Opinion: Wildfire hazards are growing exponentially. Here's what we should do to reduce the risk. [Opinion]

Ph.D., is a retired land use attorney and planning consultant who has written widely on environmental issues. He lives in Point Loma.

Wildfire has become a year-round hazard throughout California and much of the West. In the not-so-distant past, we expected an uptick in wildfire in the summer and fall, and a tapering off as the usual rainy season took over in the winter and spring. Those expectations now feel like ancient history.While we currently are not facing anything as dramatic as the conflagrations that recently swept across Canada, our own experience demonstrates we are far from immune to such risks.

The “why” is concerned mainly with climate change. Scientists cannot be certain that any particular wildfire is the product of a warming climate, but the National Academy of Sciences study shows that the burned area of wildfires over the past 50 years is 172 percent greater than would have occurred under previously normal natural conditions.

Climate change effects are maddeningly compounding. On the one hand, a warmer climate promotes drought, turning historically lush forests and meadows into tinderboxes. Once they ignite, wildfires spread more rapidly than in the past and burn at temperatures that defy typical firefighting methods. While these fires would at one time have impacted primarily rural areas, the spread of development into the wildland-urban interface now makes entire communities vulnerable.

Canadian wildfire smoke changed sky's color, not chemical releaseCanadian wildfire smoke changed sky's color, not chemical releaseSocial media users are suggesting the orange-yellow haze seen over the United States in June 2023 was due to the release of ammonium nitrate, not Canadian wildfires. This is false; atmospheric scientists confirmed the blazes were to blame, saying smoke particles refract light to change the appearance of the sky.
