How does climate change affect health worldwide?
Climate change leads to more frequent and severe heatwaves, which can cause heat-related illnesses and deaths. It also increases the spread of vector-borne diseases like malaria and dengue, as warmer temperatures expand the habitats of mosquitoes. Additionally, extreme weather events such as floods and wildfires can damage healthcare infrastructure and disrupt access to medical services, putting global health at risk.

Who are the most vulnerable populations affected by climate change?
Older adults, children, low-income communities, and those with pre-existing health conditions are most vulnerable to the impacts of climate change. For example, elderly populations are disproportionately affected by heatwaves, while low-income groups often live in areas more exposed to environmental hazards like flooding and pollution. These groups typically have fewer resources to adapt or recover from climate-related health issues.

What measures are being taken globally to adapt to climate change?
Countries are implementing various strategies such as expanding green spaces in cities to reduce heat, improving early warning systems for extreme weather, and investing in resilient healthcare infrastructure. International organizations promote climate adaptation policies, including better urban planning, disaster preparedness, and community-based programs to protect vulnerable populations from climate-related health risks.

How do wildfires and heatwaves threaten communities?
Wildfires and heatwaves pose immediate dangers by causing injuries, fatalities, and respiratory problems due to smoke inhalation. They also strain emergency services and healthcare systems, especially in urban areas with dense populations. Long-term effects include mental health issues and displacement, as communities face destruction of homes and livelihoods, emphasizing the urgent need for effective mitigation and adaptation strategies.

What is the link between urban infrastructure and heat-related health risks?
Urban areas with extensive concrete and asphalt surfaces tend to trap heat, creating 'urban heat islands' that intensify heatwaves. This increases the risk of heatstroke and dehydration, especially among vulnerable populations. Expanding green and blue spaces, such as parks and water bodies, can help cool cities and reduce health risks associated with extreme heat.

Why is climate change considered a public health emergency?
Climate change exacerbates existing health inequalities and introduces new health threats, making it a pressing public health issue. The World Health Organization and other agencies warn that without urgent action, climate-related health impacts will continue to grow, overwhelming healthcare systems and increasing preventable deaths worldwide. Recognizing it as an emergency underscores the need for immediate, coordinated responses.
