    9 September 2014 – The United Nations weather agency today voiced concerns over the surge of carbon dioxide concentration in the atmosphere, which has reached a new record high in 2013, amid worrying sings that oceans and biosphere seem unable to soak up emissions as quickly as they used to.

    According to the World Meteorological Organization (WMO) latest annual Greenhouse Gas Bulletin, the greenhouse gases such as carbon dioxide (CO2), methane and nitrous oxide caused a 34 per cent increase in the global warming in the last 10 years.

    Ahead of a climate summit organized by Secretary-General Ban Ki-moon at UN Headquarters in New York set to take place on 23 September, the WMO urges the international community to take a concentrated action against accelerating and potentially devastating climate change.

    “The Greenhouse Gas Bulletin shows that, far from falling, the concentration of carbon dioxide in the atmosphere actually increased last year at the fastest rate for nearly 30 years. We must reverse this trend by cutting emissions of CO2 and other greenhouse gases across the board,” WMO Secretary-General Michel Jarraud said at a press conference in Geneva today.

    According to the report, in 2013, concentration of CO2 in the atmosphere was 142 per cent of the pre-industrial era (1750), and of methane and nitrous oxide 253 per cent and 121 per cent respectively.

    “We know without any doubt that our climate is changing and our weather is becoming more extreme due to human activities such as the burning of fossil fuels,” added Mr. Jarraud.

    The Bulletin, which focuses on the atmospheric concentrations of greenhouse gases and its impact on the climate, for the first time includes a section on ocean acidification prepared in collaboration with international partners.

    “The inclusion of a section on ocean acidification in this issue of [the Bulletin] is appropriate and needed. It is high time the ocean, as the primary driver of the planet’s climate and attenuator of climate change, becomes a central part of climate change discussions,” said Wendy Watson-Wright, Executive Secretary of the Intergovernmental Oceanographic Commission of UN Educational, Scientific and Cultural Organization.

    The preliminary data in the report indicates that dramatic increase in carbon dioxide levels was possibly related not only to the steadily increasing CO2 emissions but also to reduced CO2 uptake by the earth’s biosphere.

    While there is positive aspect in the fact that the ocean cushions one quarters of CO2 emissions that would otherwise occur in the atmosphere, experts warn about far-reaching repercussion of this process for marine organisms and biodiversity.

    “Carbon dioxide remains in the atmosphere for many hundreds of years and in the ocean for even longer. Past, present and future CO2 emissions will have a cumulative impact on both global warming and ocean acidification. The laws of physics are non-negotiable,” said WMO Chief.

    According to WMO analysis, due to the fastest ever rate of acceleration, the current level of ocean acidification appears unprecedented, at least over the last 300 million years.

    “If global warming is not a strong enough reason to cut CO2 emissions, ocean acidification should be, since its effects are already being felt and will increase for many decades to come. I echo WMO Secretary General Jarraud’s concern – we are running out of time,” said Ms. Watson-Wright.

    Stressing that the Greenhouse Gas Bulletin provides a scientific base for decision-making, the WMO Secretary-General has called for immediate international action to prevent further deterioration of the environmental situation.

    “We have the knowledge and we have the tools for action to try to keep temperature increases within 2°C to give our planet a chance and to give our children and grandchildren a future. Pleading ignorance can no longer be an excuse for not acting,” concluded Mr. Jarraud.

  • Long-term threat to Moreton Bay

    Long-term threat to Moreton Bay

    The RAMSAR listed wetlands of Moreton Bay are under threat from more developments than the proposed 3,600 home development at Toondah Harbour, according to media platform eFlux.

    Collier International’s vision of the future for Southern Moreton Bay

    Already approved developments include the $1billion 65,000 home Pacific-City at Norwell Valley and a new freeway, linking that city to the Gold Coast and Brisbane. So far there are no plans for public transport. Moreton Bay Council announced in February plans to more than double its economy in two decades by encouraging agribusiness, construction and tourism.

    The Bay is home to more than 50,000 waterbirds, including one percent of the world’s migratory species.

    The Southern Moreton Bay Islands 2030 Community Plan, now a decade old, does not mention the major development of infrastructure required for Pacific City and its proposed satellites.

    Moreton Bay Shire Council plans to expand the region’s economy from $17billion to $40billion by encouraging development in agribusiness, construction and tourism.

  • UK Architects want buildings to last

    The Architect’s Climate Action Network in the UK has called for legislation to regulate embodied emissions of new buildings using ‘whole life-cycle assessment’. The network writes that “Being ‘green’ when occupied is poor compensation for construction using masses of concrete, steel and glass.” About 70% of the total emissions of a modern buildings comes from the concrete, steel and other building materials. The architects network points out that vast emission savings are available through simply legislating to encourage reuse of existing buildings and design for longevity. Most modern buildings are designed to last for only 25 to 50 years.

    Sources:

    In his weekly environment roundup on Pearls and Irritations on May 9th, Peter Sainsbury wrote, “A couple of months ago I highlighted the carbon emissions associated with the materials needed to keep high-rise buildings standing – turned out that over their entire life-cycle, four-storey courtyard buildings are the most energy efficient and environmentally sustainable form of housing. So claims of ‘carbon neutrality’ for skyscrapers that are covered in green walls, have triple glazed windows and use 100% renewable energy need to be viewed with some scepticism. Being ‘green’ when occupied is poor compensation for construction that involved masses of concrete, steel and glass, all of which contain lots of ‘embodied carbon emissions’ – the emissions associated with the extraction, manufacture, transport, installation, maintenance, demolition and disposal of materials. Over the life-cycles of today’s typical offices, warehouses and homes, the embodied emissions constitute around 70% of total emissions.

    “Most building regulations ignore the embodied carbon and yet significant carbon reductions can be made relatively cheaply by following five simple strategies:

    • Build less: reuse existing buildings
    • Build smart: use low carbon materials
    • Build efficiently: use fewer resources and waste less
    • Build circular: design for reuse and recycle
    • Build durable: design for longevity.

    “The UK’s Architects Climate Action Network is calling for legislation to regulate embodied emissions including requirements to assess, report and reduce embodied carbon using ‘whole life-cycle assessment’; limits on embodied carbon limits in building materials and building types; and Environmental Product Declarations to be made freely available on a national product database. For nations and companies that are serious about tackling climate change, the time for smoke and mirrors is long past. It’s no use a building being carbon neutral in its daily operations if its construction involved materials containing lots of embodied carbon. Commissioners, designers, builders and occupiers of buildings need to lift their game.”

  • Breaking the media model

    Breaking the media model

    The demise of regional newspapers in Australia is the latest reminder that the business model of media has been broken by the Internet. Funneling tax-payer dollars from the ABC into regional print may not be the most intelligent response, however.

    Rupert gets a Papal Knighthood
    In 1998 Rupert Murdoch received a Papal Knighthood

    There is a widely held and often expressed assumption that independent journalism has flourished under and been supported by “the rivers of gold” that represented classified advertising in particular but advertising in general. It follows that the transition of those funding dollars away from traditional media to facebook, Apple, Google, Amazon et al has created a vacuum once occupied by the fourth estate, that governments now attempt to address.

    This narrative has led to a number of government interventions, including the attempted regulation of online communication systems, the calling of executives before committees of elected officials, and threats to frame legislation that curtails special privileges enjoyed by tech companies or reinforces the advantages given to traditional media companies.

    That narrative is overlaid by privacy concerns, the veracity of news and the use of mass media by foreign actors to manipulate the democratic process. All these factors combine to create a wicked problem of the first order, that will only be resolved over coming decades as we shape a new communications system and political process that can operate within it.

    There are a number of important elements missing from this narrative, and their absence makes it all the more difficult to understand what is happening. Adding in these elements, adds to the complexity of the picture but, at the same time, makes it easier to understand.

    Advertising and Journalism: an arranged marriage

    Implicit in this narrative is the assumption that a separation of powers in traditional media allowed journalism to flourish independently from the influence of powerful advertisers.

    Of course, that separation of powers did exist in the great media properties of our time and launched brilliant examples of holding truth to power and fine traditions such as the protection of sources and other forms of immunity that allowed journalists into war zones under similar conditions we have come to expect for medical services.

    It was never universal, however, and it only existed at all through the impassioned efforts of its greatest defenders.

    In general, media owners have wielded great power through their ownership of communication networks and have used that power in the same way that bankers have, to control and manipulate the polity for their own ends. Rupert Murdoch quoted mentor Lord Beaverbrook as “selling to the masses to eat with the kings” and since backing Fraser in 1975 has consistently taken his role as king-maker very seriously. He recently re-organised News Limited specifically to separate the cash-cows from the influence-wielding consumers of capital. He is not pretending any more that his media ownership is a business concern.

    The first newssheets carried only advertisements and gradually the printers realised that they could use the “eyeballs” they had garnered to influence people and thus the editor was born. The relationship between advertising and journalism is entirely arbitrary and opportunistic with journalism the dependent parasite feeding on the rivers of gold. The television headlines, the day’s talking points and the front page of the newspaper have always been out of the hands of the editorial department and in the hands of the media proprietor regardless of the popular perception to the contrary.

    The significance of this is to recognise that it is up to the journalism community to follow the money and find the way to use the evolving platform to promote truth, rather than to preserve some blessed alliance that is under threat.

    Readers Digest, trade press and big data

    The manipulation of popular sentiment through public ritual is as old as religion and has experienced various historical climaxes in Olympic and Roman Games, public executions, football and mass rallies famously choreographed by twentieth century dictators.

    The far more subtle collection and collation of personal data by secret police or other informer networks has an equally ancient and unvenerable history. The techniques were refined by the Catholic Church and the Communist Party of the Soviet Union.

    In a parallel but similar universe, the combination of the printing press, postal system and global capitalism allowed the Readers Digest to create a user-pays, infotainment network in which the customer, come content consumer, pays to build an increasingly accurate profile of their preferences so they can be drip-fed content-on-demand for a fee. The combination of base subscriptions supplemented with one-off fees for special products was well established by the sixties and fed into a burgeoning mail-order network that sold a significant portion of the retail trade operating in that decade.

    As a young Packer editor in the 1990s, I was flown to New York and Boston to study the techniques of database mining which was then responsible for a third of US magazine revenue, the other two thirds being cover price and advertising. The value of that information network was confirmed by the business model of the trade magazines which I edited, which had no coverprice and, in the US, made equal amounts from advertising and database sales. The investment Packer made in my trip was to be returned by doubling the revenue of the trade stable using the knowledge newly acquired on that trip.

    Computers were instrumental in managing this volume of information, but there was only a nascent computer network, that information was collected exclusively via the postal and telephone networks and collated on computers in media company head offices.

    The surveillance state and the commercial publishing industry moved in parallel to extend those capacities as more of us began to participate electronically, but the model existed well before the World Wide Web or mobile phone.

    The importance of understanding this is to realise that the manipulation of people through collecting and collating information about their participation in public entertainment, spectacle and conversation is not new, and has always been the justification for funding and developing many of the public institutions that we consider to be important pillars of civilisation.

    Power, the individual and the State

    It has always been the case that institutional power, regardless of its philosophical justification, demands the sacrifice of the individual. Every solider is prepared to die for their General, Commander, King or cause. We bow down in worship because we understand, ie stand under, the Omnipresent power of our God, gods, their divine representatives or our local bully boy.

    It is the nature of the organisation to protect itself and an essential ingredient of that operating principle that no individual is above the law, the lord, Lord or the lore. The dark side of that principle is intimate state control of your person through surveillance and coercion.

    Venice, the Innovation Hub that harnessed the printing press and double entry accounting to dominate European commerce and intellectual life for two centuries used a sophisticated surveillance state to underpin it’s rule of law. Shylock’s pound of flesh was the sacrifice made buy every Venetian to keep the riches flowing.

    The notion that the common good is served by individual rights is a relatively modern proposition known as liberal humanism. It assumes that we can align personal desires with the needs of the state and so govern in the broader interests of the people. It conflates all of us, with each of us.

    Cooperative sensibilities are generally promoted by conservative governments in good times and progressive or radical governments in tough times. We sacrifice our individual freedoms for the common good when we are convinced we will be better off doing so. Sometimes that conviction stems from fear, at other times by opportunity, but the system always comes unstuck when the contract does not hold.

    Brexit, Trump, Erdogan, Duterte, and Bolsonaro are all made possible by the end of the continuous growth enjoyed over the last fifty years. Thanks to cheap oil, the ‘democratisation’ of debt and an increase in the global population by an order of magnitude we enjoyed three drivers of economic plenty that ensured we were each better off than our parents. Now those drivers have dried up, we fight over the scraps, yelling at each other “What about me?”

    The supreme selfishness evolving from a lifetime of unfettered affluence (literally) has now run headlong into the harsh reality that there is rarely enough to satisfy everyone and some of us get our share at the expense of others. The advocates of abundance-thinking do not work in African mines or live in trash mountains on the fringes of the world’s megacities. Europeans across the planet consider their freedom of choice as a benefit of the Enlightenment. The awful truth is that Free Thought has been built on an affluence that has been won by conquest.

    The relevance of this to the debate about how to best ‘recover’ the independence of the world’s media is to check our privilege. We have experienced the luxury of the welfare state, a free press and relatively even distribution of wealth, that does not make it our natural right.

    The battle for power using new communications technologies is only now taking shape. An attempt to preserve twentieth century business models because we understand them is the modern equivalent of defending horse-drawn transport on the basis of the revolutionary nature of the automobile. It is true, but it is irrelevant. It is a distraction from the real problem of maximising the benefits of the revolution and avoiding its greatest dangers.

    Reality Check

    I am not advocating that we should roll over to the narco-villians, arms traders or energy ogliarchs, pop the blue pill and harness ourselves to the matrix. I am, though, suggesting that it is not enough to invoke the righteous wrath of John Stuart Mills or the poetry of Pablo Nerada in the hope that we might shame the one-per-crore into putting down the reins of power and raising Vaclav Pavel from the dead so that he can run Google.

    Had governments a century ago thought through the impact of the car on the village, the inner city and the market town, transport policy may have been more broadly discussed and less nineteenth century infrastructure dismantled. On the other hand, maintaining horse troughs and street sweepers would not have proved terribly productive.

    The role of governments in the media is extremely chequered. The Australian Broadcasting Cooperation like the British version on which it is modeled has a long and proud tradition of independence and calling truth to power. On the other hand government media and communications policy has been shaped to benefit its powerful owners.

    We now need to start imagining and demanding the services made possible by the network and imagining the way we communicate in 50, 100 and 500 years. Along the way we will need to crack the heads of the constantly evolving rogues who mis-use it to gain personal advantage at the expense of the rest of us but that regulation is very different role from planning and building it properly.

    The printing press combined with numeracy and modern accounting to bring down the Church, empower the Guilds and fund the enlightenment. That involved bloody revolutions, religious fundamentalism and global imperialism at the same time as it nurtured the human rights of Europeans. It banished the epic poem and the oral tradition at the same time as it vastly democratised language, created the scientific journal and the newspaper.

    The Internet will have a similar revolutionary effect and will be just as messy. It is time we stopped bleating about what we are losing and started focusing on what we might build.

  • Cairo Tiling with no math

    Cairo Tiling with no math

    Got a ruler, a pencil and a piece of paper? You have everything you need to delve into the fascinating world of tessellation with pentagons.

    Cairo Tiling is a fascinating pattern named after some street pavers in the Egyptian city and part of a fascinating set of space-filling Pentagons that has been the subject of research by mathematicians and amateurs over the last century.

    That master of patterns, Escher has taken the pattern to another level.

    Writing on Medium, Catherine Halloway @femion, has provided some relatively simple programming code to generate Cairo Tiling. Her published pattern is shown above, the code for creating it is linked here and is reproducible by anyone who knows how to program.

    This article shows a very simple way to generate the pattern with no mathematics at all.

    You can do it at home with a ruler and some graph paper, or you can use computer drawing software to generate it. The great thing about this method is that you can fiddle a little bit to create many other related patterns.

    The first step is to rule a bunch of squares. At a minimum you will need four, I found it easier to start with nine.

    Now put a dot in one square, preferably half way between the corner of the square and the middle.

    … and repeat for every square.

    Now join that dot to the three closest corners

    … and repeat. There are your first set of hexagons.

    Now copy that and flip it over.

    If you are using pen and paper you can skip the next step.

    If you are using graphics software. Draw the dots and the lines on a separate layer from the squares, cut and paste to a third layer, then flip the third layer.

    Now move the flipped layer so its corners are in the middle of the first layer.

    You can see that I have moved my example half a square to the right and half a square down.

    If you are using paper and pencil, photo copy your hexagons, and put the two copies on a window with one of them face down (upside down or back to front), shift the top one around until it looks like the drawing below and trace the pattern onto the top piece of paper.

    Now trim it and remove the squares. Bingo!

    I have breaks at the corners of my tiles where I removed the square lines.

    Depending what you are planning to do with it, you can avoid that, or use that as a guide to generate square tiles, prints or fabric that repeat to produce the Cairo tiling pattern when they are joined together.

    Note that the pentagons are not symmetrical. That is because I have told you to put the dot in the middle of one corner of the square. With a bit of fiddling you can use variations on this approach to produce many of the patterns described in the Wikipedia article on Cairo Tiling. The point of this article is to give you a quick way to produce a fascinating pattern.
