Global Warming

i agree for many reasons
also the sun is "quiet" perhaps we need to think of beginning of an ice age

http://news.bbc.co.uk/2/hi/science/nature/8008473.stm

I'd suggest reading the whole article.

Of course it's man-made.

Even the relatively small amount of CO2 in the atmosphere makes the earths surface about 59℉ warmer, which is all natural and fine and good. But pump CO2 into the atmosphere and before long the whole planet's going to get warmer!! Add 6 billion tons of heat trapping CO2 annually, globally and the effects mount up. Whether it's through oil, gas coal or deforestation etc, the concentration of CO2 in the atmosphere right now, is at a 420,000 year high, according to scientists. Just 20 years ago the level was 280 parts per million, now it's over 370.9 parts per million within a few more decades it's thought it could well be around 500 parts per million.

By the way jazzguru that films junk!

Put it this way, it fits neatly into the Ron Paul junk your fond of.

You guys really need to stop simplifying everything to make yourselves feel better. Good luck in another ten years trying to explain away more problems caused by CO2.

It's a joke is what it is. It's been discussed, dissected and ridiculed (as it should've been) here in AO before. Cheap propaganda.

This place is like groundhog day sometimes.

We humans really need to put a stop to all these volcanic eruptions and under-sea vents !

These things pump more CO2 into the air per day than human industry does in a year... I'm just not CONVINCED that humans have any effect on the GLOBAL temperature.
Nobody knows if the "warming" of late is caused by humans or just part of a natural cycle that would occur without us. Really. "They" don't know!!

Yes I did. And it's as misleading as some of the other things, in a similar vein I have seen, read and heard. That's not to say it's all wrong, but like so many documentaries it omits evidence and distorts things.

I don't have a good grasp of this area yet and my opinions regarding it are still forming, however the misrepresentation is fundamentally off the scales.

The fact is, that CO2 levels are rising through man's activities, putting huge amounts of CO2 into the atmosphere. Whilst it's true (and necessary) to have CO2 naturally in the atmosphere through oceans etc, that level is in a natural balance with other forces in nature. Until recently! Now we are adding CO2 and other trace elements at a massive pace to that approximately 600th of the atmosphere. At CO2 natural levels it accounts for a warming of the planet of 59℉, by adding CO2 the temperature has increased in accordance with the impact of adding that CO2 by on average 0.6℃ ( nothing, let me repeat nothing to do with the sun- of course the sun effects temperature and the CO2 levels in history have been effected by natural cycles-but this is NOT RELATED to the 0.6 temperature change!!!!!!) and in some areas the temperature changes are more prominent than others due to graphical location. Further heights in temperature will cause major problems. Estimates of sea level rises are about 1 metre by the end of this century, which will have catastrophic impacts on huge numbers of people and on and on.....

Unlike "An Inconvenient Truth" which distorted or omitted nothing.

The fact is that if you push up the CO2 level in the atmosphere it creates warming. The relationship between CO2's rise in the atmosphere is directly related to what man is adding, other factors of course exist, but get this part clear.http://zfacts.com/p/194.html as the graph shows. This is what global warming is all about. There are obviously going to discussions and disagreements between scientists as to how the planets relationship between natures forces have shaped the planet over thousands and millions of years. But there is no disputing this recent man-made raise in CO2 and global warming despite all the other forces which effect it.

If you and others wish to carry on believing it's nothing more than a farce, you are being mislead and will help to make the extremely serious problems worse.

I agree with you, look at the problem from different perspectives. The one true thing though, is that CO2 levels are currently rising in relation to what man's activities is putting in. This man- made impact is causing a small temperature rise which is undeniably related to the CO2 in the atmosphere and that that small rise is having a dramatic effect. If you want to believe otherwise go ahead, but remember you will be effected, and already are by climate change.

The argument that emissions cause global warming is irrelevant - it's in our best interests to pollute less. Clean up after yourself and if you don't then someone will make a law requireing you to. I'm OK with laws mandating levels of emissions and such.

I'm totally against the trade of "carbon credits" though.

Jazzguru I'm not dismissing all the scientific evidence you present, like I thought I had made clear. I will re-post when I have some time soon as I'm busy now.

Just skimmed through that pdf. It's good for a laugh, beyond that it's worthless. I truly feel sorry for you guys, but I'm sure the coal industry loves you.
Next you'll be saying oil spills are good for the birds!

Here's part of the conclusion in your pdf-

"The CO2 produced does, however, accelerate the growth rates of plants and also permits plants to grow in drier regions. Animal life, which depends upon plants, also flourishes, and the diversity of plant and animal life is increased." and "We are living in an increasingly lush environment of plants and animals as a result of this CO2 increase."

Not conventional thinking that's for sure. Maybe we should just burn more and more coal, no need for renewables, so we can have a global Eden. Funny you guys think it does so much, but that it doesn't cause any warming how convenient!

This "petition" has had problems with it's methods, qualifications, etc. since it's inception.
Skeptics

.
His reasoning for including the unqualified,

So?
Inflating a cause by dubious methods is never a good idea, no matter who does it.
Makes you wonder why.

The PDF. has had it's skeptics as well and was probably discussed here as well.

Try a search here with Global Warming in the criteria.

I'm on dial up, fucking pain.


Okay, I did a search, Threads started by an old favorite here,

Don't have time to reread these now, but I'm sure they're entertaining.

I feel that the 3 choices presented by this poll do a disservice to the topic at hand. The discussion would be more productive if not framed in such a manner.

What really matters is if changes in human behavior will avert the negative consequences of climate change. It matters less, what percentage humans may or may not have contributed to the trend.

Certainly it would be useful for understanding the subject fully. But even if it were concluded that humans contributed only a small percentage, it would still be possible that action now could lead to a drastically different outcome. The two are related, but when the topic is approached from "are humans primarily responsible?", that concept tends to be conflated with whether or not we can do anything about it.


Also, the subject is muddied when it is tied to whether or not global warming is real. In my mind, the two should always debated separately. First, whether or not the global climate change is real. And second whether humans should modify their behavior to prevent adverse climate change.

I agree with the first sentence dfiler.

The rest I'm open to.

1... It has NOT been proven that the rise is in any way connected to humans and our industry... it is speculated... but we simply have not been taking measurements for nearly long enough to determine if we are having ANY effect geologically. Maybe we are, but it is NOT A PROVEN FACT.

2... What, exactly, is the "dramatic effect" that this small rise is having ??? There have been several theories of certain FUTURE "dramatic events" that MIGHT happen... but, again, no real evidence that anything IS HAPPENING.

It's beyond me how you can say that. Have you researched it at all?

Antarctica contains 70% of the worlds fresh water which has been locked up in the form of ice for hundreds of thousands of years. Those ice sheets, often more than 3 miles high covering four to five million square miles, which is larger than the size of China and India combined are melting, cracking and breaking away. The British Atlantic Survey and the University of Colorado reported back in 1999, that global warming has lengthened the annual Melting season there by 3 weeks. The average temperature in Antarctica has been almost constant since the beginning of man. Since though, 1950 the temperature there has risen by 4.5℉, which has pushed summer temperatures there well above the critical freezing point of 32℉. If that doesn't concern you, nothing will.

This was mostly covered in the threads I posted links to a couple of posts above.

Why we keep on posting the same stuff over and over again, even though it's easy to keep a thread going is beyond me.

My point is, NONE of that has been proven to be tied to human industry.

You do realize that there have been global warming and coolingcycles fro ages, right?... these cycles have been going on long before humans even existed ... much less had any significant industrial base.

So yes... Ice caps may be receding ... but no-one has provided any evidence (much less proof) that it is caused by me. It's quite possible that we couldn't stop it, slow it, or even accelerate it even if we wanted to. Having seen the polar ice cap with my own eyes, I'm not too worried yet.

Yes, I recycle... yes, I try to limit the amount of pollution I make (my boat is wind-powered ), but I have no desire to go back to an agrarian society... I like things made of plastic, electricity, the ability to travel all over the world...


If the "powers that be" were really concerned about the fate of the earth, they would realize that there's not much we feeble humans can do about it. Perhaps they should quit spending all their money playing a global version of "my god's better than your god" and put that money into establishing a human presence OFF the earth ... I'll not hold my breath.

Do you really expect someone called KingOfSomewhereHot, would be against global warming, hence learn the facts!?

No.
I don't.

I did know that about changing climactic conditions. The thing is there used as a denial response to global warming, as if the sun is creating this current rise when it isn't. I'm sure scientists are going to come up with whacky ways of solving it, but sucking all the methane out of the oceans? Ludicrous! I look forward to seeing how they get the paste back in the tube. Good luck to them, they'll need it.

I agree about the religious wars, though I don't think religion is solely to blame, more greed and power.

I'm sorry you didn't witness anything unusual in Antarctica, others have and apparently it's quite stunning.

Planting good old fashioned trees would help combat GW, so cut back on meat and plant baby plant.

Huh?
Did I miss something?

If manmade, then manmade measures taken to halt global warming are essential. It is prudent to assume the worst, and try to deal with the worst case scenario. It's not as if we have a back-up planet we can all jump to should Earth "fail" and becomes uninhabitable.

If the principle causes are not manmade, then we have nothing to lose, apart from rendering a lot of 19th Century techmology obsolete. Pursuing "green" technology is win win all the way.

The real reason why some people are "doubting" the manmade hypotheses is that solutions require international regulations with enforcement, and this doesn't go down well with so called 'free' market/laissez faire/Friedmanesque ideologies which have become de rigeur throughout much of the world during the last few decades. Their arguments are "politics bracketed by science".

These Ron Paul types etc will do anything to defend their bull, including selling the world down the tubes. So be it, but they share the blame for inaction and it will forever stain their own legacy, indeed ruining it as this global disaster unfolds.

I'm skeptical of the scientists trying to fix this problem. It's a bit like trusting the current politicians to get us out of the financial mess, they over time have caused. I can see disasters in the making as man tries to meddle with nature, yet again not knowing what the long term consequences will be. That said if push comes to shove some things may have to be tried. Certainly renewable energies is the right path though, but there not currently as green as is supposed. Take solar cells. There made from several rare minerals that require hundreds of tons of mining. All the equipment is made and powered through the use of oil.

Hydrogen takes a huge amount of energy to produce (more than is obtained from it) as there are no underground reservoirs of hydrogen.

It currently takes about 1,000 gallons of fossil fuel to produce one acre of corn. One acre of corn yields about 328 gallons of ethanol. There is other data suggesting the ratio is much better than that however (up to 1.34 rather than 0.59 which relates to BTU's to output of energy), but still it's estimated that it would take nearly the whole area of the US to be covered with a corn crop to run it's vehicles alone.

Obviously these alternative energies are advancing and are needed, but getting off oil is still a long way off.

You can't "prove" AGW with 100% certainty. But you can make probabilistic statements.

The 2007 IPCC reports stated that, it in very likely (p > 0.9) that humankind is causing the majority (p > 0.5) of the global temperature increase seen to date.

About global warming, perhaps not since the system is certainly more complex than a bread box filled with steam, but we have plenty of evidence that humans affect climate geologically now and well at least since agriculture, which is to say it is naive to suggest that humans cannot have an effect.

Industry Ignored Its Scientists on Climate


It's always someone else's fault.

I'm looking forward to reading your posts, in a few years, how a bunch of global elites caused global warming to 'bring down America.'

This is near your part of the universehttp://scrippsnews.uscd.edu/Releases/?releaseID=876 So go ahead, leave all your lights on and call global warming a farce, designed solely to deprive you of your constitutional rights. Remember that waters needed to grow crops too, about 60 gallons for a pound of wheat as opposed to 13,250 gallons for a pound of beef. Looks you might become a vegan, if your not already.
