Well, since you like to cite a random graph from the Petit et al paper, why aren't you citing what is actually written in the paper?

"The extension of the greenhouse-gas record shows that present-day levels of CO2 and CH4 (360 p.p.m.v. and 1,700 p.p.b.v., respectively) are unprecedented during the past 420 kyr. Pre-industrial Holocene levels (280 p.p.m.v. and 650 p.p.b.v., respectively) are found during all interglacials, while values higher than these are found in stages 5.5, 9.3 and 11.3 (this last stage is probably incomplete), with the highest values during stage 9.3 (300 p.p.m.v. and 780 p.p.b.v., respectively)."

For their entire data set, the CO2 levels, and the methane levels are at their highest levels. It isn't just barely higher, rather the current reading of CO2 is 20% higher than the higest value for the past 420,000 years, and the methane level has more than doubled.

Please, that ignores all basic premise of science, where you statistically analyze the data, coming up with a correlation coefficient. From what I have seen, nobody has done this. That could be for two reasons.

1. They have done it and the R2 absolutely sucks and you cannot prove a direct correlation with any high amount of certainty and the info was buried because nobody wants to admit they are full of crap.

2. They won't do it because they know it's a hopeless study, because if somebody did it and released the data, they'd be ridiculed for being Republican shills, they know that the R2 is too low to be conclusive.

Seriously, did you actually take the time to read the Petit et al paper, because right after their discussion of the unprecidented CO2 and methane levels, they said:

"The overall correlation between our CO2 and CH4 records and the Antarctic isotopic temperature5, 9, 16 is remarkable (r2 = 0.71 and 0.73 for CO2 and CH4, respectively). This high correlation indicates that CO2 and CH4 may have contributed to the glacial?interglacial changes over this entire period by amplifying the orbital forcing along with albedo, and possibly other changes15,16. "

So not only are the CO2 and methane levels unprecidented, they have a good correlation between those gases and temperature. This begs the question, why cite their paper in the first place?


Ohhh, the correlation between Co2 and temp increase is certainly high. HOwever, the correlation and the *direct* link between man's release of Co2 and the corresponding increase is not only not measurable, but if it were would be a dubious correlation at best.

I find it amazing how arrogant people are to think they know exactly what the Earth is doing and they think that they have figured out ALL variables in a multi-variable regression and can firmly say that they have determined that randomness is not random, but ordered and directly influenced.

Only those ignorant to statistics would claim anything but random until a proper analysis is carried out.

What science? The one that can't prove conclusively that black holes exist or another form of body makes black holes? Or the one that can conclusively say that x causes y, no matter that y is a random variable that has fluctuated over the past 600-700 thousand years?

GW is a theory. It cannot be replicable on a global scale nor has Man's influence been statistically proven. It just cannot be. Why? Because the current Co2 and temperature peak started tens of thousands of years ago, long before Henry Ford started manufacturing cars on an assembly line. Ohh, but thats right, those acient civilizations that numbered in the tens of thousands worldwide burned so much wood that they caused this current spike.

Lets not forget the dinosaurs farting so much that they caused the last one.

You people are so gullible, you swallow and head in the direction that anybody points you in, forgetting reason, statisitics, and truthful science. You listen to select theories rather than a broad-base. You refuse to acknowledge that the ice caps weren't in existance before nor will they always be there in the global cyclical pattern. You refuse to acknowledge that the ice caps are getting thicker in the middle but smaller along the periphery. You fail to acknowledge that the Sun's ouput has increased over the past 30 years when we finally have had accurate readings. You fail to acknowledge that the Vostok cores show that peaks and valleys existed long before man.

Yet I acknowledge that whatever we are doing, no matter if it has a GW impact or not, is not good and I fully acknowledge that we need to stop. I despise SUVs and the attitude that we shouldn't care at all and I fully advocate all alternative energy sources while diminishing any Co2 or other harmful gas production. As somebody mentioned before, don't crap where you eat.

I just refuse to acknowledge that man's Co2 = GW, because no matter what you say, it is *NOT* scientifically nor statistically proven.

You people are nothing more than robots of Gore, pathetic in your lack of understanding of statistics and blind to the reality that the Earth has been doing this stuff long before we got here.

Global warming as a resault of mans transformation of vegetation and the use of fossile fuel is as close to being proved as it gets. Some people with economic / political interests would have us belive different however.

1) It is a fact that the level of CO2 has increased dramatically during the last 250 years, particulary during the 20th cent.

2) It is a fact that CO2 blocks theremal radiation but is transparant to visible light. Hence it prohibits heat from radiating from the surface of earth and out into space. From a primitive radiation balance calculation it can be shown that the average temp on earth would be -18 C if we had no atmosphere. The transparancy at certain wavelengts (or lack of) of various gases in the atmosphere is responsible for the fact that radiative balance is established at a significantly higher temperature (about 16C). The green house effect IS A FACT. That we would not change the temperature for radiative balance by altering the components of the atmosphere would be against all experiance.

3) It is a fact that the altered levels of CO2 in the atmosphere results from human activity. During a period of a little more than 200 years conentrations of CO2 has increased by >30%. Acording to a previous post those levels havent been seen for 650 000 years. I cant verify this is the exact figure but it is something of that proportion. 650 000 years ago is before the existence of dinosaurs, it is in the beginnings of advanced life with a completely different eco system. That should give some perspective on the scale of this.

4) It is a fact that temperatures have changed dramatically during the last 100 years, in a way never seen before.


So. We have altered the components of the atmosphere. We have very strong reasons to belive that this should result in global warming. During the last 100 years we have seen rising temperatures that has nog equality in history or prehistory.

What conclusion should we make from this? The most resoneble one is that global warming results from human activity, particulary the use of fossile fuel. Is it proved? From a strict scientific point of view it isnt. When scientists say we lack a proof it is mainly out of a acaemic point of view. I have met a lot of scientists working with this matter both at my University and in a private company. They all regard this as a fact. its time we admit what is going on and focus on solving the problem instead...

As for the price of failure, global warming means more masstransport. Areas near the equator will be hoter and dryer while land remote from the equator will be wetter and warmer. This means parts of the world will become uninhabitable. Many countries close to the equator are poor and lack the resoureces necessary to deal with extreme wether. In fact, it is proposed by researchers that missing rain periods in parts of africa may result from this. If that is true, the bodycount is about 2 000 000 allready. Of course this is not a fact but it can give you some perspective on the effect of altering our climate. Also keep in mind that this is only the beginning. In some decades the impact of this will surface. we can expect destroyd ecosystems, eliminated species and millions of human causalties in the third world. The fact that the scientific evidence of global warming was some what incomplete will not be very usefull then.

Apparently you disregarded every non-conforming science opinion that is out there......It is a FACT that CO2 is on the rise. It is a FACT that there has been FAR higher CO2 readings in the 1930's than now. It is a FACT that CO2 readings have in the past been even higher than that. It is a FACT that the earth has been hotter and COOLER than is is at the moment.

Some studies suggest that CO2 is not the sole terror suspect in Global Warming..

Amazing how some people (on AT and in the U.S., in general, if AT is a representative sample) can be against taking measures to prevent - or reverse - not only global warming, but also pollution and waste (although many such measures are simple, efficient and cost-effective), but they will advocate continuing the war in Iraq and what's generally known as the current "war on terror".

Amazing how reading comprehension of such apparently learned people is so low as they cannot see that *NOBODY* here has advocated not stopping current activities. Even more amazing is how dense people are in their polarization of an issue, where somebody like me who believes that man made co2 does not equal GW, is then labled as a polluter or a pro-Iraq war person.

Finally, I find it continually amazing that people are so willing to ignore data on either side of the issue and only result to a "them or us", "left vs right", "pro or anti bush", or some such pigeonholing bullcrap.

Get a damn clue. Just because I refuse to believe that man = GW doesn't mean I don't think we should stop what we are doing. In fact, I have yet to see one person say that pollution is good.

Oh, really?

All I've seen in this thread is "shoot the messenger" knee-jerk reactions. I have yet to see one of you naysayers coming up with a reply like "Al Gore's film is full of crap, but it's making a good point, so here are things that I do, and everybody else should try".

I've seen the same (type of) people, a few years back, crapping all over Kyoto. Granted, it isn't the best deal we could hope for, but it's something to start with... From a strictly neutral standpoint, I find that the lack of care about the environment goes hand in hand with a certain political model of thinking currently prevalent in the U.S.

Mark my words, the Clinton administration will be perceived as a beacon of light in a few years, if the present trend continues.

No, the vast majority of the replies are....

Correlation != causation. Man's limited increase of Co2 emissions compared to the levels natural in the cycle of earth does not mean that we are causing the planet to warm up.

Furthermore, I have yet to see anybody bash Gore to the point of calling his stuff complete baloney. I also have yet to see anybody say that his points as far as reducing pollution are complete baloney.

All I have seen from the GW zombies is "you guys are oil shills" or "you don't care". Please, if you want anybody like me to believe you you can take the following steps.


1. Come up with statistical proof that man's Co2 has definitely increased the temperature. To do this you must eliminate all extraneous variables, such as sun intensity increases, increased CO2 due to natural occurances, while focusing on man's CO2 emissions alone and the temperature increases. I bet your R2 for man's Co2 will be fekkin low.

2. Stop polarizing the issue. Nothing turns me off faster than somebody saying I don't care because I think their point isn't valid. *I DO CARE* as do most people here. I just don't make the link you do. You want to have people change? Stop polarizing them into pro Iraq-war junkies like you just did you polarizing pigeonholing whacko.

I am as anti-bush, anti-iraq, and anti-gas guzzlers as they come (my wife and i have 1 4-banger, she rides the subway after I drop her off). Yet some moron like you has to come along just because I don't believe in one stupid issue and label me as everything else.

In the end, you are no better than the polarizing fools like Rumsfeld, Cheney, or Bush. You are just opposite sides of the same ugly coin.

LegendKiller,

I didn't call you a moron anywhere in my posts. I believe I maintained a civil tone throughout my input. But you obviously miss some civil education, so I'll take my gloves off as well.

You come across as a hysterical individual, clamoring for attention. And your incessant demands for utter and irrefutable proofs of human activity changing the climate, bleeting "correlation does not equal causation", do very little to convince me otherwise.

If you re-read my first post, I'm not even pointing a finger at you, or anyone else in particular. I said "some people here." Now, who's generalizing, Miss Hissy-Fits?

bah...

Sorry, everyone else, for the detour.

In the end, it boils down to this: Whether the climate change is caused primarily by humans or someone else, it is nonetheless true that we have the possibility to stop and prevent further damage to the eco-system, and there's no excuse for not doing so.

Yeah, because well orgnized logic, such as asking for proof of correlation or high R2 is such a hysterical and poorly organized point that not one person has provided anything. Furthermore, your attempt at minimizing my argument by labeling it hysterics is laughable, you have no logical counter to anything I have stated, so your next fall-back point is to undermine my argument by assuming that I am hysterical. Great one sparky, talk about shooting the messenger, you just did what you accuse others of.

I don't care if your pointing the finger at me or not, your obvious backtrack only points out that you don't have any specific evidence of anything at all. Show one person who is obviously pro-pollution and pro-iraq.

What it boils down to is that we have limited impact on our environment. The last peak in Co2 and temperatures was not caused by us and it's pretty silly to say that we caused this one, especially since it began more than 10,000 years ago. You guys are taking 100 years and saying "wow, we have all of this evidence" or 300 years of spotty records and are trying to extrapolate some iron-clad conclusive fact.

If you want to stop a lot of greenhouse gas, kill everything that farts, including the dinosaurs that caused the last Co2 peak. That way you can have your pristine planet, except you'll be dead too.

CO2 levels did start rising about 10-20 thousand years ago, however this was following the normal trend of CO2 variations along with ice age cycles. The CO2 levels did not dramatically rise until the Industrial Revolution.

This is a very interesting claim since your views are at odd with the vast majority of scientists in this world.

This is irrelevant, because the current rate of melting will end up putting a much larger strain on humans than a long-term gradual melting would.

Originally posted by: LegendKiller

Again, this is irrelevant. All that matters is that the ice caps are melting faster than they are growing. At the current rate of warming, the global sea level could rise 20-40 feet within a century. This would displace hundreds of millions of people.

This is true, however, unlike the warming trend, there is no reason to believe it is unusual. Based on a longer record provided by tree rings and sunspots, fluctuations in the sun's output appear to be related to past warming/cooling cyclesl.

Originally posted by: LegendKiller

I believe there is only one Vostok Core, and it provides the exact data that has led scientists to conclude that the current warming trend is out of the ordinary. The current warming trend is not consistent with the temperature cycles over the past 400,000 years.

Originally posted by: LegendKiller

Scientifically the evidence is extremely strong. The current warming trend coincides with the current skyrocketing of CO2 levels AND with the Industrial Revolution. Graphs of the data are easy to find and the correlation between them is clear. The chance that this is all happening by coincidence (as you claim) is so small, that no rational human with knowledge of all the facts would consider it.

The sad thing about this claim is that even a thirty second glance at the data shows that the current warming trend is not consistent with any past climate activity on earth.

Are we arguing over measured and calculable facts that support Mans' impact on global warming? CO2 release by human activities is a measurable quantity. CO2 is a green house gas. Venus is an example of a run-away process, Mars is an example on the lack of one.

As for the sun's fingers: http://www.cnn.com/2006/TECH/science/09/15/global.warming.sun.reut/index.html

What other 'natural' causes of the present warming are still alive and kicking?

Of course, LegendKiller will typically note the last sentence. It doesn't really mattery what is growing increasingly likely to environmental scientists across the globe, it doesn't really matter that >50million years ago, when the levels of co2 were likely much higher than today- there were no humans to suffer the consequences- that we don't know very well what conditions prevailed on the globe then, or even if the lvl of co2 rose , naturally, as sharply as it is doing now- because some will not admit something exists even when it knocks them over the head.

We know co2 is a greenhous gas. Not the most important - that is water - but we aren't adding water to the atmosohere at a disastrous rate.

From Wikipedia (http://en.wikipedia.org/wiki/Image:Carbon_History_and_Flux-2.png
"
The net flux of carbon into the atmosphere before the rise of fossil fuel burning may be a natural fluctuation or it may also be related to human activities such as the clearing of forests or changes agriculture during the first industrial revolution. As seen at right, the modest changes from ~1750-1850 are largely within the margin of natural variability, but the subsequent accummulation of carbon dioxide far exceeds any concentration witnessed in the last 400,000 years and may have not occurred over the last tens of millions of years." How dangerous is it to think this is a 'coincidence'?

Notice how there isn't a 'Disputed' sign there.

Everyone in the discussion has pretty much picked their side and is sticking to their position. Be glad that the Naysayers are few, though quite influential, especially in the US. In the long run the US itself will likely find itself falling behind Technologically as Europe/Asia put resources towards dealing with this issue, but certain Industries have been following that path for awhile now so I suppose that's just the status quo.

The much maligned California and its' Governator have taken the lead in the US, again. Perhaps there's hope yet for the US.

Maybe if we built a gigantic ship that could make big blocks of ice we could dump ice in the ocean and slowly cool down the planet??

You know some places around the potomic or the east river there is some evidence of an area that had a 500 year drought.

Also scientists have estimated that around 75,000 years ago that a supervolcano caused a short ice age. I watched a very good show on this subject. 3 or 4 groups of sientists all studying in different areas of discipline, all came to the same independent conclusion.

Volcanoes can do a lot more damage than most factories. We keep making cars run cleaner and cleaner, and we also keep making them bigger and bigger.

You know I really hate large SUV's. However, I do wonder what kind of solutions would actually make an improvement. I think SUV's create more heat than the average car.

It is possible that every time we build a Mall, an airport, or a highway, that we are raising the temperature of the earth by making Cement or Blacktop cover what was once Grass or trees. This may have quite a significant impact. On a hot day, stand in a grassy area and then go stand in the middle of a large parking lot.

CO2 levels did start rising about 10-20 thousand years ago, however this was following the normal trend of CO2 variations along with ice age cycles. The CO2 levels did not dramatically rise until the Industrial Revolution.

This is a very interesting claim since your views are at odd with the vast majority of scientists in this world.

This is irrelevant, because the current rate of melting will end up putting a much larger strain on humans than a long-term gradual melting would.

You refuse to acknowledge that the ice caps are getting thicker in the middle but smaller along the periphery.

Again, this is irrelevant. All that matters is that the ice caps are melting faster than they are growing. At the current rate of warming, the global sea level could rise 20-40 feet within a century. This would displace hundreds of millions of people.

You fail to acknowledge that the Sun's ouput has increased over the past 30 years when we finally have had accurate readings.

This is true, however, unlike the warming trend, there is no reason to believe it is unusual. Based on a longer record provided by tree rings and sunspots, fluctuations in the sun's output appear to be related to past warming/cooling cyclesl.

I believe there is only one Vostok Core, and it provides the exact data that has led scientists to conclude that the current warming trend is out of the ordinary. The current warming trend is not consistent with the temperature cycles over the past 400,000 years.

I just refuse to acknowledge that man's Co2 = GW, because no matter what you say, it is *NOT* scientifically nor statistically proven.

Scientifically the evidence is extremely strong. The current warming trend coincides with the current skyrocketing of CO2 levels AND with the Industrial Revolution. Graphs of the data are easy to find and the correlation between them is clear. The chance that this is all happening by coincidence (as you claim) is so small, that no rational human with knowledge of all the facts would consider it.

The sad thing about this claim is that even a thirty second glance at the data shows that the current warming trend is not consistent with any past climate activity on earth.

1. Co2 levels haven't raised dramatically outside the normal variation that has been seen through history. Furthermore, a deviation from a highly variable measurement isn't amazing.

2. I couldn't care less about what the "vast majority of scientists" believe. They get into a group-think mindset and just follow the flock instead of thinking about other things, like statistical proof. This is no different than fools who think the housing market isn't going to crash, which I said 2 years ago. Group-think rules logic and reasoning, if you let it.

3. I doubt you will see 20-40' raise in 100 years.

4. Again, you are assuming that history is a perfect predictor of the present and future. This is complete crap, as history can only be used as a guide and has to be acknowledged as an imperfect one.

5. You are saying that the industrial revolution has played a huge part, yet CO2 levels, measurable and extrapolated by man, have only increased dramatically in the last 80 years. How can you automatically assume that they are what has caused an increase? You can assume but you can't prove, yet you preach like it is proven.

6. It doesn't have to be consistant. No past cycle was the same as the previous, and IIRC, the last wasn't as high as the one before. It's called a "random walk", whereby you cannot predict it and the variations aren't explainable by any normal means.

Seriously, as I have mentioned before, show me an R2 of man's output of CO2 that can be directly measured and attributed and if it is high, then I might believe you. However, the independant and replicatable tests I have seen do not even come close. The one variable that people focus on is man, and that R2 has been low.

You don't have to do that, it will occur by itself.

I just had to make the joke about dumping ice cubes in the ocean.

The temperatures in the oceans may have a lot more to do with any kind of warming effect than any other aspect that could affect the average mean temperature of the earth in any given year.

Also Sub-Surface Volcanic Activity may work in very long cycles.

Of course everyone failed to mention that seismic activity and vulcanism is steadily increasing since 1875, and shows a VERY consistent overall pattern of increasing. Polar tilt (Chandlers Wobble) roughly correlates to the increase, though cause and effect are not entirely clear at the moment. It is not inconceivable that the wobble of he Earth on it's axis is the cause, and mans involvement though a nuisance, cannot change the inevitable.

Gases released from volcanoes dwarfs mans output in any comparison. The ratio is such that man is basically insignificant...at least statistically. We sure do think that we are important though. the Earth will survive with or without man. It doesn't care which.
