Ice, Ice…Maybe?

Q&A with Anders Carlson and Aaron Hartz of the Oregon Glaciers Institute By Paris Edwards Did you know that the Northwest is the most glacier-rich region in the lower 48? Glaciers throughout the region provide essential cool, late-summer water for irrigation, fish, and for our taps. Their fate under warming climate conditions, however, is shaky. Even […]

How Can New Remote Sensing Technologies Help Evaluate the Effectiveness of Resource Conservation Measures?

By Amanda Stahl and Alexander Fremier, Washington State University Washington State is taking steps to foster environmental stewardship in agriculture using an alternative approach to direct regulatory oversight. Twenty-seven counties in Washington have opted into the Voluntary Stewardship Program (VSP), which requires them to self-assess (with state oversight) whether voluntary management actions are maintaining or […]

What Does Climate Change Mean for Flooding in the Columbia River Basin?

By Karen Hills Previous posts on AgClimate.net have focused on research related to anticipated climate change impacts on water availability and timing of available irrigation water in the Columbia River Basin, given the concern with having sufficient water to support the range of uses in the region. But is too little water the only concern? […]

Check it out: Putting Oregon’s September Fires in Past—and Future—Context

By Sonia A. Hall Most of us probably agree that 2020 was an unprecedented year in many ways. Much of the western U.S. will remember 2020 for, among other things, the extensive fires that burned across many states. One of those states is Oregon, where climatic and weather conditions converged during Labor Day to enable […]

A Review of Climate Change Research in the Columbia River Basin: Missing the Mark on Agriculture

By Paris Edwards Our understanding of regional climate change effects today will be used to inform management, policy, and the new scientific endeavors of tomorrow. With this in mind, a team of doctoral students from the Water Resources Department at the University of Idaho in Moscow carried out a systematic review of all peer-reviewed studies […]

Pathways to Progress in Tackling Stormwater Runoff in Near-Urban Agricultural Areas

By Kevin Hyde, Puget Sound Partnership Stormwater runoff, particularly from roadways, is one of the leading sources of water pollution in Puget Sound. Stormwater pollution impacts people and ecosystems in different ways. Many of the things Puget Sound residents hold dear, like swimming along rivers and beaches, harvesting and eating shellfish, and fishing for salmon, […]

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 […]
