The science is getting a bit confused a little while back, I tried to clarify it

So, Tom are you talking about the stockpile of old newspapers on the energy
embodied in the newspapers?
The calculation between the volume of a single newspaper and the volume of Uluru
should not be that difficult - though I am unsure of the point of the comparison.
We could also consider the greenhouse gases that the newspapers would produce as
they broke down. Bear in mind that newspaper is generally recycled paper.
We could also add the cost of delivering the newspaper to your door, generally
by car in the 'burbs...
