Is it just me or does the weather seem to be abnormally tempermental these past few weeks?

I know some of this was caused by arsonists (which is terrible, who could do such a thing?!), but some of it was simply caused by bushfires, which I hear do happen.

The thing is I can't understand why people would do such a thing to their fellow human beings. Like the president of Australia said this is mass murder and the people who started these fires should be treated as serial killers.
