United by the values of equity, justice, and Aloha, the Hawaiʻi Climate Change and Health Working Group collaborates across disciplines and communities to strengthen Hawaiʻi’s public health resiliency in response to our changing climate.Using a data-driven approach, our mission is to research and communicate the human health impacts of climate change and to advocate for policy solutions that prioritize our most at-risk community members.
Climate change is already affecting Hawaiʻi, which is particularly vulnerable due to its mid-Pacific location. Effects include higher temperatures and sea levels, altered rainfall patterns, more frequent and intense storms, wildfires, coastal erosion, loss of biodiversity, and ocean acidification. These changes threaten food and water security, marine ecosystems, air quality, coastal communities, disaster response capabilities, cultural ties to ʻāina, agriculture, tourism, and overall health, with some communities experiencing disproportionate effects. Explore the resources below to learn how climate change is affecting public health in Hawaiʻi and what the State is doing to protect our communities.
