claim: when 3 per cent of total annual global emissions of carbon dioxide are from humans and Australia prod­uces 1.3 per cent of this 3 per cent, then no amount of emissions reductio­n here will have any effect on global climate.
evidence: In the modern era, emissions to the atmosphere from volcanoes are approximately 0.645 billion tonnes of CO 2 per year, whereas humans contribute 29 billion tonnes of CO 2 each year.
