I wonder if people back then also ran around saying the sky is falling. It's not like the people in 1910 did anything to stop global warming. They continued industrialization worldwide and ended up on the other temperature maximum of the past 100 years. It's characteristic of any cyclic process.
Some would have you believe that we should have stopped burning fossil fuels in 1910 to avoid all the emissions over the next century. Did the gains of 100 years of machines outweigh the effect on climate? that's the question.
