A note on COVID-19

Over the last weeks and months, our world has changed dramatically. We're in the midst of a global pandemic, which requires strong, collective action to protect people's health by slowing the spread of COVID-19 to prevent our health system from being overwhelmed.

There are encouraging initial indicators that here in Australia, our response measures are having a positive effect. But experts warn there is still a long way to go. Our health system is preparing for the worst, with many health professionals working tirelessly on the frontline. 

Responding to COVID-19 has required shutting down large parts of the economy, with the potential for hundreds of thousands of people to lose their jobs and many small businesses and organisations facing uncertain futures. While the government has announced significant support packages for certain people, businesses and industries, civil society and unions are hard at work to ensure no-one is left behind. CAHA is part of conversations with other organisations like Climate Action Network Australia and Centre for Policy Development on how we can shape the policy agenda going forward - to ensure a healthier, safer, fairer, more sustainable future for all.

While it feels difficult to talk about other issues during this uncertain time, it is important that we continue our fight for urgent action on climate change.

COVID-19, environment and climate change

Many people may be wondering how to address the climate crisis at the moment, without adding anxiety or removing focus. This interview with Courtney Howard, an emergency physician from Canada discusses just that:

"if we come in with a climate crisis narrative at this moment, people just won’t have the energy to cope with it. And we always need to be respectful of where people are at. But the coronavirus has underlined that we’re all in this together, and that a lack of attention to the interface between humans and the natural world puts us at immense risk..."

Coronavirus is a wake-up call: our war with the environment is leading to pandemics

CAHA Executive Director, Fiona Armstrong, has written for the Conversation with Professor Tony Capon Director, Monash Sustainable Development Institute and Dr Ro McFarlane from University of Canberra this week on how the COVID-19 crisis and the climate and biodiversity crises are deeply connected.

They write: "the health, social and economic consequences of COVID-19 should act as a wake-up call for all governments to take stock, carefully consider the evidence, and ensure post COVID-19 responses reverse our war on nature. Because – as pioneering 20th century conservationist Rachel Carson argued – a war on nature is ultimately a war against ourselves."

How are climate change and COVID-19 linked?

Josh Karliner from Health Care Without Harm writes in Medium about the ways in which climate change and coronavirus are linked, and how coronavirus is highlighting the areas of society and our health care system which will be most strongly impacted by the climate crisis. This is a long read, covering many important points including air pollution, migratory viruses, climate refugees and health inequity. Read the full piece here.

Carbon emissions in the time of a pandemic

Much as been reported on temporary decreases in carbon emissions across the globe, from decreased manufacturing to an almost complete halt of the airline industry. "The numbers offer a sobering reminder of how deeply the modern economy still depends on fossil fuels" writes the New York Times. While this may be positive, it is important to consider the livelihoods impacted by industries shutting down, and the need to support people through the transition to clean energy. Similarly, it is unlikely these impacts will lead to the long-term behaviour change required to fight climate change.

What can the coronavirus pandemic teach us about tackling climate change?

The response to the coronavirus pandemic has been swift, and has had many economic impacts. But what can be learned from the current pandemic to help us fight climate change? A/Prof Natasha Chassagne from the University of Tasmania outlines some key points. Read more here.

Similarly, this article in Yale Environment 360 argues that we must focus on preventing problems rather than fixing them, with the response to COVID-19 showing "that if you wait until you can see the impact, it is too late to stop it.". Read more here.


Every child's future is under threat from climate change

No one country is doing enough to protect children's health and well-being in the face of climate change, a new report from WHO, UNICEF and The Lancet says. Progress on the health of children and adolescents has improved in recent decades, but is now stalling and not enough is being done to ensure they have a safe future in a world of environmental uncertainty. As Australia is one of the top ten emitters of carbon worldwide, "Australia is squandering its opportunities to secure a safe and healthy future for our children" says Dr Liz Hanna from ANURead more here.

Unprecedented smoke-related health burden from the 2019-2020 Australian bushfires

Researchers from University of Tasmania and Centre for Air Pollution, Energy and Health Research have revealed poor air quality associated with smoke from Australia's recent bushfires contributed to more than 400 deaths, and more than 4000 hospital presentations for cardiovascular conditions, asthma and other respiratory conditions. The authors estimate more than 80% of Australia's population was impacted by the bushfires. Read the full report here, and more about the research here.

Healthy Futures: ask HESTA to divest

Around 400 doctors led by CAHA member Healthy Futures have called on super fund HESTA to divest from fossil fuel investments. HESTA's members largely work within the health sector, however, HESTA continues to invest in large fossil fuel companies. HESTA has previously divested from the tobacco industry thanks to community lobbying, setting a precedent for divestment from industries that cause harm to health. HESTA has so far declined to comment on protests and ignored a request to meet with Healthy Futures. Read more here.

Health impacts of extreme heat & heatwaves

Extreme heat and premature births

Extreme heat impacts many populations in society. For pregnant women, exposure to extreme temperatures can lead to an increase in premature deaths and low birth rate. In some parts of Africa, the impacts are potentially more extreme due to the high percentage of women who participate in subsistence farming. A study by the London School of Hygiene and Tropical Medicine is aiming to understand how this combination of extreme heat exposure and manual labour can impact pregnant women and infants. Read more here.

Heatwaves mean more deaths from injury

A US study has shown an increase in average temperatures of 1.5 degrees Celsius would lead to 1,600 more deaths annually across the US. This includes deaths from drowning, falls, transport accidents and intentional deaths from assault and suicide. Given Australia is on course for an even greater increase in average temperatures, we could see even more deaths. Read more here.

Older people face the highest health risks from heatwaves

Humans keep cool in extreme heat by perspiring; when sweat evaporates, it cools us down. However, for elderly people this important mechanism is impeded. Older adults cannot produce sweat in the same way as younger adults, and don't have the same ability to cool down. Extreme heat can exacerbate existing conditions such as heart and kidney disease, and lead to delirium and confusion for some older adults. Read more here. 

Climate change - on the frontline in Australia

In case you've missed it, The Guardian Australia has presented a series focusing on the impacts that the climate emergency is having across Australia. From crop growth and food security, to hazardous air pollution and killer heatwaves, the series interviews people from across Australia being impacted by the climate crisis right now. Take a look at the full series here.

Locust swarms and climate change

Many African nations have been suffering from outbreaks of desert locusts in 2020, the worst seen in years. These swarms of locusts have been caused by higher temperatures and above average rainfall linked to climate change. The large swarms of locusts pose a considerable threat to food security in vulnerable African nations. Read more here. 

Plant-based diets fight more than just climate change

It is likely not news to CAHA readers that plant-based diets are a great way for individuals to reduce their carbon footprint. Plant-based protein sources such as beans have a carbon cost of 20 times less per gram than beef, and sustainable land practices and rotating crops help to keep carbon in the ground as well as restore ecosystems. But plant-based diets are beneficial for more than just the environment, they can help to tackle a variety of chronic diseases and even improve mental health. Read more here.

Access to reproductive health vital to fighting climate change

Globally, millions of women lack access to effective contraception due to policies, stigma and cost. Many women have unintended pregnancies and are left without access to essential maternal and newborn healthcare. A new report by Project Drawdown has identified that providing girls with access to education and empowering them with a choice about when they want to start a family decreases fertility rates. This leads to improved health outcomes, as well as reduced per capita carbon emissions. Back in 2009 The Lancet discussed the need to improve global access to family planning. It is clear that much more progress is required. Read more here.


Climate change is a health emergency

Right now the world is responding to the public health emergency of the COVID-19 pandemic. Yet just months ago, millions of Australians were subjected to unprecedented climate-fueled bushfires and dangerous levels of air pollution from bushfire smoke, resulting in hundreds of people dying. 

While we are appropriately focused on the COVID-19 pandemic, when the crisis eases we must be ready to continue the momentum for strong, collective action to protect our health from the climate emergency. 

We're calling on our elected representatives to act on climate to protect our health. Please join us by signing the petition.

Clearing the air - sign & spread the word!

This year, Australian Environment Ministers will decide on new air pollution standards for three dangerous pollutants connected to the burning of fossil fuels: nitrogen dioxide, sulfur dioxide and ozone. These pollutants have harmful effects on people’s health - even at levels well below Australia’s current standards.

We need strong, health-based air pollution standards to reduce the harm to health, and accelerate the transition from dirty fossil fuels to clean, safer energy sources.

Will you sign the petition asking all Australian Environment Ministers to cut air pollution and protect our climate and our health by supporting stronger standards?

Research and Reports

Climate adaptation for the health and wellbeing sector in Queensland

A new article published in Environmental Science and Policy by Fahim Tonmoy, Sue Cooke, Fiona Armstrong and David Rissik describes the development of the Qld Human Health and Wellbeing Climate Adaptation Plan (H-CAP), part of the Queensland Climate Adaptation Strategy. CAHA played a lead role in the development of the H-CAP which provides direction for climate change adaptation planning and implementation within the health and wellbeing sectors. Read the full paper here.

The gendered impact of the COVID-19 pandemic

A letter published in The Lancet by researchers in the Gender and COVID-19 Working Group highlights the importance in acknowledging the differing impacts of the current global pandemic on gender. Women are frequently disproportionately impacted by these types of events, as women are frequently care givers and a large proportion of healthcare workers are women, putting them at higher risk of infection. This article highlights the importance of incorporating sex and gender effects into our understanding of global events, and acts as a reminder of the gendered impacts of climate change. Read the full letter here.

A future for the world’s children? A WHO-UNICEF-Lancet Commission

This joint report by WHO, UNICEF and The Lancet finds all children globally are at risk of the impacts of climate change, ecological degradation and migration. The report discusses inherent inequalities in our global system, where children from wealthier countries have better health outcomes, but high per capita emissions which threatens the health of all children worldwide - and disproportionately impacts those in lower income countries.

This report argues that children's health and well-being must be put at the centre of decision making and in achieving the Sustainable Development Goals.

The report calls on all sectors, not just health and education, to put children first in improving living conditions through reducing environmental pollution, increasing active transport opportunities and introducing clean energy.

"The effort required is enormous, but if we cannot deliver for our children, what is the measure of our civilisation?" Read the full report here.

Our Future on Earth, 2020

A new report by Future Earth aims to understand and define the current state of the planet across various sectors including politics, biodiversity, the media and food and the challenges faced by humanity in each of these. 

This beautifully presented report covers all areas of the climate crisis and the state of the planet in 2020, from the health impacts of climate change, to grassroots movements, financial impacts, displaced peoples, single-use plastics and the spread of disinformation.
