[Elecraft] (OT) Ca Fires

[Wayne Burdick]

There are at least three factors making fires both more intense and more frequent in recent years: 

1. Our power companies (including PG&E) have not been diligent about clearing trees away from residential and HV lines. In my own neighborhood I've spotted many houses with power feeds that are intertwined with tree branches. When I do, I alert the home owners to the existence of a hotline for PG&E trimming service. 

2. Due to either negligence or budget problems, they're not replacing old equipment fast enough. Like gas infrastructure, there are transmission towers and poles 50 to 100 years old in active service.

3. Trees in California (and in the west, generally) have seen rapid increases in die-offs due to extended drought, as well as bark beetles, sudden oak death (SOD) and other infections. I travel around California often, and everywhere I go I see patches of brown, dead trees in what used to be pristine forest. 

Historically, bark beetle larvae were suppressed by winter freezes. But average temperatures have been steadily rising. (First-hand experience: When we moved to Belmont 25 years ago, we used to have a couple of days every winter with lows below 30 degrees. Over the past three years the lowest I've seen was 39.) As far as trees are concerned, it only takes a couple of degrees to shift the balance. The larvae now survive most winters and reproduce furiously, eating everything in sight. They're also able to migrate to higher elevations, getting into more stands of trees.

Information on this phenomenon abounds, but one particularly good summary, from Yale, can be found here:

Of course we're used to disasters both man-made and natural in CA, and still we persist  :)
