how climate change Could affect the interrelationships between

the environment and the people of the Northwest.

The vast array of climate impacts that occurred over this record-breaking warm and dry year, coupled with the impacts of a multiyear drought, provide an enlightening glimpse into what may be more commonplace under a warmer future climate. Record-low snowpack led to water scarcity and large wildfires that negatively affected farmers, hydropower, drinking water, air quality, salmon, and recreation. Warmer than normal ocean temperatures led to shifts in the marine ecosystem, challenges for salmon, and a large harmful algal bloom that adversely affected the region’s fisheries and shellfish harvests.

observed

climate

Warming is projected to continue in all seasons, dependent on global activity. Oregon is projected to warm by about 4-9°F by 2100, depending in part on whether global emissions follow a lower (RCP 4.5) or higher (RCP 8.5) path.

Future

climate

Oregon continues to warm in all seasons, in part due to human activity. The entire Pacific Northwest has warmed about 2°F since 1900.

 

The last three years (2016-2018) were all warmer than the 1970-1999 average, and 2015 still stands as Oregon’s warmest year on record.

CURRENT

TRENDS

Oregon’s warming trend continues. As shown in the observations in Figure 1a, after the record-warm 2015 (the recent peak of the observed temperature graph), calendar years 2016 and 2017 were also warmer than the

1970-1999 average though not as warm as 2015.

Anchor 1

Strong climate variability is likely to persist for the Northwest, owing in part to the year-to-year and decade-to-decade climate variability associated with the Pacific Ocean.
