correction: the UNESCO decision was made in 2014! not 3 years ago. They've had 7 years to actually do something and they've done nothing (by all reports).
Instead Ley has been able to wing around the planet and lobby other coal-producing countries to support Aus and over-turn scientific assessment.
Now they have only until 2023 to improve the situation!!!
Will the Morrison Govt decide to do something? I doubt it.
