Global Warming

Freezer said:
There's a kid's news program on here called Newsround at about 5.30 in the arvos - only goes for about 10 minutes (just before Neighbours :hihi). I saw it the other day showing the icepacks cracking and melting at the poles and saying how it was all due to the human effect on climate change. There was no mention of the fact this warming and cooling of the atmoshere has been going on for millions of years producing similar results to what we're seeing currently.

Don't get me wrong, I'm all for less emissions, recycling, saving the forests etc, but I wish these programs would put forward a balanced view of the facts, rather than just this scare-mongering propaganda that we as humans are completely to blame for this phase of the atmospheric cycle.
correct wieght freeza,that they think that they have to rain their THEORIES down on us like it is the new bible gives me the shivering quits.... and especially the messiah al gore the facist rich prick whose houses use more power than most 3rd world countries who travels the world in 1st class emitting a massive amount of carbon while he preaches to the peasants......go figure?
 
The warming and cooling has never followed patterns like this before. That's why scientists are so unnerved.

But is it completely the fault of humans, or could it just be that Mother Nature is changing? No doubt we are contributing but I just don't think our contribution is the sole, or major, factor in what's currently happening. I have seen/heard plenty of conflicting evidence regarding what is causing climate change - enough to make me think someone like Al Gore has multiple agendas behind his ramblings.

Nobel Peace Prize - give me a break.

No, i think you should go first, SS. You raised it afterall.
oh come on 6y the "MAN" :hihi always leads...... you first my time plenty friend

Wouldn't it be a little too remarkable that the sudden deviation from the normal pattern of temperatures and carbon levels came at a time when mankind is releasing massive amounts of heat trapping gases into the atmosphere (an event that has never happened in the Earth's history) and it wasn't the cause?
 
i just thought if you claimed that he was a 'facist' that you'd be able to back it up. Seems like you can't.

Didn't this happen during the industrial revolution though, without the corresponding rise in temps?

(This is a genuine question - not a smartarse quip! ;))
 
Not really Freezer. We're pumping out far more now than ever before and we pump out more year after year.

But then you can find things like this that to a lay man like myself, suggest climate change is very much a cyclic thing, as are carbon dioxide emissions. It's all rather confusing and is the reason why people such as Gore, who are so adamant that we are the root cause, aren't necessarily 100% correct.

Accompanying blurb:

"These graphs show temperatures and CO2 recordings from ice cores taken in Antarctica going back 400000 years. The time scale is reversed with the current time on the left. Here we can see the effect of several glaciations and the brief periods of warming in between. When there are high concentrations of CO2 in the atmosphere it causes higher world temperatures. When the CO2 levels are low then the temperatures are low. This shows that CO2 is the decisive working greenhouse gas affecting earth's climate. More alarmingly, the current level of CO2 is substantially higher than in any time during the last 400000 years and the level is rising at an accelerating rate.

Note: Although a relationship between CO2 and temperature exist and the fact that CO2 is a greenhouse gas, the conclusion that the different levels of CO2 are the driving force of temperature changes is actually not supported from these graphs."

FASCIST..an extreme ,IDIOTIC loyalty to a state ,which may or may not exist.fascism is an authoritarian POLITICAL IDEOLGY that considers the need of the state and seeks to forge a type of usally based on religous or racial attributes.................... pretty self explaintory i would of thought...i could also say facist hypercrite or remind you of the many catholic preists that *smile* little boys whilist denouncing the same monsters from high on their pedestals......

With graphs like that I'm surprised we are all still alive. The climate doesn;t seem to have changed in correlation to that graph at all.
 
I think we would be incredibly unwise to ignore the scientific consensus. Its a very complex area, ocean currents, continental icesheet melts, sun fluctuations and volcanic activity are all possible causes - but given the large % increase in CO2 in the atmosphere and observations of melting glaciers and warmer mean temps - a causal relationship seems likely.

The real problem is one of political will. No country wants to be disadvantaged economically while other countries are non-compliant. My own personal feeling is one in all in with measures to combat the problem, regardless of a countries level of development.

I'm probably missing something obvious here, but if the graph shows a correlation, why do they not support the theory that carbon affects surface temperatures?

There's a lot of events happening recently (like 10000 year old ice caps melting) that seem pretty good proof of the earth getting hotter.

That's part of my point Disco. Those graphs were from NASA and to the naked eye show a strong correlation between CO2 and temperature. Then they say:

It seems even the scientists are confused. I know I am.

The scientists, I think, are acknowledging the fact that just because the graphs LOOK as though there may be a causal relationship, this may not in fact be the case.

For example the handspan of a child may appear correlated to running speed, however it would be ridiculous to postulate a CAUSAL relationship. The apparent relationship is due to another factor (age/growth) that is related to both.

Exactly. So if NASA won't say there's definitely a causal relationship, why should I believe Al Gore?
