Global Warming

[galaxyAbstractor]

What do you think about global warming? Does it exsist or not? I think it's exsisting and we are causing it.

 

[Sharky]

I think that it's part of a natural cycle from the last ice age, and there's no way of assessing whether any species is having any effect, based on there being not much to compare it to!

Michael Crichton - State Of Fear is a pretty good book with loads of references on global warming etc if you wanna read up on it... And it's a good read too. And Wikipedia has bucketloads of information, a rather large page of scientists who oppose Global Warming theory, and an equally large page of those who agree with it.

 

[Thewinator]

I too believe its a natural cyle.
I believe I read somewhere that during the last ice age the CO2 concentration was higher then it is atm.

 

[GamingX]

I don't think we are in any imminent danger as of now....If it reaches dangerous levels, then we can think about it. Why do we have to break our heads over it???

 

[intheclutch]

Ah global warming...such a fun topic...even if the entire globe isn't warming. I've also heard it called climate change, which is just as fun because the climate has always been changing.

It is happening, but I'm not sure we have that much to do with it. Jupiter's climate is also changing, and last I checked, no humans live there. I believe Mars' ice caps are melting faster than ours...again, no humans there.

What Al Gore said in his movie and what I've seen in so many documentary is that the greenland ice will melt down in the sea and cause the Gulf Stream to stop and cause an iceage over europe btw 2010 and 2020. This happened year 1300 too when the ice over east canada melted down in the ocean. I think it should happen naturaly but we humans causing it to happen faster than it would have.

 

[kelieth]

Of course It exist, but we are the problem, if we want we can stop it

I agree, as it takes time to change and/or prevent it.

Global warming is caused by greenhouse gases, Carbon Dioxide (CO2), Methane (CH4) and some nitrogen thing *I personally don't know the makeup*, which create a layer on the earth atmosphere. These gasess are produced from burning of fossil fuels, oil, coal, fuel and so on. The production of these gases creates that layer on the earths atmosphere. Now as the sunlight comes from the sun into the earth, it goes in and now when it goes out, half of that heat is trapped by this layer formed by the greenhouse gases and the rest leaves the earths atmosphere. Now this heat which is trapped inside is causing a rise in temperatures worldwide which causing the polar ice caps to melt. Also global warming has nothing to do with the o-zone layer.

Personally, I believe it has been quite a major problem in the past 5 years. Even though there is no statistical data of about 200 years ago to compare the temperature of the earth now and back 200 years ago I still believe its a big issue in society these days. I mean when the new generation grows up and the old generation dies they've lived their happy days although we now seem to face more problems than ever before. I mean we will suffer the impacts of global warming if people nowadays don't decide to do something. Maybe not use but are children for sure. There is the Kyoto protocol which seems to help a little but thats only in Europe. USA is the biggest greenhouse gas producer. Although China has began to find other alternatives i.e the Three Gorges Dames, in Shanghai which are totally using renewable resource and will prove like 12 % of china's electricity power, cmon that a lot of damn power for a big country. America hasn't done jack ****, they just chit chat and thats it. Considering alternative fuels, nuclear which is very risky, i mean if it blows up huge radius of people get pwned in half and toxicated so its dangerous.

By the way, I am from America. So don't call me Racist or some crap like that. This is a huge issue and we *America* are doing CRAP about it...

If we want we can stop it

You think we can stop a climate change? :nuts:

Thats like saying, if we all run in the same direction at the same time we can stop the earth from turning.

Obviously thats a load of bull.

Thats like saying, if we all run in the same direction at the same time we can stop the earth from turning.

Obviously thats a load of bull.

THATS a load of bull, because there aren't enough of us. But if the right force were applied, it would be possible.

On the main subject however, of course there is global warming, and cooling, and general climate change. That has happened all the time and will continue to happen long after we are gone.

The point is however: is accelerated climate change happening?

Simple answer, yes and we're causing it (as a species).

The world and its creatures can adapt to gradual change. But this is change happening rapidly (in the grand scheme of things). Ice caps didn't melt as fast as they are doing now 500 yeas ago. And the ice that is melting now is farther north (in a place that is supposed to be colder) than the ice was 500 years ago. Of course thats don't to our industrialisation and increased energy consumption (and waste).

We could go on all day about. Years actually, as the case has been.

The facts remain:
accelerated climate change is happening
we are causing this
unimpeded, its going to put a lot of land underwater (and largely unusable)
this will cause overpopulation
it will put a strain on resources
there will probably be more wars based on this (rather than other issues).

There are already islands in the pacific nearly drowning out there. Islands that have existed for hundreds of years, and aren't volcanically shifting, are dissapearing beneath the waves.

The sad thing is, unless the biggest offender in all this: the USA, signs up to an sticks to an energy effeciency drive, things will probably continue as if nothing was changed. Towards a gloomy looking future.

Why pick on the USA though? Per head of population, they are the largest consumers of all natural resources and produce the largest amount of "greenhouse gases." And, last I checked, overall they still produced more of these gases than countries like China or India, who have 5 times the population.

Without the USA doing anything who, with all the technology, could make big changes very easily, the other countries are just like "If big US of A, 'leader of the free world' won't do anything, why should we?"

On that note: can I just poll the nationality of those who don't believe in global warming?

 

[Thewinator]

THATS a load of bull

Thats exactly what I said.

On that note: can I just poll the nationality of those who don't believe in global warming?

If by that your sugesting I'm an American...
I can proudly say, nope I'm Dutch.

Climate change has always happened, always will. So, I'd just like to ask then, where on earth is the proof WE had an impact on it? I find this really funny, because it's like Y2K all over again. People are scared of the world ending because of something normal triggering a cataclysmic, world-ending event, and yet 1) there's no proof of that happening, 2) we have no record of anything like that happening earlier in history, 3) everyone seems to think we can avoid the world ending when that's a dream and 4) everyone will forget it eventually because it didn't happen like it was meant to.

 

[galaxyAbstractor]

Here are some pictures that show what CO2 causing:

this is the normal happening:


The heat goes in to the athmosphere and bouncing out again.

This is what happens now :


The heat comes down to earth bouncing on earth then bouncing once more on CO2 and do so till it disappeare. Everytime it bounces with the CO2 little bit of the heat disappear too. Without fossil fuels we haden't produced that much CO2 (carbondioxid).

 

[intheclutch]

Bad science!

Your "normal" isn't normal at all. Without "greenhouse gases" we'd be in trouble. The earth would be uninhabitable.

 

[nakg0d]

In my environmental class, I argued that all we need is a volcanic explosion to send out a large dust cloud into the sky to block out the current radiation that the sun sends through our atmosphere.

Of course, this was based on what had first caused the Earth to have an atmosphere in the first place; that's why it would be somewhat logical to do such a thing, but *shrug.*

It is true that the amount of ozone is decreasing..

 

[Xemnas]

It is true that the amount of ozone is decreasing..

It is true, I don't think anyone will deny that. But fortunately we have sunscreen, which does help with blocking those evil UV rays and all the little nasties (i.e. skin cancer) that come with it. As long as you use 30+, of course

Look at this picture about the temperature:



When the car come and went popular in the 1920's America (also reffered as the "jazz age" or "roaring twenties" (in Europe "Golden twenties") The temperature went higher. At the end of the second world war 1945 the peoples couldn't buy new cars and fuels to it so the temperature went down again. Some years later the car went popular and large industries come and the temperature went higher again.

This picture show the temperature over the normal:


Some translated text from the swedish wikipedia:

The viktigaste of these is build-up of amount carbon dioxide (CO2) and second växthusgaser ( formerly carbon dioxide enter into in växthusgaserna also CFC vattenånga and go fishing ).

Hmm stupid online translator. Pfff "go fishing".

The most important of these is build-up of amount carbon dioxide (CO2) and second Greenhousegases ( formerly carbon dioxide enter into greenhousegases also CFC water vapor and methan ).

What will happen:

Scenarierna are building on climatemodels at a indeed measure of uncertain. Distinctly interacts yet that area as already gets very much rain was growing rain while the oppose are counting in already arid region , in both autumn with potential catastrophic sequel. Temperaturchange expect become major on further north respect southwards latitude than in tropics and landregions warm up more than ocean. Already now able ascertain that global warming are going fast in Arctic than class point average for whole world. The reduce differences in temperature among the tropics and polareregions able earnestly move the bigscale currency in ambience which is the primarily driving for lowpressurearea in major component of the world.

One unseremoment is the hydrological and klimatological fenomen El Niño as with equable interval are changing stream in central pacific ocean , which in its luck move weather in almost whole world. Misgivings find if that a vigorous global warming should affect El Niño - cycle and in worst case breed El ninõs as are lasting in several decades or do El Niño permanent. A such alteration should poll giant consequences for climate in the world , but risk assess as somewhat low.

Under IPCC are mastering earth a global temperaturechange on approximate 2,0 Celsius devoid that followed are becoming catastrophical. Wide major temperaturechanges are counting with that a rank procceses in nature enhances global warming further. To example able permafrost in tundraregions defrost and extricate huge amount methangases as contributing further to green house effect. A boosting of melting of inlandice on Greenland and ice in Arctic ocean is second example as should increase the waterlevel in sea but also re inforce global warming , as fluent water are absorbing more sun radiation than what ice can do.

This has been translated by machine and HUGE gramatic incorrectness will occor.

I think it's more of a marketing trick of the big corpotations in order to sell more "ecological" friendly products and thus make more sales...

Just my $0.02

I think the main thing is what we'll do about global warming. We can all argue till we die whether it's us causing it or not. However, if it is us, and we wait to get proof; it would be too late for us to act. If we're wrong, what is the worst thing that can happen? We cause global cooling? Either way, we should decrease our greenhouse gas output.
