Hurricanes in 2021 were unprecedented — as in
Globally, 2021 had the fewest hurricanes in the satellite era (1980-2021)
Did you see that reported anywhere?

Good news: a warmer, likely tamer climate, is in the future recent science shows. A new study projects no future increase in tropical storm energy.
Lots of government-funded climate scientists like claiming tropical cyclones are getting worse and that in the future we need to expect one supercharged storm after another – due to man heating the climate with carbon dioxide emissions.
But as we noted yesterday here, Zoe Phin found that hurricanes have not gone along with this dubious doomsday science over the past 25 years. Now a new study confirms things will continue that way.
Today German site Die kalte Sonne (DkS) presents its 49th video on climate and energy, featuring tropical storm energy.
Present vs future scenario
In the segment, DkS cites a new study appearing in the Geophysical Research Letters, where a team of scientists led by Philip Kreussler used three different global climate models to investigate tropical cyclone integrated kinetic energy which is closely associated with their damage potential.
No notable changes

As the year draws to a close, we can note that, despite a busy Atlantic hurricane season, global hurricane activity has actually been well below average:

Inevitably the busy hurricane season this year is getting blamed on global warming:
But first of all, let’s get one thing clear – there was not a record number of hurricanes this year in the Atlantic. There were 13 hurricanes, compared to 15 in 2005:
https://www.aoml.noaa.gov/hrd-faq/#tcs-after-1930
It is true that there were more named storms, which includes tropical storms as well as hurricanes, this season than in any other year, but this is quite meaningless. Over the years, reporting practices have drastically changed, so that more storms are spotted and named now.

PBS News Hour attacked climate science this weekend, publishing alarmist claims about hurricanes and wildfires that defy findings of the United Nations Intergovernmental Panel on Climate Change (IPCC).
In an interview between PBS reporter Hari Sreenivasan and Andrew Freedman, editor of Washington Post’s Capital Weather Gang, the two journalists blamed global warming for severe wildfires and hurricanes.
According to the IPCC, however, there is little or no evidence indicating global warming is impacting hurricanes or drought.

Hurricane Isaias hadn’t even made landfall in the United States before the media began proclaiming Isaias was the result of human-caused climate change.
Not only is there no evidence for such a claim, but hurricane numbers have been declining as global temperatures modestly warm.
Also, even the United Nations Intergovernmental Panel on Climate Change (IPCC) disputes any connection between global warming and hurricanes.

The Atlantic hurricane season has now officially ended, so let’s check the numbers.
https://www.aoml.noaa.gov/hrd/tcfaq/E11.html
http://rammb.cira.colostate.edu/products/tc_realtime/season.asp?storm_season=2019
There have been six hurricanes in total, including three major ones, Dorian, Humberto and Lorenzo. Coincidentally both numbers are the same as the average since 1950.
According to NOAA’s Hurricane Research Division, many hurricanes were missed in the earlier decades. Systematic aircraft reconnaissance began in 1944, but this only covered half of the Atlantic basin, until daily satellite monitoring started in 1966.

I used to be concerned about ‘consensus enforcement’ on the topic of climate change. Now I am concerned about ‘alarmism enforcement.’
Ever since Hurricane Katrina in 2005, any hurricane causing catastrophic damage has been seized upon by climate alarmists as evidence of the horrors of global warming.
As if the record-holding hurricanes from the 1920s through the 1950s never happened.
The catastrophic damage to the Bahamas from Hurricane Dorian is no different. The ‘official’ statement from the alarmist contingent of climate scientists appears to be this article in the Guardian, by Mann and Dessler:
Unfortunately for the alarmists, there are several factors that are getting in the way of the public promotion of the Mann/Dessler narrative:
Alabama-gate: President Trump’s insistence on defending his erroneous statements about the forecasts for Dorian impacting Alabama. A good article summarizing all this was co-authored by one of my former students at Georgia Tech, Brandon Miller [link].
After the Alabama National Weather Service office made a statement that Alabama was not at risk from Dorian, NOAA issued a statement defending President Trump [link].
A WaPo article describes this latest development [link], and the subsequent outrage among scientists and NOAA employees (past and present.
This whole situation is taking the oxygen out of the room in terms of discussions regarding Dorian and global warming. Gotta wonder if this was the strategy?

This month marks the 50th anniversary of Hurricane Camille, the second most powerful to git the US coast. The strongest was the Labor Day Hurricane of 1935.
The NWS has issued this press release:
Hurricane Camille
August 17, 1969Late in the evening on August 17 in 1969, Hurricane Camille made landfall along the Mississippi Gulf Coast near Waveland, MS. Camille is one of only FOUR Category 5 hurricanes ever to make landfall in the continental United States (Atlantic Basin) – the others being the 1935 Labor Day Hurricane, which impacted the Florida Keys; Hurricane Andrew in 1992, which impacted south Florida; and Hurricane Michael in 2018, which impacted the Florida panhandle. (Note: It is worth mentioning that the 1928 San Felipe Hurricane made landfall as a Category 5 Hurricane on Puerto Rico)
Camille ranks as the 2nd most intense hurricane to strike the continental US with 900 mb pressure and landfall intensity of 150 knots. Camille ranks just below the 1935 Labor Day Hurricane with 892 mb and 160 knots, while slightly stronger than Hurricane Andrew with 922 mb and 145 knots and Hurricane Michael with 919 mb and 140 knots. The actual maximum sustained winds of Hurricane Camille are not known as the hurricane destroyed all the wind-recording instruments in the landfall area. Re-analysis data found peak winds of 150 knots (roughly 175 mph) along the coast. A devastating storm tide of 24.6 feet occurred west of our area in Pass Christian, MS.

Politics versus science in attributing extreme weather events to manmade global warming.
If you follow me on twitter, you may have noticed that I was scheduled to testify before the House Oversight and Reform Committee on Jun 12 [link]. The subject of the Hearing is Contending with Natural Disasters in the Wake of Climate Change.
Late on Jun 10, I received an email telling me that the Hearing is postponed (as yet unscheduled). Apparently the Committee finds it more urgent to have a Hearing related to holding the Attorney General and Secretary of Commerce in contempt of Congress [link]. Interesting to ponder that Congressional procedural issues are deemed to be more important than Climate Change.
So I spent all last week working on my testimony (which is why there have been no new blog posts). I hope the Hearing will eventually happen (Michael Mann is also scheduled to testify).
Hurricanes and climate change constitute a major portion of my testimony. You may recall my recent series on Hurricanes & climate change [link]. Specifically with regards to detection and attribution, my bottom line conclusion was:
“In summary, the trend signal in hurricane activity has not yet had time to rise above the background variability of natural processes. Manmade climate change may have caused changes in hurricane activity that are not yet detectable due to the small magnitude of these changes compared to estimated natural variability, or due to observational limitations. But at this point, there is no convincing evidence that manmade global warming has caused a change in hurricane activity.”

Ces deux dernières années ont été marquées par une activité cyclonique supérieure aux moyennes statistiques en Atlantique Nord, notamment en 2017 avec des phénomènes puissants tels Irma et Maria dans les Caraïbes. Cette année, alors que la saison démarre officiellement le 1er juin, nos prévisions sont plus rassurantes avec la perspective d’une activité cyclonique légèrement plus faible que la moyenne.

CFAN predicts an active North Atlantic hurricane season season.
The Atlantic hurricane has begun. We are off to an early start with one wimpy subtropical storm that lasted less than a day, and a small system that is trying to spin up in the Bay of Campeche.
Other forecast providers have begun issuing forecasts:
Climate Forecast Applications Network (CFAN) is going bold, see below. [link] to forecast report.

El Nino and warmer-than-average Atlantic help shape this season’s intensity
From NOAA press release:
NOAA’s Climate Prediction Center is predicting that a near-normal Atlantic hurricane season is most likely this year. This outlook forecasts a 40% chance of a near-normal season, a 30% chance of an above-normal season and a 30% chance of a below-normal season. The hurricane season officially extends from June 1 to November 30.
For 2019, NOAA predicts a likely range of 9 to 15 named storms (winds of 39 mph or higher), of which 4 to 8 could become hurricanes (winds of 74 mph or higher), including 2 to 4 major hurricanes (category 3, 4 or 5; with winds of 111 mph or higher). NOAA provides these ranges with a 70% confidence. An average hurricane season produces 12 named storms, of which 6 become hurricanes, including 3 major hurricanes.

Dr. Philip Klotzbach of Colorado State University writes on Twitter:
Seasonal #hurricane forecast from @ColoradoStateU predicts slightly below-average season: 13 named storms, 5 hurricanes & 2 major (Cat 3+, >=111 mph) hurricanes. Primary reason for slightly below-avg forecast is anticipated continuation of weak #ElNino.
We anticipate that the 2019 Atlantic basin hurricane season will have slightly belownormal activity. The current weak El Niño event appears likely to persist and perhaps even strengthen this summer/fall. Sea surface temperatures averaged across the tropical Atlantic are slightly below normal, and the far North Atlantic is anomalously cool.
Our Atlantic Multi-decadal Oscillation index is below its long-term average. We anticipate a slightly below-average probability for major hurricanes making landfall along the continental United States coastline and in the Caribbean. As is the case with all hurricane seasons, coastal residents are reminded that it only takes one hurricane making landfall to make it an active season for them. They should prepare the same for every season, regardless of how much activity is predicted.
PROBABILITIES FOR AT LEAST ONE MAJOR (CATEGORY 3-4-5) HURRICANE LANDFALL ON EACH OF THE FOLLOWING COASTAL AREAS:
1) Entire continental U.S. coastline – 48% (average for last century is 52%)
2) U.S. East Coast Including Peninsula Florida – 28% (average for last century is 31%)
3) Gulf Coast from the Florida Panhandle westward to Brownsville – 28% (average for last century is 30%)

I am pleased to report that the GWPF have now published my latest paper on hurricane trends.
It demonstrates that, contrary to popular myth, hurricanes are not getting more frequent or more powerful.
The paper is based throughout on official data, scientific papers and IPCC reports.
Here is the Executive Summary:

by Kam-biu Liu & Miriam L. Fearn, September 2000, in QuaternaryResearch
Sediment cores from Western Lake provide a 7000-yr record of coastal environmental changes and catastrophic hurricane landfalls along the Gulf Coast of the Florida Panhandle. Using Hurricane Opal as a modern analog, we infer that overwash sand layers occurring near the center of the lake were caused by catastrophic hurricanes of category 4 or 5 intensity. Few catastrophic hurricanes struck the Western Lake area during two quiescent periods 3400–5000 and 0–1000 14C yr B.P. The landfall probabilities increased dramatically to ca. 0.5% per yr during an “hyperactive” period from 1000–3400 14C yr B.P., especially in the first millennium A.D. The millennial-scale variability in catastrophic hurricane landfalls along the Gulf Coast is probably controlled by shifts in the position of the jet stream and the Bermuda High.

Hurricane Florence made landfall on Friday in North Carolina, bringing heavy rains and flooding. But before the storm touched down in the U.S., scientists and news outlets were already linking the storm to global warming.
However, not all scientists agree that man-made warming is making hurricanes, including Florence, bigger, slower and wetter as is often claimed in the media.
Climatologist Judith Curry called efforts by the “mainstream climate community” to link Florence to man-made global warming “woefully inadequate and misleading to scientists, the public and policymakers.”

by Roy W. Spencer, September 15, 2018 in USAToday
Even before Hurricane Florence made landfall somewhere near the border of North and South Carolina, predicted damage from potentially catastrophic flooding from the storm was already being blamed on global warming.
Writing for NBC News, Kristina Dahl contended, “With each new storm, we are forced to question whether this is our new, climate change-fueled reality, and to ask ourselves what we can do to minimize the toll from supercharged storms.”
The theory is that tropical cyclones have slowed down in their speed by about 10 percent over the past 70 years due to a retreat of the jet stream farther north, depriving storms of steering currents and making them stall and keep raining in one location. This is what happened with Hurricane Harvey in Houston last year.
But like most claims regarding global warming, the real effect is small, probably temporary, and most likely due to natural weather patterns …
