Think we'll need to take the indirect approach - ie. solve the problems that feed into global warming. The problem is unfortunately too abstract and has too much diffusion of responsibility, tragedy of the commons, etc. in favor of it getting worse not to attack its precursors first.

Disagree quite strongly, both think that it's pretty much impossible to do anything about most of the problems and that it's entirely practical to stop global warming before it happens. Carbon emissions are falling and there is an international consensus that they need to fall further. As the cost of technologies continues to fall, it will only become easier and will even start happening by default. It will make more sense for developing countries to invest in solar power and storage than to invest in fossil fuel technologies. And even with the American federal government abdicating its responsibilities and letting the rest of the world down, America is still doing its part along with every other country.

Yeah there are definitely concrete things we can all do to mitigate climate change--we addressed the hole in the ozone layer by banning certain chemicals, and it's recovering now.

I'd agree that we're already doing that.

When I said that I'm thinking of some of the high yield indirect activities like promoting family planning and education in third world countries, economic and educational improvement mean better choices available, fewer children, many places like Brazil where the rainforest gets cleared by subsistence farming starts happening much less when poverty is reduced, etc.. I think the UN had a list of something like 200 issues to tackle and some people did cost/benefit analysis to see which ones yielded the highest benefit for dollar spent and they found some strong leaders (a few which I just mentioned) that came in at the top.

I do think EV's will help out a lot. When you have a whole bunch of EV's on the road yielding zero emissions themselves but which may pull power from a coal plant it's much easier to scrub the pollution at the coal plant than to ensure that every car on the road has a fully intact exhaust system and that the catalytic converters are doing everything they need to or even if they are we're multiplying small output by hundreds of millions which increased output at the local coal power plant to cover charging the EV's won't come near the level of pollution of combustion engines.

Global warming is, in its collection, a big problem but it's a big problem that emerges from a confluence of small problems. The more of those small problems we tackle the less likely it will be that we need to do anything really draconian in one area or another. In the later case we can't go to legislative extremes because we can see when things get really uncomfortable for the average citizen you have sweeping left and right-wing populism which is likely to reverse such legislation or worse. Also add to that last piece - extremes would take legislative will across the globe which is something we've seen reliably fail.

Based on what I have heard recently, the entire Australian economic balance will essentially be destroyed if coal exports are banned altogether...
It is our second biggest export...
Economic suicide, and yet the skool cids who went on strike from skool recently, don't have a clue... :roll:

BTW...
I couldn't read the OP's graphic even with max magnification...
And there wasn't a link...
Am I missing something?

Edit:
Never mind...
I worked it out... :wink:

Hmmm...
It is a pretty graphic but how do we know it's authenticity without context/links?
I am not disbelieving its validity as such, but I would be a rather silly person to accept it out of hand, wouldn't I? :wink:

Yeah, it didn't fit WP image formatting all that well.

sorry.
here's the link:

also: this is not a scientific dataset. it's a webcomic. by a former nasa guy, and it's very nerdy, but still - it's an infographic, not raw data. It does fit with what I've learned from lectures from universities I found online - but it's the scaling of the whole thing and the jokes that make it interesting.

anyway.
@Pepe: you say, the operation (decreasing co2) might be succesful, but the patient (Australian economy) might end up dead.
I think the striking school kids don't think it's worth having a successful operation (the Australian economy), and the patient (human civilization) dead.
I mean... they are skipping school because they are assuming that education for a job in a world that won't exist by the time they graduate is not worth the effort.

I think it would be difficult to find a more clear-cut case of a biased source!

The Australian coal industry has bigger problems than "what if the government banned exports?" - it should be more worried about "what if nobody wanted our crappy coal any more?"

Australia has some of the greatest solar resources in the world. With a little investment, you could be the world leaders in marine energy. I think you actually lead on energy storage technology? But coal is now more expensive than solar and wind power, and much more damaging for the environment. In a few years, you won't be able to sell it.

Firstly, rightly or wrongly, I believe the: "Destruction of the world" scenario within 12 years time is laughable...
Base On what I heard recently, Al Gore predicted that would have happened already...
I'm still here...
Are ewes? :mrgreen:

Secondly: Australia's entire CO2 contribution is negligible in the scheme of things...
Our entire emissions are about the same as *additional* Chinese emissions each year...
The head climate scientist of Oz admitted that if we shut down Oz completely "today", there would be virtually no benefit in regards to reducing global warming...

The kids are kids...
They have been shown to have limited scope, and obviously, have been brainwashed by their parents or skool teachers or unwanted (and technically illegal) infiltration by outside fanatical groups...

And consider the Dunning–Kruger effect...

Any mature person can validate this observation...
Well, I can, about myself, at least... :mrgreen:

Australia’s coal export values have hit a new peak of $56.5 billion in 2017, according to the latest trade data from the Australian Bureau of Statistics (ABS). https://www.australianmining.com.au/new ... d-in-2017/

Coal is Australia’s most valuable export in 2018
Coal will replace iron ore as Australia’s most valuable export this financial year as supply concerns lead to a steep price rise for the core commodity. https://www.smh.com.au/business/the-eco ... 50nd4.html

Fact check: Does Australia export cleaner coal than many other countries?
Prime Minister Malcolm Turnbull told journalists he did not agree with a moratorium on Australian coal.
He said that if Australia stopped exporting coal, the countries that buy it would import it from somewhere else.
"So if Australia were to stop all of its coal exports, it would not affect - it would not reduce global emissions one iota," Mr Turnbull said.
https://www.abc.net.au/news/2015-11-27/ ... er/6952190

The claim: Prime Minister Malcolm Turnbull says Australia exports "by and large" cleaner coal than other countries.
The verdict: Experts say Australian export coal is of a higher quality on average compared with other countries, meaning less is needed to generate the same amount of energy. This leads to lower carbon emissions by weight compared with coal from other countries. Mr Turnbull's claim checks out.
"In fact, arguably it would increase them because our coal, by and large, is cleaner than the coal in many other countries."
https://www.abc.net.au/news/2015-11-27/ ... er/6952190


Mr Turnbull claimed that Australia's coal, "by and large", was cleaner than the coal in many other countries.
His claim was made in the context of what would happen to global emissions if Australia stopped exporting coal.

Experts told Fact Check that Australia's coal is on average high quality as a result of its low moisture and ash content, and high carbon content, compared with other countries, particularly Indonesia, the largest coal exporter in the world.
As a consequence, less Australian coal is needed to generate the same amount of energy, leading to lower carbon emissions by weight compared with coal from other countries.

Mr Turnbull's claim checks out. https://www.abc.net.au/news/2015-11-27/ ... er/6952190
