The word out of the US is that the problems were exacerbated by the policy of redirecting water into the Pacific Ocean, that was formally sent down to California, thus making many areas of California bone dry and susceptible to forest fires.
The state government also had a policy of not removing old debris from forests and preventing trees from being cut down in and around residential areas, as used to happen, to prevent forest fires getting out of hand.
Added to that, under funding of the fire service in California had led to fire hydrants running dry.
You couldn't make this up.
A similar policy of preventing 'hazard reduction burning' was also in place in Victoria, Australia up until the bushfires of 2009, that killed over 170 people.
It appears that our leaders are playing games with our lives and then blaming climate change for the catastrophic fires that sweep through populated areas.
Even the BBC are questioning the policy of not carrying out proper forest management.
