The following Bulletins describe climate impacts observed in Alaska communities, that have the potential to effect public health. The Bulletins rely upon observations, data and traditional ecological knowledge provided by local partners. Additionally, environmental, climate, health and other scientific data is provided where available. The purpose of the Bulletins is to describe changes that are occurring in Alaskan communities so as to help in the development of adaptive strategies that encourage community health and resilience.

Climate Change Effects on Traditional Inupiat Food Cellars 

This paper reports on a special concern identified in Point Hope during a recent Climate Change Assessment: the thawing of traditional food storage cellars due to warming soil temperature. This phenomenon is reducing the quality and quantity of food available to residents of Point Hope. Climate change is a likely cause and adaptive strategies are necessary to restore food security for Point Hope and other communities that depend on traditional storage cellars.

Source Drinking Water Challenges, Changes to an Arctic Tundra Lake

Blooms of organic material have in the past been observed in the source water lake in Point Hope, but conditions have been extreme over the past two years. If warm temperatures continue, organic blooms will become a reoccurring problem for Point Hope and other communities that depend on tundra lakes for their drinking water supply. Analysis of source water chemistry and biology is recommended, as is an analysis of possible adaptive operational procedures or design modifications that could improve water system efficiency.
