meteors or volcanic activity alter the atmospheres content on occasion, and causes an ice age

there have been many ice ages, and they come in natural cycles. the fact is, the current global warming trend is going AGAINST the natural cooling cycle.

there are basically 3 major cycles that control climate... here is a few diagrams from the Ruddiman 2003 paper discussing global warming and how it relates to natural cycles and human influence...



This graph is a comparison of atmospheric methane levels to the insolation (absorption of energy from the sun) cycle that is controled by precession, the 23,000 year orbital forcing cycle. note the abberation at the end of the last cycle, highlighted in the graph below:



methane levels compared to orbital forcing cycles. note the digression from the trend at 5000 years ago that coincides with the beginning of large scale irrigation of rice and other crops.





Three graphs of CO2 levels. notice the digression from the projected orbital forcing of carbon dioxide at about 8000 years ago. also note the sharp increase in CO2 levels in the second two graphs with the rise of the industrial revolution ~200 years ago

(the difference between A and B represent the original theory (A) that the bulk of CO2 has come from the industrial era, while B represents the newer theory (Ruddiman) (B) that anthropogenic influence began with the onset of agriculture.



Methane, CO2, and Temperature projected, respectively. The "pipeline" refers to the lag between the release of greenhouse gasses and subsequent temperature change.

saying that "the scientists of the world don't agree" is ridiculous. If you can find me one situation in which every scientist in the world agrees, other than something like "human beings breathe oxygen," I'll give you a shiny new quarter.

MOST scientists agree what global warming exists, and most of those agree that it's at least partly due to human actions. See, I don't think many reputable scientists would say that human beings alone are causing global warming. They know as well as we do that the earth goes through warming and cooling cycles all the time. However, as smath said, and as many many many geologists and others have said, the current trend far out paces anything before it, and it's not likely that coincidentally we're outputting more CO2 into the atmosphere than has ever been put out in history.

That is a mild exageration. Mt. St. Hellens released more CO2 than the whole of the human race does in several years. A forrest fire in Florida a few years back released more CO2 than the whole of the human race did in the following eight months. So while we are not the largest contributor of CO2, you are right that we are a new player.

All that having been said, the debate about global warming is largely academic. I don't believe many reputable scientists are arguing that global warming will have sufficient impact on humanity to justify doing anything about it beyond perhaps installing wave barriers in a few strategic cities.

Of course MOST scientists agree global warming exists. because it does. What is up in the air (hehe snort) is how much of an effect humans actually have on it.

But Lokken, if you agree that global warming does exist, then your next logical step (assuming you see it a prblem that will cause large scale difficulties in the futuer) would be to look for ways to control it. Since we cannot hope to control the natural causes of CO2, the only thing lsft to do is control the CO2 we cause.

but then doesnt the arguement shift back to what they have been saying... what matters is what impact we do have, if we only have a limited time on this earth as we know it then the benefits of our reducing the emissions should outweigh the economic hardships of not doing so, assuming the global warming is going to happen anyway.

Bull-Shit. Deal with what you know. We, as a species, have developed many useful technologies over the past 5000 years to deal with the effects of global warming, whatever you say they may be. However, we cannot do this unless we are able to use the tools at our disposal, namely fossil fuels.

Possible effects of global warming:
1. rising oceans - as the oceans are predicted to only rise a few inches, problems will only arise during storm surges in un-protected areas. Solution: protect currently unprotected areas.
needed technology: concrete sea walls, requires cheap energy such as from Coal

2. rising surface temperatures - as the predicted temperature rise is only a few degrees, problems will only arise during heat-waves. Solution: more equitable distribution of air-conditioning technology
needed technology: affordable electricity, requires cheap energy such as from Coal

3. shifting weather patterns - if the temperate zone of the planet shifts northward, human assistance may be needed to relocate plant and animal as well as human agricultural systems to new areas. Solution: construction systems capable of constructing new irrigation systems and distribution systems to access the necessary resources
needed technology: affordable portable energy supplies, such as from Oil

4. sudden restoration of an Ice Age - If the temperature drops suddenly, the solution is obvious. Relocation of population centers closer to the equator and more widespread heating technology. See above solutions.

Let me know if I missed any. The fact is, regardless of whether or not we are causing global warming, it is happening. And we are probably going to need every tool in our inventory to deal with possible future shifts. Fossil fuels are THE most potent and useful tool in our tool belt and to restrict its usage right when we might need it most would be suicidal. With cheap energy available, the human race can quite comfortable stand up to whatever mother nature throws at us, just ask Holland.

Oh I absolutely agree. I fully support alternate fuel research and would love to have me a hydrogen powered truck that just spits out water vapor.

We definately need to be responsible with our technology and always be aware/researching cleaner more efficient ways to do things.

I just dont agree with alarmists and people who think we are setting the planet up for a doomsday ice age. I just dont think we have that large of an effect on the cycles of the planet.

As for Kris:

The world could NEVER work, much less perfectly. All we have are present solutions to current problems. Government has never been able to respond quickly enough to changing circumstances to make the "world work," as a matter of fact neither have markets, but they seem to do "better." But only a fool thinks anything involving fallable human beings will work perfectly.

Tarzan, I haven't been impressed with anything he's posted in this forum.

Previously stated points:

Quote :
"1. rising oceans - as the oceans are predicted to only rise a few inches, problems will only arise during storm surges in un-protected areas. Solution: protect currently unprotected areas.
needed technology: concrete sea walls, requires cheap energy such as from Coal"


Predictions range from a few inches to several hundred feet depending on whose model you go by. Furthermore, covering all the developed eastern/western/gulf coastline with a sea wall is not only expensive but terribly ugly. On sheer scale, this is impractical.

Quote :
"2. rising surface temperatures - as the predicted temperature rise is only a few degrees, problems will only arise during heat-waves. Solution: more equitable distribution of air-conditioning technology
needed technology: affordable electricity, requires cheap energy such as from Coal
"


Increasing coal use would also increase our output of dangerous gasses to the atmosphere which in turn *could* increase global temperatures even more. Currently, ozone is created by mixing smog with gasseous, natural outputs and that problem would only increase by using more on coal power plants. If we don't get hotter, our air quality in cities will definitely suffer.

At the very least, you could of suggested nuclear power.

Oil supplies are finite and by the time global warming or "shifted weather patterns" become a very noticeable problem, Oil might not fit under "affordable."

Relocating populations centers is not easy. I'm just going to leave it at this.

Fossil fuels may be a direct pathogen with global warming. Increasing their uses is not an acceptable solution. You started your post talking about how the human species developed technologies to adapt nature and ended by concluding that we have to use ineffecient "tools" that may very well have caused our environmental problems in the first place.

Government may not be able to respond quickly to problems but it is the only entity that can tackle very large and very global issues. Specifically, the US government could in fact spearhead a lot of environmental initiatives in conjunction with the private sector that would lead to a gradual sustained decrease in US pollution.

No magic is needed.

I am an engineer. And as an engineer I am a wiz at math. What you fail to realize is that there is a radical difference between energy conversion efficiency and financial efficiency.

The average human consumes far fewer calories per day than can be extracted from a single gallon of gasoline. Gasoline is able to supply such volumes of energy with no effort on your part beyond earning $2.25 in wages.

So what if a gasline engine barely attains a thermal efficiency of 10%, its financial efficiency cannot be denied.

As an engineer, they do not pay me to maximize thermal efficiency, they pay me to minimize costs and maximize revenues.

You are begging the question. Your assertion is far from defensible given the available history. Even if you are right, the average automobile is owned for less than 10 years. If it turns out that my car which I have owned for 10 years is no longer cost effective, I will scrap it and buy one that is.

How the hell are you replying so quickly!?!? You don't give me enough time to rethink what I wrote!

And, no, the most cost effective form of energy is the form of energy that is most cost effective. Nothing else matters but costs and benefits. Gasoline is still cheap, obviously cost effective today. And using the 10-year contract rate I deduce oil is going to be equally cost effective at that time, barring unforseen changes.

Which is why you need to change your major to Math right now.

Increasing demand for a commodity that will not go into increased production will raise its price won't it?

Consider a year ago gas was nearly a dollar cheaper here in NC and I'm willing to bet a year from now it will be a dollar more expensive.

It is not a viable energy source, and your ideas are terrible.
