Oregon is getting warmer, and the effects of climate change are becoming more noticeable.
Scientists at Oregon State University have just released the latest findings in the Seventh Oregon Climate Assessment, which shows that the state’s temperatures are rising. This is although precipitation levels remain relatively steady over time.
The assessment predicts that average temperatures in Oregon could increase by up to 5°F by 2074 and 7.6°F by 2100, with the biggest increases happening in summer.
The report also highlights how the state’s precipitation patterns are changing. While winters might see more rain, summers could experience less.
There’s also a higher chance of heavier rainfall during winter, and more of this precipitation will fall as rain instead of snow. This shift is already influencing climate-related maps, including the National Plant Hardiness Zone Map.
Oregon is also seeing changes in its winter storms. Freezing rain could happen more frequently in some areas due to changes in air temperatures.
Warmer temperatures in the Willamette Basin will likely cause stronger easterly winds during the winter, which could increase ice build-up in some places.
The study also looked at how Oregon’s climate is influenced by global weather patterns, like El Niño and La Niña.
From 1951 to 2023, El Niño years were typically warmer, while La Niña years brought cooler, wetter conditions. However, the strongest El Niño events were linked to the heaviest precipitation and runoff.
Drought is another concern. The assessment shows that Oregon has experienced drought conditions in 18 of the past 25 years.
With rising temperatures, the risk of drought is expected to increase, particularly in the western Cascade Range and the southern Coast Range.
Drought could become a major issue statewide, especially during the summer months.
The economic and social impacts of climate change are also significant. Increasing wildfires and droughts have already started to affect industries like timber and agriculture.
Wildfires are reducing timberland prices, and economic losses from wildfire smoke could cost Oregon’s economy over $1 billion annually. Drought conditions are also linked to mental health issues like anxiety and depression, particularly in rural areas.
Social systems are feeling the pressure, too. Oregon’s legal system is seeing more cases related to climate change, including lawsuits over issues like mitigation and adaptation.
The state’s land-use planning system, which encourages dense housing and mass transit, may play a key role in adapting to climate change.
Agriculture, particularly Oregon’s vineyards, is also being impacted by rising temperatures and wildfires.
Heat waves are especially harmful early in the growing season, but Oregon’s vineyards have been adapting, with research helping growers deal with these changes.
The Oregon Climate Change Research Institute (OCCRI) has been studying these changes under Oregon House Bill 3543.
This report, which builds on earlier assessments, aims to guide the state’s planning for future climate impacts and help it adapt to the changes ahead.
