Global Hurricane Hours Stable or decreasing

Written by Zoe Phin on June 22, 2021. Posted in Current News

Climate alarmists claim that hurricane frequency is increasing. I have already dealt with this for the Atlantic, here. There was no trend. Today, I will analyze global data.

NOAA sponsors the largest collection of historic hurricane data: IBTrACS (International Best Track Archive for Climate Stewardship). There are 13,545 storms archived going back to 1842, from a total of 14 agencies. My focus will only be on hurricanes, that is: storms that at some time achieved wind speeds at or above 64 knots. Also known as Category 1 or greater.

It is definitely true that the number of detected hurricanes has increased. This is due to better sensing technology, such as aboard radiosondes (1930s), regular transoceanic air travel (1940s), satellites (late 1960s). Due to limitations of older data, it doesn’t make any sense to consider global data before 1950.

Aside from detection, there is also a matter of how one counts the frequency of hurricanes. Does it make sense to count a 6-hour Category 3 storm the same as a 42-hour Category 3 storm?

No, it’s doesn’t make sense. Such a thing would be misleading. But that is what climate alarmists do.

A better thing to do would be to count hours spent in certain wind speed categories:

And this is exactly what I did. Here are the results:

10yr CMA means 10-Year Centered Moving Average.

What does the best hurricane data in the world show?

Category 5 has decreased

Category 4 is cyclic/no-trend

Category 3 had increased, but dropping last 25 years

Category 2 had increased, but dropping last 25 years

Category 1 is cyclic/no-trend

Now we go to category hybrids:

Yeah, pretty much cyclic/no trend.

Category 1,2,3,4,5 is the first image in this post. No trend!

Climate alarmists claim that greenhouse gases create more energy for hurricanes. Well, where is that extra energy for hurricanes?

Update

I added more categories.

There is a decrease in hours spend above 20 knots in the satellite era.

Also a decrease in hours spend above 5 knots. This is not even a breeze.

So, I ask again: where is the extra storm energy from carbon dioxide?
