    “Emissions pricing” of foods such as beef would come with significant costs and a less-than-notable reduction in greenhouse gas emissions, according to a pair of University of Guelph professors. Responding to an often-cited British/U.S. study that recommends “emissions pricing of food commodities” as a way to fight climate change, Guelph food economics professor Michael von […]

  • Fires, floods and rain dominate weather in 2017

    January 11, 2018

    Too much, is how Environment Canada’s weather service describes 2017. “Between the few floods, the many wildfires and record dry temperatures, 2017 was a year of too much — too dry, too hot, too fiery, too wet, too cool, but not too cold.” That observation sets the tone for Environment Canada’s top 10 weather stories […]


  • Predicting the effect of climate change on crop yields

    January 4, 2018

    University of Illinois College of Agricultural, Consumer and Environmental Sciences – Scientists now have a new tool to predict the future effects of climate change on crop yields. Researchers from University of Illinois are attempting to bridge two types of computational crop models to become more reliable predictors of crop production in the U.S. Corn […]

  • Since when did plants start using light?

    December 28, 2017

    A study of rocks from Canada’s Arctic has given scientists from Montreal’s McGill University a new clue as to how long Earth’s plant life has been using sunlight to feed. A type of algae called Bangiomorpha pubescens — fossils of which were first found in rocks in Arctic Canada in 1990 — is believed to […]


  • Canadian beef production using less water

    December 21, 2017

    Beef Cattle Research Council – Canada’s beef industry has dramatically reduced its water footprint over the past several decades, and that trend is expected to continue, a new study has found. The amount of water required to produce one kilogram of Canadian beef has decreased by 17 per cent from 1981 to 2011, due largely […]

  • Russian winter grains hit by weather

  • Warming overnight lows across the Prairies

    December 7, 2017

    Thermometer on snow shows low temperatures under zero. Low temperatures in degrees Celsius and fahrenheit. Cold winter weather twenty under zero.Thermometer on snow shows low temperatures under zero. Low temperatures in degrees Celsius and fahrenheit. Cold winter weather twenty under zero.

    Several months ago I received a question about winter temperatures and humidity levels along with another question about overnight low temperatures. In particular, about whether or not there has been a trend towards warmer overnight lows. While these two questions are not totally connected I began looking into the numbers and here is what I […]

  • Temperature threshold seen for plants’ ability to fight disease

    November 30, 2017

    Michigan State University – An issue of global concern is the anticipated shortage of agricultural output to meet the steady rise in human population. Michigan State University scientists understand that overcoming crop loss due to disease and adverse weather will be key in achieving this goal. One of the best historical examples of this is […]


  • Chance of La Niña this winter at 65 to 75 per cent

    November 23, 2017

    The sun sets over frozen prairie fields near Rosser, Manitoba as temperatures dip below -30 degrees Celsius in mid-December.

    Reuters – A U.S. government weather forecaster has added its voice to a growing chorus calling for La Niña conditions to continue through the winter. The Climate Prediction Center (CPC), an agency of the National Weather Service, in a monthly forecast pegged the chance of La Niña developing at about 65 per cent to 75 […]

  • Has breeding highly productive corn reduced its ability to adapt?

    November 16, 2017

    University of Wisconsin-Madison – Stuck where they are, plants have to adapt to their environments, responding to stresses like drought or pests by changing how they grow. On a broader scale, crop breeders need to be able to develop new varieties that are adapted to a new location or changing growing conditions in the same […]
