The Met Office is refusing to retract a claim made by a senior meteorologist on BBC Radio 5 Live that storms in the U.K. are becoming “more intense” due to climate change. This is despite admitting in Freedom of Information (FOI) documents that it had no evidence to back up the claim. The Global Warming Policy Foundation (GWPF) noted the “false” claim seriously misled the public and demanded a retraction. The Daily Scepticcovered the story last Thursday and has since contacted the Met Office on three occasions seeking a response. “False information of this kind does much to induce climate anxiety in the population and I am sure you would agree such errors should be corrected by any reputable organisation,” it was noted. No reply was received – no retraction has been forthcoming.
The storm claim was made by Met Office spokesman Clare Nasir on January 22nd and led to an FOI request for an explanation by the investigative journalist Paul Homewood. The Met Office replied that it was unable to answer the request due to the fact that the information “is not held”. Interestingly, the Met Office’s own 2022 climate report noted that the last two decades have seen fewer occurrences of maximum wind speeds in the 40, 50, 60 knot bands than previous decades. The Daily Sceptic report went viral on social media with almost 3,000 retweets on X, while GWPF’s demand for retraction was covered by the Scottish Daily Express.
The lack of action by the state-funded Met Office is very interesting. Extreme weather is now the major go-to explanation for the opinion that humans largely control the climate, despite a general lack of scientific evidence. Backing away from this ‘settled’ narrative risks damaging a potent tool nudging populations across the world towards the collectivist Net Zero political project. Mainstream media usually take care to fudge their reporting of any direct link, using phrases such as ‘scientists say’ and sprinkling words ‘could’ and ‘might’ in the copy. The mistake Nasir made was to forget this basic requirement of broadcast fearmongering.
There appears to be an arrogance around the Met Office, an arrogance it shares with many other organisations and scientists promoting Net Zero …
London, 13 February – The UK Met Office has been accused of seriously misleading the public about climate-driven storms in the UK.
On 22nd January, the day after Storm Isha, a senior meteorologist from the Met Office stated on BBC Radio 5 Live Breakfast that “when we see these storms they are more intense and that’s down to climate change”.
However, after being challenged through a FOI request to provide evidence for the claim that storms have become more intense, the Met Office was forced to admit they have no such evidence.
In its response, the Met Office also referred to its own UK Storm activity report which clearly states that “there is no compelling trend in maximum gust speeds recorded in the UK since 1969.”
We call on the Met Office to publish a full retraction of what is evidently a false and misleading claim.
Met Office: State of the UK Climate 2022 (page 47): “Storm Eunice [in 2022] was the most severe storm to affect England and Wales since February 2014, but even so, these storms of the 1980s and 1990s were very much more severe.”
As all hurricane researchers lament, model predictions of when and where hurricanes will intensify, have not improved much in the past 20 years. As recently as the early 2010s, weather model forecasts failed to predict 88 percent of rapidly intensifying tropical storms. Nonetheless National Public Radio (NPR) has ranted that hurricanes are “intensifying more quickly, turning from less-serious storms to very strong ones in hours or days. Superheated ocean waters hold a lot of extra energy, and a growing storm can draw from that enormous pool.” But such “superheated water” is not widespread as rising CO2 narratives suggest, but found only in very limited regions and usually associated with “barrier layers”.
Hurricanes intensify as they draw “superheated” subsurface waters of 65.5°F or higher. However, when a hurricane’s suction pulls up cooler subsurface waters, the hurricane weakens. This negative feedback naturally limits the intensity of all hurricanes. In the upper panel of the attached graphic, Arnand (2023) illustrates where thin barrier layer exists, hurricane intensity hovers around Category 1. In contrast, where thick barrier layers form, cooler deep waters are prevented from reaching the surface, and instead allow superheated sub-surface waters to cause rapid intensification.
Denser fluids don’t naturally rise above less dense fluids! Barrier layer formation happens wherever freshwater overlays dense salty waters. Although solar heating would normally make subsurface waters less dense and rise to the surface, layers with higher saltiness makes the water more dense which inhibits warm convection. That traps and intensifies the subsurface heat, enabling hurricanes to intensify to Category 5.
Clearly the world has warmed somewhat since 1951, but contrary to what the climate bedwetters claim, the trend in typhoons has been downward – suggesting that a warmer climate leads to less Pacific storms in terms of typhoons formed. This is the opposite of what climate “experts” said would happen.
Next we look at the number of typhoons formed in the Pacific from January to July, going back to 1951:
According to Dr Alexander:
“On almost every kind of extreme weather, with the possible exemption of heatwaves, the evidence for significant changes is scant. But the latest IPCC report has introduced novel ‘attribution’ statistics and now insists that things are getting worse. It’s yet another case of scientists trying to scare the public into compliance.”
Dr Alexander’s paper looks at:
– hot and cold extremes
– coral bleaching.
He concludes that:
“The mistaken belief that weather extremes are worsening because of climate change is more a perception, fostered by media coverage, than reality. The IPCC’s new statistical method is playing an unworthy part in bringing this sorry state of affairs to pass.”
GWPF invited the Royal Society and the Met Office to review this paper, and to submit a response to be published as an appendix to it. No reply was received.
Every year, tropical hurricanes affect North and Central American wildlife and people. The ability to forecast hurricanes is essential in order to minimize the risks and vulnerabilities in North and Central America. Machine learning is a newly tool that has been applied to make predictions about different phenomena. We present an original framework utilizing Machine Learning with the purpose of developing models that give insights into the complex relationship between the land–atmosphere–ocean system and tropical hurricanes. We study the activity variations in each Atlantic hurricane category as tabulated and classified by NOAA from 1950 to 2021. By applying wavelet analysis, we find that category 2–4 hurricanes formed during the positive phase of the quasi-quinquennial oscillation. In addition, our wavelet analyses show that super Atlantic hurricanes of category 5 strength were formed only during the positive phase of the decadal oscillation. The patterns obtained for each Atlantic hurricane category, clustered historical hurricane records in high and null tropical hurricane activity seasons. Using the observational patterns obtained by wavelet analysis, we created a long-term probabilistic Bayesian Machine Learning forecast for each of the Atlantic hurricane categories. Our results imply that if all such natural activity patterns and the tendencies for Atlantic hurricanes continue and persist, the next groups of hurricanes over the Atlantic basin will begin between 2023 ± 1 and 2025 ± 1, 2023 ± 1 and 2025 ± 1, 2025 ± 1 and 2028 ± 1, 2026 ± 2 and 2031 ± 3, for hurricane strength categories 2 to 5, respectively. Our results further point out that in the case of the super hurricanes of the Atlantic of category 5, they develop in five geographic areas with hot deep waters that are rather very well defined: (I) the east coast of the United States, (II) the Northeast of Mexico, (III) the Caribbean Sea, (IV) the Central American coast, and (V) the north of the Greater Antilles.
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.
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.
Alarmist claims cost nothing, and so easily made. Zoe Phin looks at whether the hurricane alarmist claim holds up.
First Zoe looked at the (HURDAT2) data to find out if the first of the two claims (increasing frequency) is true. At first glance it would appear so.
But Zoe asks if the method of measuring the frequency really is sensible and if it maybe weren’t better to measure the amount of time the Atlantic spends in hurricane mode? To find out, Zoe plotted the hurricane hours data and the 10-year moving average:

Every time severe winter weather strikes the United States or Europe, reporters are fond of saying that global warming may be to blame.
The paradox goes like this: As Arctic sea ice melts and the polar atmosphere warms, the swirling winds that confine cold Arctic air weaken, letting it spill farther south.
But this idea, popularized a decade ago [and was the outlandish plotline in The Day After Tomorrow, pictured], has long faced skepticism from many atmospheric scientists, who found the proposed linkage unconvincing and saw little evidence of it in simulations of the climate.
Now, the most comprehensive modeling investigation into this link has delivered the heaviest blow yet: Even after the massive sea ice loss expected by midcentury, the polar jet stream will only weaken by tiny amounts—at most only 10% of its natural swings.
And in today’s world, the influence of ice loss on winter weather is negligible, says James Screen, a climate scientist at the University of Exeter and co-leader of the investigation, which presented its results last monthat the annual meeting of the European Geosciences Union.
Rotating power outages were initiated by the Electric Reliability Council of Texas, or ERCOT, early Monday morning, meaning thousands went without electricity for periods of time as temperatures fell into the teens near Dallas and 20s (about minus 5 degrees Celsius) around Houston.
Austin’s electric utility Austin Energy told residents the outages may be longer than usual, prompting angry social media replies from Texans who said they’d been without power for five or more hours.
“Typical events allow short durations of each outage, but outages are longer if the ERCOT grid requires — which is what we’re seeing in today’s event,” Austin Energy wrote on Twitter.
The utility advised residents to keep their keep their thermostat set to 68 degrees or lower, and to avoid using their oven or washing machine. Businesses were likewise advised to minimize operations to conserve energy.
Following the historic snowstorms of the past few weeks, Japan has been hit again: at least 13 people died and more than 250 were injured as record snowfall blanketed regions along the Sea of Japan coast, according to the latest report by the nation’s Disaster Management Agency.
Among those to have lost their lives were three people in Fukui Prefecture, and four in Niigata Prefecture, all reportedly while trying to remove the snow which topped a whopping 3.13 meters (10.3 feet) in some areas.
According to Japan’s Meteorological Agency (JMA), at least 10 monitoring stations along the Sea of Japan set new all-time 72-hour snowfall records late on Jan. 10, and many more busted all-time low temperature records, including in Furue, Kamigoori, and Kuzakai–with the latter logging a bone-chilling -24C (-11F).
The major winter storm that hit the Eastern United States on Wednesday and Thursday probably prompted some people to ask, “What happened to global warming?”
But although it’s becoming increasingly clear that climate change does have an effect on storms, the relationship can be complex and, yes, counterintuitive. “There were these expectations that winter was basically going to disappear on us,” said Judah Cohen, director of seasonal forecasting at AER, a company that provides information to clients about weather and climate-related risk.
Although winters are becoming warmer and somewhat milder over all, extreme weather events have also been on the increase, and especially in the Northeastern United States, as Dr. Cohen pointed out in a recent paper in the journal Nature Climate Change. From the winter of 2008-9 until 2017-18, there were 27 major Northeast winter storms, three to four times the totals for each of the previous five decades.
Normally between 3 to 4 typhoons form in the Pacific in July. Up to 8 have formed in the past, e.g. on 2017 and 1971. But this year July failed to see a single typhoon form – the first time this has occurred since 1951.

Britain is facing further mayhem over the next 48 hours in the wake of Storm Ciara which battered Britain with winds of up to 100mph causing widespread flooding and travel chaos.
Hundreds of flights were grounded, motorways and main roads shut and trains cancelled and delayed in the wake of a storm that threatens further disruption.
The Met Office warned that ‘exceptional’ gusts of up to 70mph would strike again on Monday and issued snow and ice warnings for large swathes of northern England and almost all of Scotland. The south of England will also be hit for a second day by heavy winds.
Gusts of 97mph were recorded at the Needles off the Isle of Wight while Manchester Airport was buffeted by winds of up to 86mph.
Though the media like to tell their audience that man-made climate change is leading to more extreme weather, the data don’t support it. In fact, one could easily argue that Japan’s climate is more agreeable today.
No trend in long-term annual precipitation
Over the past 100 years, for example, annual precipitation has not trended in an particular direction over the long term, showing rather some cyclical attributes:
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?
Warming temperatures and changes in ocean circulation and salinity are driving the breakup of ice sheets in Antarctica, but a new study suggests that intense storms may help push the system over the edge.
A research team led by U.S. and Korean scientists deployed three moorings with hydrophones attached seaward of the Nansen Ice Shelf in Antarctica’s Ross Sea in December of 2015, and were able to record hundreds of short-duration, broadband signals indicating the fracturing of the ice shelf.
The “icequakes” primarily took place between January and March of 2016, with the front of the ice sheet calving into two giant icebergs on April 7. The day the icebergs drifted away from the shelf coincided with the largest low-pressure storm system the region had recorded in the previous seven months, the researchers say.
Results of the study are being published this week in Frontiers in Earth Science.

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.”
With the devastating Dayton, Ohio tornadoes fresh on our minds, it is useful to examine exactly why (modest) global warming has produced fewer – not more – of such events.
The simple answer is that tornado formation requires unusually cool air.
Very few thunderstorms produce tornadoes. In the hot and humid tropics, they are virtually unheard of. The reason why is that (unlike hurricanes) tornadoes require strong wind shear, which means wind speed increasing and changing direction with height in the lower atmosphere.
These conditions exist only when a cool air mass collides with a warm air mass. And the perfect conditions for this have existed this year as winter has refused to lose its grip on the western United States. So far for the month of May 2019, the average temperature across the U.S. is close to 2 degrees Fahrenheit below normal.
Although many meteorologists and climatologists confirm that there is no data suggesting global warming is causing more frequent and intense tornado and hurricane activity, there is a small but influential alarmist group who claim otherwise. And it’s no surprise who the click-baiting media parrot at maximum volume.
Landfalling hurricanes downward trend
At the 5:45 mark, Joe presents a chart depicting the frequency of US landfalling hurricanes since 1900:
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%)
PROBABILITY FOR AT LEAST ONE MAJOR (CATEGORY 3-4-5) HURRICANE TRACKING INTO THE CARIBBEAN
(10-20°N, 88-60°W) 1) 39% (average for last century is 42%)
Things often calm down after January 1 during El Nino years….but not this year…with the U.S. West Coast from central California to Washington State about to be pummeled by a series of storms. Rain, snow, wind? Plenty for everyone.
A view of the latest infrared satellite imagery shows an amazing line-up of one storm after another stretching way into the Pacific. A traffic jam of storms.
Let’s examine our stormy future, using a series of sea level pressure forecasts from the UW WRF weather forecast models (solid lines are sea level pressure, shading in lower atmosphere temperature).
