Heat-stressed Australian forests are thinning fast, producing carbon emissions

Heat-stressed Victorian mountain ash forests are thinning fast, turning from carbon sinks to carbon sources, new research reveals.

Published today in Nature Communications, the research shows forests will lose a quarter of their trees by 2080 due to global warning.

Mountain ash forests are currently one of Earth’s most effective ecosystems for storing carbon – they store more carbon per hectare than the Amazon.

But researchers say these forests will store less carbon in the future as warming causes more trees to die and decompose.
