Heat and drought and fire. A common litany these days for California — a state that has, year after year, been wracked by a series of unprecedented climate extremes.
After a brief respite this winter, northern parts of a state reeling from woes related to human-caused climate change again settled into drought this summer. Having received near record amounts of rain during winter — enough to wreck the spillway at the Lake Oroville Dam — vegetation sprang anew. This rain-spurred growth then subsequently dried — developing widespread fuels for fires.
(Northern California near Santa Rosa saw humidity drop to as low as 10-12 percent even as strong winds raged through the region. Such dry, windy condition are key ingredients for increasing fire hazard. Widely available fuels from the abnormally wet winter carried over into a drier than normal summer to increase fire risks.
