Some years from January to January there may be a rise of 0 ppmv (ie no change), some years up to 3 ppmv.If those changes were due to man-made CO2 then we should see more of those rapid increases in recent times as man-made emissions increased faster.But the globe has been warming during that period (in fact since the depths of the Little Ice Age around 1680), so warmer conditions could be the reason that CO2 has been rising.Salby does not dispute that some of the rise in CO2 levels is due to man-made emissions, but found that temperature alone explains about 80% of the variation in CO2 levels.Instead the sources appear to be in places like the Amazon Basin, southeast Asia, and tropical Africa — not so much the places with large human emissions of CO2!But CO2 is a well mixed gas so it’s not possible to definitively sort out the sources or sinks with CO2 measurements around the globe. Instead the way to unravel the puzzle is to look at the one long recording we have (at Mauna Loa, in Hawaii, going back to 1959) and graph the changes in CO2 and in C13 from year to year.Judging by the speech Murry Salby gave at the Sydney Institute, there’s a blockbuster paper coming soon.Listen to the speech: “Global Emission of Carbon Dioxide: The Contribution from Natural Sources” Professor Murry Salby is Chair of Climate Science at Macquarie University.

It has passed peer review, and sounds like it has been a long time coming.The largest increases year-to-year occurred when the world warmed fastest due to El Nino conditions.The smallest increases correlated with volcanoes which pump dust up into the atmosphere and keep the world cooler for a while.Plants are ‘deficient’ in C13, and so, then, ought to be our fossil fuel derived CO2. We are 5.5 and plants are putting 121.6 into the air each year (not counting ocean plants).The implication is that since coal and oil were from plants, that “plant signature” means “human via fossil fuels”. There is a lot of carbon slopping back and forth between sinks and sources.
