Arson has nothing to do with climate change and the reason they have run out of water is because the mayor ordered it to be so. Also , all the environmentalists wanted the clearing of the trees and bushes, which is done every year to avoid fires, to be quashed as well as it wasn't 'eco friendly'. A perfect storm set up for carnage.
They had enough water to cover what they had previously known and could reasonably have been predicted, as local fire chiefs said and I reported above
I dont believe there is one single reason, but it includes climate change, its not an either/or for all coming together in this huge combination of events.
Also, don't forget that one major reservoir in the areas had closed for repairs and remember a lot of the water supplies are privately owned/managed and are no under direct state control, just as we have problems with for example Thames water. I counted 7 different water agencies on google all who have a part in it.
