In a recent interview that covered the gamut of oft-cited threats to agricultural sustainability and food security (drought, food safety, energy disruption, economics, terrorism, chemical pollution, genetic pollution, impacts on pollinators, soil erosion, climate change,…
Washington State, 10th in milk production nationally, is also at the top of the list for greenhouse gas (GHG) emissions produced from dairy cattle. According to the latest statistics by the EPA, in 2012 Washington State ranked 8th in methane (CH4) emissions from dairy manure management and 12th in nitrous oxide (N2O) emissions (EPA, 2014). […]
A new paper published in Environmental Science & Technology (DeLucia et al., 2014) suggests that scientists have drastically underestimated the earth’s theoretical potential to produce biomass – by as much as 2 orders of magnitude! That’s going to take a minute to wrap my mind around. The rationale of the authors is that most analyses […]
Nobel Peace Prize recipient and Director of the Purdue University Climate Change Research Center, Dr. Otto Doering, recently gave a keynote speech where he highlighted his definition of Wicked Problems facing the globe and the…
Remember last winter? As June warms and temperatures in the 90s are in the forecast, it may be hard to recall, but here in the Columbia Basin, it was dry with a few notable cold…
If you are interested in ensuring that farming is climate friendly you are likely to start thinking about nitrous oxide (N2O). Nitrous oxide is a powerful greenhouse gas (298 times as powerful as carbon dioxide,…
The US Global Change Research Program released the Third National Climate Assessment a couple of weeks ago. Unlike some other recent climate report releases (USDA’s Climate Change and Agriculture Report, the Northwest Climate Assessment and the IPCC AR5 Draft Report), this one seemed to have been picked up to a much greater extent by the […]
I’ve seen a lot of crazy ideas in the realm of agricultural technology and even toyed with a few crazy ideas myself. Crazy ideas seem to have an appeal in our society that exceeds any rational expectation for the likely success or concern regarding the downside of any given technology. Perhaps this is because people […]
Nick Bond, the Washington State Climatologist, pointed out an interesting observation at a meeting I attended last week. For summers from 2000-2010, nighttime temperatures (T-min) in many locations in the Pacific Northwest have shown a strong warming trend while daytime temperatures (T-max) have shown a general cooling trend (Panel 1). Each circle on the map […]
Over the past several months we’ve seen: a freak early-season snow storm in the Dakotas that killed tens of thousands of cattle that could take affected ranchers more than a decade to recover from, continued and expanding drought conditions in the corn belt of the Upper Midwest, extended drought cutting off irrigation water in the […]
