Simon Wilson got an early laugh as he announced himself as “speaking on behalf of the Lorax.” He was an excellent chair, knowledgeable and entertaining.
A sobering fact of climate change to start with: if the earth’s temperature continues to rise at the current rate of increase, in 80 years the whole earth will be 4-5 degrees warmer on average. The sea levels will be at levels that they were 55 million years ago, and there will be virtually no ice caps. This will cause huge migrant populations, with flow-on effects including food shortages and economic problems.
To stay within 2 degrees of our current temperature, we have to reduce our CO2 emissions. Wilson was an excellent chair: one of his first questions was, on the scale of 1 – 100 in optimism in our ability to bring about change, with 100 being ‘it’s all going to be fine,’ where does Tim Flannery sit? In short, he was close to 1 seven years ago when the Copenhagen Climate Council (which he was involved in preparing for) failed to bring about change: he is now at 50 or 60, since the Paris Agreement in 2015. The significance of the Paris Agreement is that “we now have unified, consensual agreement to end the fossil fuel era.”
To put some context around this: Tim Flannery is one of the world’s experts on and authors about climate change. He is chairman of the Copenhagen Climate Council, an international climate change awareness group, and from 2011 was the Chief Commissioner of the Climate Commission, a Federal Government body providing information on climate change to the Australian public. Until he was sacked by new Federal Environment Minister Greg Hunt.
One of the key ways that Flannery thinks that as nations, we can make drastic cuts in emissions, is by shutting down all coal-powered Electricity plants. And his renewable energy of choice is something I hadn’t previously heard of: Concentrated solar power. “There’s a lot of way of doing this – mirrors, tower, super-heated objects.” You can store it in a lot of places – silica sand being an example. Port Augusta coal-powered Power Plant was the biggest emitter of CO2 in Australia: it has now been replaced by CSP. Sundrop Farms, an agricultural farm that is run using this technology, now grows 10% of all of Australia’s tomatoes. The biggest benefit of CST is that it can make our most worthless land – desert land – the most productive agricultural place on the planet. The challenge with regular solar power is that it can’t be stored – it needs a back-up for days that aren’t sunny.
Wilson put it out there that if you breed despair, we feel hopeless. But then if you generate hope, you are in danger of people just going well then we won’t worry about it – we’ll carry on as is. To this Flannery noted, “The single greatest impediment to implementing environmental change is that we haven’t got everybody along with us.” But despite all that there are solutions, and promising trends. China has started to close down a lot of their coal-powered plants, in favour of nuclear plants, and more renewable energy plants – and they are scaling up their electric car manufacture hugely.
The trend of electric cars, and driverless cars is something Flannery thinks is going to make our world unrecognisable within 20 years. My husband has been putting off learning to drive because he figures nobody will be soon – he may well be right. Certainly by the time my kids are grown up, they will be watching out for robot cars on the roads – or perhaps being driven by them.
Flannery thinks that developed countries have passed peak oil use, and that the idea that developing countries still need to go through this stage is a strategic challenge that these countries have to work through.
Politics and the environment
Here’s where things get revolutionary. Flannery believes that our system of government has taken us as far as we can go. He believes that decisions about money shouldn’t be in the same space as decisions about how to deal with climate change. With climate change, and anything that affects the whole world, we need to select citizen juries and give them all the facts scientists know. Flannery gained an enormous respect for the common sense of people while Climate Commissioner. “We have to break the nexus between money and corruption. If we can do that, we would get a long way forward.”
The conversation shifted to carbon credits at one point: at the moment, the price for carbon credits is random. To make any true difference to our CO2 emissions using our current methods we’d need to plant all of North America in forests. Flannery says, “We need to start making investments that are required to make a difference. We need to both reduce emissions, and find new ways of dealing with our world via technology.”
The reason Flannery has hope stems from a combination of factors: the two-year flat-lining of Co2 emissions, the fact we have the Paris Agreement, the changes in technology and social networks are among them.
There were some good audience questions at this session. How do we prepare for what is coming? Flannery quipped, “NZ needs to live up to its reputation of being clean and green. You guys have some great innovators. The government needs an innovation fund to foster this in areas we’ll need in the future”.
Ultimately, “We have to start preparing to adapt to the unavoidable. We need common sense regulations in place to deal with that.”
I am going to be reading more about this essential topic – I think we all need to. This is the world we are leaving to our children and grandchildren. My sons will still be alive in 80 years; I don’t want them to be living in a ruin caused by us.
