Short summary
A step in the annual average CO2 difference between Mauna Loa and the Southern Hemisphere of 0.8 ppm in 2009–2010 has no precedence in 50 years. Variations in interhemispheric exchange coincide with the step, the subsequent 5-year north-south CO2 stability, and historic differences. This behaviour provides a critical test for studies that employ atmospheric transport models to interpret global carbon budgets and inform management of anthropogenic emissions.
A step in the annual average CO2 difference between Mauna Loa and the Southern Hemisphere of 0.8...
