Australia has just recorded itshottest November on record, only months after the devastating bushfires of last summer that ruined the lives and livelihoods of thousands.

Climate change is doing its deadly work. Australia is alreadyabout 1.5 warmer than it was 100 years ago, and there is worse to come.

As our continent continues to warm, we will have to endure harsher heatwaves and more severe storms. The cyclones in our far north will be more intense, causing floods that will destroy homes, businesses and lives.

Health authorities need to do more. The federal health departmentsays its vision is better health and wellbeing for all Australians, now and for future generations. Yet there is little mention of the greatest health risk facing our future generations: climate change.

Currently, what the World Health Organisationcallsone of the worlds greatest health risks doesnt rate a mention in AustraliasLong Term National Health Plan, or the Department of Healths forward-lookingCorporate Plan.

The departments A$5 billion investment plan for theMedical Research Future Funddescribes 20 funding initiatives for the next decade and identifies areas of national priority. But it doesnt once mention climate change.

Why the silence?

At the national level, there is an evident unwillingness to speak about the damage climate change is already doing to Australians health. And things are only going to get worse.

TheGrattan Institute has today released a reportthat identifies ways the health sector should adapt to the changing climate in Australia.

The coronavirus pandemic provides a model. Australias response to COVID-19 was led by a national cabinet and informed by the national and state chief medical and health officers, meeting as theAustralian Health Protection Principal Committee (AHPPC).

Our political leaders listened to the science presented by these expert advisers. They used this evidence and advice to make unprecedented decisions in unprecedented times to protect the lives and livelihoods of millions of Australians.

They must do the same with climate change. Governments should establish a climate change and health subcommittee of the AHPPC, tasked with generating research and providing advice on climate change adaption and mitigation.

The new subcommittee should incorporate research that touches on climate change and is already done by existing committees such as the Communicable Diseases Network Australia, the Environmental Health Standing Committee, and the National Health Emergency Standing Committee. Officials on the climate change and health subcommittee should meet regularly, share strategies, and encourage coordinated and consistent national action where appropriate.

Time to step up

More must be done at the national level. The Commonwealth Department of Health must add the health risks posed by climate change to its priority list. Climate change should feature prominently in its Long Term National Health Plan and in its National Preventive Health Strategy, currently in development, to ensure proper resources are made available.

All governments should ensure the health sector incorporates climate change into risk assessments and disaster planning. This could be done by mandating a new requirement in theNational Safety and Quality Health Service Standardsfor health services to assess climate change risks.

With the worlds sixth-largest landmass spanning a wide variety of climates, Australia faces a unique combination of climate-related health challenges. Our research institutions must get more support to pursue climate-health knowledge. Between 2013 and 2020, the National Health and Medical Research Council (NHMRC) awarded less than A$2 million out of A$6.3 billion to climate-and-health research topics just 0.03% of the total.

After years of little interest, the NHMRC has just announcedA$10 million in dedicated fundingto improve Australias preparedness and responsiveness to human health threats from changing environmental conditions and extreme weather events, to begin in 2021. This is a step in the right direction, but Australia will need to provide much more support for climate change and health research.

The Medical Research Future Fund investment plan should have a dedicated focus on climate change and health research, so Australias researchers can help us all better understand our problem.

In the coming years and decades, Australias climate will become more dangerous and destructive. In 2020, with strong leadership and evidence-based decision-making, Australia had remarkable success in confronting the challenges of COVID-19. Now we must do it again on climate change.
