About climate change

Tackling climate change is a priority for us and we're working hard to protect fish, farms, and waters from the damage that rising temperatures and shifting precipitation patterns will cause in Washington. ​Excess carbon dioxide and a changing climate are causing wide-ranging impacts.

Ecology Director Maia Bellon announces a first-of-its-kind regulation to reduce carbon pollution to help slow climate change.

Climate change changes everything

With a temperate climate and typically wet weather, you might think Washington would fare better than many places in dealing with climate change. The truth, however, is that Washington faces serious impacts to snowpack and water supplies as temperatures climb.

Your weather

Climate change leads to more widespread extreme weather events like severe storms and flooding that can affect your home. Learn about extreme weather.

Water supplies

Washington communities rely on snow-fed water supplies to provide safe and clean drinking water. Climate change has already altered and will continue to alter snowpack and streamflows. This affects where, when, and how much water is available.

Your food & water

A reliable supply of water is vital for communities, businesses, industries, the environment, and quality of life in Washington. Learn how Washington's water supplies will be affected by climate change.

Marine waters, rivers, and streams

Communities in the interior of the state and on marine shorelines support the way of life in Washington. Activities like fishing and skiing make Washington a destination for outdoor enthusiasts. 

Your activities

How we live today may not be the same in years to come. We may see a loss of coldwater fish and shellfish, like salmon, oysters, and clams. Learn about warming rivers and streams and acidifying marine waters.

Climate action

Protecting the state's fish, farms, and communities from the impacts of climate change is a priority for us. However, taking meaningful steps toward addressing climate change must be a collaborative effort that also includes cities, counties, private businesses, and organizations. Through teamwork, we can meet the challenges that a changing climate presents and find solutions to counter the impacts.

Your future

Record-setting drought and wildfires are sobering examples of what the future could look like if we don’t take action on climate change. Learn about Washington's progressive approach to reduce carbon pollution to help slow climate change.
