Hurricane Florence is not climate change or global warning. It’s just the weather–Roy Spencer | NOT A LOT OF PEOPLE KNOW THAT

"...Writing for NBC News, Kristina Dahl contended, “With each new storm, we are forced to question whether this is our new, climate change-fueled reality, and to ask ourselves what we can do to minimize the toll from supercharged storms.”
...But like most claims regarding global warming, the real effect is small, probably temporary, and most likely due to natural weather patterns. 
Any changes in hurricanes over 70 years, even if real, can easily be part of natural cycles — or incomplete data...
...Until 2017, the United States went 11 years without a major hurricane strike — something that is statistically very improbable. 
Nine years into that 11-year hurricane drought, a NASA scientist computed it as a 1-in-177-year event.
My point is that nature varies, and unusual things happen sometimes.
Now it’s fashionable to blame stalling hurricanes on global warming...
...Well, aren’t we being told these storms are getting stronger on average? 
The answer is no. 
The 30 most costly hurricanes in U.S. history (according to federal data from January) show no increase in intensity over time. 
The monetary cost of damages has increased dramatically in recent decades, but that is due to increasing population, wealth and the amount of vulnerable infrastructure. 
It’s not due to stronger storms.
If humans have any influence on hurricanes at all, it probably won’t be evident for many decades to come. Natural variability is simply too large. 
This should not be surprising given that humanity’s greenhouse gas emissions have caused only a 1 percent change in the natural energy flows coursing through the climate system."
