1. We've had fewer hurricanes the past 2 years, not more.
2. Climate change deniers aside, the effect of global warming on hurricanes is very much unknown at this point.
3. None of this has any impact on earthquakes.
4. There were already known to be natural 20-30 storm cycles in the US. The last such cycles ended in the 60s, before large numbers of people migrated south. Thus they took the "calm period" to be normal, and expected to stay that way forever. When the storms returned, more people were living in high risk areas than ever before, and so more are affected, more property destroyed, and people chalk it up to the storm itself being "worse."
