I think that measuring with precision human activity on the climate is something very challenging to do and there’s tremendous disagreement about the degree of impact, so no, I would not agree that it’s a primary contributor to the global warming that we see

Scott Pruitt, Head US Environmental Protection Agency

This is an awesome quote on so many levels.

Like all good quotes, there are truths. Measuring with precision is indeed challenging and the impact of human activity on climate is, without doubt, a source of disagreement.

Then there is an opinion. And you would expect the Head of the EPA to have one, just maybe not one that is opposite to the official view of the agency he leads.

There is also a subtle admission; “the global warming that we see”. Lucky he put that in before some of the biggest storms on record. It’s also an admission somewhat at odds with the rest of the quote. Presumably, you are supposed to look past that inconsistency.

So here is a question to think about.

At what point should a public servant talk up his personal view or that of his immediate political masters over the official policy setting?

Perhaps never.

If public servants simply disregarded the current policy it makes a mockery of the democratic process. Those elected to create policy rely on the system to implement whatever they decide in good faith. And those who elect their representatives expect the system to work too.

This means public servants tasked with designing and delivering workable policy should get on with it even as the politics dances around them. They should stand firm and deliver the flavour of the day.

So to be fair to Mr Pruitt his frame is a new policy and not that of the previous administration.

And then there is the reality.

Here are some Alloporus thoughts on climate change

If this is leadership, heaven help us

Post revisited — the missing link

Can you answer these four easy questions?

Soil carbon — what we think



A sailor in the 1600’s was the last human ever to see a dodo, the bird species from Mauritius that filled the bellies of sailors so effectively they were collected to extinction.

The sailor, a ship’s cook perhaps, was blissfully unaware of what he had just done when he dispatched the last dodo ever seen. He was just doing his job. Indeed it was only with considerable hindsight that we can even imagine who he was even though his name will never be known. At the time nobody knew that the last dodo had just been broiled.

On a hot afternoon in the Zambezi valley in 1988, a male black rhino was so frightened and angry with the sides of a mopane pole boma erected to hold him that he bloodied his nose trying to bash them down. Zimbabwe National Parks officers watched at a safe distance doing their job assisting the capture and removal of the animal to a reserve in South Africa as part of a rescue mission to save his kind.

As I felt the brute force of a metric ton of herbivore trying to escape no thought came to me that this could be it. I didn’t think that a greenhorn academic might be one of the last to see such a magnificent creature born, raised and surviving in the wilderness. After all, it looked like it was, captured and caged as though it were already in a zoo. Except that I could have something in common with the ship’s cook of centuries past. I could be the last human to see the last wild black rhinoceros not otherwise manipulated somehow by a human hand, fence or tranquillizer dart. For history will not record it in any more detail than it could for the dodo.

The thing is that on a planet so dominated by one species there is always going to be the last. And lasts will not herald themselves for our attention. They will happen quietly.

During the time it takes you to travel to work there will be at least one last or even two. The global rate of biodiversity loss is estimated at 0.3% per annum means that species are going extinct all the time. A rainforest tree is felled and the last habitat of an unnamed elaterid beetle is gone. The handful of specimens that lived in it is a last that no human noticed.

Taxonomists are not sure but best estimates are that there are 8.7 million species on Earth although most of them have not been described.

The 0.3% rate of loss comes from global analyses of multiple studies that catalogue habitat loss and degradation across all continents and in estimates of change in the world’s oceans.

At this rate and estimated totals the loss is 72 species per day or 3 per hour or roughly one every 20 minutes.

An obvious reaction to a precession of lasts is to prevent them. It should not have to be this way for surely the rhino could be saved from extinction in the wild and the beetle too. Noble thoughts certainly and those worthy individuals taking on the translocations were an embodiment of them. And for a while, it seemed to work. Black rhino numbers increased steadily through to the millennium and for a while afterwards. Even today during a resurgent poaching crisis in Africa black rhino numbers are increasing at around 3% per annum on a global population of 5,000 individuals.

The beetle was not so fortunate. It did not have a rescue plan and became part of the 0.3% of annual biodiversity loss for that year, unrecorded and unseen.

It is nearly 30 years since that rhino bloodied its nose on the sides of the boma. A lot has gone on. There are over 2 billion more people to feed and economically support. Everywhere there is development or poverty with people running around like ants making either happen.

And all the time there are lasts, most of them unseen.

Post revisited – washing machines

Post revisited – washing machines

What does 2 billion look like?


A two followed by many zeros. It’s big.

This number of standard sized washing machines would fill over 8 million 40 ft shipping containers, roughly equivalent to the total capacity of the global fleet of container ships.

And before the next generation of youngsters get over their binge drinking obsession, there will be 2 billion dishwashers on earth saving teenagers from Cincinnati to Conakry the indignity of doing the washing up.

Quite the improvement considering that running water only entered the majority of homes after the industrial revolution.

Here is what Alloporus said about washing machines in June 2011…

Washing machines

The number of people with the economic ability to purchase a dishwasher will double to more than 2 billion in the next 30-40 years.

Far more will rise above what Swedish statistician Professor Hans Rosling calls the ‘washing line’; an income of US$40 per day, the threshold necessary to own and run a washing machine.

On the one hand this is a worry.

Energy is needed to manufacture and power all these devices as is a water supply to allow them to function. Policy efforts on climate change notwithstanding, the cheapest power still comes from fossil fuels. It is why China is building coal-fired power stations even as they diversify into alternative fuels because they will need the energy to run all the new white goods.

On the other hand, sales of consumer goods will drive economic growth.

This is good news for those who require GDP growth, the enshrined dogma of political success. Nothing will prevent families from buying a washing machine if they can afford it, nor indeed, airplane tickets, dishwashers and cars as their wealth allows.

Couple this inevitable growth in buying power with ever more people and the growth paradigm has never looked better.

Hans Rosling has a very clever way of explaining the population and economic growth combination using Ikea boxes

It is the economic transition that is integral to the population one.

Without economic growth it is harder to see population growth slowing and eventually contracting. Children must consistently outlive their parents for this to happen and that means needs must be met and standards of living must rise.

It seems that we have not fully embraced this reality.

No amount of environmental concern, moral imperative to preserve resources or even fear of environmental collapse is likely to trump the imperative to improve things for our families.

For this is an expression of self-preservation that is hard wired?

There is a reason that Rosling’s Ikea box video has appeared several times on this blog.

It is the best and most accessible explanation of what will happen to the human population of this planet under business as usual. It is also the most likely outcome baring collapse.

But that number, 2,000,000,000 remains hard to fathom.

When the number refers to washing machines an armada like no other is needed to move them to a point of sale. There is such a global fleet and it is ploughing the waves right now heavily laden.

Interesting take on sustainability

Interesting take on sustainability

Our problems go far deeper. We are going to need a rapid and fundamental shift in our values, habits, behaviours, and outlooks.

Marc Hudson

This is a UK academic talking about the empty rhetoric on “sustainability” and reminding us that we’ve known about the problem of using up resources faster than they can be replenished for at least a century, longer if you agree with what was written about the ancient Greeks.

We are no more sustainable than an eBay shopper with a credit card.

As Lilly Allen wrote, “we are weapons of massive consumption” and its not our fault.

We can spruik stewardship of natural resources, modern simplicity, even organic foods but the reality is we are consumers. It is what we do. Not even a circular economy can fix this core trait that is glued to our limbic system with aruldite.

We might need a fundamental shift but no amount of sustainability rhetoric can change the reality that the human condition is to progress, individually and collectively. We all benefit from this for despite global and local problems — and there are many — on average, conditions for the majority are far better today than they have ever been.

So I would argue that sustainability, together with its architects, advocates, and acolytes, are just our conscience talking. Well, whispering actually from the deeper recesses of our reptilian brain stem.

Sustainability, resilience, adaptability and other offerings more at home in the 1960’s are words we know we should hear and act upon but we just cannot make the fundamental shift.

My contention is that we are just not wired for the change that is needed.

Now, if you’ll excuse me, I need to make a sneaky last second bid on one of my watched items.

A post revisited — BMAD

A post revisited — BMAD

Humans are fickle creatures. Yet, as David Hume, the Scottish philosopher, figured out over 250 years ago, we are driven by our passions far more than reason. It can take an unearthly level of persuasion to alter a passionately held view even if there is irrefutable evidence. And many a time the view prevails.

This story about conservation in the face of scientific evidence makes the same point…

It is often said that the end cannot justify the means. This adage comes for the logic that an immoral act is an immoral act irrespective of when it occurs or for what reason.

The other day I witnessed an argument that left me thinking how this is adage is rarely applied.

The discussion began over a conservation problem that is becoming widespread in the eucalyptus forests of eastern Australia. Mature canopy trees are dying from infestations of sap sucking insects that proliferate to reach huge numbers sufficient to defoliate the tree. This explosion of insects and damage to leaves happens where a bird species, the bell miner, is abundant.

Rather than eat the insects, bell miners eat the sugary lurps that the scale insects use to protect themselves – it is a little like harvesting, for the insects regrow the lurp that covers them and the birds come round again.

Bell miners are aggressive birds and chase away other species. This lowers the predation rate on the insects that, over time, means more insects. The insects feed on the leaves that eventually succumb. When the trees lose too many leaves they die back. The process has been given an acronym BMAD; bell miner associated dieback.

Bell miners do well in disturbed forests because they like the dense undergrowth that comes when a forest is altered by fire, logging or other human interference.

Once established the best way to slow the spread of BMAD is active management involving the removal of shrubs. This means suppression through mechanical means, sometimes fire or, more usually, the application of herbicides.

These are drastic interventions of the kind that the conservation movement opposes with religious fervor. Only BMAD is far worse. So even among the ardent conservationists it has been accepted that intervention to remove shrubs is necessary. It is acceptable to manage with interventions of herbicide a habitat that was disturbed.

All good so far. The argument came of over the next issue.

Someone made the comment that ecologically endangered communities could be managed for improvement.

‘No, no, no you cannot do that’ was the indignant cry. ‘You cannot mess with an EEC, you just can’t.’

It was seen as a morally abhorrent suggestion. If something is designated as endangered it is suddenly untouchable.

But why not actively manage? Is it not exactly the same as the intervention proposed to tackle BMAD. In that thorny issue the end justified the means. But the same means cannot be applied to an EEC.

So in the real everyday world we have selective morality.

Let’s just rephrase this outcome.

A Threatened Ecological Community is determined as such by a Scientific Committee that sits in a room in a city and decides a given vegetation type is rare enough and its integrity and longevity threatened enough to meet a set of listing criteria. The committee members review evidence and decide if there is sufficient threat to list the vegetation on a list of habitat types at risk of extinction.

This appraisal confers some protection where the habitat type exists in the landscape. More critically it confers that protected status in the mind of the conservation manager who could contemplate active management for lurp control but not in a habitat that the evidence said was threatened with extinction. That had to be left to be as it is, even if the habitat was degrading and on it’s way out.

No amount of evidence could shift this view. Ironic given the process of listing is supposed to be science based and objective.

Selective morality is not exclusive to environmentalists but they are very good at it. In a way they have to be because there are few options in a world built and driven by profit. They are forced into leaving alone habitat that will degrade in the absence of active management because management is associated with negative outcomes.

Their passion for protection drives them far harder than any amount of reason.

David Hume’s ghost cannot resist a chuckle

Post revisited – Lest we forget

Post revisited – Lest we forget

It is said that old elephants can remember when they were young and the places their parents led them to find water. This memory is triggered in dry times and they lead a new generation to the permanent springs and pools. Makes sense for a long-lived, mobile animal and, indeed, could be a primary benefit of longevity. Evolutionary biologists would add that this also explains why elephant females are the only other mammal we know of where, like humans, older females go through menopause. It helps them live longer.

There are things that humans remember and there are many more that we do not. Our minds are not wired to have all things recorded and catalogued for instant retrieval. They are selective in both what is archived and especially what is remembered and when.

This is true even when the memory is mission critical. How many blokes can instantly recall the birthday of their better halves? It is not how humans do things.

We remember all kinds of things seemingly at random.

No doubt there are triggers for what is recalled so the process has some determinism but there are very few common things that we are all routinely reminded of beyond what it takes to get through life without being arrested.

Then there are the fearsome, nasty and scary things that we block. These rarely make it back into our conscious thoughts unless we are at the therapist.

If we didn’t quite understand something, any memory of it is often vague. Our maths teacher, Mr Dickinson, is remembered for his unfortunate surname and not his explanation of differential calculus.

So even if you read this post from May 2011, you are unlikely to remember it…

Lest we forget

April 25 each year is a public holiday down under and every Australian knows why. It is ANZAC day, a time to remember the brave and courageous soldiers who lost their lives in war. Many thousands attend dawn services across the country come rain or shine.

Australians also know about the Easter and Christmas holidays when many a shrimp finds its way onto a barbie. A fair number also know the religious significance that prompts these days of leisure.

Earth Hour is not a holiday but it is a similar sort of homage, this time to the environment. It began in Australia and is now a global gesture toward restraint in our appetite for energy. There is not a holiday for the environment though. So World Environment Day (5th June) passes without notice; as do the minor events such as World Tree Day (18th September) or World Soils Day (5th December).

There is strong public opinion that the environment is important. Not long after the 2006 release of the documentary movie, The Inconvenient Truth, that went on to make over US$50 million worldwide, action on climate change was palpable. People in Australia took to the streets, “take action,” they said.

Since that time there has been policy paralysis.

Unable to handle lobby group pressure, fearful of what might happen to a carbon intense economy fueled by minerals revenue and coal-fired energy, and an unwillingness to take the real issues to the public, the politicians have achieved nothing.

Initially there was goodwill. Australia signed up to the Kyoto protocol in Bali and there was bi-partisan talk of a market mechanism to price carbon. But the greens said it was not enough and the Carbon Pollution Reduction Scheme was voted down. An odd call that.

The topic was rested.

Then there was failure in Copenhagen, little more in Cancun and deathly quiet over the prospects for Johannesburg. Leverage for the true believers has faded. The vacuum has been filled in part by skeptics, not about the science per se, but about the need to do anything about emissions. And the public seem to have forgotten what all the calls for policy initiatives were about.

We don’t remember that the idea was to become less emission intensive through energy conservation and shifts to alternative energy sources; perhaps even sequester some carbon into the landscape. It has also been convenient to forget that, given the way our economy works, a trading scheme was a handy mechanism to achieve these goals.

We also see to have forgotten that signing up to Kyoto means setting an emission reduction target. As at 2007 emissions were 597 million tCO2e or 77 million tCO2e more than the 5% reduction on 1990 levels. And emissions will, notwithstanding economic slowdowns, rise and grow the actual tonnage of reductions required in the absence of a policy to reverse the trend. Or, of course, Australia could renege on even a modest target.

The noise over a carbon tax is just a smokescreen, a handy way to keep the real policy issues hidden. Perhaps this is because a focused debate, something that talks about what was asked for, would remind us of what we may have forgotten. That a few short years ago most people wanted something done about the challenge of climate change.

Perhaps we should have a climate day, make it a holiday and then we will not forget.

Lest we forget climate day. Well it doesn’t really ring true does it? We can remember and celebrate heroism and sacrifice but not risks to the fabric of our existence.

Alloporus has even slowed on climate related posts and rants. It is not remembered often enough, despite times of deep reflection. Goodness, this year we even forgot to turn the lights out for Earth Hour.

Unfortunately, the earth, its climate and the resources it allows us to consume, is not often in our thoughts. It is slipping away from our culture and we remember less and less of the experiences that it gives us.

In time we will forget about it altogether.

Post revisited — the missing link

Post revisited — the missing link

It used to be said that only death and taxes were certain. All else was a maybe. It seems Australians can now add ‘confused climate policy’ to the list of certainties. Since this post first appeared in August 2011 very little has changed. You could even argue that some of the uncertainty has leaked to other jurisdictions and tweets from the POTUS.

And the message is still missing.

The missing link

Some years ago I wrote an essay entitled ‘What if it’s not emissions’. I was not in denial or even sceptical about climate change, more concerned that we had become fixated with emission reduction as the solution to climate change. So convinced had we become that it was a given that if emissions came down, we would have fixed that awkward problem and all will be well with the world.

My real issue was that we risked putting all our eggs into the emission reduction basket.

After more years of political inaction than seems decent, the Australian government has just released a clean energy future policy on climate change. And, guess what? We still have the same fixation. The proposal is all about emission reduction, initially through a tax on pollution followed by a cap and trade system to make emitting greenhouse gas so expensive that no rational business could afford such behaviour.

It might be about emissions, but the policy formulation sees only a modest reduction target – 5% below 2000 emission levels by 2020. This means in 2020 Australia is pledging to emit 509 million tCO2e in greenhouse gases or 56 million less than it did in 2009.

Only by 2020, even with the proposed intricate emissions reduction policy fully functional, emissions of 679 million tCO2e are predicted.

Actual emissions will increase because the Australian population will grow in numbers at roughly 890 people per day, the economy will grow and so will affluence. Economic growth will require energy to follow the historical trend of a doubling in consumption every 30 years. And although the policy does talk about energy efficiency and alternative sources, the required capacity increase will inevitably be met by traditional means.

Emissions growth will leave a shortfall in the target of 170 million tCO2e or 30% of current emissions. So it would seem that the emissions reduction basket has few eggs.

This again begs the question ‘What if it’s not emissions?

Let us accept what the science tells us and agree that it is emissions that are a significant driver of the current climate warming. What the policy shows is that, rather like American debt ceiling, we cannot quite admit the severity of the problem. And, more importantly, we lack the courage to tackle the problem head on. It is just too hard and too scary.

And this would actually be ok if we hadn’t missed the critical issue in all this.

We have stopped talking about how 7 billion people are going to sustain growth in affluence on a warming planet. We have forgotten about adaptation. Forgotten that we will need to use water wisely, deliver sustainable production on farms, and manage our landscapes when the temperatures change, rains forget to fall, seasonality shifts, severe weather events become more frequent and the sea levels rise.

Less than $1 billion of the $25 billion revenue generated from the carbon tax will go incentive land management through carbon offset projects. They will mostly be Kyoto compliant activities such as permanent tree plantings and flaring methane – just as the international agreement to proceed with a second commitment period of the Kyoto protocol teeters.

There will be money for biodiversity initiatives. Good stuff, but just more of what we have already been doing.

What happened to incentives to revegetate the landscape and put carbon back into the soil? The critical activities that will help us manage that scarce water, produce reliable quantities of food and help save what is left of nature. Missing, presumed dead.

Seems like we should ask again, ‘What if it’s not emissions?

Hidden in deep in the 2017 budget papers from the Australian government is an apparent cut to funding for the National Climate Change Adaptation Centre. This centre is one of the few places in Australia with a focus on adaptation, the thing we have to do if emission reduction fails. Something like Plan B that, given the precariousness of Plan A, should be getting a boost not a cut.

Only this is where we are at just three years out from 2020. Devoid of policy, pushing rubbery emission targets out to the distant future, and cutting funding for Plan B.

For the sake of the grandkids, let’s pray that it is not emissions.
