Critical Examination of Hurricane Intensification Predictions

by J. Steele, Oct 1, 2023 in WUWT

Why climate models not yet worth their salt!

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.

THE TRUTH ABOUT WEATHER EXTREMES What the Past Tells Us

by Alexander, Sep 2023 , in GWPF

Executive summary

This report refutes the popular but mistaken belief that today’s weather extremes are more common and more intense because of climate change, by examining the history of extreme weather events over the past century or so. Drawing on newspaper archives, the report presents multiple examples of past extremes that matched or exceeded anything experienced in the present-day world. That so many people are unaware of this shows that collective memories of extreme weather are short-lived.

Heatwaves of the last few decades pale in comparison to those of the 1930s – a period whose importance is frequently downplayed by the media and environmental activists. The evidence shows that the record heat of the 1930s was not confined to the US Dust Bowl, but extended throughout much of North America, as well as other countries such as France, India and Australia.

Major floods today are no more common nor deadly or disruptive than any of the thousands of floods in the past, despite heavier precipitation in a warming world (which has increased flash flooding). Many of the world’s countries regularly experience major floods, especially China, India and Pakistan.

Severe droughts have been a continuing feature of the earth’s climate for millennia, despite the brouhaha in the mainstream media over the extended drought in Europe during the summer of 2022. Not only was the European drought not unprecedented, but there have been numerous longer and drier droughts throughout history, including during the past century.

Hurricanes overall actually show a decreasing trend around the globe, and the frequency of landfalling hurricanes has not changed for at least 50 years. The deadliest US hurricane in record- ed history, which killed an estimated 8,000 to 12,000 people, struck Galveston, Texas over 100 years ago in 1900.

Likewise, there is no evidence that climate change is causing tornadoes to become more frequent and stronger. The annual number of strong (EF3 or greater) US tornadoes has in fact declined dramatically over the last 72 years, and there are ample examples of past tornadoes just as or more violent and deadly than today’s.

Wildfires are not increasing either. On the contrary, the area burned annually is diminishing in most countries. Although wildfires can be exacerbated by other weather extremes such as heatwaves and droughts, those extremes are not on the rise as stated above.

The perception that extreme weather events are increasing in frequency and severity is primarily a consequence of modern technology – the Internet and smart phones – which have revolutionised communication and made us much more aware of such disasters than we were 50 or 100 years ago. The misperception has only been amplified by the mainstream media, eager to promote the latest climate scare. And as psychologists know, constant repetition of a false belief can, over time, create the illusion of truth. But history tells a different story.

Climate Emergency Not Supported by Data, Leading Italian Scientists Say

by C. Morrison, Sep 15, 2022 in ClimateChangeDispatch

Four leading Italian scientists have undertaken a major review of historical climate trends and concluded that declaring a ‘climate emergency’ is not supported by the data.

Reviewing data from a wide range of weather phenomena, they say a ‘climate crisis’ of the kind people are becoming alarmed about “is not evident yet”. [bold, links added]

The scientists suggest that rather than burdening our children with anxiety about climate change, we should encourage them to think about issues like energy, food, and health and the challenges in each area, with a more “objective and constructive spirit” and not waste limited resources on “costly and ineffective solutions.”

During the course of their work, the scientists found that rainfall intensity and frequency are stationary in many parts of the world.

Tropical hurricanes and cyclones show little change over the long term, and the same is true of U.S. tornadoes. Other meteorological categories including natural disasters, floods, droughts, and ecosystem productivity show no “clear positive trend of extreme events.”

Regarding ecosystems, the scientists note a considerable “greening” of global plant biomass in recent decades caused by higher levels of carbon dioxide in the atmosphere. Satellite data show “greening” trends over most of the planet, increasing food yields and pushing back deserts.

The four scientists are all highly qualified and include physics adjunct professor Gianluca Alimonti, agro-meteorologist Luigi Mariani, and physics professors Franco Prodi and Renato Angelo Ricci. The last two are signatories to the rapidly growing ‘World Climate Declaration’.

This petition states that there is no climate emergency and calls for climate science to be more scientific. It also calls for the liberation from the “naïve belief in immature climate models.” In the future, it says, “climate research must give significantly more emphasis to empirical science.”

‘Extreme’ weather events attributed by climate models – somehow – to anthropogenic global warming are now the main staple of the climate alarmist industry.

As the Daily Sceptic reported on Monday, Sir David Attenborough used a U.K. Met Office model forecast in the first episode of Frozen Planet II to claim that summer Arctic sea ice could be gone within 12 years.

Canadian Fires Defy Alarmist Claims, Continue Downward Trend

by P. Gosselin, Aug 30, 2023, in ClimateChangeDispatch

Unusual weather situations are always the hour for attribution researchers these days.

Canada is suffering from forest fires again this year. The reason is the persistent drought. [emphasis, links added]

According to a study, climate change has doubled the probability of forest fires in Canada:

Extreme wildfire conditions in Canada have been fueled by intense, spatially extensive and persistent fire-conducive weather conditions, known as fire weather, which has been observed since the beginning of May throughout the country. Canada has experienced its warmest May-June period since 1940, beating the previous record set in 1998 by a huge margin (0.8°C).

At the national scale, relative humidity was also very low. The warm and dry conditions, together with continuous southeasterly winds fueled extensive fire spread in Alberta, British Columbia, central Saskatchewan and southwestern portions of the Northwest Territories.

There are at least 17 direct fatalities linked to the fires, more than 150,000 people have been evacuated, and at least 200 structures, including homes, were damaged in the fires (AP News, 2023).

The Canadian wildfires have severely impacted air quality locally in Canada, and in the neighboring United States with Air Quality Index (AQI) values frequently exceeding safe levels in the Midwest and northeast USA, and in some cases approaching record levels (e.g. on June 7th AQI reached 341 in New York City, considered hazardous for all residents) (CNBC, 2023).

Similarly, in southern Ontario, including the cities of Ottawa and Toronto, air quality reached the ‘very high risk’ level forcing officials to cancel public events and reduce hours for outdoor public services. Schools remained closed for several days in many states, including Nova Scotia, New York, New Jersey, and Connecticut.”

Trend defies alarmist claims

However, the country’s official wildfire statistics do not show this suspected trend. Statista lists them.

Strictly speaking, the trend in the number of fires is decreasing through 2022. [The numbers will rise again in 2023 given almost 6,000 fires were counted by August 23, 2023.]

But that will still be below the 2006 figures.

Summer: The Best Of Times For Climate Alarmists

by G. Wrightstone, Aug 25, 2023 in ClimateChangeDispatch

August and September are great months to be a professional climate alarmist like Dr. Michael Mann of the University of Pennsylvania.

You have hurricanes making landfall, wildfires seemingly everywhere, the odd F-4 tornado wreaking devastation, and you can pretend that these [events] never happened before we started adding CO2 to the atmosphere. [emphasis, links added]

Plus, you have virtually all the media and a host of “environmental” groupsparroting every seemingly scientific observation without question.

Yes, alarmists find it best to use their time during the hazy hot days of summerlinking every possible weather event to our use of fossil fuels and that demon molecule, CO2.

They must do this in order to instill the fear required to impose economically crippling new taxes or restrict citizens’ freedom to choose what car, dishwasher, stove, showerhead or washing machine to purchase.

Right now, with wildfires in Canada and Greece and the tragic fire in Lahaina, Maui, the focus is on linking supposed man-made warming to these events and characterizing them as unprecedented.

Are they really extraordinary and increasing?

NASA reports that between 2003 and 2019, the global area burned has dropped by roughly 25 percent.

In addition, the Copernicus Atmosphere Monitoring Service reports that according to satellite data, the year 2020 was one of the least active years since records began in 2003.

21st Century Global Disasters

by P. Homewood, Aug 13, 2023 in NotaLotofPeopleKnowThat

A new peer-reviewed paper out this week by Alimonti and Mariani asks whether global disasters have increased. Their answer is that they have not (and if the name sounds familiar, it is the same Alimonti whose paper is being improperly retracted — more fresh info on that in the coming days).

As I read their paper today I noticed that the time series they reported from the EM-DAT databaselooked a bit different than that I had last explored and presented here at THB late last year. So today I downloaded the most recent data from EM-DAT, and indeed there has been some changes to the most recent three years, presumably due to late entries into the database (however I will enquire as all post-hoc dataset updates should be documented). EM-DAT has been funded since the late 1990s by the U.S. Agency for International Development.

Below is the updated time series of global hydrological, climatological and meteorological disasters in the EM-DAT database, along with the linear trend, over the period 2000 to 2022.

Stop Blaming Fires In Canada, Greece, And Now Maui On Climate Change

by Dr M. Wielicki, Aug 10, 2023 in ClimateChangeDispatch

There is currently a wildfire on the Hawaiian island of Maui that has forced evacuations and led some people to flee into the ocean for safety.

The fires are being driven by strong winds and dry air, primarily associated with Hurricane Dora passing hundreds of miles to the south.

The fires have reportedly burned structures and prompted evacuations in Maui, particularly in the Upcountry and Lahaina areas. Lahaina is a popular tourist destination on the island’s northwest side. [emphasis, links added]

Multiple evacuation orders are in effect for the island and there are no details yet on the extent of the damage.

A dozen people were rescued by the Coast Guard after jumping into the ocean to reportedly avoid the flames. Acting Governor Sylvia Luke issued an emergency proclamation on behalf of Gov. Josh Green.

As with every natural disaster, the links to climate change were made almost immediately.

However, attributing a single wildfire directly to climate change is an oversimplification of the myriad factors at play.

Wildfires can be influenced by various causes, including local weather, forest management, human activities, and natural events like hurricanes passing and changing wind patterns.

Historically, the climate has always exhibited natural variability with periods of extreme conditions. It’s crucial to differentiate between this natural variation and the changes driven or intensified by human activities.

Of course that didn’t stop folks from attributing the fires in Maui directly to anthropogenic climate change…

Hawaiian Fires: Fueled by Invasive Grasses, a Wet Spring and Human Ignition Sources

by J. Steele, Aug 11, 2023 in CO2Coalition

The Maui fire would have devastated Lahaina in a colder or warmer climate. It would have devastated Lahaina in high or low CO2 concentrations. The key is managing the dead grasses that become flammable in just hours. Climate change was irrelevant. Declaring a climate emergency to reduce fossil fuels is a useless remedy that only misdirects funds that will be needed to better manage a fire-prone landscape.

The massive destruction and loss of life in Lahaina, Hawaii due to the recent wildfire has evoked tremendous compassion and concern from around the world for the people of Lahaina. I can’t comprehend the intense pain now being felt by the people who have lost loved ones, lost homes, and lost all their belongings. So how can such a tragedy be prevented from ever happening again?

First, according to meteorologist Cliff Mass, Hawaii is one of the most fire-prone states in the U.S. (see Figure 1 for some historical fires).

Lightning is rare on Maui. Fewer than thirty thunderstorms rattle across the Hawaiian Islands each year, and most occur during January and February. Accordingly, there have been no reports of an August lightning strike, so it seems doubtful this tragic fire was started naturally.

According to Hawaii Wildfire Management Organization, 98% of all Hawaiian fires are started by people, of which 75% are due to carelessness.  Thus, a Smokey-the-Bear type campaign that “only you can prevent forest fires” would help raise people’s consciousness, especially newcomers.  As retirees flock to Hawaii seeking the health benefits of a warmer climate, the population has tripled since 1980, which only increases the probability of a careless fire being started.

If started by an electrical spark, efforts to secure a vulnerable electrical grid is required. Sadly, the remaining fires have been suspiciously ignited by arsonists, and arson is nearly impossible to prevent.

However, there are other precautions that Hawaiians can take to prevent the rapid spread of fire that caught so many people in Lahaina by surprise.  Dr. Clay Trauernicht, a professor of natural resources and environmental management at the University of Hawaii, notes wildfires have quadrupled in Hawaii in recent decades.  We agree with his assessment that unmanaged, nonnative grasslands that have flourished in Hawaii after decades of declining agriculture have provided the fuel for more rapidly spreading and extensive wildfires.

As Maui’s pineapple and sugar cane plantations were abandoned, they became dominated by invasive annual grasses that flourish in disturbed soils. Fire experts categorize such small diameter grasses as 1-hour lag fuels, meaning that within half a day of dry weather, these grasses become highly flammable, allowing fires to rapidly spread in even moderate winds. Annual grasses typically die during the dry seasons. Maui’s rainless period typically lasts from about May 25 to July 15.

Furthermore, Lahaina is situated on the leeward side of Maui’s mountains. These highlands wring out the moisture carried by the trade winds, with only 15” of rain falling in Lahaina compared to 300” on the mountains to the east. Thus, Lahaina’s surrounding grassland vegetation is primed each summer to rapidly burn once ignited.

What Is A 1000 Year Flood?

by P. Homewood, Apr 18, 2023 in NotaLotofPeopleKnowThat

We’ve all heard the terminology. An extreme event happens — a flood or heat wave — and soon after it is characterized as a “1,000-year event” (or it doesn’t have to be 1,000, it could be any number). This week I watched one of the world’s most visible climate scientists, Michael E. Mann, go on national TV and in process show that he had no idea what the concept actually means.

Let’s start by correcting that climate scientist who expressed a popular misconception (about which climate scientists should know better). A 1,000-year flood does not refer to a level of flooding that comes around every 1,000 years.

Climate Expert: The Misinformation In The IPCC, Part 1

by R. Pielke, Mar 29 2023 in ClimateChangeDispatch

Today, in the first of two posts, I explain how the IPCC made several misleading claims related to tropical cyclones.

The IPCC’s failures are both obvious and undeniable.

I will walk you through them in detail. Once again, I conclude that the IPCC needs reform. Mistakes can creep into massive assessments, to be sure, but the failures I document below are unacceptable. [emphasis, links added]

The first failure never rose above the depths of Chapter 11 of its AR6 Working Group 1 (WG1) report. The second is a bit technical and is much more significant – having made its way into the Summaries for Policymakers (SPMs) of both WG1 and the Synthesis Report released last week.

Before proceeding, let me reiterate that the IPCC is not just one report or one group of people. It is many things and comprised of many different people. Its products are of uneven quality, and even individual chapters in the same report can be of very different scientific quality.

For instance, in general, IPCC AR6 WG1 did a nice job on the physical science aspects of extreme weather, whereas IPCC AR6 WG2 was chock full of massive problems. …snip…

Rainfall, Cyclone Data Show No Clear Upward Trend, Contradict IPCC Claims

by P. Gosselin, Mar 19, 2023, in NoTricksZone

Feel helpless when trying to assess the veracity of “climate doom is looming” claims? Don’t give up trying to understand the relevant basics because you don’t need to be a scientist to do so.

There is a rather simple way to get an idea about what this is all about. Even without a scientific background, most people have at least a good common sense. And that’s all it takes to get a grasp of how energy flows back and forth between earth’s surface and the skies.

Today in Part 5, we look at the linkage between the allegedly CO2-driven rise of air and sea surface temperatures on the one side and the disconnect between these increases and their strangely weak to insignificant impact on rainfall and hurricane intensity”.

Preceding chapters see Part 1 1), Part 2 2), Part 3 3), Part 4 4).

Variability of cloud effects vs “greenhouse gas” effects

In the last chapter, we have seen that there are some discrepancies between the global warming trend as claimed by the official climate science and the local evolution of rainfall, which should be a direct consequence of higher temperatures since this causes more evaporation. This seems not to be the case e.g. for Germany, see Fig. 1:

Intense, Long-Lasting Heatwaves Unfolding At The Bottom Of The Ocean

by G. Dickie, Mar 16, 2023 in ClimateChangDispatch

Heatwaves unfolding on the bottom of the ocean can be more intense and last longer than those on the sea surface, new research suggests, but such extremes in the deep ocean are often overlooked.

A team of scientists with the U.S. National Oceanic and Atmospheric Administration has conducted the first assessment of marine heatwaves along North America’s continental shelves.

They found that these bottom heatwaves ranged from 0.5 degrees Celsius to 3C warmer than normal temperatures and could last more than six months — much longer than heatwaves at the surface.

“We simply don’t have a ton of instruments on the ocean bottom along continental shelves,” said study co-author Dillon Amaya, an NOAA climate scientist. “The ocean is a powerful thing. It destroys instruments that we have in the water for too long.”

Surface heatwaves can be picked up by satellites and can result in huge algal blooms.

Executive summary

It is widely believed that hurricanes are getting worse as a consequence of climate change. This belief is fuelled by the media and some politicians, particularly when a bad storm occurs. This be- lief is reinforced because the damage caused by hurricanes is much greater nowadays, thanks to increasing populations in vulnerable coastal areas and greater wealth more generally.

But is this belief correct, or is it a misconception? This study has carefully analysed official data and assessments by hurricane scientists, and finds:

• 2021 and 2022 recorded the lowest number of both hurricanes and major hurricanes glob- ally for any two year period since 1980.

• The apparent long-term increase in the number of hurricanes since the 19th century has been due to changes in observational practices over the years, rather than a real increase.

• Data show no long-term trends in US landfalling hurricanes since the mid-19th century, when systematic records began, either in terms of frequency or intensity.

• Similarly, after allowing for the fact that many hurricanes were not spotted prior to the sat- ellite era, there are no such trends in Atlantic hurricanes either.

  • Globally there are also no trends in hurricanes since reliable records began in the 1970s.
  • Evidence is also presented that wind speeds of the most powerful hurricanes may now be overestimated in comparison to pre-satellite era ones, because of changing methods of meas- urement.

• The increase in Atlantic hurricanes in the last fifty years is not part of a long-term trend, but is simply a recovery from a deep minimum in hurricane activity in the 1970s, associated with the Atlantic Multidecadal Oscillation.

These findings are in line with those of hurricane scientists generally, as well as official bodies such as NOAA and the IPCC.

Climate Expert: What The Media Won’t Tell You About Tornadoes

by R. Pielke, Feb 13, 2023 in ClimateChangeDispatch

This is the latest post in an ongoing series, titled “what the media won’t tell you about…”, which is motivated by the apparent systemic inability of the legacy media to play things straight when it comes to extreme weather and disasters.

Climate change is real and important, but its importance is not an excuse for the pervasive climate misinformation found across the legacy media. [emphasis, links added]

Here are the previous installments in the series, which are among my most popular posts and which have gone unchallenged.

What the media won’t tell you about…

Today’s post focuses on U.S. tornadoes. This year so far has seen a lot of tornadoes — 178 were reportedthrough February 11th, the 2nd most since 2005 and well above the 2005-2022 mean of 66 to date.

Of course, nowadays wherever there is extreme weather, journalists rush to claim a connection to climate change no matter what the science actually says.

For instance, after a tornado outbreak last month, the Associated Press reported that the tornadoes had been “juiced by climate change.”

Similarly, The Washington Post said that in the past it was difficult to tie tornadoes to climate change but now, “science is accumulating to support the linkage.”

Neither reported any of the data and science I share below. So, let’s take a look

The Great Famine of the 21st Century

by D. Siegel,  Nov 29, 202 in Shortfall

…

…

The true tragedy

The problem isn’t the future. The problem is what we’re doing right now. Today, humans spend more than $1 trillion every year on decarbonization, which will most likely have no measurable effect on our future climate. But it does raise the price of energy, and the current virtue-signaling environment prevents people in the developing world from reaching the standard of living we take for granted.

Today, life expectancy in sub-Saharan Africa is 60 years — the same as it was in the United States in 1935. Today, about 60 percent of sub-Saharan people are farmers — the same as in the US in 1860. About 500 million people in Africa live in extreme poverty. According to the World Bank, half the countries in Sub-Saharan Africa have poverty rates higher than 35%.

And yet, that same World Bank won’t lend them money to build a reliable energy grid. The United Nations and the World Economic Forum are forcing Africans to install solar and wind projects that can’t help them cook dinner, so they continue to burn trees, charcoal, and dung, destroying forests and dying of lung diseases. They are — right now — being forced to live lives we lived in 1850.

Yes, you say, but prices of solar panels are coming down! Imagine you have a car that drives really well whenever the sun is shining or the wind is blowing. No batteries, nothing, it just works. It’s not even that expensive, and it is magically zero emission. Now, can you get rid of your regular car? Or do you need to have your own back-up car for whenever the sun isn’t shining or wind isn’t blowing? You might think you could just rent or use an Uber then, but that’s exactly when everyone else needs a car, too, so you actually have to maintain your existing car, pay the insurance, make sure it’s always available, for those times when your renewable car isn’t possible and the Uber is taken. That’s twice as many cars, no matter who owns them. That’s not “sustainability.”

Summary

As you have just learned, we live in the safest century to be alive. We are more protected against natural disasters than ever. And we are being lied to about CO2 and climate.

This isn’t easy for a lot of people to hear. It has become a matter of tribal and political identity. I know. In 1991, I wrote a book about how CO2 was changing the climate. But then I dug deeper and realized not everything was as it seemed. When I started to tell others the science wasn’t settled, I lost quite a few friends.

An Inconvenient Tree: Is Climate Change Driving Worse Floods

by E. Worrall, Nov 27, 2022 in WUWT

Does evidence of past extreme floods invalidate claims that climate change is making floods worse?

…

…

 

Could volcanic activity be a contributor to major floods in Australia? Australia is on the South Western edge of the Ring of Fire. While the Australian mainland is not very volcanically active, there have been some spectacular eruptions in our neighbourhood, such as the infamous Krakatoa eruption in 1883, or the 1815 Tambora Eruption, which is blamed for causing famine in the United States in 1816, “The Year Without a Summer”.

A notable volcanic eruption occurred at the start of 2022 – The Hunga Tonga eruption. JoNova published an intriguing comparison between the volcanic ash distribution from the Hunga Tonga eruption in January 2022, and 2022 rainfall anomalies across Australia. Hunga Tonga was light on sulphates, but the blast threw unprecedented amounts of water into the stratosphere. Where I live, on the Southern edge of the volcanic debris distribution, we’ve had some spectacular sunsets over the last year.

The apparent overlap between rainfall anomalies and volcanic debris could be a coincidence – but the comparison is visually intriguing.

97% Consensus on Climate Change? Survey Shows Only 59% of Scientists Expect Significant Harm

by WUWT, Nov 9, 2022

Humans are likely causing some warming, but substantial scientific disagreement exists on whether there will be significant impacts

ARLINGTON HEIGHTS, IL (November 8, 2022) – A new poll of scientists conducted by Fairleigh Dickinson University found that only 59 percent of respondents think global climate change will cause “significant harm” to the “living conditions for people alive today.” That is far short of the “97 percent consensus” narrative pushed by climate alarmists and their media allies across the globe.

The survey, conducted in September and October 2022 by Fairleigh Dickinson University and commissioned by The Heartland Institute, polled only professionals and academics who held at least a bachelor’s degree in the fields of meteorology, climatology, physics, geology, and hydrology.

The key question of the survey asked: “In your judgement, what will be the overall impact of global climate change on living conditions for people alive today, across the globe?” Fifty-nine percent said “significant harm.” Thirty-nine percent said either “significant improvement,” “slight improvement,” “no change,” or “slight harm.” Two percent were not sure.

Among respondents with the most experience – those at least 50-years-old – less than half expect significant harm for people alive today. Scientists 30-years-old and younger were the only age group for which more than 60 percent expect significant harm.

Like prior surveys of scientists, the new poll shows the vast majority of scientists agree the planet is warming. On average, respondents attributed 75 percent of recent warming to human activity. More importantly, scientists disagree among themselves on whether future warming will be much of a problem.

The poll also found only 41 percent of respondents believe there has been a significant increase in the frequency of severe weather events. The majority say there has been no change or only a slight increase.

In reality, objective data show hurricanes, tornadoes, wildfires, drought, and other extreme weather events have become less frequent in recent decades.

Let’s Talk About Real Climate Cataclysms

by P. Driessen, Oct 26, 2022 in ClimateChangeDispatch

The climate crisis! Save our planet! Stop using fossil fuels! The ranting never ends.

Present data show that hurricane frequency and intensity are not increasing, and tornado activity has declined significantly since 1975.

Offer clear evidence of past, recurring major climate changes, including a widespread Little Ice Age from 1300 to 1850, a 2,400-year-old forest emerging from beneath a melting Alaskan glacier, a 5,200-year-old mummified traveler frozen on a once-nearly-ice-free Italian Alps trail – and they respond, Shut up! The climate crisis! The science is settled! Stop using fossil fuels! [bold, links added]

Fine. But take a few minutes to ponder REAL climate disasters: the Pleistocene Ice Ages.

And then ask Michael Mann, Al Gore, John Kerry, and the rest of the climate cataclysm cabal to explain exactly how carbon dioxide and a few other greenhouse gases caused those massive ice sheets to grow and melt, multiple times. Just CO2 and GHG, all by themselves. They can’t do it. The CO2-driven crisis is a fable.

Widespread glaciation began some 1,800,000 years ago in North America and Europe, and about 800,000 years earlier on other continents. There were at least four, possibly five, major glacial periods, interspersed with warm intervals (like the one we’re in now) during which the glaciers mostly melted.

That last glacial epoch is named the Wisconsinan because some of the most exemplary features are in my home state. It marks the furthest extent of glaciers southward into the United States and east and west across Canada.

LA Times reveals 2020 CA Wildfire CO2 Wiped Out 18 Years of the State’s Emissions Reductions

by L. Hamlin, Oct 22, 2022 in WUWT

The article notes that “researchers estimated that about 127 million metric tons of carbon dioxide equivalent were released by the fires, compared with about 65 million metric tons of reductions achieved in the previous 18 years.”

The Times article provided the usual climate alarmist hype that “climate change” is responsible for the California’s increased wildfire damage noting:

“Forests have long played a role in that system, with large trees sequestering carbon and helping to alleviate some emissions. But California’s new breed of climate-change-fueled fires are burning hotter and faster than those of the past, sometimes slowing the regrowth process and even converting some areas from coniferous trees into grasslands, shrubs and chaparral, the researchers said.”

However a 2021 prior WUWT article addressed the fact that year 2020 wildfire emissions likely wiped out the state AB 32 emissions reductions and also addressed in detail the huge state government forest management failures that have contributed to the states wildfire growth and increasing risks over the past decade with these critical failures hidden from view in the Times article.  This prior WUWT article notes:

“California’s climate alarmists claim “climate change” is responsible for this wildfire outcome but an extensive 2018 California Legislative Analyst Office (LAO) report presents clear and compelling evidence demonstrating that decades of forest mismanagement by the state have in fact created the growing wildfire crisis.

The LAO report notes that increased fire risks are present throughout California driven by forest conditions that have been allowed by the state to develop for decades.”

Provided below are some of the highlights (or lowlights) of the state governments forest management failures that have led directly to increased wildfire growth and risks that have nothing to do with “climate change” as addressed in the states LAO analysis and presented in the prior WUWT article.

Typhoon Frequency Has Fallen Since 1950, Contradicting Alarmist Global Warming Claims

by P. Gosselin, Oct 18, 2022 in NoTricksZone

Charts by Kirye, using data from the Japan Meteorological Agency (JMA)

Extreme weather events, like tropical storms, are supposed to be intensifying and becoming more frequent as the world warms, the global warming alarmists like to claim as they try to spread panic and anxiety. This, they say, is robustly supported by science and so humanity is facing dire consequences unless it stops burning fossil fuels immediately.

Today let’s use the scientific data on Pacific typhoons to see if the alarmist claims are true. These data are provided by the renowned Japan Meteorological Agency (JMA). Surely typhoons must be increasing in frequency year by year since the temperature has risen over the 20th century.

First we look at the number of typhoons occurring in September, since 1951:

Hurricane Hype, Lies, Censorship – And Reality

by P. Driessen, Oct 10, 2022 in ClimateChangeDispatch

Hurricane Ian is in the history books, having unleashed its Category 4 fury on southwestern Florida.

Even as the area slowly digs out and rebuilds, the devastation and tragedies will linger in reality and memories.

Ian was the latest of 123 hurricanes to hit the Sunshine State since official recordkeeping began in 1851. But unsurprisingly, some wasted no time trying to link Ian to the most dominant issue of our time. [bold, links added]

Climate change is “rapidly fueling super hurricanes,” a Washington Post headline proclaimed.

“I grew up [in Florida] and these storms are intensifying,” CNN’s Don Lemon insisted.

Rising temperatures in the atmosphere and ocean are making hurricanes “stronger, slower and wetter,” reporter Morgan McFall-Johnsen asserted.

They’re becoming more frequent and intense, multiple commentators pronounced.

Ian should have “finally ended” the debate about “whether there’s climate change,” President Biden stated, as he assessed damage along Florida’s Gulf Coast with Governor and First Lady DeSantis.

The newest fearmongering is slightly more sophisticated. Now hurricanes are gaining strength more rapidly because of fossil fuels. The phenomenon even has a fancy name: “rapid intensification.”

This clever claim cannot be proven or disproven, because we didn’t have technologies to measure how rapidly certain storms intensified even a few decades ago.
