Climate change is already affecting global food production—unequally

Image
PHYS ORG A soy field in Canada. A PinP photo. The world's top 10 crops— barley, cassava, maize, oil palm, rapeseed, rice, sorghum, soybean, sugarcane and wheat—supply a combined 83 percent of all calories produced on cropland. Yields have long been projected to decrease in future climate conditions. Now, new research shows climate change has already affected production of these key energy sources—and some regions and countries are faring far worse than others. Story here.

A warming Arctic produces weather extremes further south!

PHYS ORG The Northern Hemisphere Jet Stream can be seen crossing Cape Breton Island in Eastern Canada. A NASA photo. Atmospheric researchers have developed a climate model that can accurately depict the frequently observed winding course of the jet stream, a major air current over the Northern Hemisphere. It demonstrates that the jet stream's wavelike course and subsequent extreme weather conditions like cold air outbreaks in Central Europe and North America are the direct results of climate change.  Story here.

Even Canada's beloved grey jay is not immune from the ravages of manmade climate change.

Decades of Canadian research, just released , finds "strong evidence" that increasing "freeze-thaw" cycles are destroying food the birds store away in the fall. This, in turn is damaging their ability to reproduce and likely playing a role in a severe population decline in at least one region. by Larry Powell   The grey jay,  AKA as Canada jay or "Whiskey-Jack." Photo by Steve Phillips, via  Canadian Geographic  magazine. It's been known for some time that our changing climate is leading to reductions, even entire removal of many species from certain areas (a process called "extirpation"). This new research by the University of Guelph, sheds more light on just how that happens.  Using 40 years of breeding data, scientists studied grey jays  (scientific name p erisoreus canadensis )   at the southern edge of their range in Algonquin Park, Ontario. (The birds can be found in all Canadian provinces and territorie

Beat the Heat: Canada's French-fry potatoes in climate change trouble

Canadian Science Publishing After PEI, Manitoba is Canada's largest potato-producing province.  Over 1200 million pounds are processed here each year on about 80 thousand acres.  A PinP photo. Desiccating summer heat, brought on by climate change, could have adverse effects on Canada's potato industry. In a recent study, researchers examined the heat stress response of 55 potato varieties to estimate how they might fare under changing climate conditions. The news is not good.    Details here.
