PLANET IN PERIL

The Energy Mix On May, 2016, the Landsat 7 satellite (NASA) acquired this false-colour image of the wildfire that burned through Fort McMurray. Advanced technology allows it to penetrate clouds and smoke to reveal the hot spots associated with active fires. Smoke appears white & burned areas appear brown. More than two thousand wildfires hit British Columbia in 2017. Another massive one consumed much of Fort McMurray, Alberta a year earlier. Mike Flannigan, A University specialist in wildland fire, says both were connected to climate change.  Story here.

It's no secret that the now-infamous bug-killer, DDT , persists stubbornly in the environment. Still, what scientists found in lake sediments they recently analyzed in the Atlantic province, 50 years after it was last used there, shocked them. The sediment in all five lakes they tested (representing numerous watersheds), were laced with DDT at levels up to 450 times beyond what would be considered safe for key aquatic species and even entire food webs. by Larry Powell A plane sprays DDT on bud worms in Oregon, 1955.  Photo by Forest Health Protection. In some ways, it was like a real war. In the early fifties, governments and the forest industry teamed up in New Brunswick to launch a massive aerial assault against spruce bud worms.  The pests had probably been eating their way through conifer stands in eastern Canada and the U.S. for thousands of years. But now, they were causing hundreds of millions of dollars of damage yearly to forests of mostly spruce an

PHYS ORG Drift ice in the Arctic ocean. Wickimedia commons. Over the last 40 years, Arctic sea ice thickness, extent and volume have declined dramatically. Now, a new study finds a link between declining sea ice coverage in parts of the Canadian Arctic and an increasing incidence of summer heat waves across the southern United States. Story here.

PHYS ORG Flooding in Saskatchewan. A PinP photo. The frequency of downpours of heavy rain—which can lead to flash floods, devastation, and outbreaks of waterborne disease—has increased across the globe in the past 50 years, research led by the University of Saskatchewan (USask) has found. Story here.

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.

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.
