Australia's Bushfires Have Emitted 250m Tonnes of CO2, Almost Half of Country's Annual Emissions

Bushfires in New South Wales and Queensland have emitted a massive pulse of CO2 into the atmosphere since August that is equivalent to almost half of Australia's annual greenhouse gas emissions, Guardian Australia can reveal. From a report: Analysis by Nasa shows the NSW fires have emitted about 195m tonnes of CO2 since 1 August, with Queensland's fires adding a further 55m tonnes over the same period. In 2018, Australia's entire greenhouse gas footprint was 532m tonnes of carbon dioxide equivalent. 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.
