Water: Climate Change and Water

Pacific Islands Climate Change and Water

The primary climate-related concerns of the Pacific Islands region include availability of freshwater, adverse impacts to coastal and marine ecosystems, and exposure to hazards, including sea level rise and inundation. For more information about the overall impacts of climate change on the Pacific islands, in addition to water impacts, visit EPA's main climate change website.

Highlights of EPA and Partner Activities

The Pacific Island Climate Change Cooperative Exit EPA Disclaimer provides a range of scientific and technical tools to help managers in Hawaii, the Mariana Islands, American Samoa, and other Pacific Island groups make informed decisions for landscape-scale conservation of natural and cultural resources. The tools include climate models at the archipelagic and island scales; ecological response models; and implementation and monitoring strategies for island species, resources, and communities.

The Pacific Regional Integrated Sciences and Assessments Program Exit EPA Disclaimer supports Pacific Island and coastal communities in mitigating and adapting to the impacts of climate variability and change.

Climate and Water Strategy
Our Goals:

EPA programs in Pacific Islands will work to mitigate sea level rise impacts through infrastructure design and updates, prepare the public through disaster planning and education, and protect vulnerable ecosystems.

To learn more about the goals and strategic actions at the regional level, read the EPA water program’s 2012 Strategy: Response to Climate Change.

EPA Regions in the Pacific Islands
