Climate Impacts Group

A New Climate Planning Tool for Local Governments

The Climate Impacts Group has created a publicly available web application to help local jurisdictions navigate the large volume of climate information available for Washington and apply it in their climate resilience planning. Research Scientist Matt Rogers explains what the tool is and how it can be used in this blog post published by the Municipal Research and Services Center.
