Climate Science for DummiesMalcolm and others have a refrain of "show me the evidence", so I thought it was worth setting this out as clearly as possible. If you want more detail, the Garnaut Report chapters 3-5 are a good summary. What is undisputed1. The so-called greenhouse gases (GHGs)* do what they say on the tin. Specifically, they absorb certain wavelengths of infrared radiation. The sun pours in 342 watts per square metre of energy into the planet every day, and some of it is not reradiated back into space because of greenhouse gases. If they didn't do that at all, it would be too cold for human or much other life. There is no qualified scientist on the planet that disputes this basic science.
2. There is more greenhouse gas in the atmosphere than at any time over the last at least tens of thousands of years, and the amount has been climbing steadily year on year at an accelerating rate for at least the last fifty years. These are direct observations, for recent years by direct measurement, and for the history from concentrations of CO2 in deep ice cores. 3. The great majority of the growth in atmospheric CO2 is anthropogenic – ie we did it, by burning fossil fuels and clearing land and spreading fertiliser and raising cows (cow and sheep farts contribute 11% of all Australia's GHG emissions, and there wouldn't be any of them here at all if humans weren't raising them). The more powerful greenhouse gases don't appear in nature at all, so we can't blame anyone or anything else for them (unless you have evidence that aliens have been secretly importing them from off-planet). What is only disputed by the willfully blind or deranged1. The planet has been getting hotter in the last 50 years, and for the last 30 years has been hotter than ever recorded. There are no remaining unexplained anomalies in the observational series whatsoever: regional and other differences eg in the high atmosphere are all accounted for. I have heard people claim that the world has cooled / stopped warming since 1990: since 12 of the last 13 years are the highest on record, they have to resort to three-card tricks or falsified data to attempt to justify this ludicrous claim. It is true that some regions around the north Atlantic were as warm in 1250 as they were in 1975, but a) the sort of fluctuations in the Gulf Stream that caused that are included in the mainstream models, b) this wasn't true of most of the rest of the world, and c) anyway, all but four of the years since 1980 have been warmer than that. There is, of course, no direct observational record of either the medieval anomalies or the regionality. Both the claims and the refutation rely on anecdotal and other contemporary observations without instruments, and on indirect observations such as tree-rings. Insofar as anecdotes and tree rings count for anything, they support the submission that the world wasn't generally warmer / colder at those times as much as or more than they support the claim that it was. We can't claim that European monk's accounts are more reliable than Indian or Chinese ones, only note that they record different trends. NB: if you were relying on The Great Global Warming Swindle for a different view on how warm it was in 1250, note that the UK broadcasting regulator has castigated the program's makers for altering their graphs to mislead viewers (eg, on that one, by re-labelling 1975 as "Now"). 2. Getting hotter will be a Bad Thing. Thousands upon thousands of detailed studies have been done over the last twenty years on the impacts of warming. They have indeed identified a few impacts that are positive, but these are enormously outweighed by the negative impacts on everything from crop yields to disease ranges. Even the crop yield gains from CO2 fertilisation in some crops disappear at warming of more than two degrees, and are overwhelmed by the rainfall changes above that. What can be debated1. How much warming is due to GHGs? The mainstream science says that doubling GHG concentrations raises the temperature by 2 to 6°C. The sceptics say 1) something else is causing the warming, eg solar cycles, volcanism, or whatever, and therefore 2) since the GHGs definitely do cause warming, they're contributing less than the mainstream models show, and so we don't have to worry yet about further increases in GHGs, because they won't warm us as much as is feared. 2. er – that's it. Since GHGs do cause warming (basic physics) and are increasing (undisputed observations), any other touted cause boils down to that argument. Note also that alongside the sceptics there are at least as many scientists (eg James Hansen) who think that the models underestimate the GHG effects, and therefore we need more drastic action than the mainstream models suggest. The problem with all the other alternative explanations for warming is that they either don't change at the right times in the right direction to explain the temperature record, or that there is no observable mechanism for them to put enough energy in. For example, the total energy expended/burnt by all human activities to date is simply insufficient to have had any direct impact on warming: we may be able to keep our cities a degree or so warmer at ground level on a cold day, but in the great energy budget scheme of things it just doesn’t count. Solar variations obviously do have impact –all of this energy came from the sun originally – but they vary at different times and different directions than the temperature record does. Huge amounts of effort have been put into understanding this, and the chances that there is some missing high-energy source we don't know about and can't detect are very small indeed. Finding one that stands up to scrutiny would be worth huge amounts in support from people like Exxon, so there is plenty of incentive for scientists to publish if they found one. And equal bunce for peer reviewers who got that paper through to publication. And the count of peer-reviewed papers in scientific journals supporting the sceptics' position: none, nada, zero. What if it's a conspiracy?What if all these thousands of scientists working in all the countries of the world have a secret conspiracy to defraud us all? Well, if just one of them decamped from the conspiracy with evidence of it, they'd be living in luxury on the rewards from those interested in keeping the gases flowing. What are the chances that a) it exists, and b) none of them have gone public? I leave that exercise to the reader. What if warming is mostly caused by arbitrarily advanced alien space bats?If there is some real as-yet-unidentified cause of warming that we don't recognise, or if thousands of scientists have uniformly and systematically got their model coefficients wrong, and some combination of other factors is causing warming, then what should we do that's different to what is currently planned? Well, this runs into the undisputed territory again. GHGs do cause additional warming, and warming is a Bad Thing. So, if the warming to date is caused by something else, and that is going to carry on having this effect (if we don't know what it is, it would be imprudent to assume anything else), then we should take action to reduce as far as possible our efforts to add to that warming. So, if the mainstream science is wrong, we need to reduce GHG emissions even more than is currently planned. Simple really. Now let's get on with it. [ category: ]

Living standards
Scott, living standards are falling you say. Well I for one think they should. If people stopped borrowing on credit cards to buy mountains of useless junk then they would be able to meet their mortgage repayments and fuel bills. Frankly I have little sympathy for people who scream poor when one look inside their house and how they live will tell you why they find themselves in trouble when interest rates and fuel bills start to rise.
The belt is so loose it can stand a hell of a lot of tightening.
All that discretionary spending on junk, running up a mountains of debt - the chickens had to come home to roost eventually. Totally unsustainable and destroying the planet in the process.
A couple of weeks on pea soup might help people sort out their priorities.
Thank you Bill...
For the good belly laugh. I needed that just right now as I settle in for a long night's work.
Cheers
population growth and ecological rationality
Anyone who has been around ecological politics sees the re-emergence of the population issue on a routine basis. It is a no brainer. There are simply too many people at present for all of those currently drawing breath to enjoy the benefits of industrialised modernity in a global ecological system that is closed.
At a global level there are too many North Americans. They use too much non-renewable energy and consume far too much in the way of resources. Their lifestyles are way too ecologically expensive.
At a national level the management classes occupy a similar space - too expensive, don't contribute enough even in the way of taxes let alone socially beneficial production.
Of course, if you hold that there simply are too many people regardless of the distribution of resources then the way is open to you to do the decent thing and reduce the world's population by one person.
Anthony,
Who do you want me to kill?
Useless breathers
Anthony Nolan: "Full employment in the earth repair industry would be sustainable growth."
Population growth where people don't consume any resources, grow any crops or take up any space that might be used by anyone or anything else would be sustainable growth.
Scott: In agreement for a change and I'd better start counting posts.
Australia has taken a huge step forward.
Jeffrey Sachs in the SMH says that we are making the right decision by taking steps to limit our GHG emissions by introducing the Carbon Reduction Trading Scheme. He points to the opportunities, Australia will be able to take hold of by being in the forefront of the changing global economy.
We can lead the change and we will bring the rest of the world with us. This is not gloom and doom, it is the future. A wonderful future of economic wealth and a green planet. The sooner we get with it the better.
'The Great Global Warming Swindle' Swindle
Those inclined for whatever reason to read the writings of the resident global warming sceptics of the House of Fairfax: Miranda Devine [1] and Michael Duffy [2] will notice that in the case of Devine, her head-down charge continues, while Duffy ('Forced to join the hollow dance') is engaged in some tricky footwork: that is, liable to finish up with one in each camp.
He now points out that the Rudd government's greenhouse gas emissions policy, insofar as it can be ascertained) is likely to be ineffective. This is the same member of the Commentariat who heartily endorsed The Great Global Warming Swindle before it was aired on ABC TV, but got roasted alive in the panel discussion which followed the broadcast of that ironically titled piece of televisual garbage.
Many are rightly sceptical in the true tradition of science, but are not waiting around for 100% proof to emerge that the burning of fossil fuels is responsible both for the global warming as measured to date, and for the tangible climate changes we have seen. The greatest uncertainty is now with the proposition that such burning is not damaging the planet's climate balance.
I wait for both of the abovementioned luminaries to admit that CO2 emissions could possibly be warming the planet. I am confident that I will have to wait longer for them to say something should be done about it.
I am extremely confident that I will have to wait longest of all in the case of Miranda Devine. Perhaps until all the Jews have become Presbyterians.
Ford loses $9 billion in 3 months.
The high price of oil is shifting us to more fuel efficient cars. The sooner we put a price on all GHG emissions the sooner we will see our emissions fall.
Isn't the market great?
sustainable growth is possible
It depends on how and what you define as growth. Full employment is growth. Full employment in the earth repair industry would be sustainable growth. Tree planting, reforestation, cleaning the waterways. Limitless possibilities. Good clean outdoor work. Compost. Wonderful stuff as Peter Cundall says. Should be spread on everything really. Needs armies of people to do it. Maybe turn the central west of NSW into what they once were (wetlands) again.
Sustainable industrial/capitalist growth or (ahem) industrial/socialist growth gave usLake Baikal and the Great Lakes of the USA . Phew. No thanks.
Winners & Losers - Joy & Sorrow
Billaburra old mate, I agree. The Buddhist in me looks at our land and sees change and suffering. I've journeyed out there and would argue that the climate has done less to decimate a land, that has provided life to abundant variety of fauna and flora for yonks, than the interference of you know who over such a brief period of time.
Human beings have really stuffed this country and it was because of our arrogance and ignorance, not the climate.
The climate will always be changing and with change there will be always winners and losers. Some will suffer, others will exploit the opportunities.
The deserts of North Africa were once fertile forests, carbon collectors and supporters of animal life. That all ended up beneath the earth and eventually turned into oil which we all now use.
I have no doubt human beings are destroying this planet, but I still feel that carbon has less to do with it than the manner in which we have exploited and poisoned our environment.
This planet will be around for a long time yet; maybe humans and many other life forms wont be. If we end up topping ourselves I don't think Mother Earth would miss us anyway.
I was a dinosaur once and now I'm a bird with beautiful wings; should the dinosaur in me feel sorrow, or should the albatross in me feel joy?
Wise old albatross.
Mehtinks that you are a wise old albatross, Justin.
At least you would not shit in YOUR own nest.
Be joyful that you are a bird with beautiful wings.
Soaring high in the sky, and enjoying the feeling of the bracing wind upon your brow...
Rejoice and be glad,
It ain't all that bad...

Real Gone Kid
Ha! Mitchell's a real gone kid, Malcolm.

Come to think of it, I'm a "real gone kid," too!

Really Gone Kid
Weird.
Well that's a relief
Many years ago, Malcolm, I read about ET experiences. They go back to Elizabethan times at least. H.G. Wells notwithstanding and apart from the odd kidnap or two (not to mention the loss of valuable livestock), they appear to be benign.
I can vouch for that: I was kidnapped and raped by five gorgeous aliens (well raped is maybe putting too fine a point on it). The sixth one missed out - I was stuffed.
Quo vadis?
Assuming they were females, Scott Dunmore, did you manage to get their telephone numbers?
So it's come to this
John Pratt, I've now read your linked article. Purely out of interest why don't you replace the words "climate change" with the word "Iran"? I think It'll show this guy's argument in a whole different light.
Actually, the appeals to emotion, and repressed guilt, are rhetorical devices, best used as the final hook by the hucksters wearing overly large Rolex watches, otherwise known as televangelists.
Get on board, please!
Justin Obodie: "But not in the last 10 years apparently."
Empiricist!
Very high confidence that climate change is a real threat.
Kenneth Davidson in this morning's Age.
The planet is faced with the threat of catastrophe. In Australia the debate still goes on with the government saying we should do the bare minimum by 2010 and the opposition saying we should put it off until 2012. How will history judge these leaders? Will they be the Neville Chamberlains of our generation?
Global temperature for June 2008 0.9F above mean.
For those who still believe the Earth is cooling, don't let the truth get in the way of your fantasy.
Sustainable population increase
John Pratt's post concerning Dr Bob Birrell, who I know very little of personally, apparently concerns the relationship between "growth", rapid immigration and population increase, and the environment.
Is Birrell connected with Sustainable Population Australia or any other dry-green groups?
Am in dispute with an amigo over whether or not population increase is sustainable, given the mess the country seems to have put into following the ascendancy of "growth" at any cost economics. Would rather see something serious (finally) done to fix environmental and social and education infrastructures first, rather than blundering into yet more population increase on the verge of a recession and before sustainability has been assessed, beyond its significance to "developers", Macbanks, construction companies and bent politicians.
Reason I write this is, got into strife some years ago when I mistook the refugee crisis for an underhand neo-lib attempt at increased migration by stealth, to keep unemployment high and wages and conditions down for the majority. My argument then, as now, is get the preconditions fixed first, then worry about bringing appropriate numbers out after things are set up to accommodate them.
I believe the savage demolition of Australian environment by greedy, moronic "developers", has compromised this country's capacity for radical population growth in the future.
Which is not to say that we could not fulfil our humanitarian obligations to the third world poor in a more efficient way, actually, by radically upping targeted, genuine aid for places like Timor L'Este andNew Guinea , say (rather than just aid as just means for exploitation of poor countries).
If some folk thus think me a "racist", because I think the life boat shouldn't be overloaded to the point of capsizing, then so be it.
Just a wee problem
David Roffey: "And, if you aren't too hot on truth, you can say that this shows a cooling trend, even though you're still talking about most of the hottest years on record, and the rolling average goes steadily up from 1998 on."
It's, a fair question, though, one would think. I mean, manmade emissions certainly have grown since 1998. If one is to believe the warmists this should result in continual rising temperatures. It clearly hasn't.
People are asking Australians to accept a diminished lifestyle. The least they could do is point out the truth of what this will mean for most of them. They could also point out the truth that Australia's efforts may result in nil achievement globally - or even make things worse - and that's certainly not going to save the Australian landscape if indeed warmists are to be believed.
If the climate change people were for real or at least want doubts taken away, they should concentrate on cutting "pollution" - something only a complete cretin could disagree with. My contention is they don't do this because it changes the debate away from enforced government stand-over tactics, and away from enforced poverty. Wealthier nations demand higher standards of lifestyle - this means less pollution - no rich person ever wants to live in a toxic swamp - and let's face it, they don't.
A society can only be "rich" with economic growth - it cannot come about any other way - that's why the need for "global apocalyptic doom" exists. The spin in fact is no different to that put into use by multitudes of religious cults over thousands of years.
PS. If Mr Duncan is planning a political campaign he is on the right track understanding that people's monetary living conditions don't need to be destroyed to have a cleaner country. In fact their monetary living conditions can (and should) be improved and the country still be cleaner - people in fact will demand that very thing. The tide is turning, and it will only turn quicker, as more of this insane scheme moves into common understanding.
Slightly cooler warming
1998 was the second warmest year on record. Amazingly some sceptics have discovered the fact, apparently hidden by some scientists, that there is only one year warmer than the second-warmest, and all the other years are less warm than the second-warmest, even though they are the fourth and fifth-warmest, and so on. And, if you aren't too hot on truth, you can say that this shows a cooling trend, even though you're still talking about most of the hottest years on record, and the rolling average goes steadily up from 1998 on. Utter bollocks, but it's good enough to fool Michael Duffy, as almost anything from that side is. Here's the full graph for Australia (the global one is similar but slightly less variable from year to year). You can see how really cool the last bit is for yourself.
And the good Dr Gray. From where I stand it's no' a good look to be ageist, but it is a fascinating observation to make that almost all of the scientists who are pinups on the sceptic side haven't actually worked on the science since 1990 (Dr Gray is 86), which makes their last formal involvement in studying this stuff being well before almost all of the current scientific work was done. It wasn't like that in my day, I can tell you. And another multi-layered conspiracy that tens of thousands are keeping secret from you, by gum. Next, how scientists are covering up the evidence on leprechauns (have they looked under every leaf at the bottom of my garden? No, they haven't, and until they do, I'm not going to accept that they might not be hiding under the other one, it;s just a cover-up).
introducing some key ideas...
... in relation to global ecology. Neither term needs explanation as they are in and of themselves readily comprehensible:
A prudential attitude to global ecology is required. It implies a "what if" attitude towards potential negative consequences. If we err on the side of ecological caution that means some economic/material losses for current and future generations in the interests of sustaining the ecological conditions of existence for a multitude of life forms, not just humans.
Intergenerational equity means not consuming non-renewable resources or "natural" resources at such a rate that either the former are too rapidly exhausted or that the latter are so diminished as to be incapable of self re-generation. By the former I mean energy resources and the latter I mean forests, rivers, seas and soils and so on.
These are key principles. Acceptance of these key principles is a reasonable acid test for deciding whether one is dealing with an adult or deciding whether one is dealing with someone who is so pathologically focussed on their own immediate needs and gratifications that they are clearly little more advanced than an infant. A big, needy, resource consuming infant. There are a lot of 'em around.
That is what capitalism runs on, of course. People whose sense of self is so feeble, so entirely pathetic that they cannot even imagine substituting consumer gratification for something more substantial like the sense of having generously gone without so that other species, unseen people and future generations might have a viable planet.
It is bigger than all of us
"The planet has been getting hotter in the last 50 years"
But not in the last 10 years apparently.
"There is more greenhouse gas in the atmosphere than at any time over the last at least tens of thousands of years"
According to a Dr Vincent Grey:
"This statement is a lie. 90,000 measurements published in peer-reviewed journals since 1850, some by Nobel Prize-winners, have been suppressed by the IPCC because they do not agree with this statement. (Beck 2007). Stability of carbon dioxide in ice cores thousands of years old is questionable. (Jaworowski 2007). Recent measurements of carbon dioxide are confined only to exceptional circumstances over the ocean, and do not include measurements over land. (Manning et al 1994).
Dr Grey does not appear all that convinced regarding the global warming thing.
Methinks the only way we will truly understand the complexities of weather and climate is to get the O'Mighty Mama (OMM or God in human terms ) to tell us how it works.
We aint trying to understand the internal combustion engine here - we are trying to make sense of something that is way beyond the comprehension (at this point in time) of humans, especially the punters.
We collect data, write code, create models and those models make projections (people are paid to do so and like most of us want to continue to get paid).
And that's what we get - erections, er, projections , and very expensive ones at that.
At this point in time I doubt whether any of these models can cope with reality. I was reading something recently that stated water vapour was only just recently included in the sums. I wouldn't have a clue how it all works and wonder who really does.
It is still debatable if human activity has in fact affected the climate (and if so to what degree) and we are still trying to understand how the relationship between carbon, climate, sun spots, panda bears and the butterfly works; relationships that do not exist in solitude but in chaotic synergy with all that exists in the heavens and earth.
When OMM tells me humans have fucked the climate I'll believe it, unchallenged; until then it will take some very clever dude who can explain to me in words of one syllable, or show me how it all works.
And by the time I'll be sleeping with the fishies.
One thing for sure, we may be able to change our carbon toe print but we will never be able to stop climate change. OMM will make sure of that.
The way things work
Justin, you don't need to know how a fish works to know a healthy one from a dying one, do you? I imagine an albatross can tell the difference from a mile away.
If you ever decide to fly inland for a little reconnoitre, you will see a dying land. Seagulls do that, though fewer these days than used to. Talk to them, and let them tell you about it, because when they do you will likely decide not to fly inland. They will tell you about little lakes where water birds teemed not long ago; dry and silent now. They will tell you about puzzled pelicans staring down at brown ponds surrounded by miles of dry cracked mud, seeing no fish but dead or dying ones, and wondering how they are going to fuel up so that they can get back to the sea, where they belong.
The seagulls will tell you about swimming holes along rivers where people used to picnic and leave scraps for them to eat. No picnicking there any more; and no scraps — just signs telling the people to keep away from the few pools of stagnant water left there, because they are contaminated by blue-green algae.
It won't drive us kookaburras away: we gave up kingfishing long ago, and even learned how to live without a drink of water. We are beginning to miss the sounds of the other birds, though. Many of them can sing much better than we ever could. And when the people move away we will miss them too, because we have always liked to live near people. Very amusing, those people.
We don't know how things work. We don't even care. It makes no difference to us who is responsible; all we can do is see what is happening to our world. If we could think at all we would probably think those scientists and commentators should stop arguing, drag themselves away from their graphs and models and go take a look at what is happening on the ground. Get out more, is what they need to do. Let the deniers deny what they can see.
The cave only has so much room
Scott Dunmore: "Paul, I don't doubt your intelligence but when are you going to start thinking outside of capitalist dogma?"
Well, it's been around a long time. Probably since the one caveman decided to swap a shell for a stick - rather than just beat the other guy to death.
Well, no.
Economic growth will end one day; the same as the earth will eventually end (you fellas have a specific date?). So what? Your point is?
If people wish to live their lives on the edge of apocolyptic doom, that's their choice - and there's thousands of cult religions to meet their needs (including socialist environmentalism). The only time such things concern me is when they try and force the "Kool-Aid" onto me and mine. I doubt I'm Robinson Crusoe in those feelings.
If people wish a life of poverty best talk to someone else. It's something I've thankfully avoided and something I'm keen on others avoiding (only if they want to of course).
The successful plan should be self evident
A good start:
1. Understand Australia: Australia is a vast and isolated land with a small population. It cannot be compared to Germany or any other European nation for that matter. Doing so makes as much sense as comparing an apple to an orange. One would think this to be self evident.
2. Understand the Australian economy: It's plainly obvious many don't or seemingly are content deluding themselves about it.
3. Understand why economic growth is a major goal: Without economic growth Australia simply cannot enjoy many of the things it now takes for granted - even expects as a natural right. Take a look at third world nations and the old communist bloc to understand where sustained periods of negative growth ultimately ends.
4. What Australia wishes to achieve: Apart from apocalyptic visions (most extremely tenuous), nobody has yet given an insight into what it'll cost, and what it's meant to achieve. Mr Rudd won't even give a target figure on emissions that he can judged on - and he can't guarantee that China simply won't take up the slack or increase it. It's actually fairly pathetic.
Plan:
Australia already has at its disposal all it needs to implement change without either hurting economic growth or Australian lifestyle. Australia has a massive surplus - and there simply isn't any excuse to have such a surplus. By using incentives through the tax system, people will change their behaviour where they can. People will not be able to change behaviour, even with punishment, if it's impossible. I think China, India and the United States have made this point clear.
Simply punishing people is lazy socialist dogma - which throughout history has ended in abject failure - no doubt this plan will also fail. The carrot will always be more effective than the stick. Who wants to be a millionaire isn't who wants to lose a million dollars!
Words
"Well, it's been around a long time."
No Paul, it hasn't. I was specifically refering to dogma. Capitalism of course has been around a long time the same as socialism, but both are just words for the way things work. I, as a small business man, am every bit as much a capitalist as yourself, fighting my competition and trying to create an extra market share and you are just as socialistic in lifestyle as me. We have no choice. The way we think about things is different but that's all and that is still only a question of degree.
"Simply punishing people is lazy socialist dogma - which throughout history has ended in abject failure ."
Well I can't think of a tenet of socialism that recommends punishing people, and I agree that carbon trading schemes are just plain bloody daft, as I've said before.
You advocate economic growth which must result in increased consumption and at the same time agree that it cannot be endless. I think you have a dilemma here: just where does the transition kick in?
Global warming is still the least of our problems, permanent or temporary, it's a straw man.
Spliting my sides
Thank you Bill.
Paul, I don't doubt your intelligence but when are you going to start thinking outside of capitalist dogma? because that's all it is, the same as socialism.
Your point three; think about it. Can economic growth possibly be endless?
Ever increasing consumption of resources.
I agree with you about taxing carbon, daft as a brush, but don't confuse Ruddism with socialism. It's nothing of the sort.
Past the tipping point my friend; as I said, party while you can, let the devil take the hindmost and then some.
Advice from one who knows
Never splite your sides, Scott. Too painful.
Clear messages are strong medicine for denialists
Well done, David. The kinds of simple but powerful arguments you make here should be included in any Federal government campaign explaining action on climate change and the emissions trading scheme.
Fiona: Welcome to Webdiary, Darren.
Prattling on; lost in the roffey - good walk ruined
Yes, thank you both for that irrelevance. What is your solution?
The point is, what do you propose as a plan to redress the mess (if there is one)? What do you do with the displaced coalminers?
A couple of weeks ago we had dinner with old friends of mine and my parents. The friends have two delighttul and very intelligent daughters. One has just started reading medicine at Newcastle and the other is in year 12 at a selective High School. When I broached the obvious (that the only way Australia could have any effective role in reducing emissions was to phase out coal exports) she immediately made the intelligent point that such a policy would destroy the economy of the Hunter Valley.
The only positive I can see coming out of the destruction of the economy generally is that I might be freed from reading John Pratt's posts.
Now, if either of you has a practical and practicable solution to the "problem" could we hear it articulated please? And don't give me this trading or capping crap. Tell me the effect it has on everyday Australians.
Shared irrelevance
Intelligence must lie in the eye of the beholder. Only one without much of his own to draw on would see much intelligence reflected in an objection to a plan intended to save the world from disaster on the grounds that it would destroy the economy of the Hunter Valley. Then again, the objection comes from a year 12 student in high school, albeit a selective one.
Malcolm, you said earlier that you have "put out bold, difficult policies that are designed to replace coal-based power generation with solar." It doesn't take much thought to see the impracticality inherent in any such policy, of course; but were it possible, how do you reconcile that with your revelation that the preservation of the Hunter Valley economy is paramount?
Of course this whole discussion is nonsense anyway. People seem to want to talk about the effects of global warming on Australia. They even want to talk about the effects it will have on the Australian economy, of all things; when what is under threat is the world as an inhabitable planet. Thought — the only human activity that doesn't produce greenhouse gasses — is avoided like the plague. We even find references to cow and sheep farts: things that have never existed. They would rather live in their own little dream world than face up to reality.
Try to turn people's attention away from futile tinkering and towards the all too obvious fact that we have gone way past the point of no return and should be looking at ways whereby we might ease our species' adaptation to an altered planet, and they scuttle off to start another thread about stupid, futile tinkering.
Coalmining for the future
Coal is the prime fossil fuel that is abundant. It is likely that it will remain a good source of income for the very few Australians who work in it (30,635 of them according to the Australian Coal Association). Given that the price has risen 100% or so in the last year without demand lessening, I don't guess that the added cost from carbon permits is going to make much difference to those numbers in the working life of those currently employed there.
Which brings us to the difference between us on this. YOU want to prescriptively close down their business and replace it with solar. I (and the government) just want to price in the environmental impact and let the millions of people and businesses affected by that price find their own best solutions for reducing the carbon content of what they do. They'll make better decisions than I (or a civil servant) will.
Do nothing will not work.
Malcolm, humans have always adapted to change. We will adapt to the changes brought on by reducing our GHG emissions.
You ask about displaced coal miners. They will go the same way as horsemen, telegraph operators, coachmen, bullock team drivers, icemen, night cart men and thousands of other occupations that were necessary in the 1800's but not so necessary today.
You needn't worry: there will always be a need for lawyers.
Successful nations in the next few decades will be the ones that adapt first and sell the emerging technologies to the world, technologies such as solar, wave, and geothermal where Australia has an abundance of resources.
Malcolm, Garnaut has laid out a plan, a way forward. What is your plan? A do nothing approach puts us all at risk.
Dummies
"The only positive I can see coming out of the destruction of the economy generally is that I might be freed from reading John Pratt's posts."
Oh don't say that Malcolm, then I'd also be denied the pleasure of Claude's blogs.
What on earth are you fellows prattling on about? We're stuffed any which way you look at; let's just party while we can.
A price on Carbon pollution is trying to protect our lifestyle.
Malcolm, you say
If we do not reduce emissions we will destroy our lives and livelihoods. For example and a taste of the future see the Murray Darling basin.
Most economists say the sooner we act the cheaper the price of change.
Putting a price on carbon will make all of us look for alternate ways of reducing our emissions. This can be seen already as our driving habits and choice of vehicle has changed due to an increase in the price of fuel.
Why should any business be allowed to pollute the atmosphere at no cost?
Putting a price on carbon will force the polluting industries to reduce their emissions and make industries that do not pollute more competitive. I don't understand how anyone can object to this.
It is not up to the government to come up with a blueprint just putting a price on pollution will bring about change.
Just as we gave up using the streets as a sewer in the middle ages we must now give up using the atmosphere as a sewer.
Consquences of the population rise on our emission targets.
Every new immigrant that calls Australia home will make it harder for us to reach our emission targets. We need to stabilize our population because every new Australia will mean higher fuel and electricity prices due to a higher price for emission permits.
David R: well, I think Dr Birrell has probably been misquoted in the middle para above, since the last para shows he does understand the scheme: clearly if there is a cap, the price will go up faster if population increases - but there is no reason to assume that the cap will inevitably be breached as a result - it won't "fall far short", it will get more expensive, until either the price of energy suppresses demand or the price of finding low-carbon alternatives is cheaper than the permits.
Why don't you just take the money and run?
David Roffey, this really is batshit [and any moderator who wants to edit that out might take note of the fact that I have been described in the article as deranged]. No-one I've seen in this forum has said it would not be a good idea to reduce emissions caused by human activity. What most of us on this side of the fence have said is that it should be done in a way that doesn't destroy our lives or livelihoods.
You still provide no evidence whatsoever that, if warming is occurring, it is solely due to human activity whether human or associated to it via agriculture.
What "GHGs" are you talking about? Water vapour is a GHG. Flatulence likewise. And the more people like you keep spouting, the more water vapour there is in the air.
Now, I'm still agnostic but, unlike you, unlike Rudd, unlike Wong, unlike anyone else I know including the flat-earthers, I have put my money where my mouth is and have put out bold, difficult policies that are designed to replace coal-based power generation with solar. What are you on about lad? Tell us your solution and I don't mean simple chemistry. Give us a plan that solves the whole problem without destroying ordinary working families as they are now called. Green, White, give me a rest - no more paper - let's get a blueprint. And could we pull together for a change? Might just be one huge wank but the sperm have to go somewhere.
David R: answering the easy one, the GHGs specified in Kyoto , and thus the ones controlled by the National Greenhouse and Energy Reporting System and the Carbon Pollution Reduction Scheme, are: carbon dioxide, methane, nitrous oxide, sulphur hexafluoride, hydrofluorocarbons and perfluorocarbons. There is an argument in Garnaut (p59) about also including chlorofluorocarbons and hydrochlorofluorocarbons, but these are covered by the Montreal Protocol, and therefore should be phased out by 2030 anyway. Water vapour and ozone also have greenhouse effects, but aren't primarily human in origin, and water vapour at least is complicated, since much of it forms clouds, which reflect energy from the sun as well as retain heat below them. On the other easy one, where you say "back up your claims", my initial reference to further evidence is as at the top, ie Garnaut, chapter 3 in particular, and then the references on from that (and in the case of references to IPCC IV, the references on from that, too!). PS: I didn't say warming is solely caused by human activity (it isn't), but that the unprecedented growth in GHGs is mostly due to human activity, and that GHG growth is 1) causing a lot of the warming. 2) going to cause a lot more in future.
