Story summary

Australia’s tropical forests are emitting more carbon dioxide than they absorb, reversing their role as carbon sinks.
Hannah Carle of Western Sydney University led research showing extreme weather, rising temperatures, and cyclone activity drive higher tree mortality.
Between 1971 and 2019, carbon storage shifted from net gain to net loss in these forests.
The findings indicate current models overestimate offset potential, underscoring the need for stronger carbon management.
