We must prepare entire cities for extreme heat. Our new study reveals how
In Australia, the days are growing longer and summer is fast approaching. But a very strong El Niño—a natural weather phenomenon that drives variations in temperature and winds across the Pacific—could make this summer a sweltering one.
Australia's summer is expected to become increasingly hot, with a strong El Niño phenomenon potentially leading to extreme temperatures. The Greater Sydney region is taking steps to prepare for these rising temperatures. A new study reveals that Western Sydney, known for its extreme heat, needs a city-wide approach that goes beyond basic advice like drinking water and staying indoors.
While many Australians know how to cope with heat, not everyone can afford air conditioning, have well-insulated homes, or have strong connections to their community. The Greater Sydney Heat Taskforce, established in 2023, aims to protect vulnerable populations, including the elderly, pregnant women, and those with health conditions.
The taskforce, led by the Western Sydney Regional Organisation of Councils and Resilient Sydney, brought together representatives from various sectors to develop the Greater Sydney Heat Smart City Plan. This plan, launched in December 2024, includes 40 recommendations for action between 2025 and 2030, addressing issues like raising awareness, designing cooler neighborhoods, and protecting vulnerable communities.
The plan also emphasizes the need for better coordination of services and emergency responses. The researchers found that coordination is key to creating an effective heat plan, as siloed organizations often lead to fragmented responses. Community involvement is also crucial, with initiatives like Sweltering Cities and the Western Sydney Community Forum boosting support for heat awareness and preparedness.
However, long-term funding, clear responsibilities, and ongoing support from local institutions are essential for the success of any city-wide heat plan. The NSW government is exploring ways to incorporate urban greening and heat-sensitive building design into planning through a draft State Environmental Planning Policy. While promising initiatives exist, turning these into practical, lasting changes across government and industry remains a challenge.
