You get a similar problem with saltwater intrusion where, yes, it's never not been a phenomenon but now it's affecting a lot more people than it used to:

This is the conventional wisdom, and it is completely falsified by the actual data that I linked to. I wrote a python script to go process and plot it, and there has been zero increase in Cat 1, 2, 3, or 4 storms hitting the US since 1851 (there are only 4 Cat 5s listed total).
Try it for yourself.
It’s like saying the UV radiation hitting the earth is the same as it was historically so therefore an ozone hole in Australia didn’t exist and cataracts can’t be higher there.
You have to diagnose a problem correctly in order to have a chance at solving it.
It’s great you’re bringing data to the table but you’re overstating its validity to the assertion dramatically.
Finally I’d note you’re asserting an analysis you’ve done without providing the data, method, or any reproducibility. So while you might personally feel you’ve done an accurate job, your assertions are citing exclusively yourself, against hidden methods, making it of no more quality than a puff piece article citing research without citation that you’re arguing against.

The analysis is easy: copy and paste the data from that link into a new text file, then write a python script that goes through it and counts the number of Cat 1, 2, 3, 4 & 5 hurricanes that make landfall per year (the "Highest Saffir-Simpson U.S. Category" column), and then make the plots: I used gnuplot. You can then do fits to the data if you'd like, but the flat trend lines over the last 175 years are obvious.
I encourage you to not trust me and to do it yourself, but I'm also happy to share my script, let me know.
As far as the hurricane trajectory trend lines go, they are clearly highly stochastic: check out e.g. both the spaghetti plot predictions for various storms from previous years, and ask google for a map of where they grow (grew...) oranges in Florida.
Do actual climate scientists claim we're getting more, and stronger, hurricanes now than we did before?
At some point the discourse changed from “just because it’s a cold winter doesn’t mean that global warming isn’t happening” to “every hurricane/wildfire is due to climate change” and it’s ridiculous.
I honestly think a lot of young people don’t realize that while climate change is probably real our weather and variability hasn’t changed that much - yet, at least.
"Much" is one of those vague words, where it's true and false depending on your meaning.
If you live on any of the transition zones between climates, as I did growing up, it is directly visible: My experience of snow in the south coast of the UK was almost entirely in the early years of my childhood, and family photos of my older siblings show that they had even more than me. My parents had experiences of even deeper and longer cold, with ponds freezing completely solid, not just a layer of ice on the top.
I can easily imagine someone who lives in the parts of the US where all the winter urban snow photos come from, may not notice the loss of a 1-2 centimetres out of 100cm of snowfall, but when it's your last centimetre, it's much easier to spot.
The general line is that climate change has probably increased the amount of rainfall associated with hurricanes, possibly the severity of hurricanes (due to sea level rise and warmer water) but there isn't good evidence that it has increased the frequency of hurricanes.
For hurricanes this seems especially problematic because the historical categorization system is based on radar-observed width of the storm. "More energy" means that the categories stay the same over time, but every category is getting worse (more rainfall, heavier/faster winds, further travel, higher damage).
As with so many statistical phenomenon, it's also a reminder to be careful what metrics you are trying to compare. Comparing just the hurricane categories to historic values may just be the exact sort of wrong metric, for these "more energy" concerns.
Now I'm confused again, because OP used data going back to 1851. We didn't have radar in the 19th century.
The original point still stands that Hurricanes are defined by only the one metric and other metrics have room to grow bigger as the category stays the same:
> The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 rating based only on a hurricane's maximum sustained wind speed. This scale does not take into account other potentially deadly hazards such as storm surge, rainfall flooding, and tornadoes.
Climate science is also highly political, and seems to have a big economic impact…
It seems many are jumping to biases about climate change without reviewing the data as you did.
And the article should've been written with more nuance.
The idea that climate change caused hurricanes which spread insects is not impossible but seems unlikely. I don't think the statistical methods exist to prove it.
I love the stories about people in FL self-insuring now because it's cheaper to repair drywall than pay premiums.
Now, I see a slate of historical hurricanes in FL from 2004-05 that hit the Ridge area. This contradicts the article as these weren't baby storms.
The issue is clearly the rise of this blight bacteria that has made the groves less resilient to storms and has weakend production.
Just not true with their phrasing.
edit:
for clarity, the author referenced 2017+ vintage hurricanes as if nothing of their intensity had hit before: Irma (2017), Ian (2022), Idalia (2023), Helene (2024), and Milton (2024). None of these got beyond cat 4. Meanwhile there were certainly other hurricanes that were cat4 that hit the groves in 2004-05.
