After hours webinar series about climate and health

After Hours Webinars

After Hours is a webinar series all about climate change and human health, facilitated by Dr Kate Wylie. Each session focuses on one specific aspect of the relationship between climate change and human health—and what the public and health professionals can be doing about it.

Episodes are delivered by a leading health expert in the relevant field. Joining the live audience is free and all are welcome. Recordings of each session are available on this page and our YouTube Channel.

If you’re a doctor, After Hours sessions are CPD accredited by the RACGP and ACRRM and can be submitted as self directed learning for most other colleges. Attendants of the webinars will be provided with a certificate of attendance on request. 

Dr Kate Wylie

About Dr Kate Wylie

Kate is a GP and the executive director of DEA. Her passion about the need for climate action to protect health is evident in her extensive involvement in climate and health advocacy. She is the immediate past chair of DEA and of the RACGP's Climate and Environmental Special Interest Group. She has founded Climate Medicine, an advocacy project whereby she presents to community groups on the health effects of climate change.

In all her work, Dr Wylie seeks to activate her audience so they can become more involved in creating the paradigm shift that we need to combat the climate crisis and ensure the health of our beautiful planet.

“Our planet is worth saving, and so are we.”


Fossil Fuels are a Health Hazard

Coal, oil and gas damage our health in multiple ways. 

These fossil fuels are the primary drivers of climate change and its multiple health impacts and cause air pollution contributing to 1 in 5 deaths globally per year. If that's not bad enough, fossil fuels are also the source material for plastics, which are clogging our oceans and our arteries. 

Getting out of dirty unhealthy fossil fuels is critical for the health of our planet and the health of Australians.

This webinar will look at these health harms and then outline a treatment plan for how we can protect our own health and that of our planet from this extreme health hazard.

Facilitated by our ED Dr Kate Wylie, our speakers for the webinar are:

  • Dr Aditya Vyas: Associate Professor of Public Health & Deputy Director of the Healthy Environments And Lives (HEAL) Global Research Centre at the University of Canberra. Adi will provide an overview of the health impacts of climate change.
  • Dr Louse Woodward: Paediatrician from Royal Darwin Hospital. Louise will outline the impacts of pollution from gas extraction and petrochemical processing with a particular focus on the proposed Middle Arm development.
  • Dr Mitchell Hickson: Physician at NSW health who will look at the emerging evidence of the impacts of plastics on our health, particularly on endocrine disruption and infertility.

Lastly, Dr Wylie will look at how we can treat these health problems and discuss with the panel ways that we can work together to make a difference.

Create a safe path to a safe earth

As the world enters an era of climate and ecological crisis, it is time for a historic re-imaging of how we think about and approach security. What could an emergency whole-of-society mobilisation look like? What if we decided to go for it? How do we prepare? This talk introduces PLAN E – a concept for a HyperResponse to the hyperthreat of the climate and ecological crisis. PLAN E involves new language, new concepts, and new security logic to help humanity recalibrate, reorientate, and reclaim our future. These ideas can inform the medical sector’s strategic planning for planetary crisis.

Presented by Dr Elizabeth (Liz) G. Boulton whose doctorate work developed Plan E: A Grand Strategy for the Twenty-first Century Era of Entangled Security and Hyperthreats. This is the world’s first climate and eco-centred security strategy and was published by the US Marine Corp University Press in 2022. More information is on her website at

Trees are Tremendous

Trees should be celebrated for all that they give us as humans and for their integral part in global biodiversity and planetary support. Not only are trees beautiful they also:-

  • Boost our physical and mental health 
  • Filter our air and water  
  • Provide homes for pollinators, that underpin much of our food supplies
  • Cool our communities
  • Help protect us from infectious diseases  
  • Connect to Country
  • Help curb climate change- the biggest threat to health this century. 

But these incredible things need our protection. Australia is a deforestation hotspot, and this directly harms our health and damages our natural world. 

Our expert panelist are:

Dr Marion Carey, public health physician and co-author of Trees the forgotten heroes of our health Report Ms Sarah Dawson, Engagement Manager at WWF-Australia, working on their Towards Two Billion Trees Campaign; Dr Jennifer Sanger, a passionate forest ecologist and science outreach coordinator, co-founder for The Tree Projects; and Dr Jenny Conway, rural specialist GP and proud secretary of her local Environment group in the Yarra Valley. She will share DEAs End Native Forest Logging in Australia position statement.

Fracking with our Health - the health impacts of gas extraction

Fracking and other forms of gas extraction are known to have multiple detrimental impacts on human health. There are direct impacts from the process itself, like air and water pollution, and gas also contributes to global warming and the climate crisis, which is the greatest health threat facing humanity.

Despite this, Gas is big business in Australia. Australia is the largest exporter of LNG in the world and the industry continues to expand into new territory like the Beetaloo Basin and the Scarborough Gas field.

This webinar looks at the many serious effects of gas on human health. 

Our expert panelists are: 

Professor Melissa Haswell, Professor of Practice in Environmental Wellbeing at the Sydney Uni, Portfolio of the Deputy Vice Chancellor, Indigenous Strategy and Services and School of Geosciences at University of Sydney; Mr Jacob Hegedus, Research Assistant, Deputy Vice Chancellor, Indigenous Strategy and Services at Sydney Uni and Gumbaygnnirr man from the Northern Rivers whose community fought against fracking of their land and won; and Dr Arnagretta Hunter, Human Futures Fellow ANU College Health and Medicine.

Nature, Our Medicine

The natural world provides our life support system- giving us clean air and water, a stable climate and healthy soils to grow our food. Earth’s biological richness, or biodiversity, offers us precious medicines and beautiful places for psychological and spiritual rejuvenation. Yet modern life has seen screen spaces replace green places as we have moved inside and into virtual worlds. This change has not been good for us, or our planet. Lifestyle-related diseases and mental health problems are overwhelming health systems everywhere. Meanwhile, outside, the natural world is falling apart with climate change and mass extinctions of plants and animals. The solution is simple: we need to reconnect to nature.

Join mother, nature lover and GP, Dr Dimity Williams, as she discusses her new book, Nature, Our Medicine: How the natural world sustains us. 

Incorporating science, history, stories, and alternative cultural knowledge, Dr Williams makes the case that caring for nature is essential for our wellbeing. And for all life on Earth. With a Foreword by Bob Brown, her book provides an accessible exploration of the link between human health and the natural world.

Biodiversity: A necessity for human health

Fifty years ago the United Nations held the first conference to focus on the importance of the environment. The associated ‘Stockholm Declaration’ led, amongst other things, to what has become the global sustainable development agenda. In that same year, the late Melbourne GP turned politician, Dr Moss Cass, was appointed as our first Australian Minister of the Environment and Conservation. These two events were seminal in framing the current global and national environmental and conservation laws and regulatory frameworks. 

Despite these and further initiatives by subsequent advocates, we face a relentless crisis in the state of Australian and global biodiversity.

The 2021 State of the Environment report outlines the sorry state for our country. The current Biodiversity COP15 in Montreal reflects the global efforts to protect biodiversity and avoid mass global extinction.

Presented by Associate Professor Ken Winkel, Biodiversity: a necessity for human health will consider the state of biodiversity, its bi-directional links to human health and steps doctors can take to reverse this threat to planetary health.
