rational behind zero carbon emissions
paul1405,
there can't be a rationale on Zero !

individual: “Govt must act on CC, yeah ? Sounds great, but what is it they demand Govt do ?
Let's hear it !”

Based on what the “experts” have screeched about to date, one would expect greater efforts to reduce emissions, and probably the imposition of carbon taxes. There would be more substitution of baseload coal-fired power by more (probably subsidised) intermittent renewables, resulting in:
. forcing up electricity prices;
. increasing the frequency of power blackouts;
. increasing Australian industry cost disadvantage;
. forcing more Australian business entities to close down or move offshore;
. declining employment opportunities, and higher job losses;
. deterrence of new investment;
. suppressed or negative economic growth;
. increased adverse health effects of residents no longer able to afford electricity;
. increased destruction of bird-life by wind turbines;
. greater visual pollution from wind turbines.

But what benefits should be expected from taking more climate change action?

Based on what the past 30 years of climate change action overseas and in Australia have yielded, none!

Raycom,

You ask what government can do.

Soot 'Beam up me Scotty' Morrison, our new climate change warrior, is working on it.

Though the only action he can take is to prevent Australia being the number one victim of global warming is to get the big emitters of greenhouse gases to reduce their emissions.

In fact his political career now depends on it.

Based on what the “experts” have screeched about to date, one would expect greater efforts to reduce emissions,
Raycom,
Without the willingness of the Paul1405's, SteeleRedux's, Mr Opinion's et al no Govt is able to reduce emissions because it's the consumers such as these three et al whose demands for commodities drive the industries to satisfy the demand !

individual,

Don't worry, Soot 'Beam up me Scotty' Morrison has it all under control.

Won't be long before he has all those big greenhouse gas emitters eating coal out of his hand.

Paul, please humour us and tell us how it is to be done.
I for one have not seen an explanation.
