Climate is always changing so the answer is yes, but, keep in mind, there is no such thing as anthropological climate change. Also, there have been more intense storms than Harvey to hit TX, the 1900 storm that wiped out Galveston is one such storm.
You really are a mental midget... you're comparing a Hurricane in the 1900's when they didn't have the warnings or knowledge they do to say and that was a direct hit to Galveston... which is basically just a sand bar..
To this storm which because of the increased warmth in the atmosphere is bringing to sure what is being described as the one in 500 year storm..
Warmer air, warmer seas will bring in more moisture in the air... and if you can see that over 980 million cars on earth, factories and cutting of mass forests is not in creasing green house gasses in our atmosphere.... then you're not just stupid you're a fool.
