hazy sky in Portland, Oregon

Climate change is happening in Multnomah County, threatening our access to clean air, clean water and healthy food. The health impacts of hotter, drier summers and warmer, wetter winters create major public health challenges, especially for our most vulnerable community members. 

In the Portland region, communities of color and low-income communities already experience poorer health and disparities.

In 2021, our leaders declared racism a public health crisis, acknowledging the role systemic racism plays in creating unfair health disparities. This includes those related to climate hazards.

Climate change will make health disparities worse. Our response to climate change is an opportunity to correct this.
