id be interested in seeing such evidence... what % of co2 is in the atmosphere? and what % of that co2 is man made?

Human-induced increase
The increase in CO2’s share of the atmosphere is mostly due to anthropogenic (man-induced) factors, such as burning fossil fuels, deforestation, and industrial production.
Most anthropogenic CO2 is produced by energy production and transport. Cement production is just one among many chemical processes that release the gas. Rotting organic materials release CO2, and so landfills are big CO2 contributors too.
In total, humans emit around 32 gigatons of carbon dioxide each year. Half of this stays in the atmosphere; the rest is absorbed by oceans and vegetation.
But with sharp increases in man-made CO2 emissions, the natural CO2 cycle has been thrown out of balance: vegetation can no longer transform the same proportion of CO2 into oxygen, and oceans are steadily reaching saturation level.
Theoretically, rising CO2 levels should be compensated for by plants and algae. Up to a certain concentration, more CO2 means more photosynthesis and more growth.
Unfortunately, under hot and dry conditions many plants close their pores to prevent the loss of water and switch to a process called photorespiration during which they consume oxygen and produce carbon dioxide. Only areas with enough precipitation and fertile soils will see increased growth as a result of rising CO2 levels.
The result is an enhanced greenhouse effect and, subsequently, climate change. While CO2 is only responsible for 20 percent of the natural greenhouse effect, it accounts for about 60 percent of the anthropogenic greenhouse effect that is causing the current global warming.
Not such a long read sails.
It's quite easy to calculate.
Pre-industrial levels about 280ppm (0.028%)
Current levels around 390ppm (0.039%)
We have added approx 110ppm (0.011%)
Therefore man made CO2 currently constitutes approx 28% of the atmospheric CO2 and represents an increase of 39% over pre-industrial levels.
Basilio,

Science is irrelevant.
Politics is relevant.

And by the way this stuff about the poor workers of Australia being screwed for $800 a year is again a mischief.
The proposal incorporates a rebate to lower paid workers and social security recipients to mitigate these effects.

Of course if you want create a scene about A BIG NEW TAX you certainly wouldn't want to acknowledge anything that would reduce your thunder.
Thanks to basilio and derty for the informed debate just wish the other side would debate in a similar style.
Droll Wayne, droll. What you seem to be saying is that any facts in this situation are simply irrelevant compared to the machinations of political power. Thats good. We now know that all your convoluted comments trying to disparage global warming were unnecessary because in the end the critical question is not whether there is a problem but how elegantly or forcefully one can deny it.

PS - thanks derty for your information which was given without the silly name calling. Your posts are informative and objective.
The interaction of various forms of life as part of a greater being. In other words, a form of god. It's a nice idea, but where's the proof ?To be brutally honest I have no idea what he's talking about.
It was only a few hundred years ago that the semi-global super organisms were the unelected religious orders that directed their "ants" to work to serve their mysterious gods.I can only assume the "Global Super Organism" is the unelected UN driven one world government that directs us "ants" to work to serve the mysterious Gaia.
ROFLI'm struggling to understand why the the AGW alarmists that frequent this hysteria thread haven't quickly highlighted to us Flannery's Gaia plan for the globe. Surely the alarmists must agree that their main AGW man in Australia (paid by you and me) knows and understands what must be done to "save" the world (or the "ant colony").
Now's the time for the AGW alarmists folks here to step up and bond with Flannery and back his plan for a "global super organism" and a "stronger Gaia", anyone?
To be brutally honest I have no idea what he's talking about. I can only assume the "Global Super Organism" is the unelected UN driven one world government that directs us "ants" to work to serve the mysterious Gaia.
This man has lost it and does not represent me or my beliefs in anyway whatsoever.

Have you come across a book called "Godel, Escher, Bach; An Eternal Golden Braid" by Douglas Hostadter? I'd bet my house Tim Flannery has. Not that he quotes the book or references it directly, but there are loud echoes of Hofstadter in the ant colony as an example of an emergent consciousness and his delight in the way complex systems, not least life itself, have evolved from very simple bases.
Flannery isn't talking about government, neither of one world nor of one nation, nor even of one forum. He's not talking about anything imposed. His discussion of ants doesn't mean that people are mere workers in the service of Gaia (which isn't really mysterious, BTW, and is certainly not a plan). A really simplistic generalisation of what he's saying is that the whole (an ant colony or a human brain) is more than the sum of its parts (the ants or the brain cells).
If this talk gives you the heebies then forget it; it's nothing to do with climate policy. If you're curious about what he's talking about and you don't want to read his book, then have a go at Hofstadter. It's not everybody's cup of tea, but I've been entertained and challenged by it for 30 years and I'd love to pass the fun along http://en.wikipedia.org/wiki/Gödel,_Escher,_Bach.

Good luck. I'm sure by then we will all have our computers turned off because we can't afford the electricity.When the benefit of an ETS is larger than the error in computer generated models, come ask me this question again
