Check it out: How does the Columbia Basin Fare as the Timing and Volume of Snowmelt Changes?

By Sonia A. Hall It is not always easy to extract regionally-relevant conclusions from global studies, such as the one discussed in the August 2020 CIRCulator article “Irrigated Agriculture, Snowmelt, and Climate Change.” So though many of the irrigation-dependent crops studied are not typical to the Pacific Northwest, this article discusses research that synthesizes key […]

Check it out: Is Climate Change or Forest Management Causing Megafires?

By Sonia A. Hall In response to the recent—and in California, ongoing—megafires, many have been asking whether the cause is climate change or forest management. Erin Hanan wrote a blog article arguing that this is not the right question, because in many cases both contribute to what is happening. The drivers of fire activity are […]

Hot, Dry Summers Take a Toll on Trees in Western Washington

By Patrick Shults, Washington State University Extension The coastal Pacific Northwest is home to some of the best tree-growing conditions in the world.  Fertile soils, plenty of rain, mild temperatures, and short dry seasons allow trees to pack on solid growth each year.  These conditions also give them a significant advantage in protecting themselves from […]

Acting to Prepare for Severe Droughts in the Yakima River Basin

By Mengqi Zhao, recent PhD graduate, Washington State University For more than fifty years, individuals and organizations in the Yakima River Basin (YRB) have been working toward improving water availability, especially for agriculture. The mismatch between rainfall (and snowmelt) timing and the irrigation season has focused these efforts on strategies for increasing water storage. However, […]

Check it out: New Studies in the Region Discuss Wildfires in the Future and How Fuel Treatments May Affect Them

By Sonia A. Hall Pacific Northwesterners, especially those of us living and breathing in the inland Northwest, expect wildfires every summer. It’s not about if, but about when, where, and how severe they will be, both in forest and rangeland landscapes. As with many other aspects of natural resource management, climate change continues to add […]

An Integrated View of Water Vulnerability Across the Northwest

By Paris Edwards, USDA Northwest Climate Hub Water systems across the Northwest sustain crops, livestock, ecosystems, people and power production. These highly managed, interconnected networks of rivers, reservoirs, canals, and pipelines are economic mainstays for the region, and play a foundational role in food and energy security and sustaining natural resource livelihoods. However, climate change […]
