All good stuff and all too true.

I suggest with incessant demand growth that fossil fuels will run out sooner than we think, thereby largely 'solving' the emissions problem. Australia is now perilously dependent on oil and fuel imports and cannot really afford long term to export gas as LNG from the eastern seaboard. Coal mines are encroaching on prime farmland which seems odd if there is supposed to be plenty of reserves.

In numbers the world is now using 17 terawatts of power comprising say 13 fossil fuelled and 4 non fossil. By mid century due to population growth and a more equitable distribution of consumption we might need say 25 TW = 22 nonfossil + 3 fossil. Nonfossil has to increase more than fivefold in this period. Where will this come from? Hint... ample real world evidence shows not much of it will be wind and solar.

As we desperately burn coal, oil and gas to keep the party going the economic reserves will run out quicker. Perhaps we should worry about that as much as emissions.

The mad population increase pruduces more useless people we feed out of misguided 'compassion'. Stop feeding them.

That`s right, by feeding them and keeping them alive they just breed more
and more
and more
and more
ad infinitum.........

One thing is sure, the Vatican are amazing, behind the scenes lobbyists. They continue to preach the evils of condoms, continue to deny women their right to have their tubes tied in Catholic hospitals, continue to avoid the topic of the real elephant in the room, our explosive global population, all in the name of religion.

Clearly Charles Darwin was correct when he noted that any species will produce far more individuals than can survive and they will keep increasing in numbers until they run out of resources. Then nature will sort it out, in one quick and dramatic thud. So be it, we humans might have evolved to have larger brains, large enough to ensure our own eventual destruction, but not large enough to live sustainably

Only complete dunderheads and moribund morons would envision we could allow the ambient temperatures to rise by a whole 2C!?

And we just don't need to on any grounds, but particularly economic ones!

There are things we can and should do to first quite massively grow the economy, which will among a host of other economic advantages, quite literally suck the climate change gases from our atmosphere, all while providing low cost and endlessly sustainable transport fuels!

More talk won't however, produce a single litre of alternate algae sourced fuel!

Look some algae are up to 60% oil, and virtual child's play to extract! We just talk about saving the Murray, when what actually beckons, is massively improving its wealth creation possibilities! Then only thing we need remove, is the pollies who quite knowingly and deliberately block the way and the endless humbug they use to achieve just that outcome!

Algae absorb 2.5 times their bodyweight in Co2 and given optimum conditions, can double both that bodyweight and absorption capacity/oil production, every 24 hours! EVERY 24 HOURS!

And grown as mop crops, used to sequester coal fired Co2 inside large clear plastic pipes, use just 1-2% of the water, ( effluent is fine or desirable) normally required by traditional irrigation!

All the current yakkity yak blah blah, blah blah is adding, is evermore hot air and bloated oil and coal barons!?

I mean, why do you think there is so little real action occurring on this front?

And more difficult than getting a donkey to gallop and for long enough to win the half mile race!

WE will commit to this or that reduction all while burning and exporting more coal and the climate change gases they produce?

Well we talk a good greenhouse reduction scheme and might even make a few dozen carbon brokers around 140 billions richer every year!?
And all while making black white and farming in Antarctica!
Rhrosty.
