Despite the alarmist squeals of the climate change crowd that the frequency of “extreme weather events” (one of those very vague terms that the very unscientific boosters of man-made climate change like to use to hide the fact that they are telling porkies), the US is undergoing a very large hurricane drought that has lasted for 4001 days- almost 11 years.
The Greens will be all over Hurricane Michael when or if it lands in Florida and say it is evidence of man-made climate change and we must act now, as if this is the first ever category 3 storm to hit America.
The fact is that the southern parts of the USA like the northern parts of Australia have historically been subject to regular tropical storms- called cyclones in Australia, hurricanes in the USA.
Here is a graph that looks at the 78 hurricanes to hit the US since 1900. For each one (labelled 1 to 78) on the horizontal axis, the graph shows the days between that storm and its predecessor. The red line shows an estimated “trend” line, although I am not sure that on this type of graph that is very helpful, especially as we do not yet know if this latest “drought” will be followed by a dozen storms in quick succession.
If there is any statistical link between temperature, CO2 and storm occurrences I think it is clear that rising temperatures are associated with fewer storms not more.
