I get the feeling that droughts have happened before, are happening now, and will happen again; and we are just not able as humans to control the climate.

In fact I found this study that proves that history does repeat.

Thankfully, due to technological advancement though - it is nowhere near as damaging as it once was - in fact now these are barely a blip on the radar on human life. In times past, it is easy to forget that a simple drought halted all commerce, caused great famines, and without transportation and local food sources available, people were dying.

Just take a look at the history and see the trend lines for the evidence of improvement that advancements like electricity and internal combustion have given us:
