Extreme heat poses significant risks to public health, infrastructure, and daily life. It disproportionately affects vulnerable populations, including children, the elderly, and low-income communities. High temperatures combined with humidity can lead to heat-related illnesses and fatalities, particularly in areas lacking adequate cooling systems. The guide highlights the need for policies to ensure safe indoor temperatures, affordable cooling options, and workplace protections. Additionally, extreme heat can strain critical infrastructure such as energy and water systems, increasing the risk of outages during heat waves. The agenda aims to mitigate these risks through proactive measures and community preparedness.
