I remember in the early 1990’s reading in a paper by R M Gifford, that Australian carbon emissions were absorbed by our land area. Added 23 Apr, found my copy and this online reference.
I wonder why Australian Governments would not have taken the view that this natural advantage for Australia could have been a reason for us to ignore the entire IPCC process, leading to Kyoto and beyond, Garnautland – Ruddland wherever our odd leaders take us.
Australia has for centuries borne the extra freight costs due to our location in the Antipodes plus other disadvantages due to our isolation. Unless this early 1990’s data has been proven to be incorrect, I see nothing illogical if our Government was to say, “carbon is not our problem – we already have no net emissions”.
