Fact of the week

  • European wheat lacks climate resilience

    January 8, 2019

    Aarhus University – The climate is not only warming, it is also becoming more variable and extreme. Such unpredictable weather can weaken global food security if major crops such as wheat are not sufficiently resilient – and if we are not properly prepared. A group of European researchers, including Professor Jørgen E. Olesen from the […]

  • How plants branch out to access water

    December 31, 2018

    Cutaway of Plant and Roots in Dirt

    University of Nottingham – New research has discovered how plant roots sense the availability of moisture in soil and then adapt their shape to optimise acquisition of water. The discovery could enable crops to be bred which are more adaptive to changes in climate conditions, such as water scarcity, and help ensure food security in […]

  • Rural children’s asthma risk not a simple story

    December 23, 2018

    We’ve seen studies that suggested rural children are less likely to have asthma, presumably due to early-life exposure to dust and other environmental allergens which may have protected them. However, a new University of Saskatchewan study shows “this may not be entirely the case,” researcher Oluwafemi Oluwole said in a recent release. “We found that […]

  • Researchers to unearth old Red River flood evidence

    December 18, 2018

    NDSU Extension – Researchers at North Dakota State University and the University of Minnesota are using a grant from the National Science Foundation to search for evidence of floods along the Red River of the North through trees. Joe Zeleznik, NDSU Extension forester, and Scott St. George, assistant professor of geography at the University of […]

  • U.S. government report says climate change will batter economy

    December 11, 2018

    Reuters – Climate change will cost the U.S. economy hundreds of billions of dollars by the end of the century, hitting everything from health to infrastructure, according to a recent government report that the White House called inaccurate.

  • Alberta clippers and Colorado lows

    December 4, 2018

    So far this winter Western Canada has not seen any big winter storms develop. When we do see big winter snowfalls, most of them come from areas of low pressure that develop to the lee of the Rocky Mountains. One area of development is over Alberta, producing what is affectionately known as an “Alberta clipper,” […]

  • Extreme heat increasing in both summer and winter

    November 27, 2018

    American Geophysical Union – A new study shows extreme heat events both in the summer and in the winter are increasing across the U.S. and Canada, while extreme cold events in summer and winter are declining. A new study in the in Journal of Geophysical Research: Atmospheres, a publication of the American Geophysical Union, examined absolute […]

  • The science behind snow fences

    November 20, 2018

    Driving home the other day I began to notice just how many people install snow fences, either to stop snow from accumulating in an area, usually their driveway or parking area, or to trap snow in an area, mostly over septic fields. Once I really looked at where people were installing these fences I realized […]

  • Ragweed may head further north with climate change

    November 13, 2018

    University of Massachusetts Amherst – A new predictive model developed by an ecologist at the University of Massachusetts Amherst and a climate scientist at the University of Washington suggests that climate change may allow common ragweed to extend its growing range northward and into major northeast metro areas, worsening conditions for millions of people with […]
