Whether started naturally or by people, fires worldwide and the resulting smoke emissions and burned areas have been observed by NASA satellites from space for two decades . The smoke slightly cooled Earth’s surface by an as-yet undetermined amount (likely a small fraction of a degree, similar to the cooling effect of a moderate volcanic eruption). As such, federal and state agencies have developed certain arrangements to collaborate on management activities across California’s forests. Forest fire smoke - a danger to our health. Many people believe that all wildlife flees before the flames of a fire like the animated characters in the movie “Bambi.” Contrary to this belief, scientists studying animal behavior during the 1988 burns in the Greater Yellowstone area saw no large animals fleeing the flames. “We do know that exposure to particulate matter, which of course is of great concern for human health, can affect birds as well,” says Olivia Sanderfoot, a National Science Foundation Graduate Research Fellow at the University of Washington Seattle who studies how air pollution affects birds. Smoke is an aerosol (or mist) of solid particles and liquid droplets that are close to the ideal range of sizes for Mie scattering of visible light. Forest fires are often a concern in Canada, especially during dry, hot summers. But for most people, it’s a nuisance irritation without any long-term bad effects. There are bigger particles, but we worry less about those.
