Global warming

[Maxwell the Fool]

I suppose this debate is starting to change my opinion slightly: at least to some aspects of the argument.

Also, the Earth is well within natural trends, and anyone with a mild background in advertising will see in any of Mr. Gore's charts that there are basic perception-altering methods at play here. If you want to dispute that then please do, and link to the chart so that I can expose the lies.

Another variation here. Both are based on data from the Vostok and EPICA ice cores.

 

As you can see, the natural CO₂ maxima over the last 400 000 years was ~300ppm. You can clearly discern the periods of warming from the periods of cooling.

 

Now, according to contemporary CO₂ measurements, current concentrations are well over that, at ~380 ppm ¹²³

 

Well within normal trends?

[Maxwell the Fool]

The level of CO2, the supposed cause, is irrelevant if I reject the theory entirely, which was my opinion at the time of the post. So that's moot.

 

The temperature, on the other hand is, indeed, well within normal levels.

CO2 destroying the ozon layer and letting sun heat leak in is not a theory its a fact, its a theory as long as it aint prooven, you can test that however inside a lab...

however its true that CO2 is not the only cause, there is another gas, whose name i lost, which basicly is available in even bigger quantities and has an even worse effect on the ozon layer

btw, even if you reject the theory its not a moot one, your opinion doesnt necessarily make reality ;)

show us some stuff, references or whatever or explain, blabla, so we can agree or disagree on your "opinion" and discuss why you think so, otherwise its simply of no impotance to the discussion or any discussion in general, bring arguments please :)

 

furthermore, as stated a few pages back by a few people, is it not about a homogenous temperature we talk, its not like "its gets 1°C warmer everywhere", it kinda depends,

due to the destroyed ozon layer more sun gets in = more heat = warmer

due to the increased pollution less sun hits the ground in areas covered by dust clouds = less heat = colder

the result of that are devastating natural disasters in the areas where cold and warm meet aka typhoons, tornados, air currents and so on...

 

however the overall temp rises = rain/snow/floods/changing currents/melting ice

 

if we take that graph as serious we must notice that in opposition to earlier high rise temps our time seems to be kinda stable and didnt peak and then fall down again, it stays at that height which is way above average, this gives the warmth the chance to melt much more ice than usual and change the world in more dramatic ways than a swiftly happening peak

however that graph is in millenias not years or centuries which makes it kinda pointless to look at it alone, we would need to compare it to a sheet which shows the change from pre industrial times to now and another one to pre human times to those when we started mass producing iron (first extreme industry)

Global warming is certainly not fiction, it IS REAL. It's always been real. Do people ever recall that since the recent ice age tempertures have been rising even before humans had a say in it? It's always been like this since an iceage. First there are hot tropics worldwide, then boom it gets colder, and colder, and colder, until an iceage sets in. Then it gradually gets warmer and the cycle repeats. Global warming already exsists and will for as long as the Earth has climates. We don't know why this happens, its just does. Its just that we who are speeding up the process.
