The place where those fires are is the same latitude as here. All of the vegetation is still dormant and dry. It is windy most of the time. Perfect environment for big grass fires.
It is ludicrous to say it is caused by global warming. The grass is dormant there every year and the wind blows every year in February. All it takes is a spark or flame. It didn't spontaneously combust because the average temperature might be a few degrees warmer which has always happened going back as long as people remember.
