Methane leaking out of old mining site in Dharawal National Park near Sydney that closed decades ago "..30 years after it was last used. Thermal vision filmed by the Australian Conservation Foundation (ACF) this year, & given to the ABC, shows methane coming from old mine vent shafts..." #AusPol

A gas '80 times more harmful than CO2' is seeping out of a Sydney mine not used in decades

Some 34 years after operations closed at the North Cliff mining site in Dharawal National Park, vision given to the ABC shows methane gas leaking out into the atmosphere.

Great, just great 🙃
