Adapting to Change: How Biology, Society, and Environment Interconnect in Australia’s Evolving Climate

Australia is a land of stunning beauty and rich biodiversity. However, we’re facing a new reality. Extreme weather events like bushfires, flooding, and heatwaves are becoming the norm. These events don’t just disrupt our lives; they also take a toll on our health. Climate change is not something to worry about in the distant future; it’s affecting us now.

Experts highlight that as the climate warms, we can expect even more severe weather events. Heat, in particular, is a growing concern. It directly impacts mortality and overall health. The challenge for our health system—hospitals, doctors, and public health agencies—is figuring out how to respond to these environmental changes.

A recent study published in the *MJA* assessed a program aimed at helping heart disease patients cope with extreme weather. While the results were disappointing, showing no improvement in hospital stay lengths, the study also noted potential for better outcomes with some modifications. This kind of research is vital in understanding health in the context of a changing environment.

Health experts have long used a biopsychosocial model to understand illness. Yet, as climate change becomes more pronounced, we must adapt this model. Factors like temperature changes and air quality are crucial and can’t be ignored. The World Health Organization labels climate change as one of the biggest health threats we face today. Understanding these environmental impacts is complex but essential.

Imagine a biology–society–environment model. This model adds layers that can help us understand health better. For instance, factors like genetics and socioeconomic status influence health, but so does our environment—air pollution and extreme weather can worsen conditions like cardiovascular disease. By considering these three layers together, we can spot opportunities to reduce health risks.

Key environmental elements—air, water, and food—play critical roles in our health. Where we live can make a significant difference in how we respond to climate change. Incorporating these layers into health research helps us create effective interventions that protect us as our climate evolves.

The rise in extreme weather affects everyone, from children to the elderly, across all medical specialties. Acknowledging the relationship between our health and our environment is crucial. By using a biology, society, and environment approach in healthcare, we can better safeguard our well-being in this challenging era.

Ultimately, as we navigate these complex changes, it’s essential that medical research includes the significant environmental factors that can improve health outcomes. In doing so, we prepare ourselves to face a future shaped by climate change.
