Wow...this thread could turn into some serious debate about greenhouse gas, global warming and suchlike !!!
I chuck my 2 cents worth here....
Way back in the Cretaceous Period, when dinosaurs ruled, the CO2 levels were 20 to 30 times higher than today's levels.........the result being that the world flourished as never before, because high CO2 is a paradise for plants, hence the world was covered in vegetation from pole to pole. From whence we get all our coal, oil and gas that we use today.
Sea levels were 80 meters higher than now because there was no ice.
The Planet has had many episodes of high CO2 and will continue to get them for millenia to come. The REAL problem is that high CO2 and thus high temperatures raise sea levels....and because we choose to build Cities close to the Ocean, it is very inconvenient for humans to have their Cities flooded !!!!
But Mother Nature dont give a damm.......it will all go on , with or without us !!
CO2 emmission control is a myth, it is simply an untapped, infinite resource for all Governments to generate a Fresh, New stream of Taxation, all done with bleeding heart statements about Global Warming so all us suckers will cry into our beer and be happy that we are once again the mugs who pay for all these grandiose and pointless, futile efforts to control things that are bigger than Politicians.
Sooner or later, Mother Nature, Destiny, or as some would have it...God...will deal with this pestilence on the Planet called humans and will redres the balance. Maybe it will be AIDs, Bird Flu, Swine Flu, Ebola or some such awful pestilence....but one day we will cop it !!!
I can never understand the sheer arrogance of humanity that has to believe that nothing else on this Planet is as important as people !!!! Who, incidentally are the biggest problem on the Planet.

I will pose another question about Global Warming/emmissions....
If plants absorb CO2 and give off Oxygen as part of the process of photosynthesis...by which we get oxygen to breathe......
And if we are chopping down forests at an alarming rate, and clearing land for housing and industry at an even bigger rate, thus removing much of the vegetation that provides our oxygen
If then at the same time we are breeding more and more people and more and more animals to feed these people...thus producing more and more organisms who need oxygen.
And if we are producing more and more CO2 as a result of these processess..........from less and less plants able to provide oxygen
Why then aren't the oxygen levels on the planet falling ?In fact, oxygen levels are slowly rising !!!
Queer aint it
