back on topic:

i think that is why we are trying to make more electric cars so we can to deplete the carbon dioxide.


Dont fool yourself. Companies will never ever ever ever do anything to help the environment, or the planet, or you, or people as a whole.
The one and only thing companies do is make money.
Once in a blue moon we get lucky and a company making money happens to coincide with being environmentally friendly. Its becoming obvious that the worlds oil supply will not last forever, and thats why were seeing more electric cars.
Its difficult to sell a car that runs on gas when there is no gas left, or when it costs an arm and a leg.

Its a cynical way to look at the world, but if your looking at the world any other way, then your a fool.

Humans are relatively ignorant - there are many processes that go on around us that we may not be aware of which contribute a little or greatly to events around us. Even scientists will admit that they don't "know everything".

But we should act on what we do know. Does this "there's too many unknowns" distraction that always gets brought up in the context of climate change still manage to con people? It's just as easy to speculate that humans are making the situation much more dire than the curent model predicts as it is to speculate that we are less responsible for climate change than the evidence suggests. Yet somehow, the folks that bring this up always use the incompleteness of our knowledge to speculate solely from the latter position, all the while presenting a false air of objective skepticism.

We do have a sound scientific model. Incomplete, yes, but what goes into the model is sound science. The tactic of constantly ignoring the model in favor of speculating on a specific subset of the possibilities deriving from the incompleteness of the model gives us a pretty good idea of who is interested in informed scientific discussion and who is interested in shilling for the status quo.
Carbon dioxide variation in the past from wikipedia points to this summary. Basically concentrations are now higher than in the past 20 million years, and before that they were much higher (around ten times higher), for hundreds of millions of years (including dinosaur age).

The wiki article needs updating in light of these new ice cores.

...
The longest ice core record comes from Vostok, Antarctica, where ice has been sampled to a depth of 3,600 meters, corresponding to an age of 420,000 years before the present. [4]

You people are all ignoring the obvious. Since the Earth was created 6000 years ago, these core samples are faked. Therefore, there is no global warming. Besides, the Rapture is coming in a few years anyway.

Sorry, I am a bit late in posting this but: The world is supposed to heat up before the rapture, and fourty years isn't a few. Unless... What is your thoughts on the end of the world? (PM me please, not to get off topic, it may take me a day or two to respond)

The core samples arn't 'faked' there are two obvious reasons we, as believers, can use:

A: The tests are inacurate.

B: When god created adam he didn't creat a baby, he created a grown man, likewise he created a grown earth. (My belief)

C: Scientists are all part of some conspiracy to defraud the bible.[grin] (Joking by the way; in case you couldn't tell)

Out of curoisity, why does everyone post wikipedia like it is facts? Anyone can go on and write articles, sure the stuff is watched but the moderaters don't bother researching everything. Not that I disagree, I fully acept the fact that humans are the cause of global warming and believe that it is true, but I am just saying wikipedia isn't proof. (That borderlines on internet blasphemy doesn't it?[smile])
SotL, didn't you see the bits about tongue-in-cheek, further down? My thoughts about the end of the world are that the Rapture freaks have as much going for them as the Nostradamus freaks, the Mayan-calendar freaks, and the gree-goo freaks.

No, it's not blasphemous. Even the guy that created it admits it's not 100%. People drop wiki links because they are accurate enough for debate. I mean, when you've got people pushing young earth mythology a few factual mistakes are nothing... [smile]

Ahh, didn't see the other part, my bad. 'Gree-goo freaks'(?) Anyhow, there is scientifical reasons why I believe the world will end before 2048, as well as spiritaul. Skipping over the biblical stuff, cause no one would bother with it, the world is steadily increasing its population, true or false? The world is steadily running out of food sources, true or false? I have no proof, but I heard that before and it seemed true to me, and some scientists did a small study on it and decied that, barring natural diasastors wars and famines/droughts, we will run out of food before 2035 or around there. Oh, well. No body cares about that I will venture to guess.

(I was joking about the blashpemy thing) Yeah that's true, a few mistakes don't mean much, but I just thing its funny that people put up a wikipedia article and it is all 'end of discussion' when the poster who put up that link could have made the article minutes before posting(at least, I think they could've, is there a screen were moderaters check it before it gets added or do they just check it after?).

Terrifically false. The problem is actually in distribution. America consumes WAY more than any other nation, and could probably feed the whole world if we'd spend our efforts more wisely.

As far as the world ending soon, it doesn't have to. That's why everybody's making such a big deal out of preventable greenhouse gasses. There are non-preventable sources of climate change, but that doesn't lessen our contributions to it.

@SotL:
I don't mean this insultingly, but have you heard of the Church of Last Thursday? It's pretty heavily slanted satire, but I'm sure you get the gist of it. What do you think it means for people who believe in the possibility of things being created "fully-formed"?

CO2 levels are higher than ever since a long time, im quite convinced of it, and i have little doubt its not because of human activity. even if i wasnt so sure as i am now, erring on the side of caution would have me assume we are to blame. frankly, this new icecore sample doesnt bring anything new to the table, only once again confirms my observation that there are a lot of people who make up their minds before looking at the facts: as pointed out in this thread: correlation != causuality, claiming such will only make you look like an idiot.

however, an interesting question is: what does our contribution to CO2 levels consist of? burning organic carbonhydrates. its no surprise CO2 levels have been much higher in the past. a lot of it has gotten stuck underground over time. even if we do burn all accessible oil and coal, that still only a fraction of what has gotten trapped over the eons.

this planet wasnt sterile back then: it doesnt seem likely well manage to make it so. as a species, im sure well survive.

unfortunatly its only a select few people that stand to lose greatly from any climate change (like my entire country disappearing), while most people have more important things to worry about than a few extra degrees and a decrease of biodiversity on the short term, but would rather make sure they have something to eat. i cant blame them for giving the finger to any oil-slick wealthy western hippy bastards coming to tell them they cant use fossile fuels.

the only realistic solution seems developing something more envirnomentally friendly and cheaper than oil. im all for it.
