Unprecedented smoke from British Columbia's wildfires in 2017 is helping scientists model the potential impacts of nuclear war on the Earth's climate, says a study from Rutgers University.
Inhaling smoke from a wildfire can be equal to smoking a couple of packs of cigarettes a day depending on its thickness, says a researcher studying wildfires in Western Canada.
When wildfire smoke blankets a province, as it did in B.C. for weeks this summer, there are marked increases in asthma attacks and respiratory infections, as well as smaller increases for things like heart attacks and cardiac arrests, a B.C. scientist says.
Environment Canada says smoke from British Columbia's wildfires will likely result in high-risk air quality levels in parts of central Alberta by Wednesday, July 19, 2017.
