Is savanna in east Australia controlling world carbon uptake?

Published in ERW, 19 Jul 2016

Much of the variability of the global carbon cycle can be attributed to the changing carbon uptake of savanna vegetation in east Australia, according to scientists in Australia and Sweden.

The researchers believe that the country’s disproportionate effect on carbon-cycle variability is due to the amount of moisture available to the semi-arid region – a factor that depends on the El Niño/Southern Oscillation (ENSO).

However, the scientists also found that the extreme carbon uptake seen in Australia in 2011, which contributed significantly to a particularly high global uptake, was less localized to the east. […]
