Want to understand what carbon fertilization is, and what it could mean for the American West? Take a look at Linnia Hawkins’s (Oregon Climate Change Research Institute) post discussing research on whether the American West could become both drier and greener under climate change, which would affect wildfires. Linnia’s full article is in the Climate CIRCulator.

Check out Meghan Dalton’s (Oregon Climate Change Research Institute) discussion of a published article about whether the 2015 “snow drought” is a harbinger of future climate changes.  Read Meghan’s article in the Climate CIRCulator.

Over 30% of wheat is grown in temperate drylands globally, which are expected to see a 41% increase in suitability for rainfed agriculture. Photo credit: Flickr user Sparky, under CC BY-NC 2.0.

One challenge I struggle with when sharing research focused at global scales is how to tease out answers to questions that are meaningful in the region and at the scale I work in. My approach is to focus on how the big picture results sketch out, and think about what it all means (even when the specifics are not exactly right, which they rarely are). Hopefully I’ll be successful in this article about a paper I co-authored, on agriculture in temperate drylands (I define these below) at a global scale. Led by Dr. John Bradford at the U.S. Geological Survey, we looked at temperate drylands across the world, and explored how rainfed (non-irrigated) agricultural areas could shift as the climate changes. Read on, and see if I convince you that wheat growers in the Pacific Northwest should care about these results.   Continue reading →

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.
