"The question isn't that hurricanes preexisted humans but that their increased intensity is likely due to the greater energy found in todays' oceans. The water is warmer and feeds that energy to developing hurricanes. Without the effects of climate change hurricanes would likely be weaker and would certainly cause less flooding(warmer air can carry more moisture)."
I often agree with you, but not this time. I believe in global warming, but Texas has a long history of being destroyed by hurricanes:
