to warm things up and light up the day is reduced, plants die, animals die. Eventually things clear up and life starts recovering right away.
It would take a lot of energy to make the earths surface reach "Millions of degrees". Heck, not even the period of intense bombardment after the earth was fairly formed could raise the temprature to that level, the best that bombardment period could do was melt the crust. Not even the Big Whack did it, and that sent the moon going into orbit.
To put it into perspective... NOT EVEN THE SURFACE OF THE SUN IS THAT HOT!
I did a custom investigation into impact. I directed a large asteroid into the earth at fairly high speed.
Resulting force on earth would have equalled 75 Trillion newtons.
F=MA Therefore A=F/M
M = 5.972 * 10^24 Kg
75 Trillion / 5.972*10^24 = Small number
This "asteroid" may as well have been a planet. If all it's energy were converted into heat, then it might vaporise a large chunk of the earth resulting in volcanic eruptions that could screw life over but not kill it. If all it's energy had been directed as kinetic energy, the earths orbit would only have shifted out a couple of kilometers (I think I calculated the resultant acceleration to 0.03 m/s if memory serves), meaning slight global cooling.
Fact of the matter is an asteroid is not enough to destroy the earth. You either need
1. A <b>LOT</b> of asteroids, far more then there are currently in the solar system, or 2. Something the size of a planet
Now, unless that asteroid happens to be made out of antimatter or quantum black holes, you got nothing on asteroids destroying earth.

My own personal view; The non-existence of humanity is inevitable. But everyones view on such a question is completely subjective. It all depends on the perspective one takes in the argument. Some try to rationalize it out with facts and reason and past studies, etc. When asked of my perspective i tend to be more of an empyriacist myself. Bahh i'll post again another time, i have an errand to run.
Perhaps the extinction of humans would result from a mellenia of interbreeding with an alien species or something odd like that... there are lots of ways it could happen.
has everyone forgoten about space travel's advances within the next 200 years?
Hmm...you bring up an interesting point Trevelyan. In the next hundred or so years, our advances in space travel may allow us to leave earth and colonize other planets.

What you left out however, is that he also said that if all things in the universe were to disapear, their time and space would disapear too, but time and space would still remain.
Time and space can neither be created nor destroyed. Merely converted and manipulated.

Negative. The sun will run out of Hydrogen first, it will then inflate into a Red Giant star, where it will remain so for several million years. After that time, it will puff off it's outer layers and shrink into a white dwarf. The earth will be roasted and subsequently eaten by the sun. Mars will just bake if it's lucky.
Even so, Life may continue to go on once Europa freezes back over thanks to Jupiters rending and tearing of it's core. The Galilean satelites constantly tug and pull at one another in such a fasion as to keep the orbits slightly ellipitcal, so it may very well be possible for life on Europa (and Man) to continue underneath it's ice for quite some time.

I believe these are more of a natural phenomenon than anyone will tell you. And even if it does go up 10 degrees worldwide... SO WHAT ? It'll turn all that russian tundra into farmland for a change and they'll get back on their feet.

I hate to say this. A rise of 10 degrees celsius is what caused the Permian extinction. This put the dinosaurs extinction to SHAME. 97% of ALL life on this planet pretty much died.
The same event today would be just as catastrophic, perhaps less so since we can act to reduce the severity of the extinction (seed banks etc). Mammals are also more resistant to temperature changes then reptiles because of being warm blooded. Still, I daresay that 95% of all life would simply die if a rise of 10 degrees on the whole were to be experienced.

Simply not gonna happen. I forget where I saw the article, but I KNOW that some dude figured out a way to turn almost any junk into oils and it's other base components. I remember that the article said that the first full scale plant that will be doing this conversion is planned to open in 2005-2007 to prove that it works on a large scale.

I think your meaning is Coal --> Oil Conversion. The supply of Coal is meant to last for another 200 years at the present rate, so converting coal into oil is considered somewhat economical. The germans used it in WW2 when they couldnt import any oil, though it still didnt win them the war.

See if you read carefully you would know what I meant. I meant that if a large asteroid were to hit the earth, the temperature would go up millions of degrees from a thermo-nuclear explosion, killing us all.

No.
When an asteroid hits the earth, it is the conversion of kinetic energy into heat light and sound. The energy released is measured on a nuclear scale because a nuke converts atomic energy (E=MC^2) into heat light and sound, and because it is the only comparable measure.
The immediate effect of an asteroid is highly localised. At ground zero, the heat WILL be in the millions of degrees. 100 KM away however, you may encounter a hot blast of wind that may knock you down.
The long term effects are FAR more devastating then the immediate impact itself. Dust is thrown up, the suns power to warm things up and light up the day is reduced, plants die, animals die. Eventually things clear up and life starts recovering right away.
It would take a lot of energy to make the earths surface reach "Millions of degrees". Heck, not even the period of intense bombardment after the earth was fairly formed could raise the temprature to that level, the best that bombardment period could do was melt the crust. Not even the Big Whack did it, and that sent the moon going into orbit.
To put it into perspective... NOT EVEN THE SURFACE OF THE SUN IS THAT HOT!
I did a custom investigation into impact. I directed a large asteroid into the earth at fairly high speed.
Resulting force on earth would have equalled 75 Trillion newtons.
F=MA
Therefore
A=F/M
M = 5.972 * 10^24 Kg
75 Trillion / 5.972*10^24 = Small number
This "asteroid" may as well have been a planet. If all it's energy were converted into heat, then it might vaporise a large chunk of the earth resulting in volcanic eruptions that could screw life over but not kill it. If all it's energy had been directed as kinetic energy, the earths orbit would only have shifted out a couple of kilometers (I think I calculated the resultant acceleration to 0.03 m/s if memory serves), meaning slight global cooling.
Fact of the matter is an asteroid is not enough to destroy the earth. You either need
1. A <b>LOT</b> of asteroids, far more then there are currently in the solar system, or
2. Something the size of a planet
Now, unless that asteroid happens to be made out of antimatter or quantum black holes, you got nothing on asteroids destroying earth.

Neg, I'll look it up when I get some time. But I remembered seeing specific results of what they got when they threw stuff like computer monitors, chicken guts, and other random stuff into a small scale version of the machine.
I wish I remembered more about it, but I seem to remember that the process was not new (it had been around since the 60's). But the dude had found a way to make it uber efficient to the point of actually being worthwhile.

Not to contradict your argument here Cronos, but well, the center of a blow torch flame is hotter than the surface of the sun actually.
Yeah, but what if it didnt begin, and who says it end?

the center of a blow torch flame is about 1000 degree, the sun is over 1000 million degrees

2,400 degress is a lot less then the 1,800,000 degree corona. The absolute coolest part of the sun lies under the corona, around the chromo/photosphere, at just around 15,000 degrees.

Actually it is 5800 K, which is approximately 5526.85 degrees celcius vs 1300 degrees celcius for the blow torch.
It is only 4.25 times hotter. We're not talking about trillions here.
Not a hundred billion trillion gazillion.. what did you say it was?
