170 years of “Completely no development” when it comes to hurricane depth / frequency – watts with that?

If you repeat a truth enough times, it will stay that way.
Comprehensive data analyzes again show no connection between rising CO2 and the intensity or frequency of tropical storms. It is important to repeat this regularly.
Zoe Phin
The latest comes from statistics expert Zoe Phin, who is investigating the alarmists’ claim that rising carbon emissions are leading to more frequent and intense hurricanes in the Atlantic.
Alarmistic claims are free and easy to make. Zoe Phin checks to see if a hurricane alarmist’s claim stands.
frequency
First, Zoe examined the (HURDAT2) data to see if the first of the two claims (increasing frequency) is true. At first glance, it seems that way.
But Zoe asks if the method of measuring frequency really makes sense and if maybe it wouldn’t be better to measure the time the Atlantic spends in hurricane mode. To find out, Zoe recorded the hurricane hour data and the 10-year moving average:

From the data, Zoe concludes: “The amount of Hours of hurricanes per year shows absolutely No trend! ”
intensity
Next, she looks at the second claim: the hurricane’s intensity is getting worse and worse – and thus possibly more destructive.
To find out, Zoe reasonably uses the hurricane’s lowest pressure as a proxy. “The lower the pressure, the more intense the storm.”
It records the data for all hurricanes, the corresponding lowest pressure values:

Not a trend in 170 years!
There was an upward trend from 1970 to around 2005, but then the intensity decreased, although CO2 concentrations in the atmosphere steadily increased. The high around 2005 was very similar to the 1920s, about 100 years ago, when CO2 was much lower.
Zoe summarizes her findings:
In almost 170 years there has been absolutely no trend in hurricane intensity!
Clearly, climate alarmists are wrong about Atlantic hurricanes. “
Confirmed by other independent results
Of course, Zoe’s results are no surprise to those who look at the data.
Other leading scientists have come to the same conclusions: Hurricanes have not gotten stronger or more frequent. For example, Klotzbach et al. (2018):
Or Dr. Ryan Maue on global cyclone activity since 1970, the Dr. Roger Pielke Jr quotes:
Or Zhao et al. 2018 about cyclones in the western North Pacific:
Japan sees cyclone downtrend
Another example comes from the Japanese NTZ employee Kirye, who recorded data from the Japan Meteorological Agency (JMA) on typhoons in the Pacific:
Data source: JMA
Alarmists obviously in la-la-land
Arguing with alarmists about this is a waste of time. The data is in and the results are pretty clear: CO2 doesn’t drive much, much less typhoons.
