I certainly hear that climate was exactly the same up until 20 or 30 years ago, when things began getting amazingly hotter in a way which has never happened before, ever. So any reports of bad weather in the 1930s were just that, weather, not climate change.

In the same way, the recent storm that hit New York and the rest of the east coast is said to be caused by climate change; the great storms that hit New York in the 1930s, and there were several, were just regular storms.
