The recent MJA-Lancet Countdown report reveals a troubling rise in dangerous heat exposure in Australia. Over the last 20 years, this increase has reached 37%. Alarmingly, Australia now holds the position of having the second-highest number of climate change cases in the world.
According to lead author Professor Paul Beggs from Macquarie University, the frequency of health-threatening heat has "substantially" grown since the 1970s. This trend has raised serious concerns, particularly regarding vulnerable populations. Beggs pointed out that health issues have been a focal point in eleven Australian climate cases from 2014 to 2023, showing a clear connection between climate change and public health.
The Countdown report, which first appeared in 2017, provides an annual look at how health and climate change intersect in Australia and New Zealand. It addresses various areas including health hazards, adaptation strategies, and public engagement.
Statistics suggest that in 2021, Australia’s healthcare sector emitted greenhouse gases at its highest level in a decade. This surge is partly linked to changes in care patterns during the COVID-19 pandemic, highlighting how health responses can affect environmental outcomes.
The report also flagged concerning trends beyond rising heat. There’s been a 17% decrease in volunteer firefighters over the last seven years, impacting Australia’s capacity to respond to bushfires. Meanwhile, fossil fuels continue to dominate the energy supply, exacerbating climate risks.
Professor Hilary Bambrick from ANU praised recent government initiatives like the national climate risk assessment. This initiative aims to better understand and manage risks linked to climate change, ultimately protecting public health.
On a positive note, the assessment highlighted Australia’s shift towards renewable energy, with nearly 40% of electricity now coming from renewable sources. Growth in both large-scale and small-scale renewable energy is encouraging. However, Professor Stefan Trueck from Macquarie University warns that more investment is needed to fully realize the potential of renewables. He stated, "While renewable electricity generation is growing, ensuring a dependable supply requires increased investment in both renewables and energy storage."
This Countdown report illustrates critical challenges and strides Australia faces in tackling climate change and its effects on health. The findings emphasize the need for continuous monitoring and action to safeguard both environmental and public health moving forward.
