Free Radicals: Series 2 – “When the Rivers Run Dry”

Date: Thursday 7 September 2006
Time: 6.00 -8.00pm
Cost: Free
Where: Courtyard Café

Free Radicals – Our monthly series of science and sustainability talks and debates is back in a new time zone, Thursday evenings, and a new venue, the Museum’s Courtyard Cafe.

Fred Pearce calls for a ‘blue revolution’ to avoid the impending global water crisis in his latest book, When the Rivers Run Dry. The author’s 15 year odyssey researching water issues has taken him from our own Murray Darling River system to the banks of England’s Thames River.

In his only Sydney appearance he reveals the personal stories behind failing rivers, barren fields, desertification, floods, water wars and the death of cultures. Locating our regional water crisis in a global context, he also offers a way forward to meet this global challenge.

Supported by the Brisbane Riverfestival, the British Council (Australia) and Random House publishers.

Nice rain, shame about the dams.

Victoria st flooded 15/8/06

With water on the menu at the next Free Radicals (Sept 7th) it seems timely to look at the state of Sydney’s water supply. After some great rain in the city in recent weeks it is good to see the level in catchments going up. With the new access points on the Nepean and Warragamba dams allowing access to deeper water supplies the Sydney Water supply graph looks better.

But even with the figures now reflecting the extra capacity there has only been a marginal percentage increase in available storage (40.9% – 41.1%) since august last year.

I was shocked to note that although the available volume has increased by 88,500ML or 10% in the last 12 months, with Sydney’s current daily water use standing at 1,410ML, there has been a decrease in dam levels over the last week and in fact a 90,000ML reduction since April.

I was also startled to see that overall consumption during winter is not dissimilar to summer usage figures (do we take longer showers in winter?)
That is total Sydney usage and takes no account of any population increase since summer (about 560 people a week).

All of this highlights that though we live in an advanced, educated, rich country water is still an issue and we can not be complacent, even in winter. A recent article from WWF brings this home with reference to a number of Australian examples (not just Sydney).

Free Radicals 2.1 – Space and Spirit

Margaret Wertheim

The first event on the Free Radicals series 2 calendar was a talk by science critic Margaret Wertheim. Margaret delivered a presentation titled Space and Spirit: why science and religion together are driving us crazy.

This was a thoughtful and interesting look at the development of science from the middle ages. With slides of religious art to illustrate the point that as scientific understanding developed, Christianity, as seen through religious art, developed a changing perspective.

Margaret asserts;

At the birth of modern science in the seventeenth century no one imagined that science was articulating the whole of reality, but increasingly, since the enlightenment, that has been the claim.

It is this increasing claim of science to explain the human condition, our origins and the basis of ethics which Wertheim said explains the antipathy between fundamental religions and science. She went further to suggest that the antipathy goes both ways with “literalist” scientists unprepared to accept the legitimacy of any religious belief.

Wertheim is widely hailed as a rare science writer with an ability to clearly critique science for both erroneous methodology and the legitimacy of assertions on such topics as universal origins and human ethics.

Wertheim suggests that we need to find a new way of talking which allows for both scientific and religious understandings to contribute. Only in this way she asserts will we be able to progress to a world where science can contribute more than just facts to the everyday person.

Free Radicals is about sustainability and I think that the issue Margaret was talking about is relevant here. There are two common stands against acting on issues of sustainability firstly non-belief in the evidence and secondly that the solutions are economically unusable. Both are questions of belief, belief in the issue and belief in our ability to provide easy solutions.

In research carried out here at the Powerhouse in establishing the Ecologic exhibition people told us they didn’t want to come away from a visit feeling guilty, but did want to see solutions.

The solutions people are looking for are reflected in the acceptance of economics as an argument against Greenhouse solutions. I believe people want to defend themselves against science asserting that we need to change our behaviour to combat ecologic disaster.

In a street interview for our second ever Free Radicals, a debate about the NSW desalination plan, a person said they wanted a water solution found for Sydney so they could wash their car again. The public wants to be assured that problems will be solved so that they don’t have to change. The perception that real long term solutions may only be found in changed lifestyle choices is unacceptable to many people.

In the same way that religion wants to hold its ground against scientific assertions of origins and ethics, so society wants to discount science’s claims to any right to comment on our lifestyle.

The film he made to change the world

Al Gore is in a film, according to many reviewers and pundits one that is set to take the 2007 Oscar for best documentary. Following in the wake of Michael Moores the Awful Truth An inconvenient truth looks at the involvement of politics in world issues.

An inconvenient truth is a film literally made to change the world, in all senses of the statement. “The former next president”[sic] endeavours, and if enough people are brought to see it he should succeed, to provide the information people need to change their behaviours. The longer term result is a change in the environment of our planet.

Essentially a lecture Gore admits to delivering over a thousand times, the film outlines the truth behind the global warming crisis and then delivers a rebuttal to the reasons for doing nothing. I would love to go further about the content– but it would spoil the film and it’s not why I’m writing this.

If you are versed in global warming don’t see the film to hear anything new, it may be said more clearly and may be painted with pretty pictures but it’s nothing that most of us haven’t heard before.

But do see it to encourage everybody you know to see it. This film and the presentation it is based on will convince 90% of people that this is surely an issue we need to pay attention to, and also that we can do something about it.

Something new this film brought home for me was how as a species we continue to enjoy ignorance. Recent research here at the Powerhouse Museum suggested that people are not interested in finding out about issues of sustainability.

As a confirmed believer in humanities 100% complicity in Greenhouse climate change I was startled by the number of people in the cinema with me who were shocked by what they were seeing as NEW facts, facts I presumed everybody was aware of. These were educated people and I must assume they have decided up to that point to keep themselves in the dark.

The film it self points out that although scientists are 100% convinced about this crisis, its causes and possible outcomes, over 50% of media articles present greenhouse and climate change as uncertainties. Here is an example from the SMH

More on this later.

The majority of people believe the rhetoric, or at least accept the doubt offered by continued media spin. Thus allowing themselves the freedom to continue doing what they are doing.

“An inconvenient truth” is essentially a powerpopint presentation about the truth of global warming. Gauging from the reaction of audience members it effectively presents facts in a clear and concise way. What the writer (and most readers) of this article have been trying to do for a long time could effectively be achieved by ensuring every sceptic, or at least unbeliever gets along to the film.
