Thanks but I'd rather breath the street air than the stuff coming out of a exhaust tube.

Thanks for the numbers Steve, it's interesting to see it.

Well, these numbers may look very small, 1% at the scale of the earth is enormous.
And the natural production of greenhouse gaz is absorbed by the plants and oceans, whereas the human CO2 is added to the atmosphere... that is a huge difference.

One should not forget that life is very rare. It only developped on earth because of the delicate and subtle balance found on the earth. It seems that 1% additionnal greenhouse gaz, coupled with deforestation, is enough to disturb this balance. It may not provoked the global warming, but surely accelerated it.

Of course your particular car is not responsible for the global warming.
But like Sartre said, one people can make things change. if you decide to act in an eco-friendly way, you'll induce other people to do so, and gradually it will have an influence. if you buy your car with pollution in mind, and that a lot of people do so, it will make the carmakers hurry up the production of green cars. If you lessen your electricity consumption and buy "green" appareils, it will make the industrials recognize the need for greener goods...


Wikipedia has some graphs figuring the spectacular increase of greenhouse gas since the Industrial Era, but they wouldn't work here, so if you're interested, - ONLY REGISTERED AND ACTIVATED USERS CAN SEE ALL LINKS - CLICK HERE TO REGISTER


wikipedia says:
Since the beginning of the Industrial Revolution, the concentrations of many of the greenhouse gases have increased. The concentration of CO2 has increased by about 100 ppm (i.e., from 280 ppm to 380 ppm). The first 50 ppm increase took place in about 200 years, from the start of the Industrial Revolution to around 1973; the next 50 ppm increase took place in about 33 years, from 1973 to 2006.[26]. Many observations are available online in a variety of Atmospheric Chemistry Observational Databases. The greenhouse gases with the largest radiative forcing are:


(Source: IPCC radiative forcing report 1994 updated (to 1998) by IPCC TAR table 6.1 [6][7]).

Also found this, not sure about the source though:
Human CO2 is a tiny % of CO2 emissions

What the science says...

The carbon cycle

Human CO2 emissions

Carbon isotopes - the human "fingerprint"

The ocean's diminishing ability to absorb CO2



Anyway...it's better to prevent such troubles than to cure them, so even if it's very complex and not as simple as some says, I will try to make some efforts.

Good info

The earth has experienced higher Co2 levels in its past that were not man made., ice core samples prove this. The earth warms up then cools down.

In about the 15th century when greenland was discovered it was called Greenland because.......it was green, and warm and not the ice shelf it is today. The earth was warm then it cooled a little and 1600s in london Queen elizabeth the 1st held ice parties on the river Thames now its getting warmer again. Its a cycle the earth gets warmer then it cools.

If we have a year when the earths volcanoes erupt more ( at the moment 40% of all co2 comes from volcanoes) then it puts the humans pollution in the shade.

I believe its more to do with the suns influence on us more than our pollution.

It funny how the figures also state that since 1997 the earths mean temp HAS NOT GONE UP but has fallen 0.5c and all of a sudden its not global warming but climate change.....

HELLO the climate changes it always has and it always will!!!! what a brilliant TAX

You're right Steve, the earth just happens to be in a warming period. This is normal.

However, the trouble is that... this warming happens way too fast. And this is because of us. It is not the warming that we are producing, but we are making it happen too fast. The earth and life will not be able to adapt itself to this warming because it is fast and "sudden".

Of course volcanos, cows, dinosaurs emits more CO2 than humans. But like the article says, this CO2 is balanced by oceans and trees.

We are emitting CO2 that can't be absorbed by the earth, so it goes into the atmosphere and strenghten the greenhouse effect.And the deforestation is lessening the earth's absorption capacity. Then the oceans seems to be full so won't absorb as much CO2... So more into the atmosphere, so more greenhouse effect...

The quantity of CO2 in the atmosphere has risen shockingly since the Industrial Era.

We are destroying the balance, with our 1% and deforestation.

The global warming is too fast, and thus will go even faster, and we don't know how it could end. So, we'd better try to be more cautious by now...

I dont believe that the earth is perfectly balanced at all. The earths corrects the balance over many years, if loads of volcanoes erupted today and if humans were not on the planet the amount od co2 would not be soaked up by the trees/ oceans. It would take a long time for it to right itself.

My argument is that the earths gets in and out of these periods all the time and i dont belive we are having the effect the governments are leading us to belive.

Do you honestly think that if the Governments of the world thought we were heading for impending doom that they would do i little bit more than just tax us???????????? come on......

All of the sudies showing co2 rising have been paid for somewhere by people/companies/governments who want us to believe this IS happening to make us pay more money so thay can make more money/tax us more



there are intances in the earths history that co2 has risen faster than it has today and the world has warmed quicker than it has toady, unless every person on the planet cuts back it wont happen.

My last example is lets say we ie the developed world......USA Europe etc lower our emmissions China/india etc are making more and it isnt reduced anyway im starting to bore myself here

Lets just agree to disagree


Now then what else can we debate
