Sour Cherries and Consumer Capitalism

Sour Cherries at Christmas
This Christmas I went up to the farm. Set between Canberra and Cooma the climate is cool enough to grow all the fruits and nuts that need winter chilling to produce their best.

Around the garden perimeter there are numerous bushes growing sour cherries and this year they are all fully laden. Sour cherries are bright red and very small when compared with the commercially grown sweet cherries. If you have not tasted them before the flavour might come as a surprise to you, this year they are tart and clean and without sweetness but to my taste they are delicious. The Christmas turkey was cooked outside in a barbecue and served garnished with the cherries. I would have liked to experiment with making a sour cherry sauce to serve in lieu of the cranberry sauce but time did not permit.

I picked a large basin full, about a kilo, and brought them home with me. I have preserved some in kirsch and some in brandy, they will remain untouched until the winter weather arrives, then I will decant the flavored spirit to warm a winter evening and perhaps do something creative with the boozy fruit as well even though I didn’t remove the pips.

I next pitted the rest of my harvest. A sour cherry with the stone removed weighs about 3 grams and as I wanted a total of 500gms that was quite a time consuming job but once done the rest was easy. I was making a cherry bake, similar to a clafoutis, whisking together eggs, sugar and softened butter, adding in plain flour and some milk then putting the mixture into a shallow baking dish. I put the 500gms of sour cherries on the top and popped it in the oven for half an hour.

Served warm with a sweetened vanilla yogurt it was so good.

Community & Consumer Capitalism 1st January 2015
As I never make the traditional New Year resolution this year I decided to break with my personal tradition. I decided that I would definitely do some research and some writing that explores the way our local communities are developing. This has been triggered by some of my own choices, one if which was joining a choir. This brought me into closer contact with the amazing musical fraternity that exists in the area. At a New Year’s Eve bash I attended, a continuous live show put on by some great local performers who created a fabulous low cost evening for the whole community and who for the most part actually paid to attend the gig.

Looking at newly emerging views on evolution that suggest our forbears actually out performed our hominin rivals due to a superior ability to cooperate, empathize and work together I am wondering if the competitive model of consumer capitalism is actually the main problem we need to deal with if we are to avoid climate disaster.

Time to do some more reading I think!!


Why Don’t We Get the Climate Threat?

Has the carefully orthodox behavior of climate scientists and the willful blindness of politicians led the world up a blind alley into a four degree or more dead end? Sadly I fear that may be the case and it is not due to careless science or incorrect claims about possible futures, it is the result of language and of politics.

On the language side, science, it seems, is incapable of making definitive statements about possible futures, instead everything is qualified, which would all be fine but for differing interpretations of the terms as understood by mainstream non-scientific members of the community. The general public will interpret ‘moderately likely’ as signifying that there is very little to worry about whereas the same phrase to a scientist might be interpreted as ‘get your skates on and pack the bag – in case.’

On the political front we face a different challenge. In the first instance few politicians have any scientific training and for a variety of reasons they tend to underplay the alarm calls. Assuming there is no preconceived bias or hidden agenda, once made aware of the gravity of the climate threat one might imagine that there would be an instant and effective response but this is not the case.
The conventional view assumes that economic growth is always good and we have to “grow the pie” if we would see wealth distribution more evenly spread through society. This view is promoted through platitudes like “a rising tide lifts all the boats” forgetting to mention that it may also drown those lacking a flotation device or that big boats take up much more space in the harbor.

Politicians see a growing economy as way to keep everyone happy, a guarantee of jobs and money for the next three or four years so that they (the politicians) can feel comfortable about re-election for another term. But they fail to see that the illusory rising tide of wealth brings with it a rising tide of pollution.
We live in a finite world, we fill it with the detritus of everyday life, industrial waste, pollution from coal-fired power plants and factory farms and we expect to escape unscathed. We require services from the natural world to maintain clean air, to filter our drinking water, to provide our food but we spray it with chemicals, cut it down, dig it up, build on it and in doing so we destroy the ecosystems on which we are dependent.

In 1994 Mathis Wackernagel and Professor William Rees of the University of British Columbia developed the concept and established the methodology for calculating humanity’s “ecological footprint”. In essence it is way to calculate our impact on the earth’s capacity to maintain clean air and water and re-establish natural systems disrupted by humanity..
Mathis Wackernagel explains the concept in this youtube clip outlining a way to estimate natural resource use and avoid ecological bankruptcy.

According to the Global Footprint Network the world is already in overshoot and annually uses 50% more resources than can be regenerated and produces 50% more waste than can be absorbed by the planet in a year.

Today we do not live in a world that has room to expand and grow without let or hindrance, that world ended about fifty years ago. Rather we are faced with a planet under stress from over exploited resources, an economy still based on planned obsolescence and a world polluted by its own waste. We frantically dig up any useful minerals, turn them into electronic toys like iPads, smart phones and notebooks that are discarded within 2 or 3 years and mostly then go into a landfill that leaches poison long into tomorrow.
Our world is a world created by a market economy that is addicted to economic growth and this is often overlooked and excluded from the climate conversation, or perhaps only referred to in terms of avoiding the need to take action. In Bermagui recently at a talk covering “The Politics of Climate Change” Dr Ken Henry explained the economic conundrum in terms of a market failure due to environmental impacts being treated as externalities. An externality is something that is not included in the accounting because it has no effect on the bottom line.
Business pollutes the atmosphere, the land and the water only because we do not require them to pay for the damage caused by their emissions and their waste products.
If we are to meet our global warming target of not more than 2degC increase above pre-industrial global average temperatures we must control these externalities and we will also need to abide by a “carbon budget” that does not exceed 1000 GigaTonnes of emitted CO2 as has been demonstrated in the United Nations Environment Program Synthesis Report ‘The Emissions Gap Report 2014’ published in November 2014 There is also an Executive Summary available to download.

In order to stay within the 2degC boundary it seems that we will need to be carbon neutral by 2055 and have zero net emissions worldwide by 2080. Unless there is a massive change of direction we will miss our 2degree target and end up in a world with four or five degrees of global warming.

In the book ‘Four Degrees of Global Warming – Australia in a hot world’ (published by Routledge and edited by political scientist Peter Christoff) some of our top scientists explore the likely consequences of a Four Degree World for Australia.
Scientists Will Steffen and David Griggs look briefly at historical records of collapsed civilizations and conclude that while climatic shifts were certainly important in the collapse there were probably other contributing factors. They suggest that, in line with ideas expressed by Joseph Tainter and Jared Diamond, societies that cling to core values which have become dysfunctional due to changing circumstances (like perpetual economic growth perhaps) or have become so complex that they lose resilience, may have predisposed themselves to a negative outcome.
In the chapter on Marine Resources Ove Hoegh-Guldberg, Elvira Poloczanska and Anthony Richardson point out that the ocean has buffered us from some of the effects of global warming by absorbing over 90% of the heat generated by the enhanced greenhouse effect and 30% of the additional carbon dioxide pumped into the atmosphere by our industrial activities and life choices.
It is not clear to what extent the oceans can continue to protect us but it is clear that they have become warmer and more acidic and that this will impact on marine life and on economically important fisheries

Science seems generally unwilling to make pronouncements about sea-level rise, due perhaps to a lack of precise understanding about mechanisms involved in the melting ice sheets of Antarctica and Greenland. These large ice sheets will melt if the world continues to warm unabated and when they do all the world’s major cities will be battling for survival just as Venice is today.

Records for heat are constantly tumbling, 2013 was the hottest on record and now we hear that 2014 will probably match or even exceed that. As we move into this 2014-15 summer we are already facing record heat in many parts of NSW and we have not yet even reached 1degC above pre-industrial levels. The bush fire season is fast approaching, much of the State is still very dry if not actually in drought and there are questions about whether or not it will be an El Nino year.

It seems likely that at 4degC of global warming Australia will become very uncomfortable and looking fifty years into the future some parts of it may even become uninhabitable.


To Change Everything we need Everyone

From National Science week through to the September Climate events in Bega and Moruya (and the rest of the world) we have seen a multitude of actions, walks, marches, picnics, church bells rung by the Anglican Church all round Australia and more. Hundreds of thousands of people trying, with limited success, to “speak truth to power” on the subject of weather, sea level rise and the likely impacts of dangerous climate change.

Ringing the Church Bell and celebrating the Anglican Church divesting its fossil fuel holdings at the Moruya Climate Action Picnic

All this is just the latest skirmish in a battle that started at the Rio Summit in 1992 when a spotlight was turned on the patterns of production, toxic components and poisonous waste. The summit recognized the need to replace fossil fuels with renewable energy, to develop public transport in order to reduce pollution and congestion in our ever growing cities and the recognition of a growing fresh water scarcity. Our current report card is looking pretty sick when it is compared against this list of problems that were known and assessed twenty-two years ago. Had we acted responsibly at that time we would now be in a position to really look forward to safe and clean future for ourselves, our children and our grandchildren but as it is we are faced with a world that is teetering on the brink of disaster sometime in the next 30 years or so.

The planet has its own mechanisms that maintained the comparative stability of the climate throughout the 3.8billion years since life first took hold. During that time the climate has shifted from very warm to icy cold and back again more than once, so it seems that sometimes the control mechanisms are overwhelmed. But the planet works on a time scale so different from our human perspective that the whole of human existence is but the blink of an eye.

The fingerprints of humanity and particularly advanced economies is clearly evident in the rise of carbon dioxide levels since the industrial revolution. While the rate of increase may be slowing the total is still going up. In the last twelve months atmospheric CO2 reached 400ppm a level that has not been seen for the last eight hundred thousand years and possibly not for the last 20million years. And emissions are still rising. The CSIRO Global Carbon Project advised that CO2 emissions in 2013 were in excess of 40billions tons of which 36billion tons came from burning fossil fuels and from cement production. There has been an increase of approximately 65% in fossil fuel emissions since the Rio Summit.

On current projections the world is looking at a probable increase in average global temperature of around 3.2 – 5.4degC above the pre-industrial levels. Given that we have accepted that a 2degC rise is likely to lead to dangerous climate change the mind boggles as to how the political class and the fossil fuel lobbyists will sell this concept as an acceptable outcome. One rather thinks that obscuring the information may suit them better.

There are other problems that come with delayed action, in particular the inexorable rise in sea levels. Once we see the ice sheets of Antarctica and Greenland start to melt we may never be able to stop or slow the melting ice.
Over time the sea levels will rise. It will probably take centuries, there is no real understanding of how or how fast the ice will melt, but it does seem that eventually all our coastal cities will vanish beneath the waves.
We are of course also losing our biodiversity at a rate that is believed to rival or even exceed the great extinctions of the past. This loss of complexity makes our ecosystems vulnerable and regardless of our skills and determination to control the natural world we remain dependent on functioning ecosystems.

There are hopeful signs on the horizon, we still have time to change our current direction and avoid the worst predictions. Action by China to limit pollution by burning less coal, and actions in the USA including the State based renewable energy initiatives are hopeful signs. Even here where we have seen so many initiatives undermined there is still massive public support for renewable energy. At a recent forum held by the Solar Council in partnership with Solar Citizens and supported by the multitude of small businesses specializing in renewable energy prospective attendees had to be turned away as they could not be accommodated in a hall that seats 600.

There are things that we as individuals can do as well, things that may just help to tip the balance. Small things like buying local produce, maybe selecting grass fed instead of feedlot or grain finished meat, being aware of the food miles that are in the shopping trolley and taking action where and when we can to move our own consumption patterns onto a sustainable trajectory. It will not be the easy transition that we would have had, had we acted in 1992 and it will take us all to make the change.

The worldwide climate action that took place on Sunday 21st September this year was initiated by 350.org and it was undoubtedly a magnificent success. Their mantra was “To Change Everything We Need Everyone”


Four Winds at Easter

Four Winds is a biennial Festival held at Easter on alternate years in the little town Bermagui and at an amazing outdoor location in Barragga Bay. It is a festival of music and artistic endeavour and it takes place over four days.
There is always a free concert held in Bermagui and this year it was held at the Bermagui Fishermen’s Wharf. The proceedings opened with a Welcome to Country, a sandy space had been created for the Djaadjawan indigenous female dancers who were part of the welcome.

The Pelican, an ocean going research catamaran formed the stage and performers were ferried to their destination on a punt.

Taking a punt, a great way to travel to the gig.

As the evening progressed the Pelican revealed she was really well dressed for the occasion, the sun went down and the lights came on..The Pelican at 4 Winds
It was great evening although some of us on the balcony found that from time to time the chatter drowned out the music. But this was Friday and just the start of a weekend full of magical music in a location widely referred to as Nature’s Concert Hall. It is hard to imagine a more beautiful or more appropriate setting for such musical talent. The Sound Shell that provides brilliant acoustics, the natural amphitheater, the lake and the water lilies that could have been taken from a Monet painting…GE
And of course the music. Whether it was the string quintet performing against a backdrop of waterlilies, music so beautiful it catches at your throat and almost brings tears to your eyes..4 Winds string quintet or Dejan Lazic demonstrating the depth of his talents on the new Overs piano took us on trip through time with the work of three composers that stretched across three centuries. Domenico Scarlatti who was writing in the early1700s, Franz Liszt from the nineteenth century and finishing with twentieth century composer Bela Bartok… or Giovanni Sollima who can do such wonderful things with a cello that you think he must have somebody else with another instrument hidden somewhere close by…GE
Four Winds was all this and so much more.

The last week of the Climate Change MOOC

The eighth week of the “Climate Change, Challenges and Solutions” MOOC has come to a close and for me it has been a really worthwhile experience. In the final week we approached the question “Is the future of the climate still in our hands?” Very clearly it is within our reach to either maintain the current path of high, and growing, CO2 emissions or to change our direction.
If we choose not to change the way that we create power by burning fossil fuels, if we persist with a culture based on a dig it up, use it and throw it out philosophy then our outlook is very poor indeed. Travelling that path, by the year 2100, atmospheric CO2 will have reached levels that exceed 1000ppm and will possibly be as high as 1500ppm. This will mean that the average world temperatures will perhaps be 6degC warmer than today. It would take one million years for the earth’s natural weathering systems to remove this amount of CO2 from the atmosphere.

CO2 reached 400ppm late last year. It hasn't been that high for 650,000 years

Travelling this path will mean more violent weather events, more floods, heat waves, wildfires and droughts. I doubt that our current flawed economic and social system will survive these shocks but if it did survive we would then be facing a slow but inevitable rise in sea level as the Greenland and Antarctic Ice Sheets melt, an unstoppable increase that will raise sea levels by up to 70 meters. CO2 persists in the atmosphere for a long long time and this is one reason why we know that the timelines for reducing our emissions are critical.

There is an alternative.
The current trajectory will see us locked into rising emissions, higher temperatures and long term devastation but we can change this outcome and still make a measured transition to a new way of living. If we base our future on fairness, sustainability and equity we could actually use this crisis to embrace change. Science has given us the tools and the all the information that we need to move to a sustainable and resilient world, only vested interests and politicians stand in the way. We can change the politicians and now even some of the vested interests are beginning to recognise that they too need a sustainable world order.
Clearly we must price pollution at a rate that is proportional to the damage caused to the ecosystem, the economy, the society and the individual. We probably need to support sunrise industries that will help to cut pollution, industries like wind and solar power and of course we must stop burning fossil fuels. These critical first steps need to be taken in the near future so that we can start to reduce our emissions during this decade, meet or preferably exceed the undertaking we made to reduce our emissions.
Once we have started along this path we can turn our minds to finding effective ways to draw down atmospheric CO2. Maybe carbon capture and storage will finally become a viable option, although I doubt if it will ever be a cheap one. Leaving forests standing is a very good way of locking up carbon for hundreds of years and the amount of carbon stored continues to increase throughout the life of the trees. Tackling our throw away society and demanding that industries find a use for all their waste products so that instead of a linear system of constant through-put we have a circular system that minimises new resource input and virtually eliminates waste.
Bearing in mind that true sustainability also requires equity to be successful, wealthy nations like ours should be prepared to help disadvantaged nations to move directly to a clean renewable energy supply skipping the dirty coal fired power that destroys the climate. They may be more successful than we are, because the large vested interests that are keeping fossil fuels alive and preventing the development of distributed power are not in such a powerful position as they are here.


Climate change, mitigation and adaptation

We are now into week seven of “Climate Change – Challenges and Solutions” and this week we examined the possibilities and options for mitigation and adaptation. On the mitigation front, having seen the pitfalls of geoengineering solutions looming large on the horizon we turned our attention to the built environment, which is responsible for a high percentage of our emissions and also to renewable energy which can give us a good start in reducing them.
I have some background in this area so I was aware of the huge strides that have been made in the design of energy efficient buildings, but of course most of the housing stock and many commercial buildings pre-date sustainable design. Much of our housing is built close to the ocean and only a few metres above sea level, will it survive repeated major flooding as sea level rise and storm surges impact on the coast? Will it be able to deal with the rising temperatures that are anticipated?
We looked at the impact of heat islands in built up environments and the increased number of deaths that are related to heat waves. This course is being run out of the UK so the question of wild fire was not even considered but flooding was certainly discussed.

We were asked to review the built environment in our own locality. This small house, still under construction, will be adequately insulated, it faces due North (correct orientation for the southern hemisphere) and has deep eaves. This will allow winter sunlight into the house and being small in size it will be easy to heat in winter. It has one large west facing window which could be a problem in summer but an external blind will take care of that. The eaves will shade the glass in summer and there is cross ventilation to assist in cooling. I think there will be a degree of climate resilience built into the house.

This architect designed house is an example of a house built before climate change became an issue. It faces almost due west to take advantage of the views over the lake but because it has a very wide covered deck it wouldn’t have too much of a problem until fairly late in the day and it would be easy to drop canvas blinds along the deck. Being built on a slope it has some rooms under the living area which will remain cooler and give some resilience as the climate warms.
I think that where site conditions have been properly considered during the design stage the old housing stock will have a level of resilience but probably much of the developer led housing that has been built in the last twenty or so years will be pretty much a write off eventually.
And to give an idea of the location a map because I simply couldn’t cope with the suggested geo tags. The star is the existing house and the teardrop is the site of the new build that is underway.
House location
The second half of the week was devoted to renewable energy. It is clear that this is the “get out of gaol (almost) free” card. The UK has about 11% renewable energy at the moment and are looking to reach 30% by 2020. There are some active anti wind organisations and they are also going to build a new nuclear power station. They seem to think that nuclear is cheap (ha ha!) and renewables are expensive which is crazy.
Denmark on the other hand has 30% renewable energy now and is expecting to have 50% by 2020 and 100% renewables by 2035. Go Denmark! I think it has been made quite clear that one of the biggest obstacles to dealing with climate change is the entrenched opposition from fossil fuel protagonists. We can’t afford to let them win. It is also interesting to note that the gulf states are putting in solar power in order that they can get the most out of the last of their oil reserves by selling them to people like us who refuse to recognise the reality we are facing.
Next week we are looking ahead to the medium and longer term effects of climate change. I approach it with some trepidation.


Changing seasons

Folk Festival
Here on the Far South Coast of NSW the late summer and early autumn period is a time taken up by local festivals. From the Cobargo Folk Festival in February we move in March to the Seaside Fair and the big sculpture exhibition “Sculpture on the Edge” culminating this year with the first Fire Festival. This was held on the headland and there was music provided by Gypsies from Outer Space, food from Arincini Bambini, a community picnic among the sculptures and finally as darkness was closing in the fire sculptures were lit.

The first Fire Sculpture is ignited ah=nd it is followed by the small sculptures produced by the primary school students for the occasion..

There is something about fire that speaks to a primitive instinct in us, perhaps reminding us of a time when humanity depended on fire and the hearth was the heart of the house, or maybe that is just my imagination and my northern heritage speaking. Certainly fire in this land is much more dangerous but even so as I see the drift of smoke across the valley and catch the scent in my nostrils it speaks to me of warmth and winter. How different is the smoke of wildfire in summer, linked with high winds and searing heat it leaves everyone on edge, restless and with an underlying current of fear.

Then in April there is the Tilba Easter Festival and on alternate years the Four Winds Festival celebrates music. Planning for Four Winds next year is well under way. This remarkable three day festival features classic, cultural and world musicians, it is held in a natural amphitheater on a rural property and there are additional performances held in Bermagui venues. http://www.fourwinds.com.au for more information.

I spent Easter this year with my daughter and her family at the farm near Cooma. We planted trees on the river bank, we gathered chestnuts and rosehips and visited another farm close by which sold fresh organic raspberries. We joined the children in an Easter egg hunt, and together with friends we lunched on the verandah in fine style. Back at home I have now frozen the raspberries and made some rosehip jelly.

Lunch at the farm

But today far from thinking about festivals and Easter I just wanted to get the garlic and the onion seedlings planted out into the garden. Two days ago I tried to prepare a garden bed, the last of the vegetables had been cleared out previously but at that time the ground was very dry and hard so I decided to wait for some rain before preparing the bed.

This is my Vegenet exclusion device

I finally decided to try again but the ground was set like concrete and even with a hose running onto it only the top couple inches were workable.
I gave up again but yesterday it finally rained, there was 18mm in the rain gauge and happily the thunderstorm had delivered enough moisture to make planting out possible. The onions and garlic are now in the garden and hopefully protected by the vegenet. They need protection because a few days ago a wallaby raided the grape vine and the sweet potato and ate all the leaves and a week before the fox got all chooks. Much as I enjoy the wild life there are moments when I wish they would stay on the other side of the fence, and imported predators like foxes are not welcome at all.
