Canberra's pristine image masks a growing health crisis fuelled by climate change.

Bushfire smoke from the 2019-20 season alone caused 31 excess deaths in the ACT, alongside over 200 hospitalisations for cardiovascular and respiratory issues.¹

Projections warn of up to 40 days above 35°C annually, with severe heatwaves reaching 44°C for 10 days, overwhelming hospitals.²

Eco-anxiety surges among youth, blending acute stress from fires and floods with chronic hopelessness about the future.³

Emergency departments see spikes in mental health presentations during extreme weather, as services strain under shorter recovery windows.⁴

Vulnerable outer suburbs like Tuggeranong lack tree cover, exacerbating risks for elderly and low-income residents in inefficient homes.²

Respiratory illnesses from smoke inhalation fill wards, while cardiovascular events rise hours after pollution peaks.⁶

Mental health burdens deepen, with climate distress hitting regional youth hardest amid repeated disasters.³

Hospitals face disaster fatigue as bushfires, heatwaves, and storms strike with less respite.

Low-income households endure unsafe heat in energy-poor dwellings, amplifying inequities.⁵

Physical Health Under Siege

The 2019-20 bushfires blanketed Canberra in hazardous smoke for weeks.

This pollution triggered 31 premature deaths in the ACT.

Over 200 excess hospital admissions followed for heart and lung problems.¹

Emergency visits for asthma reached 89 cases linked to smoke.¹

PM2.5 particles from fires enter the bloodstream, sparking inflammation.

Sudden cardiac arrests spike 8-10 hours after exposure surges.⁶

97% of surveyed Canberrans reported physical symptoms like eye irritation and coughs.¹⁴

Climate-driven longer fire seasons promise more such episodes.

Heatwaves compound risks, with rising temperatures hindering outdoor activity and exacerbating chronic conditions.⁷

Mental Health in Crisis

Eco-anxiety grips young Canberrans, manifesting as helplessness and hopelessness.

Regional youth link bushfires and floods directly to climate change, triggering acute stress.³

Disasters evoke depression over future prospects, clinicians note.

Over two-thirds of Australians aged 16-25 report climate-related distress.⁹

26% of ACT residents relived trauma during smoke events.¹¹

Extreme weather disrupts mental health services while demand soars.⁴

Youth feel dismissed by leaders, fuelling burnout among activists.¹³

Validation from professionals eases distress, yet access lags.

Healthcare Systems Overwhelmed

Hospitals in the ACT bore heavy loads from 2019-20 smoke.

Prolonged poor air quality amplified urban health burdens.⁶

Heatwaves drive mental health emergencies, presentations rising with temperature.⁴

Shrinking intervals between events breed disaster fatigue in staff.

Climate models predict inundated facilities from extreme heat alone.²

Emergency departments log more admissions during prolonged heat.¹⁷

Resource strains hinder recovery, threatening care quality.

Vulnerable Groups Exposed

Outer suburbs like West Belconnen and Tuggeranong top risk lists.

Scarce tree cover fails to buffer scorching heat.²

Elderly residents suffer most from heat exhaustion and dehydration.⁵

Low-income households crowd energy-inefficient rentals.

These dwellings trap heat, becoming hazardous in extremes.¹⁵

Socio-economic disadvantage correlates with poor cooling access.

First Nations people and renters face compounded risks.⁵

Without cars or air-conditioners, escape proves difficult.¹²
