Ok so you see that graph a few posts above? Do you see how it has that characteristic sawtooth pattern and where we are now we should be expecting another sharp glaciation (this is called a D-O event)? Well we aren't experiencing any kind of cooling at all, in fact (as you well know) the Earth is warming. Therefore the Earth isn't conforming to this 'cycle that has been going for tens and hundreds of thousand of years' - in fact it is directly contradicting it!

Also actually YES ever since the industrial revolution happened we CAN see a direct impact from humans (260-390ppm CO2 isn't big!?). The reason we haven't seen even more warming than we already have is because the atmosphere is a huge and complex system and it takes decades for effects to be fully experienced.

No I don't think everyone driving Prius' would help because transport emissions are only one small part of global CO2 emissions. But to pay people out who ARE trying to help in some small way while denying the facts is total pig-headedness.

I believe we need to step aside and look at the whole picture here, because there are 2 different things to consider:

a) Global warming: even though we have a tremendous quantity of info regarding our impact on earth, its insignificant to scientifically quantify how bad (or good) is that impact on long terms, because we just know nothing about earth itself, we don't know if temperatures are raising because of us or because the earth itself is getting warmer, and there is no way we could know it.

As it is, this is pointless. We should also consider what happend to the ozones hole hole: it got fixed by itself after we realised the problem and, what is far curious about this is that some believe that being the layer is it was (almost) its increasing the green-house effect

My point is: we don't know. We have no clue how we are affecting earth and, thus, we should stop worrying too much about this effect. What we whould be worried about is having stupid politicians that know nothing about the whole issue and start allowing electrical cars because, you know, they don't generate any pollution yeah, right, they fail to realise you have to plug'em somewhere...and that electricity doesn't come free

b) Pollution in big cities. This point is not questionable nor deniable. Big cities are VERY polluted nowadays, and they are getting even more polluted because they are getting too crowded. This is something that we have all experienced, specially those who live in small areas and seldom go to big cities (I lived in Madrid for a while and funny thing they complain I do smoke...if you feel the same even if you don't while living in those big cities! ).
This we need to regulate. We need to start enforcing more public transport systems, and start limiting vehicles (not that I'd ever drive inside Madrid, its totally nuts) because air pollution is getting even dangerous in some areas.

Funny thing is electrical cars COULD help in this aspect...if it weren't because there are far too many cars in big cities and what needs to be done is to half that number, and start getting more bikes (ala Amsterdam style ), more buses and other stuff.

All in all, its not an easy matter. We need to keep pushing nuclear-based energies because oil prices will keep raising to a point of economy-meltdown, specially with the crisis in those oil-exporter countries...

PS: don't blame the Chinese. They are starting their industrial revolution and, as we did, they are using very dirty fuels, but thats something that will improve upon time. We can't complain about what we did, you know.

You really have no idea what you're talking about. We know A LOT about the Earth and the processes that operate within it - you, however, clearly do not. Please go learn about long term climate trends and how we reconstructed them and then come back.

Surprise! We can measure how much carbon we emit! Shocking ain't it

Yes, we can't even accurately predict weather changes yet we can predict the earth behaviour.

Eh, I'm pretty convinced that global warming is real, but I figure that these things are cyclical. Thousands of years from now we'll probably have another ice age or something.

The point doesn't matter though, of course the climate is changing. The problem is what can we do about it? Even if we were able to shut down everything and completely stop emissions, it wouldn't necessarily reverse the trend.

I say governments should start planning on building housing and researching/bio-engineering and planting drought-resistant crops on ground that is above sea level, and start setting up a plan to gradually retreat from low-lying areas. Sure this event may happen over the course of decades, but it sure beats being unprepared.

Weather is based on incredibly short periods of time, lots of atmospheric volatility and statistical probabilities. Climate is based on long term trends and physics (as well as statistics). They are very different.

Better fuel efficiency doesn't necessarily equate to less CO2 produced, and the closer you get to a perfectly efficient combustion engine, the more CO2 you will produce.

I hate the term, but all one can do is improve the carbon footprint--you can't reduce the amount of CO2 you generate when you make more efficient engines, all you can do is maximize the amount of work they can do.
This is just spin, right? Because if you are suggesting that cars getting 25 mpg produce more CO2 than cars getting 35 mpg you are either a troll or ignorant.
