It is difficult right now to contemplate issues other than battling COVID-19. However, we must not lose sight of another worldwide crisis that, unless we confront it head-on, will be with us long after the pandemic is behind us. That crisis is climate change. Increased susceptibility to pandemics is likely to be a consequence of it. Unlike pandemics, climate change poses an even more long-term and pervasive existential threat to both our mental and physical health, and our existences. Many more of us who live in Australia now fear that climate change is upon us and here to stay.

Droughts, no stranger to Australians, often are punctuated by dramatic floods, and we are now dealing with extended summer seasons filled with bushfires. We are experienced in managing them. These fires are usually limited to a few different states, so fire crews typically help one another out as they are controlled and extinguished. Australians pull together with great community spirit and resilience under these circumstances.
But the last two fire seasons have been different. They have become unseasonably long, more severe, and often uncontrollable and overwhelming. We have experienced two uncharacteristically prolonged droughts, more recently creeping across most of our continent. Last spring, wild fires took hold very early and were ubiquitous, increasing during the unusually high summer heat. Climate change already had worsened our accustomed pattern of droughts, fires, and floods.
Meanwhile, the Australian federal government repeatedly ignored advice from highly respected meteorological, environmental, scientific, and economic experts.1
Warnings from experts
The state fire commissioners had formally warned our government of increasing vulnerability via climate change to bushfires. This occurred in the context of government inaction, lack of national investment (for example, insufficient water bombing equipment), and the absence of national preparation for the predicted catastrophic fire season. Prime Minister Scott Morrison declined to meet with them, minimizing the role of climate change. He provided no extra resources, emphatically leaving the responsibility to state governments.2
Distinguished economist Ross Garnaut concluded that Australia could lead the world in renewable energy production and harness it for industries and employment, if only the government chose to invest in our ample renewable sources. Sadly, our conservative government and its corporate sponsors maintain an addiction to fossil fuels, arguing that they protect employment. Meanwhile, the economic “trickle-down” benefit from massive coal and gas exports has been illusory. Socioeconomic inequities have widened, with profits favoring the mega-rich, while mining automation takes jobs.
With the fire emergency crisis at its height, Mr. Morrison sent his energy minister to the U.N. Madrid Climate Change Conference with the goal of preventing meaningful CO2 reductions, in collaboration with Brazil, Saudi Arabia, and the United States.

The sustained drought and desiccated vegetation, the escalating fuel load growth, and early hot weather led to super-hot fires, with catapulted ember attacks and fireballs falling from the sky, which burned down thousands of homes and incinerated livestock. The fires led to numerous human fatalities and overloaded hospital burn units. The unprecedented fire season duration and uncontrollable fires exhausted voluntary fire crews. There have even been fires in cool damp rain forests – the usual refuge/reservoir of endangered flora and fauna species.
The simultaneous droughts, unusual heat, and pervasive smoke also badly affect major cities, and intense fires terrorized the entire nation. Consequently, regional firefighting teams were unable to help other regions. Huge, unquenchable fires created spiraling micro-weather systems, with thunderstorms spitting dry lightning, sparking new fires and twisters, tornadoes, and updrafts hurtling heavy fire trucks into the air, which caused terrible injuries and death to fire crews. Ultimately, the federal government had to supply large-scale sea and air evacuations, and call up military reservists for civic duties.
