ORDINARILY, climate change adaptation tends to be a top-down process. Climate researchers identify the best climate science and data, run climate simulations, and, eventually, make that data available to end users, who put it to work in their adaptation efforts. The problem is this approach doesn’t always deliver the kind of science end users need. But that’s changing. Continue reading

Being prepared: what we got can help us understand what to expect

As I shared in my last post, “Climate is what you expect, and weather is what you get.” But if the climate is changing, and part of what experts predict is that we’ll see more extreme weather and weather-related events—think floods, droughts, big storms—what should we expect?

More than one research group is working hard to develop models that can help answer this and other questions. They are also working to collect real-world data against which to compare the model projections, to improve our confidence in what these models tell us. It is this combination of data and good models—models that do a good job at representing what actually happens in the real world—that would allow us to say to what extent a particular event is due to a changing climate, and how much is just the natural, year-to-year variability that we are all used to experiencing.

A concerned citizen wrote a letter to the editor of my local paper recently, complaining about how weather, climate, and climate change had been used almost interchangeably. Reading that letter got me thinking about the active scientific discussion on whether extreme weather or weather-driven events like floods and wildfires—the latter very much on our radar in eastern Washington this year—are due to climate change. And more importantly, it got me thinking about how to best take advantage of what we know, even when there are some complex issues we still don’t fully understand. Here I tackle the difference between weather and climate, and in a future post I will discuss what we know—and don’t—about climate change impacts and how what we do know can be useful.

Early preparation for water transfers could reduce drought impacts for agriculture and fish

As this hot, dry summer winds down across Washington State, many areas are continuing to struggle with the impacts of drought. (Those who would like a recap of August weather and drought conditions can see the WSU Drought Report here.)

Unfortunately, while the weather has become more fall-like, with welcome rain in some areas, all climate indicators point towards increased chance of warmer and somewhat drier than normal conditions through mid-2016 – as shown in the three month forecast from the Climate Prediction Center (see the maps below).

Farmers: Tell Your Story!

By David Schmidt

Reprinted from: Animal Ag

Thumbnail for 91170The party is over. Sometime in the last 50 or so years the production of food has become a mystery to consumers and farming has become a dirty word – linked to polluting of the environment and mistreatment of animals rather than a noble profession of growing food to meet the dietary needs of an ever expanding population.

What are we doing about it?

Climate Impacts Modeling 101: Interpreting What Models Say About the Future of Our Region Under Climate Change

By Liz Allen

Reprinted from: WSU CSANR Perspectives on Sustainability

Thumbnail for 91152As a PhD student with CSANR interested in improving communication about climate and agriculture between the academic and decision-making spheres, I’ve had a lot of conversations about climate models with agricultural producers, industry representatives, policy makers and regulatory officials (as well as with modelers themselves!). In the course of those conversations it has become clear that accessible explanations of how climate models are developed and how the results from climate change projections ought to be interpreted are lacking.

A team of us affiliated with WSU’s Center for Sustaining Agriculture and Natural Resources and the BioEarth research project set out to create a guide to climate modeling intended for agricultural and natural resource decision makers in the Pacific Northwest and beyond. Using examples from the 2011 Columbia River Basin Long-Term Water Supply and Demand Forecast, we describe:

  • What process-based models are
  • How global climate change projections are downscaled and applied in regional climate impacts analyses
  • The importance of understanding scale
  • How uncertainty is handled and communicated in model outputs
  • Applications of results from process-based models

This concise overview guide is the product of collaboration between modelers who specialize in agricultural, hydrological and economic systems and science communicators. We hope this will be a valuable reference resource to a wide range of people interested in understanding and using climate models. So go grab yourself a cup of coffee, give it a read and let us know what you think and what questions you have.

 

Flashback

Flashback. While cleaning out a corner of the building I work in I found several dozen old Popular Science magazines. The November 1997 issue caught my attention because of two articles featured on the front cover. See if you find anything striking as you read the titles and the first paragraphs of these cover stories. Continue reading

Videos Farmers Can Use: Stripper headers in extra-dry dryland agriculture

Reprinted from: REACCH

After years of field tests, in dry years and good years, Lauren Port shares her findings on stripper headers and benefits to soil moisture content. She claims that the work at the Ralston Project, near Lind and Ritzville, Washington, is “pushing no-till to its limits” by growing tall cereal crops.

To learn more, watch the video on the REACCH Research Seminar Series in Climate Change and Agriculture youtube channel or below.

Lauren is a masters student in the Washington State University Department of Crop and Soil Sciences working with Dr. Frank Young and Dr. Bill Pan.

 

Observations of Aphid Dynamics Provide Clues to Risks and Benefits under Climate Change

Growers can anticipate future aphid-related risks by understanding current baselines and trends – Sanford Eigenbrode

Possibly one of the most concerning factors associated with climate change is the uncertainty of its impacts on agricultural pests. Climate change can directly influence ranges and severity of pests and indirectly complicate the relationships among climate impacts, pest’s predators, and natural enemies. The complexity of biological and environmental interactions make projections difficult. Several University of Idaho REACCH entomologists, led by Sanford Eigenbrode, are addressing these important concerns by examining aphid dynamics in wheat-based cropping systems. Continue reading

Time to Talk Heat Stress!

By David Schmidt

Reprinted from: Animal Ag

Thumbnail for 90896On June 9 the temperature climbed to 97 degrees F in Western MN. Not an unreasonable temperature for the region but maybe a little early in the season. This got me thinking about heat stress. I know some regions of the US are well into heat stress season but we are just getting there.

The good news is that reminders about heat stress, and what do do about it, are coming from everywhere. The most recent heat stress article that came across my desk was from Morning Ag Clips entitled “Don’t let your reproduction suffer this year.” The article summarized a study on reproductive losses in dairy that suggested pregnancy losses could occur with max THI (Temperature-Humidity Index) values as low as 55. The general recommended threshold value is an average (17-hour) THI of 68. Continue reading
