Which clearly you don't. I often argue on here that climate change exists and it's caused by humans. Harvey is the 17th strongest hurricane to strike the U.S. dating back to 1851. First category 3 or strong to strike the U.S. since Wilma in 2005. That major hurricane drought is by far the longest in U.S. history. The Gulf of Mexico has been very warm for years and it's not unprecedented to see rapid intensification of a hurricane like we saw with Harvey. The amount of rain? 30" of rain from a tropical system is not uncommon, though as you go over 30" it becomes less and less common. Texas' state record for rainfall from a tropical system? 48" and that occurred in 1949 I believe. Was that climate change too?
Large blocking ridge over the West along with the timing of an upper-level low dropping out of the Great Lakes is the sole reason Harvey stalled. Tropical systems are warm core lows. They tend to be much more confined and don't influence the overall upper-level flow like some of the larger scale features. Thus, Harvey stalls.
