But in ref to the CO2 levels; Could it possibly be due to the fact that we have denuded the planet of forests and covered what remained with tar and concrete and metal. This would have the effect of increasing the carbon dioxide levels because the plant life that previously occupied the cleared areas is no longer there to use the CO2 and so the naturally created carbon dioxide from volcanic and other natural earth chemical reactions will increase many times over and the more we expand across the planet the less CO2 will be taken up and on and on it goes. It is just a thought and not based on so called scientific investigation n stuff. So feel free ta shoot the notion down in flames with proven facts.

Approx half the mass/weight of a tree is carbon dioxide that has been removed from the atmosphere and retained in the tree/plant roots and leaves etc as carbon. Does this carbon get converted to CO2 when the tree burns or is it released into the air as carbon dust that eventually falls back to earth??
When a tree burns there is a hell of a lot of carbon ash left behind on the ground and hanging in the air, so clearly not all of the carbon gets changed to Carbon dioxide.

Loss of vegetation and land clearing does add C02 to the atmosphere. But the major contribution to the rise of atmospheric C02 is the burning of fossil fuels.Fossil fuels and volcanic C02 each have a characteristic isotopic signature (C13/C12). The isotopic signature of atmospheric C02 is moving year by year closer to that of fossils fuels which shows that they are major contributor to the rise of atmospheric C02 which has an atmospheric resident time of tens of decades compared to water vapor (a powerful greenhouse gas which reinforces the C02 greenhouse effect) which has a very short atmospheric residence time of maybe a few days.

Sounds plausible to me.

So if the C14/C13 is moving closer to that of fossil fuels, what would be causing this? Could this be as I said, due to the land clearing and increasing spread of cities across the surface of the earth causing even more natural CO2 to remain in the atmosphere.
At what altitude are the CO2 levels measured.
Countries like Australia with population 23,000,000 produce very little CO2 compared to China India/Middle East and the USA that have populations in the hundreds of millions. These countries use enormous quantities of fossil fuels.
Why would the Middle East or China cut back on coal and oil? The Middle East survives on oil sales.
In Australia we have huge uranium deposits that can be used to produce and supply very very clean energy yet we do not utilise it because the Greens think the nuclear power stations would go into meltdown and wipe us all out by atomic radiation poisoning. There are nuclear power stations throughout most of Europe China and Japan and Russia and England that have been in use for more that 60 years.. The world is still here.

My apologies
I have made a typo in my earlier post.The isotopic ratio should read C13/C12! Plants and animals prefer to utilize C12 over C13 and hence oil, gas,coal,wood are all enriched somewhat with C12.Thus when burnt their C02 is enriched with C12 compared to C02 from geological sources like volcanoes, oceanic out gassing hot springs etc. C02 is measured globally at a number of locations and altitudes.In Australia the monitoring station is at Cape Grim in Tas.

Well Curtin radio has got it wrong! No climate scientist or the IPCC are making such a claim!What the IPCC said was that severe weather events would become more common by 2050!!
Give me time and i will find the relevant info from the IPCC's special report and post them here.

You take as long as you like to come up with another of your theories.
Are we to believe you have it right, I didn't hear the news, and the Curtin University reporters information was wrong?
OK, won't lose any sleep over it here.

*** Tell me I'm wrong with this fact;
East of Geraldton near Moonyoonooka fossils found prove that this land was covered by ocean millions of years ago.
The city of Perth stretching to the Darling Range was once under the ocean.***
You'll never prove me wrong on that one!!!!

Its not a theory the IPCC in their special report on the Oceans and the Cryosphere did not state that the sea level would rise by 10m by 2050 nor did they make this claim in their media release.
This is the relevant portion of their media release.
More frequent extreme sea level events
"Sea level rise will increase the frequency of extreme sea level events, which occur for example during high tides and intense storms. Indications are that with any degree of additional warming, events that occurred once per century in the past will occur every year by mid-century in many regions, increasing risks for many low-lying coastal cities and small islands"

Yes the ocean did at some time cover a large portion of Australia plus also in more recent times there are aboriginal stories of ice sheets over what is now the NT.
There is also evidence that the planet has shifted on its axis long ago and stars shown on ancient Inca star charts are no longer visible from that latitude. This little happening has altered sea levels all around the world enormously not to mention the earth quakes, volcanic eruptions and tsunamis, changes to icecap distribution,fires tornadoes huricanes and mass extinctions that would have accompanied this significant axis of spin shift.
I do not recall where I obtained that information from but it has been buried in my grey matter for many years.
There is mention in the bible of the sun standing still in the sky for a day pale

I guess they kept tabs on the time with sundials and water clocks? I think maybe someone might have had a dose of magic mushrooms that day? Laughing

coz it is something that would not go unnoticed by other people around the world aye?.....Och aye! Tis a strange world we live in master jack.

While this excellent topic has re-invigorated discussion on this forum, and it is also very interesting to see the contribution from members that have been around for many years, I must admit that I am becoming switched off by the so called facts that have been added by a recent member who appears to not have any interest in the intended purpose of this forum and is just using it to sprout unsubstantiated techo talk.
Planetcare, if you wish to conribute to the Gold Detecting and Prospecting topics, please do so, else I suggest that you take the other contributions elsewhere.

Ladies/Gents, this topic has has now been spoken of in full, all that's been said about climate change has been said. Better weather conditions are on the horizon. Time to get back into the hunt for that "Golden Ointment" This topic is now closed.
