While interesting, my main concerns are:
Surely scientists whose area of expertise is involved with global warming would have spotted this already. As I've yet to hear such a scientist cast doubt on global warming, I find it difficult to believe.

Just because it's not on the news doesn't mean it's not happening. So many people have been saying "global warming is our fault and we can do something about it," and the idea has so much momentum, that a TV station would have to be out of its mind to let someone on to say the opposite. This doesn't mean that's happening, I'm just bringing about a possible explanation.

Isn't Greenhouse gases including C02 supposed to be an exponential effect, thus it only becomes a concern after a ridiculously high level?

Yep.

Sorry if my concerns have already been answered, I haven't followed this thread all that closely.

Don't worry about it. Sometimes asking the same question a second time brings new people and opinions, and serves to enrich the discussion.

Therefore it would explain why previous spikes of CO2 are no cause for concern?

In which case, it proves why you should worry about global warming, seeing as at the moment man and his creations and actions are the biggest producers of pollution that creates global warming on the globe, and CO2 levels are well above even those previous spikes, AFAIK.

95% of greenhouse gasses are water vapour. 3.6% is carbon dioxide, and of that 3.6% man's pollution is responsible for 3.2%, meaning we are actually only responsible for 0.115% of greenhouse gas. Your statements are true on the surface: only man pollutes, and CO2 is indeed higher now than it has been before; but the impact of that pollution is so trivial as to not be relevant in the greater scheme of things. If we were to cut our pollution entirely the amount of greenhouse gasses produced each year would drop from 100% to 99.885%. Mankind gives itself too much credit for being able to influence the environment.

out of curiosity, how much of the 95% have we influenced indirectly from the pollution?

I don't know. But given that our massive CO2 output only contributes 3.2% of CO2, I suspect not much. Unfortunately I lack the time to dedicate to researching this today, as work is very busy this week.

I think you are quite misleading. It doesn't matter how much of the green house gasses that are CO2. What matters is the effect it is having.

Also: Since the total effect of the green house effect is quite high (around 30 degrees) a rather "small" difference in the atmosphere will have an effect.

Sigh! As I see it quite much of what you say is either misleading or irrelevant.

Like the temperature measurements in the USA, like the output of volcanoes.

That the temperature has been miscalculated in the USA is totally irrelevant as far as we agree that the global temperature is rising fast, and is causing glaciers and arctic ice to melt (and probably the weather to become more instable).

That volcanoes outputs CO2 is probably also irrelevant, since the output from volcanoes ought to be stable over the eons (more or less). The reason for the CO2 level to be higher than ever is very unlikely to be volcanoes.

And I still think you dodge away from some of the most important questions, which is: Do you acnowledge the possability that you might be wrong? And is it worth it to gamble with the earth on you being right?

speaking purely from a logical perspective, he doesn't have to: he's taking the "things are status quo" case, which is the default. it requires evidence to prove things are not status quo. he's merely suggesting the evidence is overinflated or irrelevant.

also, don't forget that he's said numerous times he's all for environmental cleanup and whatnot on it's own merits. he merely disagrees with doing it "because" of global climate change. in a way, he's taking a form of Pascal's wager: if he's right, but also gets the cleanups, he's happy he got the cleanups. if he's wrong, then he's double happy he got the cleanups :).

the obvious counter question, from one who wasn't advocating the cleanups, would be: "do you acknowledge the possibility that you might be wrong? and is it worth it to gamble all our freedoms on every thing we do which might be a threat? is it worth it to bear all the guilt and shame and panic that comes with every Chicken Little screaming the sky is falling?"

what if the cause of preventing global warming, or the next disaster, or the next, requires us to give up everything that makes us human or makes life worth living? at which point is it better to say "it's better to burn out than to fade away"?

(none of this post reflects my own position. a good debater can take any side of any issue. I'm not good, but I can try :) ).

WARNING!!! I ramble alot in this post. If you want the short version, just go to the last paragraph.


Isn't that exactly what happened when the world trade center got dead? We (USAians) were all for the status quo of ignoring all the minor annoyances, the "signs" of dislike and hatred from the extreme Muslims, until a disaster struck, at which time, we reacted to something that shot us in the face. I disagree with how we reacted, but the point is, humans in general are more content to go with the status quo, and ignore the hints and signs, and wait until it's much to late to fix anything.

So if you didn't read that paragraph, and instead just skipped to this one, I guess what I'm saying is, the loss of freedoms are going to occur, assuming the signs people are reading are right. So the question becomes, lose the freedoms, and keep the environment, or just lose the freedoms?

In the case that all this global climate change stuff is just a load a hooey, you can indeed keep the freedoms, but you will certainly lose fresh air, at the very least. We have proof of that, in Beijing, and they are losing their freedoms in an attempt to clean that up.

I guess it's like this. You have proven problems, and unproven problems. You lose freedoms no matter what ends up happening, and all the freedoms are the same. Wouldn't it be better to lose those freedoms in such a way that there isn't even the possibility of unproven problems from occurring, as compared to having them happen and still losing those freedoms? It's all just a logic problem, and I likely solved it wrong, but it makes sense to me.

Ah, a challenge it is then...
It doesn't matter how much of the green house gasses that are CO2. What matters is the effect it is having.
Close. It's a two part equation: how much of the effect is CO2 causing (according to Wikipedia, 12%), and how much of that (the 12%) is man-made (according to Auger, 3.2%). Those numbers say we're responsible for 0.384% of the greenhouse effect through CO2 emissions. Reducing that in an attempt to stop global warming is like turning off a hose that's feeding Niagara Falls in an attempt to minimize the amount of water that goes over.
Also: Since the total effect of the green house effect is quite high (around 30 degrees) a rather "small" difference in the atmosphere will have an effect.
Now you are being misleading. The sum effect of the greenhouse effect is 30 degrees over a period of 18,000 years. That averages to 1/600th of a degree per year. The greenhouse effect is cumulative, meaning there's all those 18,000 years of build-up already in place and having a strong effect. Cutting man-made CO2 isn't going to change that. In fact, I showed in a post on page 2 that assuming man-made CO2 is responsible for 12% of the greenhouse effect (which it's not, we're responsible for 3.2% of 12% which is 0.384%), it is mathematically impossible for us to do anything but delay things for a few years.
Sigh! As I see it quite much of what you say is either misleading or irrelevant.
You said that already.
Like the temperature measurements in the USA, like the output of volcanoes.
You're taking my quotes out of context. What I said about the temperature measurements being off was that it necessarily casts doubts on all temperature readings, because if one organization got it wrong there is the possibility that other organizations also got it wrong, and those readings should be audited for accuracy. I'm advocating throwing money in the direction of climate change, you should be on my side with this one.

I also wasn't saying volcanoes are the main contributor to CO2, which is what your vague reference implies. I listed volcanoes as one of many other contributors of greenhouse gas. See, here's my quote from near the bottom of the first page of this thread:
I said:
Here are some other CO2 sources that are often conveniently ignored:

- Increased animal population
- Deforestation and destruction of plantlife (less CO2 processing power)
- Melting underwater and underground CO2 deposits
- Human overpopulation
- Occasional volcanic eruptions - yes they are infrequent, but each one contributes significantly more greenhouse gas to the atmosphere than we could ever dream of doing ourselves
Now who's being misleading?
That the temperature has been miscalculated in the USA is totally irrelevant as far as we agree that the global temperature is rising fast, and is causing glaciers and arctic ice to melt (and probably the weather to become more instable).
I've never said the temperature isn't going up. I'm only casting the degree to which it is occuring under a shadow of doubt, until the accuracy of the readings are verified. For all we know, everyone's been using an incorrect formula to calculate temperature, and it's going up a tenth as fast as we think. All I'm saying is that I want to know.
That volcanoes outputs CO2 is probably also irrelevant, since the output from volcanoes ought to be stable over the eons (more or less). The reason for the CO2 level to be higher than ever is very unlikely to be volcanoes.
And I never said it was.
And I still think you dodge away from some of the most important questions, which is: Do you acknowledge the possability that you might be wrong? And is it worth it to gamble with the earth on you being right?
I humbly refer you to silver's response, two posts above mine. I couldn't put it any better than he did, and I'm even responsible for one of the +mods on that post.

Once again, my argument which you continue to conveniently ignore is that we should cut our pollution levels, but not because of global warming. Pollution leads to poor air quality, lung diseases, reduced visibility, and all kinds of badness. Pollution sucks, and we should do whatever we can to minimize it. But we should cut it because it sucks, not because we think we can stop the Earth from warming. It started long before we were spewing pollution, and it'll keep going long after we stop.

Yes, I know you want to stop pollution. But: I highly doubt that USA (or a lot of other countrys) will stop pollution if there is no "better" reason than "pollution sucks".

In what way am I being misleading? Those 30 degrees is not the result of 18 000 years of global warming. That is wrong. If that was the case earth would have been totally covered with ice back then (kind of). We have had quite a strong greenhouse effect for a very lonb time.

This doesn't really matter, though (the 1/600th degree per year is in my opinion another irrelevant information). What matters is that it's the green house gasses which causes the green house effect. And if we change the atmospheric gas levels enough that is going to effect the green house effect.

You say that each volcano eruption contributes significantly more greenhouse gasses than we could ever dream of doing ourselves. Firstly: Is this true? It seems very unlikely. Secondly: It's irrelevant. And thirdly: all of the rest of the CO2 sources you list are probably due to human activities. In which case humans DO cause the majority of the rise of atmospheric CO2.

If this is true, and we are concerned about CO2 it seems to me that one of the best thing we can do is to become vegitarians.

* Rainforests and forests are cut down so that animals can be "produced" there.

* Rainforests are cut down in order to grow soy and vegitables to feed all the animals we "produce"

* Animals themselves contribute to the CO2 levels.

That beeing said I don't believe in Augers numbers. Or he might be missleading. 3.2% sounds impossibly low, and if that was the case I think it ought to be quite common knowledge among serious scientists.


AND! If some un-educated, lazy person who doesn't want to believe in the green house effect happens to read your article I think the main impression it will leave is: "Cool! The global temperature rise isn't that important after all, and even if it was it isn't caused by humans. There was just some scientists screwing up." The probable result if this opinion (which actually IS mileading) becomes widespread is that we will not stop to pollute the environment. After all: People have a hard time caring even when they think that the fate of earth is dependant on action.

Meh! I've got to go now (to a work intervieu). I'll read the other replys more carefully later.

That's because most people are lazy, which is an entirely different problem.

You're contradicting yourself. First you say it hasn't been going on that long, then you say it's been going on for a long time. Be consistent please. Further, your own CO2/temperature graph conclusively proves me right. The temperature has been going up almost steadily for almost 20,000 years. In that time, the change has been 30C.
This doesn't really matter, though (the 1/600th degree per year is in my opinion another irrelevant information).
No, it's arguably the most relevant piece. Saying the temperature has gone up 30C is shocking, but when you find out it's taken 18,000 years to do it, and the temperature has only gone up that miniscule amount each year, it put things more in perspective.
What matters is that it's the green house gasses which causes the green house effect. And if we change the atmospheric gas levels enough that is going to effect the green house effect.
There are two problems with this statement. The first is that we can't change it enough to influence anything. The second is that even supposing we could, and we somehow managed to put a stop to global warming, the inevitable outcome is a period of massive global cooling, which would then put us in very serious danger of another ice age coming faster than it normally would. I don't know about you, but I prefer the heat.
You say that each volcano eruption contributes significantly more greenhouse gasses than we could ever dream of doing ourselves. Firstly: Is this true? It seems very unlikely.
USGS report on volcanoes - one eruption = 2,000 tons of Sulphur Dioxide per day
2004 when St. Helens erupted - 250 tons of Sulphur Dioxide a day for months on end
Secondly: It's irrelevant.
You say yes, I say no. Opinion isn't debatable.
And thirdly: all of the rest of the CO2 sources you list are probably due to human activities. In which case humans DO cause the majority of the rise of atmospheric CO2.
But human influence isn't the question here; pollution is. Whether we are responsible for increased livestock or deforestation is what's irrelevant, because it's not being discussed. The only thing people are worried about is CO2 pollution from things like cars and factories.
If this is true, and we are concerned about CO2 it seems to me that one of the best thing we can do is to become vegitarians.

* Rainforests and forests are cut down so that animals can be "produced" there.

* Rainforests are cut down in order to grow soy and vegitables to feed all the animals we "produce"

* Animals themselves contribute to the CO2 levels.
... Everything except the last line is patently incorrect. Rainforests are not cut down so animals can be produced there, they're cut down for lumber. Rainforest destruction is a problem because other types of plantlife can't grow there, therefore it's impossible for them to be cut down to grow soy and vegetables. In fact, if we stop eating animals, they will reproduce and create more animals. That means more CO2 production. If we're only eating plants, that means less CO2 processing power since they're being devoured. That means if we care about CO2 levels the worst thing we can do is become vegetarians.
That beeing said I don't believe in Augers numbers. Or he might be missleading. 3.2% sounds impossibly low, and if that was the case I think it ought to be quite common knowledge among serious scientists.
You, however, are not a serious scientist, and thus have no way of knowing whether this number is common knowledge among scientists and just being kept from us. Neither do I. However, just because you don't believe in it doesn't mean it is any less likely to be correct.
AND! If some un-educated, lazy person who doesn't want to believe in the green house effect happens to read your article I think the main impression it will leave is: "Cool! The global temperature rise isn't that important after all, and even if it was it isn't caused by humans. There was just some scientists screwing up."
You mean my article is going to have the desired effect? What a catastrophe! I never mention scientists screwing up though, just reinterpreting the facts.
The probable result if this opinion (which actually IS mileading) becomes widespread is that we will not stop to pollute the environment. After all: People have a hard time caring even when they think that the fate of earth is dependant on action.
Your statement is self-defeating. If people have a hard time caring anyway, then my article has no effect. If people do care anyway, my article only serves to reinforce that caring because at the bottom I clearly say that we must reduce pollution, just not because of global warming.
Meh! I've got to go now (to a work intervieu). I'll read the other replys more carefully later.
Yes! Please read everyone's replies carefully and think about them critically. It's all I've ever asked.

You don't even try to understand me, do you?

By the way: You seem to have misunderstood the concept of global warming quite severely. The green house effect has NOT raised the global mean temperature by 30 degrees during the last 18 000 years. If that was the case earth would have been a dead planet 18 000 years ago (more or less). The effect of the green house gasses is to raise the global mean temperature by 30 degrees. However the amount of green house gasses in the atmosphere do fluctuate, which leads to temperature fluctuations.

Please take a look at this little graph. You don't have to trust it, but I think it must be very clear, even to you that the mean temperature hasn't changed that much during the last 450 thousand years. It ceratanly haven't gone up by thirty degrees.

This is quite important. You just state something compleatly absurd as if it was a truth.

Also: I am a Master of Science in physics, thank you very much. I do actually have some scientific background.


All in all I think you are wrong in so much of what you say. I could go in and argue about what you quote, and why you misinterpret me, and why you are inconsistant, but I don't know if it would lead to anything good.

It shouldn't take any effort to understand you. Talk more clearly. I am.

Read me, and every page linked from it (don't worry, it's small). 18,000 years ago the Earth was so cold that most of North America and half of Asia was covered in ice. Most of the rest of the planet was covered in extreme desert. Forests were rare. Earth WAS basically a dead planet back then!

Also, first you said "Also: Since the total effect of the green house effect is quite high (around 30 degrees) a rather "small" difference in the atmosphere will have an effect." Now you say it hasn't happened. Please make yourself more clear.
Please take a look at this little graph. You don't have to trust it, but I think it must be very clear, even to you that the mean temperature hasn't changed that much during the last 450 thousand years. It ceratanly haven't gone up by thirty degrees.
Now you're showing me a chart that says it's not even close to warming as quickly now as it was 125,000 years ago. That means the Earth was warming faster back then, before we were even close to having an influence, than it is now, with us spewing CO2 in to the atmosphere. Your evidence contradicts your claims. The graph is also unclear, because everything is squeezed together so much over the last 15,000 years that you can't even hope to see what's going on in that time. Here is a clearer picture of temperature change over the last 18,000 years. The Holocene Maximum is the hottest period in the mankind's history. It's also 4000-7500 years ago, LONG BEFORE WE STARTED POLLUTING.

Now I'm going to do something you have yet to do, though you have more cause than me: I'm going to admit having made an error. Given the graph I just linked to, the temperature has not been rising steadily, but has in fact gone both up and down. The CO2/temperature chart displays what looks like a constant warming trend over the last 18,000 years, but it seems that chart was labeled incorrectly; it says the orange line is temperature, when it should be delta temperature, and it also has no scale. It seems that through the chart not being clear, I misinterpreted what it said. I would be very interested in seeing a chart that shows actual temperature instead of temperature change, though, if anyone has one. Then we could put this to bed once and for all.
This is quite important. You just state something compleatly absurd as if it was a truth.
Are you denying the last ice age happened? Read this page from top to bottom. As I said above, though, I was wrong about the temperature going up steadily over the last 18,000 years.
Also: I am a Master of Science in physics, thank you very much. I do actually have some scientific background.
Maybe, but this isn't a discussion about physics, it's a discussion about climate and ecology. I congratulate you on your achievement, though. Now if only you could spell...
All in all I think you are wrong in so much of what you say. I could go in and argue about what you quote, and why you misinterpret me, and why you are inconsistant, but I don't know if it would lead to anything good.
I would love for you to find places where I've been inconsistent. Show me one place where I've said one thing, and then said the opposite, without saying up-front that I was contradicting myself. I posted on both sides of deforestation and said so, and I just admitted I was incorrect about the temperature going steadily up by 30C over the last 18,000 years. I can't think of anywhere else I've contradicted myself.

Incidentally, I found a source for how much water vapor is contributed by man: 0.001%. That's another page everyone here should read top to bottom and think critically about, if only for the sake of having more information from which to pull.

tch. ad hominem. I'm willing to give him the benefit of the doubt and assume his spelling of Swedish, his native language, is much better than his spelling of English. (no, I'm not saying you "started it" with the ad hominems, just reminding you rise above).

Bah!

Are you serious? When you look at temperature change you just have to keep in mind what the temperature is today. Of course there was an ice age! Acording to the little graph you posted the mean temperature was about four degrees colder back then. Also: Earth as a whole was certanly NOT a dead planet. The oceans were water, for example.


Well... Here's a list of some things you have said that is more or less inconsistant:


We couldn't change the planet's temperature if we tried.





CO2 values are at 0.038% of the atmosphere of the planet. Yes it's more than ever before, but according to Auer humans are only responsible for 3.2% of that. We couldn't affect the global climate if we wanted to.

________________________________________

...it's amazing how the most obvious items are often the most overlooked. I believe you are correct. It could also account in part for the increased surface temperature in places where deforestation is taking place, because the trees aren't there to absorb the heat with their large, well distributed surface area, and instead the heat goes straight to the ground. It also readily satisfies my hypothesis that some other force is contributing to both CO2 and temperature change.

Nicely done.

____________________________

Obviously you say that human activities which leads to deforestation CAN lead to a global temperature change, despite having said that we couldn't change the temperature even if we tried.


Also, there are other ways for trees to fall down than by cause of man. How many forest fires do we put out each year that are caused by lightning? What kind of effect would that have on the number of trees if we didn't put out those fires before they extinguished themselves? And more to the point, who was performing logging operations 140,000, 240,000 and 340,000 years ago? The argument that man is solely responsible for deforestation only holds if it is provable for the previous warming trends as well. Like anything else, it is a combination of factors that is leading to global deforestation. We probably stop more trees from being destroyed than we destroy ourselves, and that doesn't even count the trees we're planting to replace them.

Now you seem to be saying that deforestation is a natural process which humens are preventing. You later admit that deforestation is in fact caused by humans.


The problem isn't the scientists doing the research and presenting their findings, whatever they may be; it's the bureaucrats looking out for funding and only publishing articles that lead to more money. That's why dissenting scientists are so often discredited by the community, such as the ones I pointed out a few posts ago. By extension, only scientists who support the global warming theory would have been picked for that UN report, because the others would have introduced doubt.




quote:
________________________________________
Do you seriously say that you are quite sure that most/all of the people with expert knowledge in the subject doesn't believe in global warming caused by human activities?
________________________________________

I never said anything of the sort

Here it sounds as if you think that the picture presented in Scientific Journals and the UNs report is misleading since it presents only the money generating findings. It is easy to believe that you mean that the picture presented is not representative with what scientists in general believe. You later say that the picture presented by the UN and scientific journals IS in fact representative. You where a bit misleading here, I would say.


Now here's an interesting question: how many people engaged in this thread besides me are thinking critically about the arguments and sources the other side is providing, instead of dismissing them out of hand because "global warming is so obvious it can't be doubted"?



1) I have NEVER said I don't think the world is warming. I have ALWAYS said it has been happening for 18,000 years, and is beyond our control. If you refuse to respond to the arguments I'm actually making, I will no longer give you the dignity of responding to yours.

You talked about people who think that "global warming is so obvious that it can't be doubted", yet you are one of those peoples yourself.


I know that you will not agree with me, but yes, I do find all of this either inconsistant or misleading. Of course that is just parts of what I think about what you write.

As you so cleverly noted I can't spell. I can't articulate myself very well either. English is not my native language. I'm sorry that I'm Swedish. It must be hard for you to discuss something with someone who can't spell!

Actually I wasn't aware you were Swedish. In that light, I know you are doing the best you can, and will not take note of future spelling errors.

In the interest of having a short post for once, I'll respond by number:

1) I never mentioned human activity there. Even if I did, as I said before, the discussion about the human influence of global warming is specifically about pollution.

2) I admitted up front that I'd argued both sides of deforestation. This one doesn't count because it doesn't meet the criteria.

3) First I said there may be other viewpoints we're not hearing. Then I said I don't believe that the majority of scientists are against global warming by human cause. The two statements are unrelated.

4) As you pointed out, that was me being unclear in my writing. I incorrectly shortened "global warming through man's influence" to "global warming". The error was admitted and corrected.

Okay... Time for a serious answring of your latest posts.

That's because most people are lazy, which is an entirely different problem.
Yep. Lazynes is a problem, but it's related to this. As long as people thinks that it's very important to stop pollution they might accept "uncomfortable" changes of their lifestyle in order to stop pollutions. The fear of human caused global warming might be the motivation we need. Also there actually is a risk that humans are affecting the planets temperature with their pollutions. I think that risk is pretty high. The point is, however that youy work against yourself when you write things which will make people less keen on stopping pollution.


quote:
________________________________________
In what way am I being misleading? Those 30 degrees is not the result of 18 000 years of global warming. That is wrong. If that was the case earth would have been totally covered with ice back then (kind of). We have had quite a strong greenhouse effect for a very lonb time.
________________________________________

You're contradicting yourself. First you say it hasn't been going on that long, then you say it's been going on for a long time. Be consistent please. Further, your own CO2/temperature graph conclusively proves me right. The temperature has been going up almost steadily for almost 20,000 years. In that time, the change has been 30C.

As you know by now you were totally wrong here. The only thing you actually proved is that you can't read these two graphs correctly. I never said that the greenhouse effect hasn't been measurable for a long, long time (hundreds of thousands of years). BUT this last century we have had a rapid increase in temperature which is too odd to be likely to be natural (look at where 2004 is in the graph). That is in my opinion a human influence on the climate, starting with the industrial age.


quote:
________________________________________
This doesn't really matter, though (the 1/600th degree per year is in my opinion another irrelevant information).
________________________________________

No, it's arguably the most relevant piece. Saying the temperature has gone up 30C is shocking, but when you find out it's taken 18,000 years to do it, and the temperature has only gone up that miniscule amount each year, it put things more in perspective.

Again you are wrong in what you say about 30 degrees. BUT even if you were right about that you would still be thinking... odd. If you have something which is slowly, slowly going up as a result of a certain substance over 18 000 years, and you then add a whole lot more of that substance in an instant you would obviously see a very rapid increase in that which is dependent of the substance. That is what has been happening according to the theory of man influenced global warming.

Now, then. If you have something which depends on a certain substence, which is constant during 18 000 years, and you add a whole lot more of the substance in an instant the result will be the same. A very rapid increase in that which is dependent of the substance.

Thus I find what you said odd and irrelevant. During the latest century the temperature has certanly gone up by a lot more than 1/600th degre per year (which is a nonsense figure, since it's based on an asumption that is wrong, but it's the figure you used).


quote:
________________________________________
What matters is that it's the green house gasses which causes the green house effect. And if we change the atmospheric gas levels enough that is going to effect the green house effect.
________________________________________

There are two problems with this statement. The first is that we can't change it enough to influence anything. The second is that even supposing we could, and we somehow managed to put a stop to global warming, the inevitable outcome is a period of massive global cooling, which would then put us in very serious danger of another ice age coming faster than it normally would. I don't know about you, but I prefer the heat.

This is so much nonsense. The CO2 level have (acording to theory) indeed changed enough during the last century to be able to affect the global temperature, even if we use a linear scale. Yet you say it as if you spoke an absolute truth. It kind of irritates me.

The second part is just odd. It's also an example of "un-clean" argumetntation. You try to link me to a coming ice age.

If we put an end to man influenced raising of the CO2 levels that would by no means lead to a global cooling. If that was the case we wouldn't have a rapid global warming now, but rather a global equilibrium (or a slow global warming, or a slow global cooling). Another ice age will come, eventually, of course. And if we see the signs of one we might want to do something about it. Might, since that might be a very dangerous thing to do.


quote:
________________________________________
You say that each volcano eruption contributes significantly more greenhouse gasses than we could ever dream of doing ourselves. Firstly: Is this true? It seems very unlikely.
________________________________________

USGS report on volcanoes - one eruption = 2,000 tons of Sulphur Dioxide per day
2004 when St. Helens erupted - 250 tons of Sulphur Dioxide a day for months on end

As I thought: It is NOT true. This is from your own source:

"Compared to man-made sources, though, volcanoes' contribution to climate change is minuscule, Gerlach said.

Mount St. Helens produces between 500 and 1,000 tons a day of carbon dioxide, he estimates.

Nothstein, of the state energy office, says the Centralia coal plant puts out about 28,000 tons a day. Statewide, automobiles, industries, and residential and business heating systems emit nearly 10 times that amount."

In other words: What you said about volcanos contributing more greenhouse gasses than man could ever dream of ("- Occasional volcanic eruptions - yes they are infrequent, but each one contributes significantly more greenhouse gas to the atmosphere than we could ever dream of doing ourselves") was plainly false.


quote:
________________________________________
Secondly: It's irrelevant.
________________________________________

You say yes, I say no. Opinion isn't debatable.

Let's debate it then. I say it's irrelevant because volcanos are part of the natural ways CO2 is added to the atmosphere, and those we need. If no CO2 were added to the atmosphere in a equilibrium like way (yes, I know that there are fluctuations, but they tend to be very slow, or at least not so violent.) earth would cool down and become an ice planet. The problems starts when we humans disturb the natural equilibrium.


quote:
________________________________________
And thirdly: all of the rest of the CO2 sources you list are probably due to human activities. In which case humans DO cause the majority of the rise of atmospheric CO2.
________________________________________

But human influence isn't the question here; pollution is. Whether we are responsible for increased livestock or deforestation is what's irrelevant, because it's not being discussed. The only thing people are worried about is CO2 pollution from things like cars and factories.

You, sir are now inconsistant. First you say that we shouldn't care about global warming. Now you say that we shouldn't care about arguments which might force you to care about global warming. If you think that humans actually DO influence the global climate I sugest that you go to your article and give it some major updates where you firmly state that you believe humans are affecting the climate, and what you think should be done about the problem (if you think it's a problem). I think you will find that most who are worried about pollutions are also worried about e.g. deforestation.


quote:
________________________________________
If this is true, and we are concerned about CO2 it seems to me that one of the best thing we can do is to become vegitarians.

* Rainforests and forests are cut down so that animals can be "produced" there.

* Rainforests are cut down in order to grow soy and vegitables to feed all the animals we "produce"

* Animals themselves contribute to the CO2 levels.
________________________________________

... Everything except the last line is patently incorrect. Rainforests are not cut down so animals can be produced there, they're cut down for lumber. Rainforest destruction is a problem because other types of plantlife can't grow there, therefore it's impossible for them to be cut down to grow soy and vegetables. In fact, if we stop eating animals, they will reproduce and create more animals. That means more CO2 production. If we're only eating plants, that means less CO2 processing power since they're being devoured. That means if we care about CO2 levels the worst thing we can do is become vegetarians.

This makes me angry, beacuse once again you take on the role as an expert without knowing anything about the subject. You sound quite ignorant at least.

It's kind of scary that you do this sometimes. The soil of the rainforests are NOT imideatly teleported away once the forest is gone. It will erode away with time due to rains and winds, but for a short time you can actually farm in the soil which will soon be gone.

I'm not making this up!

This is also in agreement whith what I learned in school. And please do your own search on the subjet too, if you want.

And then we come to the interesting part! Where you say that being a vegitarian is bad for the CO2 levels. This is such an outragous lie that it kind of shocks me. Once agian you don't seem to have grasped the idea of equilibrium. Without human influence a lot of animals would be gone in a few decades. The meat production is quite big, you know. And, as if that wasn't enough, we consume a lot of energy to produce our meat. It takes about ten times as much energy to produce meat than what it takes to produce crops. Energy which often comes from fossil fuels. Also: deforestation actually DO seem to happen because of meat production, right?


________________________________________
That beeing said I don't believe in Augers numbers. Or he might be missleading. 3.2% sounds impossibly low, and if that was the case I think it ought to be quite common knowledge among serious scientists.
________________________________________

You, however, are not a serious scientist, and thus have no way of knowing whether this number is common knowledge among scientists and just being kept from us. Neither do I. However, just because you don't believe in it doesn't mean it is any less likely to be correct.

I, however, am at least kind of a scientist, as I've already stated. It is irrelevant, but I don't know why you come up with this half lie. Seems rather pointless. What makes Augers statements less likely to be correct (apart from them being seemingly absurd) is that most of the serious scientists don't believe what he believes.


________________________________________
AND! If some un-educated, lazy person who doesn't want to believe in the green house effect happens to read your article I think the main impression it will leave is: "Cool! The global temperature rise isn't that important after all, and even if it was it isn't caused by humans. There was just some scientists screwing up."
________________________________________

You mean my article is going to have the desired effect? What a catastrophe! I never mention scientists screwing up though, just reinterpreting the facts.

That's another thing which just doesn't seem very true. You made quite a big deal out of saying that NASA screwed up when they measured the temperature.


quote:
________________________________________
The probable result if this opinion (which actually IS mileading) becomes widespread is that we will not stop to pollute the environment. After all: People have a hard time caring even when they think that the fate of earth is dependant on action.
________________________________________

Your statement is self-defeating. If people have a hard time caring anyway, then my article has no effect. If people do care anyway, my article only serves to reinforce that caring because at the bottom I clearly say that we must reduce pollution, just not because of global warming.

My statement is (IMO) in no way self-defeating. Your article is likely to make people care less about pollutions. If you can't understand that I will be truely amazed.

A lazy person who doesn't want to believe in the greenhouse effect will probably not care very much about you saying "pollution sucks!" He/she will probably just absorb the "fact" that we shouldn't care about global warming and continue polluting.

Meh! I've got to go now (to a work intervieu). I'll read the other replys more carefully later.
________________________________________

Yes! Please read everyone's replies carefully and think about them critically. It's all I've ever asked.

Once again you are inconsistant. On many levels. Firstly you have said that personal attacks aren't cool. And secondly I do think critically about what people writes. You, however, seems to think that you shouldn't have to think at all to understand what I'm saying. Just look at what you say in the next post:

Might I remind everyone that there is as yet absolutely no proof as to the actual existence of Climate Change? And even if it is happening - well, as Sir Patrick Moore states, 'It's the Sun, only the Sun and nothing but the Sun'

Speaking as somebody from England, I think most of it is an elaborate sham to tax us senseless.

This just isn't true. Either you know it, and are a liar, or you don't know it, and are quite ignorant.

Glaciars and the arctic ice HAS been melting a lot lately. They are NOT doing it just for fun. That is what I call a very vissible proof for a climate change. Apart from that we can actually meassure temperature, and the global mean temperature has been going up quite rapidly during the last century.

Ah. You have conveniently forgotten the second part of my post - the bit about the Sun? There may be proof of Global Warming (although the three science magazines I regularly read have printed no such information) - however, there is no proof whatsoever that it is caused by humans or that there is anything we can to to stop it (seeing as we don't have infinite power over the universe).

I do not think anybody denies that it is the greenhouse effect which makes this planet livable. Without it the equilibrium equations of radiation would dictate that the global temperature on earth would be too low for life as we know it. It is also without doubt that human activities have been adding to the greenhouse gasses. Thus what you say about "the sun and nothing but the sun" is also false.

Please! If you are going to say something try to not say thing that are false as if you were certain they where true.

But really! This has already been said!

DiMono and hartleyhair . . . are you guys basically saying that global warming does exist, but we contribute so little that we can't stop it?

Unless you have any proof that it is a cumulative effect, I don't buy it.
