2023 hurricane season far less active than predicted

Written by Climate Discussion Nexus on December 14, 2023. Posted in Current News

In the upside-down world of climate science, where every weather event is caused by ‘climate change’ and there is a voracious need for weather disasters to prove just how bad things are getting, nothing cheers up the activists like a large catastrophic hurricane or two

The more homes get knocked over and the more fatalities the better, and if you can tally up at least a billion dollars in damages then it’s truly an occasion for celebration.

But as Roger Pielke Jr. notes, that the 2023 US hurricane season came and went and there was only one hurricane making landfall, despite forecasts of many more.

Spare a thought for the poor alarmists whose hopes were dashed once again.

The one hurricane, Idalia, made landfall as a Category 3 storm.

Pielke Jr.’s graph of the long term trend of landfalling hurricanes is as follows:

Yup, that’s trending down. As the late Dr Tim Ball said many times, and Richard Lindzen continues to say; in a warmer world you get LESS bad weather not more.

Every meteorologist worth his salt knows this, but almost none will stand up and say it publicly, for fear of being sacked or losing their funding.

As for major storms (Cat 3 or higher), here’s that graph:

Note the total absense of major landfalling hurricanes between 2006 and 2017.

Yes we have no trend. Normalized damage losses (adjusted for inflation and income growth) show no secular change from 1900 to 1970, after which they rise for reasons Pielke Jr. doesn’t explain.

But he also notes that 2023 will be exceptionally low in the context of the modern record because there was only one hurricane.

Finally Pielke Jr. takes stock of the hurricane forecasts for the 2023 season and points out that 8 of the 11 predicted it would be worse, or better if you’re an alarmist, than they would have done if their authors had just used the historical average.

So almost all the hurricane models have a built-in bias toward the future being stormier than the past.

Which doesn’t mean the future will actually be just as stormy, or less so.

It simply means that whatever it turns out to look like, we can’t claim to understand what is driving it because the scientific models make predictions that turn out to be unreliable.

Unless you prefer to avoid catastrophes and costly weather disasters, in which case you’re (a) in luck, and (b) normal.
