Acacia Pepler

Acacia Pepler is a PhD student at the University of New South Wales (UNSW) Climate Change Research Centre, where she studies extreme rainfall and East Coast Lows (ECLs), wild storms and their relation to climate change impacts.

Acacia Pepler initially began her career with an interest in Astronomy but her love of Science and Meteorology took over and after completing a Bachelor of Science BSc, she went on to become a PhD student, as she had always been interested also in the weather. So her current research work centres on the East Coast Lows perhaps as they are difficult to predict and can develop quickly.

As we all at times complain about weather forecast (but expect them to be accurate for a week ahead), our desire for an accurate prediction is of personal and probably superficial  nature or even can be a case of saving lives such as  with the Sydney to Hobart yacht race.  

Climate change can affect East Coast Lows in many ways, for example warmer days can make a cyclone more intense, more rising sea levels which are predicted to be about 1 - 1.5 metres (but NASA has predicted as high as 3 metres by 2050), influences by the Great Dividing Range which can intensify lows up and down the Eastern seaboard can also have an effect.  Answers to these questions are being modelled not only by the Bureau of Meteorology but the Universities of Macquarie and Newcastle, whose special study relates to history and dam levels in NSW the latter of which can be related to the important topic of water security.

Whatever the development of ocean warming intense rainfall is expected to  increase with each degree of global warming particularly when interacting with  cold air in the upper atmosphere.

Colin Seis - Farmers & Regenerative Agricultural

This show was broadcast on 17 November 2014

Col Seis Bio on Winona from Peter Hill on Vimeo.

Colin Seis is the inventor of the Regenerative Agricultural practice of Pasture Cropping. Col tells the story of the history of his family's farming enterprise from the 18 Hundreds to the present. His journey and experiences are documented, and how he came to the conclusion that it is critical for farmers to manage their native grasslands well, to achieve a goal of Profitable Regenerative Agriculture.

Beyond Zero Emissions recently released research - Land Use: Agriculture and Forestry - has found that the best part of half our greenhouse gas emissions come from land clearing, savannah burning and methane  from livestock. The discussion paper takes six farms as case studies of how to reduce or balance out these emissions by carbon sequestering plants, cell grazing and increasing soil richness. BZE Radio's Vivien Langford speaks to Colin Seis's farm Winona is at Gulgong NSW and he features in the report.
A shorter interview is with retired farmers Liz and Bruce Irvine who share with us their hard won insights once they stopped fighting with nature. The interviews cover many topics including the pioneering days, Aboriginal land management and the network of like minded farmers around the world who are leading the way with climate friendly practises.

Food Security and Hunger in a Warming World

In today's Community Show Podcast (broadcast on Mon 5 May 2014), we feature an edited version of a presentation at the annual 2014 Sustainable Living Festival in Melbourne.

Food Justice on a Hot Planet
Food security and hunger in a warming world

The world produces enough food to feed everybody. But one in eight people still go hungry & things are heating up. Crops are being parched then drenched. Companies are polluting & profiting & governments are letting it happen. For most of us, this means poorer quality food at an increasing cost. For nearly a billion people, it means more hunger.

Join an expert panel as they raise the big questions around the impacts of climate change on our broken food system & what we can do to fix it.

With Amanda McKenzie (The Climate Council), Peter Christoff (The University of Melbourne), Mohamed Riyas Rasheed (Oxfam Australia, Sri Lanka) and Shen Narayanasamy (Oxfam Australia).

Australia's Climate Action Summit & the media

Vivien presents a collection of interviews from Australia's Climate Action Summit 21- 23 June 2013, focusing on the role of the media. Guests include:

John Kaye, NSW Greens MLC,

Jane Rawson, Author and Energy and Environment Editor for the online journal, The Conversation. The difference with The Conversation is that it's written by academics, not journalists; it is not-for-profit and receives no advertising revenu. 

Larissa Waters, Qld Senator and environmental lawyer.

Climate Change and Australian Wildlife

Animal Planet - How Climate Change and Urbanisation are Affecting Australian Wildlife

Beyond Zero talks to experts from around the country about what is happening to Australia's native flora and fauna amidst rapid climate change and urbanisation.

Over the hour we delve into the forecast for 2030 in which Australian is hotter by more than a  degree. In such a world, the Mountain pygmy possum may cease to exist, due to the melting on Victoria’s Alps. Spotted Marsh Frog populations will rapidly decline from urbanisation and less rainfall, and we may have to prepare for the arrival of bats in our own backyards or the botanical gardens.

With such predictions in play we turn to the experts for help.

Beyond Zero's Sally Wilmott interviews Kate Philips, Senior Curator of Science Communication at the Melbourne Museum, PHD researcher Joab Wilson from the ARC Centre of Excellence for
Environmental Decisions and Michael Dunlop from the CSIRO. Beth Shepard then talks to Michael Kearney, Zoology academic at the University of Melbourne.

Local councils and climate solutions

Are councils getting things done in terms of climate solutions?
Are they more responsive to community pressures about climate change?

To find out BZE’s Vivien Langford goes to a ZERO Carbon house in Randwick NSW and meets Councillor Nicola Grieve at Rose Bay.

The Manager of Randwick Council’s Barrett House is Richard Wilson. He shows us how cheap double glazing and LED lights will cut down your bills. Terry Bail the architect tells us about the growing demand for sustainable houses. As we talk a working bee pops up in the vegetable garden so we
talk to Steve Batley about community and school gardens he’s guiding to fruitfulness. Russ Grayson explains how Sydney Council followed the lead of irrepressible guerrilla gardeners with a policy to help people grow food in the city without tripping up its citizens.

As council elections are in the air Vivien meets Councillor Nicola Grieve to talk about waste management, low carbon incentives, bike paths and cutting down the carbon miles for food. It’s not easy, as some councillors are climate change deniers and many in the community are switched off.

Zero Carbon Australia (ZCA) 2020 Land Use plan program

Bushfires, black soot, glaciers, deforestation. How do they affect the climate and what are the solutions?
BZE guest programmer Andrew Longmire interviews Dr Chris Taylor who is a Melbourne University researcher for the Zero Carbon Australia (ZCA) 2020 Land Use plan.

Steve Katsineris from Hurstbridge talks about ways to support biodiversity

BZE's Vivien Langford speaks to Steve Katsineris, a writer from Hurstbridge. They discuss the importance of protecting green wedges from development in order to support biodiversity.
