One lonely molecule…

by Ian Plimmer, Geologist, June 17, 2017


If Australia emits 1.5 per cent of global annual CO2 emissions, 3 per cent of the total annual global emissions are anthropogenic and the atmosphere contains 400 parts per million by volume of CO2, then one molecule in 6.6 million molecules in the atmosphere is CO2 emitted from humans in Australia. This molecule has an atmospheric life of about 7 years before it is removed from the atmosphere by natural sequestration into life and limey sediments.
