Environment (Natural Disasters)

HR 4493, the Climate Health Emergency Act of 2025, requires the Secretary of Health and Human Services to declare a public health emergency specifically for climate-related health risks under existing law. This bill directly affects the federal public health system by mandating this emergency declaration, based on findings that climate change drives over half of recent public health emergencies (like extreme weather and disease spread). The key mechanism is the formal declaration under the Public Health Service Act, aiming to mobilize federal resources and improve coordination for climate-driven health threats. It focuses on addressing the growing health impacts linked to climate change, as identified in congressional findings.
