Global Warming: fact or fiction?

[Hoff]

Global warming is happening, and its human-made problem. When it happens naturally it happens at a much slower rate then it is happening at the moment.

How can you prove that? Were you alive 1000's of years ago taking accurate measurements of the global temperature? No, you can't and you weren't. There is no way to tell how accurate the estimates of global temperature are over the course of time.

Particles of air frozen in the Antartic for several thousand years have been studied by scientists from all over the world. Thats how they and I and everyone else know.

PS: my friend is so liberal that you could drown in it. would that have anything to do with the way he reacted?

YES!!!!

I'm liberal as well, and the reason we react in such ways is because we obviously know better than everyone else that doesn't agree with us, and when you think you're better than us- it's just becuase you're a snotty asshole.

But anyway, we are causing global warming- wanna something else though? We're cooling the world even more. The weeks after September 11, scientists all around the globe took part in measuring changes in the world's atmosphere since all flights were held for days, and even after that only a few planes were allowed to fly. ou know what they discovered? The clouds caused by the plane engines hypercondensing the water molecules in the air account for more than we thought. They were expecting a few tenths of a degree change, but that wasn't even close. It was whole degrees, in much of N. America the average temperature shot up TWO DEGREES. In a few places it rose as much as FIVE.

This may not sound significant- but all those people that are freaking out about degree changes are mentioning that SAME amount of change occuring over a period of DECADES. Yes, there is a reason to be concerned of global warming from exhaust of most vehicles, but if we ground planes or eliminate their tail-clouds the effects are even more disastrous. (scientists are working on applying military technology, which eliminates those clouds for stealth, to passanger airlines because they believe them to be an 'eyesore').

But yea- if you say humans aren't causing global warming... what a bunch of shit...

[Zackismet]

Oh, the other way we're COOLING the earth is through the melting of the ice caps. The ise caps are not melting because of a temperature change, but because of their expose to UV rays. Unadultered rays pound at the caps, energizing the water molecules into liquid form. However, these rays are deflected, for the most part, from the white ice back through the ozone hole.

The problem with the melting ice caps is the freezing water traverses the ocean's systems. The oceans are our main defense against global temperature changes, water's high heat capacity makes it very difficult for water to change temperature from outside forces. Rather, it regulates the outside forces. If it's an extremely hot day, the water takes in much of that heat, cooling the air. And during the winter, water gives off heat until it freezes. The unsurmountable gallons of water that go through the cooling and heating process of the seasons is what keeps us from frying or freesing to death.

BACK ON TOPIC- the freezing water from the ice caps being introduced into our oceans is slowly cooling them. Since worlwide average ocean temperature is lowering, the water takes in more heat from the surrounding air.

Once again though, this change is not occurring as fast as our catalization of global warming.

You're referring to "global dimming", Zackismet. This is the idea that from aeroplane contrails, and other forms of air pollution (factories/power stations belching out smoke), human pollution is reflecting back a significant amount of sunlight into space, much like your Mr Bush's Gigantic Space Mirrors.

As far as I can remember, the idea is that if we did massively cut down on carbon emissions overnight, then while global warming would carry on for some time unabated, global dimming would stop almost immediately, which in turn would accelerate global warming even faster. So everyone should get in their cars and planes, & save the planet.

Either that, or it's a further reason to cut down on emissions as quickly as possible. I prefer the first scenario, it's much less sensible.

[Stopper]

More importantly, did it work?

Not really, a micrometeorite hit it and turned the mirror into a giant death ray that vaporized several scientists and cut an entire arena in half.

Hmm, but if that death ray could be made to point at terrorists, then the mirror could serve a dual purpose. It could fight the War on Global Warming AND the War on Terrorism. Twice the bang for your buck!

[Zackismet]

Read State of Fear by Michael Crichton.

I hope you realize Crichton was criticized unmercifully for this book. Scientists ridiculed him to no end and anyone in the community, even those that agreed with him, refused to associate with him because of the innacuracies printed in it. Well, not inaccuracies, it's the way he interpreted the data he used- that was the innacurate part. There were so many variables he just ignored, it's shameful.

[Zackismet]

So everyone should get in their cars and planes, & save the planet.

yes, i recognize the sarcasm, i just want to comment on it. We've cornered ourselves. If we stop emissions- global warming explodes, if we don't- it'll come at us at a pace much opposite of a blietzkrieg, but just as unstoppable. The hole that we have created will not heal itself fast enough to stop global wraming if we stop emissions, but it will only continue to get bigger if we don't.

and i'm not sure if it was you- but someone said The Hole doesn't matter... and that's just absurd. The UV rays not reflected by the ice caps become trapped under our emissions and coninue to reflect between our poison clouds and Earth. Those emission clouds are just as effective at trapping UV rays as they are at blocking them.

c'mon science! save our asses!!!

planes being grounded did not make much diffrence the world ave temp stayed the same just because one or two places got hot do not make it global
the atlantic sea ave yearly temp is up like just off the silly islands ave temp is 15c when the normal temp is 12c in october
world temp have been going up very slowy some thing like 0.01 in a year it may not sound alot but over the couse of years they add up uk has land and temp records for the last 200 years you can find copys of the records in the natrual scince meusuim in london
and its not just ice core records there are other records that showed whats been going on in the earth temp history there are peat and wood rings records to back it all up even in rocks with tell you whats been going on in this planet life like the very first ice age was 10 billion years ago
when 90% of life got wipe out on land and sea and we been having hot periods and cold ones ever since

Just thought I'd give a link to this in todays news:

Warming 'very likely' human-made

[Lt.Mustard]

heres some evidence for ya, in minnesota, fricken minnesota! land of igloos and blizzards (yea i know you all saw fargo) we have had less than six inches of snow this year, and barely over a foot total for the last couple years. sure, people from oklahoma and missouri might think the next ice age is setting in after all those freak snow storms, but reality is that the climate is definiteley being effected by our (humans) presence on earth, and we need to do some serious shit about it.

[trestain]

hey Lt.mustard just wondering if you'll ever gat promoted to a colonel

[Lt.Mustard]

not if i keep playing like i have been lately

[Bertros Bertros]

Today the IPCC (Intergovernmental Panel for Climate Change) have published their climate change report for 2007...

http://www.ipcc.ch/

They have concluded that the current warming of the earths climate has a greater than 90% probabilty of having human cause with the following projections...

- Probable temperature rise between 1.8C-4C
- Possible temperature rise between 1.1C-6.4C
- Sea level most likely to rise by 28-43cm
- Arctic sea ice disappears in second half of century
- Increase in heatwaves very likely
- Increase in tropical storm intensity likely

Interesting stuff.

[WL_southerner]

yes i did read it but did you look at who done the report i mean the people behide it all all was from the us they did not inclued any thing that the national reseach council or british antarctic surrey and a load of other govern bodys
whitch most are saying its part of the earth cycle but man has made it hotter than it should be and that we are long over due for the next ice age and probely down to man why this has not happen yet
they know how to get the earth temp down and repair the ozone layer at the same time and that is a simple act off fine spraying sea water above the jet stream but there is a problem here if they done that and the earth temp drops to fast it with throw us into an ice age the other evil is if left alone the temp will get to a point where there no turning back and we end up with a planet like venus
man cant live on a planet like venus but man live though an ice age they have done all ready 2 off them
why they have not done it yet is down to goverments they dont want to see the shift of power from there country to another

[Backglass]

It's all over the news today:

"Warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global mean sea level"

http://blogs.usatoday.com/ondeadline/20 ... ange_.html
http://www.abcnews.go.com/Technology/Gl ... id=2843621


But, I am sure it's all wrong and just made up lies.

[WL_southerner]

did you read my last post backglass that info that they went on was only a small part they did not look into what other countrys are researching best place for info on global warming is the national reseach council it is a muti country council from all over the world

[HoustonNutt]

I am too lazy to read this whole thread, but which shiteating retard voted "Global warming is NOT happening?"

The recent report is 'Intergovernmental' - as in between all governments - Scientists from all over the world. Believe me, the US don't want Global Warming to be the scary reality (look at Bush's reluctance to sign Kyoto) - It harms American big business! Unfortunately its a bit hard to just stick your head in the sand now. Most of your post doesn't really make sense but you seem to be saying that the rest of the world have some kind of brilliant insight into climate change that America is trying to repress...

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...

although i thinks its natural i agree. its happening Mr Shiteating Retard.

Probably a fact, but man has little to do with it.

wait wait wait - and you other lot:


Today 2,500 scientists from 30 countries put their name to a document that states unequivocally that mankind is changing the climate of the planet.

2,500 scientists. Who study this shit for a living. I doubt any of you are scientists, let alone climatologists. How can you possibly continue to deny this? Fundamentalist godbotherers i can understand - they seem able to deny anything at all despite evidence to the contrary, weight of opinion, common sense etc etc - but come on. It's happening. What more do you want?

[WL_southerner]

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
