Extreme weather events are more common than ever. For example, in 2021 the north Willamette Valley had catastrophic ice storms in late winter. The winter melted into a warm spring and exceptionally hot summer that was exemplified by the 113 F “heat dome” in late June. While the average annual temperatures in our region will only increase by a few degrees each decade, these extreme (greater than 10 F above average) hot and low-temperature events have devastating and long-lasting effects on nursery producers. Learn about how climate change and extreme weather are affecting nursery production, and what growers can do about it.
