You have been asked this about 5 times now Greggery.
We are still waiting Greggery.
And tell me again,
why exactly do I need to answer your question?
You claim to be a sceptic.
You claim to be open minded.
You claim to be well read on this subject
You asked for evidence to support my statement that the majority of the observed rise in atmospheric CO2 concentration is from anthropogenic sources. I showed your a published scientific paper that reported on the measurement of the change in C12 ratio of atmospheric CO2.
You were shown evidence. You were shown credible evidence.
If you think that the evidence you were shown was not credible - perhaps you may like to explain why it was not credible.
How long are you going to keep running away Greggery?
You are not a sceptic. You are a denier.
You are not open minded. You refuse to even try to understand the evidence that has been presented to you.
You are not well read on this subject. You are ignorant.
If you had any idea what you were talking about - you would explain to us why the evidence you have been shown in response yuo your query was neither credible or convincing. You would explain to us why you think that measuring the C12/C13 ratio of atmospheric carbon is not a credible way of determining the sources of that atmospheric carbon. You might even propose an alternate explanation as to why there has been an observed increase in the concentration of atmospheric CO2 if it is not from the burning of fossil fuels and other anthropogenic activities.
But you can't, can you Greggery. You just close your eyes and your ears and go back to reading WUWT.
Who do you think you are fooling Greggery?
