I think its time to pray for the situation in California, that it must get rain again and that people will share the water in a good way without getting angry at each other.
And we should also remmeber all the other places on the earth where people lack water.
i live in a country with more water than we can possibly use, and with the climate changes we will probably get problems with local floods and avalanches rather than drought. But when i read the news i know this is a thing God can help us with. Both directly and by helping people making right decisions.
At least we can pray and hope for it
