The earth's climate is changing more rapidly now than at any point in the history of modern civilization. While levels of atmospheric carbon dioxide (CO2) have varied over thousands of years, they are now well above any of the previous cyclical levels. Human activities, especially those related to the burning of fossil fuels, are the primary driver of this increase.

The evidence of global climate change is widespread: rising average global temperatures, warming oceans, shrinking ice sheets and retreating glaciers, decreased snow cover, sea level rise, ocean acidification and increasing extreme weather events, including wildfires.

The impacts of climate change are already being felt across the United States and the world. It is expected that extreme weather impacts will subsequently affect a range of interconnected issues and systems, from public health to food supply to local economies. However, communities across the country now have the opportunity to make changes to their systems, policies, and plans in order to reduce the worst impacts of climate change and support healthy and resilient growth.

The State of Oregon is taking ambitious action to address climate change. In 2020, Governor Brown signed Executive Order 20-04, directing State of Oregon agencies to take action to reduce and regulate greenhouse gas emissions toward meeting reduction goals of at least 45% below 1990 emissions levels by 2035 and at least 80% below 1990 levels by 2050.
