(Tasmania) Parents Produce 'Climate Change Snapshot' For The North-West

The Advocate - Lachlan Bennett
Many parents are struggling to adjust their lives to coronavirus conditions but some won't let the pandemic distract them from the bigger picture.

A group of North-West parents who are passion about fighting climate change have spent the past couple of months developing a resource to help tackle the issue.

The Tasmanian "Climate Change Snapshot" provides a clear and concise picture of the causes and effects of global warming and explanations of key concepts, such as the Intergovernmental Panel on Climate Change.

It also outlines what action has been taken by state and federal government as well as councils from across the North-West.

Mount Hicks mother and educator Tanya Linden hoped local government and Coasters could use the document to learn "how climate change is going to affect us locally" and what was being done "to mitigate and adapt".

"Although there are sporadic things happening, what we're seeing is incredibly hopeful and I think in Tassie, this whole pandemic has shown what good leadership looks like," she said.

"So there's amazing capacity at this stage for us to come out of this (COVID-19) in a way that not only builds the state stronger but also builds the environment."

Mrs Linden said the snapshot painted "an incredibly hopeful picture for the future", from the ongoing development of renewable energy to the "good leadership" of local governments such as Waratah-Wynyard Council.

But she said the snapshot revealed "gaps everywhere" in the response to climate change, from education to the varying levels of action by different regional authorities.

"It's like no one is really putting their hands up to be as innovative as we could be," she said.



Mrs Linden said good leadership was key and Tasmania had "everything we need to go forward in a sustainable way that has a very positive impact on our climate future".

The document has already been presented to organisations such as the Cradle Coast Authority and Mrs Linden said the response had been "incredibly positive".

(AU) Is COVID-19 The Dress Rehearsal For Climate Change?

The COVID-19 pandemic has had far-reaching consequences, changing society as we know it.

Before the crisis hit, Australia was facing a climate emergency with the worst fire season to-date – taking lives, devastating towns, decimating forests and wildlife, and causing widespread fear about the future.

There has been a push for governments and companies to continue their focus on sustainability. But is it appropriate to be talking about climate risk during a global pandemic that is barely contained?

The impacts of climate change will be far-reaching for organisations, both government and private, but the repercussions of COVID-19 show that many are not ready to manage the climate risks.

Throughout May, UNSW Business School’s Responsible Business Program coordinator, Dr Louise Fitzgerald, with Tanya Dellicompagni presented four online discussions titled 'Future-Proofing Business', bringing together researchers, academics, business leaders and practitioners.

For the first discussion, four experts spoke about what can be learnt from the impact of COVID-19 about the capacity of business to manage climate risk.

What climate risk means for businesses

Honorary Associate Professor Mark Diesendorf, a scientist from the Environment and Governance Group at UNSW Sydney, says there are two main types of climate risk – the physical risks and the economic and financial risks they cause.

The physical climate risks include natural disasters, which are increasing in frequency and have direct impacts on tourism, agriculture, infrastructure and more.

These impacts impose economic and financial risks in the insurance sectors and banks, cause stranded assets, impact credit ratings and reputation.

A/Prof. Diesendorf explains COVID-19 is connected to these risks as the pandemic reduces imports and exports, impacts employees and the global oil and gas sectors.

“As far as imports are concerned, there is a reduced availability of products and components and a disruption of our supply chains, reduced overseas earnings,” he says.

A/Prof. Diesendorf says there has been a huge drop in global demand of oil with an international price war which has seen prices plummet.

“Some would say that might be a good thing to assist the transition to renewables.”

Challenges in addressing climate risk in Australia

Professor Jeremy Moss from the Climate Justice Research Program at UNSW Sydney says one of the challenges businesses face is how to decarbonise their operations and switch to renewable energy or cease operating altogether.

“The climate transition in Australia is operating with one hand tied behind its back because of the way in which fossil fuels are subsidised and treated favourably in Australia,” Prof. Moss says.

A recent report by the International Monetary Fund noted that Australia spends around $47 billion every year on subsidising the fossil fuel industry, for example through the diesel fuel rebate scheme and accelerated depreciation of assets.

“This poses all sorts of challenges for businesses who aren't directly receiving those kinds of subsidies,” says Prof. Moss.

What direction should businesses take?

“I think we need to tell businesses and show businesses that there are actually huge opportunities in responding to climate change,” says A/Prof. Mark Diesendorf.

He says the world's largest asset manager BlackRock (which controls about $10 trillion in assets) has announced it is taking all active investments out of the thermal coal industry. Mining companies such as Rio Tinto, Fortescue Metals and BHP are shifting to renewable energy for their mining processes.

However, Prof. Moss wonders if this change will occur in a way that is timely enough to avert disaster.

“It seems to me that’s not the case at the moment.”

He says manufacturers or small business might be able to transition to renewable energy, but he is not sure if bigger companies will make the switch quickly enough.

Corporations such as BHP have committed $US400 million to deal with all the emissions that it produces.

However, he said the products that BHP produces would cause emissions greater than those emitted by 25 million Australians.

What can we learn from the government’s response to COVID-19?

Prof. Moss said the government framework has been crucial for what we do and cannot do but now we need to have a clear analogy with our response to climate change.

“We need a clear framework for all of our governments and in particular in relation to the supply of fossil fuels,” Prof. Moss says.

Professor Martina Linnenluecke from the Centre for Corporate Sustainability and Environmental Finance at Macquarie University says COVID-19 has made us realise just how much we must cut in terms of our own day-to-day trivial patterns to achieve emission cuts.

She says there already is momentum gathering to get us back to where we essentially were, without undertaking fundamental changes to the way that we globally operate.

Australians have been trained to see a political landscape that is very divisive and combative but Denise Shrivell, founder of Mediascope, which maps the Australia media and marketing landscape, says during the pandemic we have witnessed both sides of government work together with more unity.

“Hopefully, we'll see people start to reject that kind of combative politics on the other side of this and they'll want to see agreement, and they'll want to see evidence-based policy.”

Ms Shrivell says during COVID-19 society has been encouraged to pull together and to download the app but when faced with climate change “we’re a little more encouraged to be 'well … what can we do?' ”

She says it has been quite a significant difference in the way the government and the media are both trying to manage and sell both issues.

(AU) Australia Among Global 'Hot Spots' As Droughts Worsen In Warming World

Sydney Morning HeraldPeter Hannam

The world's major food baskets will experience more extreme droughts than previously forecast as greenhouse gases rise, with southern Australia among the worst-hit, climate projections show.

Scientists at the Australian National University and the University of NSW made the findings after running the latest generation of climate models used by the Intergovernmental Panel on Climate Change (IPCC). Future drought changes were larger and more consistent, the researchers found.

“Australia is one of the hot spots along with the Amazon and the Mediterranean, especially,” said Anna Ukkola, a research fellow at the ARC Centre of Excellence for Climate Extremes and lead author of the paper published in Geophysical Research Letters.

For southern Australia, the shift to longer, more frequent and more intense droughts up to 2100 will be due to greater variability in rainfall rather than a reduction in average rainfall. For the Amazon, both mean rain and variability changes.

The researchers applied the sixth generation of the so-called Coupled Model Intercomparison Project (CMIP6), which will underpin the IPCC's Sixth Assessment Report due for release in a series from April. The latest iteration benefited from five years more observations which were used for comparison and to refine processes.

The models simulated a so-called "middle of the road" scenario for greenhouse gas emissions against a high emissions "fossil-fuelled development" one. Under the latter trajectory, average droughts would double in length from two to four months by 2100 compared with the 1950-2014 period.

“For regions that have quite a lot of agriculture [such as North America and parts of China and Europe], the models suggest they will have more intense droughts in the future even though they may not experience changes in mean rainfall," Dr Ukkola said. “We don’t see any regions where intensity will decrease in the models."

One reason for the prediction of worse droughts is that the latest models assume the climate will respond more than previously understood to increased atmospheric levels of carbon dioxide and other greenhouse gases.

Some of the models used for CMIP6 predict changes of more than 7 degrees in global and Australian temperatures by the end of the century.

Australia's vulnerability to big shifts in annual rainfall already challenge the country's farming sector, while also leaving much of the country's south more at risk of bad bushfire seasons - such as last summer's - as forests dry out.

The CSIRO has long forecast a large reduction in stream flows in the Murray-Darling Basin, for instance, as reduced cool-season rainfall combines with higher temperatures. Such a trend appears to have already begun.

While a more moderate emissions trajectory will still produce more intense, frequent and longer lasting droughts in most of the world's mid-latitude regions than current conditions, the shift will be less than if carbon emissions remain near the top of forecasts.

"You are never every worse off with a 'middle-of-the road' course of emissions than a higher one," said Andy Pitman, director of the Climate Extremes centre, and one of the authors of the report.

"You are better off if you don't pump up the damn stuff in the first place," Professor Pitman said.
