As is normal these days, the blame game is already being waged in the wake of the most recent 2018 Californian bushfires. On the one hand are the doomsayers who claim the fires are a result of climate change. At the other end of the spectrum are those blaming “environmental terrorists” for preventing effective pre-fire management, such as forest thinning and fuel-reduction burning.
Depressingly, the climate changers include influential Australians such as Stuart Ellis, CEO of the Australasian Fire and Emergency Services Authority, and Richard Thornton, director of the Bushfire Cooperative Research Centre. Both are quoted in The Guardian newspaper attributing the Californian fires to climate change, with no qualification. Fascinatingly, the second group includes Ryan Zinke, the US Secretary of the Interior, and Sonny Perdue, US Secretary of Agriculture, who oversees the U.S. Forest Service. Zinke makes no bones about his view that responsible preparation of potential fire grounds was prevented by environmental zealots, whom he brands “terrorists”.
As in most matters where science, politics and human affairs intermix, the reality is more complex than either of these contrasting opinions. As happens so often in the media these days, the single-issue commentators are not addressing the fire problem but are using alarm over the fires to promote another agenda. For example, Australian bushfire research and emergency response agencies promote climate change anxiety to generate increased funding; the Trump administration wants to revive logging for economic and social reasons, and cites overstocked, dying forests (locked away by ‘green’ administrations) as the fundamental cause of the fires.
I am not an expert on the Californian situation, but I have been there many times and have many colleagues in the American fire community who have helped to educate me and shape my views. What follows is my perspective on what is going on, and what is likely to transpire. I am trying to look at the bigger picture, rather than focus on one issue or another.
For a start, California is a big place with a wide range of climates, vegetation and topographical situations and therefore a range of different bushfire challenges. Irrespective of any recent “climate change”, most of California has always experienced hot, dry summers and cool wet winters, and droughts have always periodically occurred. There is also (usually in late summer) the scourge of the infamous Santa Ana winds. These are hot, dry, strong winds originating in the desert country to the east that sweep down the Sierra Mountains into coastal southern California. This air mass is so dry, it acts on a bushfire like opening the door of a blast furnace. Furthermore, wind velocity often peaks between midnight and dawn, ensuring people in the path of a newly-started fire receive little warning and awake to be confronted by wind-driven flames.
