Australia’s bushfires have emitted 250m tonnes of CO2, almost half of country’s annual emissions
Experts say the pulse of CO2 from this season’s bushfires is significant, because even under normal conditions it could take decades for forest regrowth to reabsorb the emissions.
But scientists have expressed doubt that forests already under drought stress would be able to reabsorb all the emissions back into soils and branches, and said the natural carbon “sinks” of forests could be compromised.
