Global Warming: fact or fiction?

[areon]

its a natural thing
Hey idiots! the world has been changing for thousands of millions of years and we didn't do anything to contribute to it. there was a time were most of the earth was covered in jungle and had tropical heat everywhere around the world and we weren't even anywhere near as evolved as we are now. i agree when people say that coal and oil are damaging the earth but not the heat and the ice caps. you people just say its a problem because it is the new fad to be concerned about the enviroment. for God's sake we are a small force compaired to the forces of nature and its nature that determins the enviroment. we are just a small part of the equation. so don't believe everything you hear on TV theses days. and you lot are the adults...

We do have the capability to change the world. The Sahara Desert wasn't always a pile of sand and conflict. Have you heard about what China is doing with the Yangtxe River dam? Have you heard how much water and people are being displaced? The weather patterns shift when ecosystems are transformed. Why deny this correlation? Does anyone know what is going to happen when the Oglala aquifer is used up? There are so many examples to draw from that it is staggering.

[Anarkistsdream]

Amen... And what about destroyed coral reefs that MAN has bleached??? They helped to contain greenhouse gases...

Anyone who doesn't believe in global warming has obviously never taken any sort of meterology or geology class.

close to the mark all them that made that report that came out yesertday was all us tects they did not take into acount what the rest off the world is saying still maybe the us tects might catch up with the rest of the world in 10 years time all they saying what the national reseach council said 35 years ago go on there web page and look it up
they know how to stop global warming its a case do they dare to because if they did and that world temp drops to fast it throw us in to an ice age

Guis, you actually understood what all those jumbled letters meant???

[Guiscard]

Not really they were muffled by the sand...

[WL_southerner]

ok plane has i can be the report was done by us (untied states ) tects (scientists ) and they only repeated what national research council said 35 years ago ,
they know the earth is going though a warm cycle but man is making it hotter than it should be at the end off every warm cycle there is an ice age
the 2 evils are is that we warm up pass the point off no return and end up with a planet like venus or we go into and ice age
whitch would you choise

[Stopper]

As far as I understand it, the next ice age (were it to ever happen, global warming notwithstanding) would be a couple of thousand years off. On the other hand, human-induced global warming will cause significant change in just a few decades.

So, you know, you can sort of see why people talk more about global warmings than ice ages.

[Guiscard]

Southener. What report are you talking about? The INTERGOVERNMENTAL one compiled from the research of scientists ALL OVER THE WORLD?

Got any reports on a similar scale to cite? Actual examples not waffle...

The clincher for me is this, a variation on pascals wager...

Two options:

a) We assume that climate change IS being accelerated by human factors and we try to cut emissions and and work towards a solution

OR

b) We decide there isn't enough evidence and so carry on polluting.

The results:

a) If climate change is a reality then we've slowed it down and saved our skins. / If climate change is a myth then what have we lost? Business dollars from big polluters? That's a bit less important than the entire planet! Plus I'm sure no-one is going to argue that cutting pollution is a bad thing for the environment in general, even if it doesn't affect climate change at all.

b) Climate change exists - we're fucked. / Climate change doesn't exist - No problem, but we're sure to have harmed the environment in some way.

Here's what I feel from the Info I heard
Greenhouse gases (which seem to be causing global warming) are made up of mostly CO2 and H2O
Now correct me if I'm wrong but, DOESN'T EVERY ANIMAL BREATH OUT CO2?
and isn't our earth 70% H2O
So I don't think humans are the sole reason why global warming is happening
Plus there was an article that stated every time a volcano errupts, the amount of pollution thrown into our atmosphere is equilivant to 1,000 years of car pollution
I have also heard that the ozone layer is healing itself

Firstly H20 is water and I’m pretty sure that’s not a greenhouse gas. CO2 is produced by animals but plants also take it in through photosynthesis but a combination of fewer trees and more CO2 being produced by fossil fuel burning means that this is being knocked out of balance

The ozone layer does heal itself, but at an extremely slow rate, and certainly not as fast as it is being destroyed

first, water is a greenhouse gas, all a greenhouse gas has to do is be able to absorb IR radiation, which is what both H2O and CO2 do due to their molecular shape(bent), second, the ozone layer is not relevant to global warming, and it should be repairing itself after the montreal? protocol to phase out cfc's, though it wont be back to where it was for another 100 years? not sure on that.

[WL_southerner]

if you look at the names that was behide that report they all came from usa and they called it mutinational and all they done was to say the same thing as the national research council said 35 years ago
usa has 2 ships call mv hero and mv carabeain sea that belong to the national research council that report did not say any thing about there findings the national research council is made from every country in the world and been around since 1949
has for the next ice age that could happen any time it just takes the right events to happen at the wrong time it could start tomorrow,next week,next mth.next year,or when ever we just dont know when it will happen
global warming is earth cycle and man is making it worst

[Guiscard]

global warming is earth cycle and man is making it worst

That's what the report says... and what the majority of the people in this thread have been arguing for... a

[vtmarik]

To those who never passed science class:

H20, water, has three molecular forms:

Solid, which we call "Ice"
Liquid, Which we call "water"
and Gas, which we call "water vapor" or "steam"

If you've ever been outside on a really humid, muggy day you know about H2O in its gaseous form.

EDIT: And yes, it is a greenhouse gas. Water has a high specific heat (look it up if you don't know what that is), and stores heat very efficiently.

So?

So?

I posted that for the edification for the people who keep insisting that "H2O isn't a gas."

[WL_southerner]

in the 13th cent we had a warm global temp that was 0.014 lower that it is today this came to an end in the beging of 14th cent they now know it was all down to a volcano (kakatoia) the world temp drop putting us in what is known has a mini ice age like i said before this volcano (kakatoia) is due to do it again soon
they know this volcano had started the last 2 ice ages it time with the slowing down of the gulf stream like the gulf stream is doing now slowing down and getting wider

[Guiscard]

Southerner what are you arguing for? No-ones saying that climate change is entirely caused by man, just speeded up. Even if it has happened before the results this time will cause immense suffering, refugees, starvation, drought etc.

Yeah and?

We can stop what we're doing right now, and the process'll still be going on. Temperatures will climb, the oceans will rise, and the same people who would be completely fucked in a few years will be completely fucked in a few dozen years instead.

How is that better?

[jay_a2j]

Well, according to what I heard on the radio today. There is NO evidence that global warming is occurring. In fact the Earth has been both colder and warmer than it is now. Sorry Al Gore, you'll have to come up with another way to become president.

And I assume this radio person had degrees in Climatology, Environmental Science, and Meteorology, and had extensive expertise in the field of global climate change and the factors surrounding and causing it?

I can also then assume that this person was on a nationally syndicated and/or recognized radio program that is transmitted via satellite to multiple stations and is knows for its objective and balanced views on the subject matter.

Of course human activity is causing a great part of the global warming, What do you think? That 6,000,000,000,000 people with all those machines and factories doesn´t cause an effect on the planet?? We are fucking this planet big time, and don´t try to take it on some other events, al the nature´s contaminant events happen occasionally, we are a constant. Ozone is healing it self beacuse WE stopped using CFCs in a significant way, global warming is not less than human caused problem, with a little help from nature. If humans weren´t in the planet the next ice age or the climate change would start feeling in like 3 or 4 million years from now.

We aren't the cause, and we aren't responsible for any majority of the effect. Do you know how long we have been pumping smoke and crap into the atmosphere? Almost 300 years. (Though some might argue 8000 Years, what with livestock flatulence and all.)

How old is the Earth? It's somewhere in the neighborhood of 4 billion years old.

How many ice ages have their been? Four major ones:
http://en.wikipedia.org/wiki/Ice_age

We aren't that important, let's stop being so damn egotistical about our power to shape the world.

EDIT: For the sake of scale, let me numerically point out that we've been on this planet for approximately 0.0000075% of its lifetime, and yet we're the one's who are doing all of the damage and we're wrecking the earth and we're to blame for everything that goes wrong. Right. And it's all Bush's fault that Congress kept giving him money.

It was a Scientist on the Sean Hannity Show. He stated that the scientific evidence does not support global warming. He also stated that, were as some ice formations may be getting thinner (due to melting) others are getting thicker.


Its all bunk. Stop being scared and go buy an SUV.

Firstly we have only been causing a large amount of pollution for 150 years and cars weren’t that common before 80 years ago, and even then factories caused poisonous smogs in cities like London

Earth is around 4 million years old and depending on what you call a major ice age(all ice ages were pretty major) 4 may have happened-so what?

and yes we have been on this planet for a very short time but that is no reason to say we aren’t changing it, life changing the surface of the earth is not a new thing.-Very early during the stages of life, one plant evolved which wiped out 90% of life on earth by being the first to release oxygen, a poisonous gas to most of the plants at that time. It is because of that that we have the ozone layer and it allowed animals to evolve.

Finally as for livestock flatulence ect, plants take in a large amount of carbon dioxide but as we now have significantly less plants and a huge increase in emissions from cars we are upsetting the balance.

i think some of you need to go back to school and learn a bit more the earth is not 4 billion years old its alot older 35 billion years ago the air was carbon first plants was about in the shallow sea waters about 20 billion years the first muti cell soft body in the seas about 15 billion years ago first land plants 10 billion years ago the first ice age and there been an ice age at the end of every age on the earth history
of couse we going though a warm time now but man has not help in one way we are making this planet hotter but if we did't then we would off had an ice age along time ago, man been making this world warmer ever since he found out how to light fires
