Extreme weather events and ecosystem changes are increasing with climate change. The health consequences of these events are significant. The environmental hazards of concern span a wide range: extreme temperatures, storms, aeroallergens, wildfire, and drought. This session invites presentations on the economic valuation of the health impacts associated with these hazards. Beyond estimation of risks and impacts, the session also welcomes presentations on the economic cost and effectiveness of interventions aimed to reduce the health impacts. The presentations can be related to, but not restricted to, health costs to healthcare systems and individuals, health insurance implications associated with extreme weather events, and implications of these extreme events on economic and social equity.
