Rohan Nelson was our third CSIRO bod to talk. He dragged some of the stuff we had been learning into possible policy directions. I particularly liked his comment that science provides pathways to solutions, rather than answers all by itself. He led us through the impacts of global warming and yes, it made sense. Climate change (specifically rainfall, temperature and wind) impacts biophysically (crops/pastures, water, forests, fire being of particular importance) which has an economic impact (on productivity, farm income, regional economies, for instance) and then social outcomes (employment, social capital, vitality and well-being all being affected).
What I liked about his talk and our questions of him was that science was making sense as a communications medium and as a tool to help us deal with the effects of global warming. Not a silver bullet, but something very useful.
Rohan also gave the tidiest explanation of the Southern Oscillation Index (SOI) I have ever heard. He uses the SOI to help governments sort out possible problems before they occur and to provide early responses to them and help farmers adapt better to problems. Science as a risk management device. Kind of like history, really :).
After Rohan Michael Smith spoke. We gave him extra time and asked him for notes, which was just as well, because he was terribly nervous.
Michael wants to change the world in five minutes flat and has a ton of ideas for doing it. Note to organisers of future fora, make sure you include a child care worker *always* because it was she who thought to ask Michael for a list of the things he had talked about so we can evaluate them and work out what we can use in our response. He threw ideas at us and we loved it - but paper helps :).
Michael was not positive about climate change, but he was sensible in how to go about changing reponses to it. He looks at what works and tells people about the success stories. This means that there are positive examples and people have paths they can tread. He wanted to tell us how to think, but he also has a bunch of good information in his brain and yes, we're going to think for ourselves but pick his brain.
What I liked in particular is that he is part of a team making energy efficiency case studies open source. He explained that this is the work of several bodies, including CSIRO and Engineers Australia. I've never seen any reason why the rest of the world can't get its development without making the stupid mistakes we made, and using open source is one way towards this, especially when the group is working specifically with China and India to help this happen.
In Canberra he and others are setting up "see change hubs" where groups of 10-20 people work together in each suburb to disseminate ideas and to link with experts. He explained it was the environment version of Neighbourhood Watch. It made me think of blog communities :).
Following him, Ayesha Razzaq from ACTEWAGL gave us a quick run-down on actual energy administration. Some lovely bubbles were burst at this point. We have a wind farm and not enough Canberrans want to pay the extra for energy from it, so it's sitting idle, for instance. Despite the fact that 98% of electricity in the ACT is from the national grid (ie fossil fuel), getting people to demand green energy is not as simple as saying "we want this to happen".
The two big areas we need to reform in Canberra proper are home energy usage and transport fuels. Only 8% of commuters use the bus system. And renewable energy costs 3-4 times the amount of coal energy. Lots and lots of equations started floating through our minds as we thought about how to deal with all this.
There are some government initiatives. Federal government goals (the Mandatory Renewable Energy Target) are low - 4.8% by 2010. The NSW/ACT state based Greenhouse Gas Abatement Scheme is all about carbon trading. GreenPower is for those not happy with Australia's national policies and creates choice for green products (I have notes somewhere on how it works, but I lost them - at this stage I was listing what was going on and looking for where we can do more rather than sorting out scheme specifics) and the Greenhouse Challenge is industry and government working together. Someone noted later in the day that industry and state governments were much more willing to work on these issues than federal government. Victoria and NSW for instance are both working on renewable energy targets which intend to top up the low Commonwealth targets to something more useful: 10% by 2016 for Victoria and 15% by 2020 for NSW.
Useful tidbit: The ACTEWAGL website apparently has an energy saving calculator.
Ayesha briefed us on the cost of solar panels. The scientists had been waxing enthusiastic about them and she poured quite a bit of cold water on that. Private households would be able to get about 10% of their power from solar panels and the panels would cost thousands that would not be recouped in savings. Until solar panels come down a great deal in initial cost, they are just not practical for widespread use. Solar hot water systems are more affordable, apparently. And ACT scientists are working on that price problem.
Other tidbit: if you're going to buy green energy, google for "Green Electricity Watch" because not all green products are equally beneficial to the environment.
This is not the most orderly report I've ever produced, is it? I think it shows that my mind is still trying to put things together in various configurations and try to sort out what we can do. One thing that is very clear is that doing nothing about global warming is not an option. Only one more section to go, though, for today. See you in the next blog entry.
