Weather in the Northwest has gotten more variable. We have recently experienced drought for two years followed by flooding in 2017. The 2015 drought coincides with future climate projections for the Northwest: warmer temperatures leading to lower and earlier melting of snowpacks. Though trees are locally adapted to climate and can tolerate moderate changes, rapid and large changes in climate may be beyond the capacity of some species. As we saw in 2015, longer and drier growing seasons affect tree regeneration, growth, and mortality. This poses challenges for foresters, which Chris Schnepf discussed in a recent article.

“This is the first good news I’ve heard about climate change” was among the feedback received after delivering a talk about changes expected for Pacific Northwest’s agriculture. The audience was primarily ranchers attending the Northwest Grazing Conference in Pendleton, Oregon this past May. Scheduling conflicts prevented the talk’s author, Chad Kruger, director of the Center for Sustaining Agriculture and Natural Resources from attending, and with some trepidation I agreed to present the topic on his behalf.
For many Americans, climate change is at best an abstract challenge, seemingly serious but without immediately obvious specific threats to one’s life and business. To the skeptic, it is a political football and a dark conspiracy, some nefarious excuse dreamed up to gain economic and political advantage for one interest group over another. With this in mind I attempted to summarize and translate the results of Northwest-focused climate research to an audience I expected viewed the topic at large with some level of hostility.

“Family forest owners own a large portion of forests in many PNW regions” (Photo – C. Schnepf)
Many westerners presume any forest they drive by is managed by the U.S. Forest Service. But nationally the largest portion of forests are owned privately. Even in the West, key regions have a very high percentage of private forests. For example, over half of the forests in the Idaho Panhandle are private.
Some people debate whether forestry should be considered part of agriculture. Like farmers, forest owners and managers are discerning how to adapt their management to a changing climate. But forestry in North America starts from a different point than most cropping systems. Continue reading

One of the best things about my work is that it connects me with researchers from a wide range of disciplinary backgrounds who are committed to conducting science that informs natural resource management decisions. I’ve been fortunate to work with WSU researchers studying regional climate change impacts for nearly 6 years now, and over that time many of my academic colleagues have developed new skills related to communicating their research to diverse audiences. I’ve also witnessed scientists’ growing interest in learning from stakeholders who make decisions about managing agricultural and natural resources “out there in the real world”. Continue reading

In a previous article I explored how climate change in California’s wine country—coupled with shifting temperature and precipitation patterns in Oregon and Washington—may catalyze new opportunities for winegrape production in the Northwest. I also suggested that these opportunities might be accompanied by an increase in locally produced cheeses due to growth in the region’s dairy industry. In this article, I’ll discuss research indicating that during the 21st century, climate change impacts could lead to more favorable conditions for milk production in the Northwest relative to other current dairy centers of the U.S. In 2016, Idaho, Washington and Oregon produced roughly 11% of the nation’s milk. It is conceivable that this percentage could increase substantially in coming decades. Continue reading

As a climate change scientist at the Conservation Biology Institute (CBI), I spend a lot of my time thinking about how to deliver climate projections and climate impacts data in a useful manner. This is a challenging part of my job, because I do not make decisions on managing natural resources, so I am not necessarily the best person to determine how climate research might inform such decisions. For practitioners whose day-to-day work is managing natural resources—forests, fisheries, endangered species and their habitats, for example—thinking about future climate and potential climate impacts is challenging in a different way. Practitioners have limited time and funding to digest and incorporate this material into their plans, strategies, and actions. I expect agricultural professionals face a similar challenge, so there’s an opportunity to share ideas on how to develop effective climate-related decision-support tools.

Winter is in its final stages and spring is knocking on our door. As a Florida native living in Washington, I for one am ready for some sunshine, flowers and warmth! While I dream of that glorious spring, I’d like to reflect on what an impressive year of growth the Agriculture Climate Network experienced in 2016, and what we are shooting for over the next year.

The snow-covered landscape, the Columbia River, and the pine forests covered with signs of the recent ice storm provided the backdrop for the Climate Impacts to Water Conference, hosted by Washington State University Extension. University of Idaho climate scientist John Abatzoglou gave a plenary talk, titled Parched and Drenched: Future Climate and Water Resources in the Pacific Northwest (check out the recording here).
What I really liked about Abatzoglou’s presentation was that he focused on one key number, and then got into the weeds of what it means and why it’s important to us. That key number in this case was the fact that the Northwest has seen an increase in average temperatures of 1°C (that’s almost 2°F, if you prefer Fahrenheit), which has mostly occurred in the last 50 years. Is this an important change, and should we care? Yes, because this past temperature increase has already led to more rain and less snow, a reduced winter snowpack, and spring runoff coming earlier in the year, leaving us drier in the summer.

It’s that time again. It’s time to talk about atmospheric rivers, that key weather pattern wherein moist air from the subtropics is drawn in a line to the West Coast, delivering a significant portion of the Pacific Northwest’s winter precipitation.
Lots of winter precipitation is good for the Pacific Northwest, so long as it’s a certain type of precipitation: snow. According to a new study by CIRC and OCCRI’s very own David Rupp and Sihan Li, atmospheric rivers might not only create large precipitation events but also keep temperatures cool enough to turn that precipitation into snow.
