One of the most visible impacts of climate change on PNW shorelines is rising sea levels. As the oceans warm, they expand, and glaciers and ice sheets melt, adding water to the seas. This is causing sea levels to rise, which is leading to coastal erosion, flooding, and saltwater intrusion into freshwater sources.
Tribal nations in the PNW are particularly vulnerable to these impacts because many of their communities are located on low-lying coastal areas. For example, the Quinault Indian Nation in Washington state has seen its coastline recede by more than 1,000 feet in the past century. This has resulted in the loss of homes, businesses, and cultural sites, as well as increased flooding and erosion.
In response to these challenges, tribal nations in the PNW are developing a variety of adaptation strategies. These strategies include:
* Retreating from the shoreline: Some tribes are choosing to relocate their communities away from the shoreline, to higher ground that is less vulnerable to sea level rise.
* Building sea walls and other coastal defenses: Other tribes are building sea walls and other coastal defenses to protect their communities from flooding and erosion.
* Restoring coastal ecosystems: Still other tribes are focusing on restoring coastal ecosystems, which can help to mitigate the impacts of climate change. For example, the Lummi Nation in Washington state is restoring eelgrass beds, which help to protect the shoreline from erosion.
Tribal nations are also playing a leading role in advocating for policies that address climate change. They are calling for action on a global scale to reduce greenhouse gas emissions, and they are also working to develop regional and local policies that support climate adaptation.
By taking these steps, tribal nations in the PNW are showing the way in adapting to climate change. Their efforts are helping to protect their communities and cultures from the impacts of climate change, and they are also providing a model for other communities around the world.
