Legal Insurrection readers may recall that in 2019. I covered a book entitled “The Polar Bear Catastrophe that Never Happened” by Dr. Susan Crockford. The University of Victoria professor analyzes the latest data and reviews the questionable values in official estimates, concluding that polar bears are thriving.
Subsequently, she was fired from her position at the university.
However, it didn’t stop what she wrote from being true.
The polar bear, the iconic image of the climate crisis, has entirely lost its eco-activist mascot status. Climate expert Bjorn Lomborg (President of the Copenhagen Consensus and Visiting Fellow at Stanford University’s Hoover Institution) recently examined the numbers in a New York Post piece and came to the same conclusion. //

In any field of endeavor where one is gathering data, like, say, temperature, it's important to first determine if your measurements will be valid. If you are measuring the temperature inside an oven used for curing ceramics, you would not place your thermocouples in the lunch room. That wouldn't make any sense.
Nor does it make sense to place temperature-monitoring stations gathering data to prove global climate change, say, within a few feet of a tarmac on which jet airliners taxi for takeoff. But the United Kingdom's Met Office seems to have done just that. At the Daily Sceptic, Environment Editor Chris Morrison has brought photos: //
Teddington Bushy Park is a junk class 4 station with internationally-recognised “uncertainties” of 2°C. Joke class 4 station might be a more apt description. How anyone can think information taken at this site is suitable for scientific work that ultimately produces a global mean temperature is a mystery.
It is a mystery, unless, of course, you contemplate the idea that it may well be deliberate. I'm generally more inclined to accept incompetence rather than malice, but there sure seems to be a pattern here.
This website was created in response to the realization that very little physical site survey data exists for the entire United States Historical Climatological Network (USHCN) and Global Historical Climatological Network (GHCN) surface station records worldwide. This realization came about from a discussion of a paper and some new information that occurred on Dr. Roger Pielke Sr. Research Group Weblog.
Mid term census report of the Surface Stations Project: Is the U.S. Surface Temperature Record Reliable? - click cover image at left to download a PDF document. Now at 80%, and with a majority sample that is spatially well distributed, a full analysis will be coming in the next few months. We will however continue to survey stations in the hope of locating more CRN1 and CRN2 stations due to their rarity.
The upcoming papers will feature statistical analysis of the nationwide USHCN network in the context of siting.

What do the climate activists really want? Do they have nothing more in mind than a noble crusade to prevent the burning sky from falling on us? Or is the global warming scare just another piece of the revolution? It’s of course the latter. We know this because they’re constantly telling us it is.
The most recent admission comes from Los Angeles Times environmental reporter Rosanna Xia, whose exhausting essay under the headline “To fix climate anxiety (and also climate change), we first have to fix individualism” was posted on Wednesday – yes, Sept. 11.
Xia dwells a great deal on “climate anxiety” caused by environmental events that have afflicted the planet since its creation but are now blamed on human progress through the combustion of fossil fuels. She worries “we’ll never go back to normal” without defining sufficiently “normal” – maybe because, in a world that has never stopped changing, there is no normal. She is angry, frustrated, helpless, and exhausted.

I've always found it humorous that those activists, Progressives, etc act like they're part of the group that will have the power. They are not. They're in the back of the line for the same guillotine they believe deniers of their causes are.

Without CO2, there is no photosynthesis.
No photosynthesis, no life.
Therefore, treating CO2 as an enemy is to declare war on life itself.
Hurricane forecasters are bewitched, bothered, and bewildered. The Atlantic hurricane season was supposed to be epic. Instead, it's turned into a real dud.
Huge storms wreaking havoc on coastlines from Aruba to Long Island were supposed to line up in the Eastern Atlantic in June and hit us one at a time until late September. The damage was going to be historic and the TV coverage was going to give climate change fanatics plenty of air time to vent that "this is just a foretaste" of what's to come.
But something puzzling occurred on the way to hurricane Armageddon: not much has happened. The Atlantic Ocean has seen five named storms: two tropical storms, two hurricanes and one major hurricane this season. //
There's a lesson to be learned from the errors in hurricane forecasting. While we know a lot about the weather and how hurricanes form, what we don't know far exceeds our stored knowledge of how complex, chaotic systems behave to create deadly storms or a bright, sunny day.
It's a lesson that will go unlearned by many who could use that knowledge to realistically predict climate change.
A new study has found that a vast majority of climate policies enacted since 1998 across 41 countries have been utterly ineffective. //
The study, published in the Journal of Science, evaluated about 1,500 climate policies implemented between 1998 and 2022 by 41 OECD countries (The Organization for Economic Co-operation and Development). The study found only 63 policies (about 4 percent) that, combined, had successfully “reduced total emissions between 0.6 and 1.8 Gt CO2.” Due to the low success rate, researchers estimate the CO2 emissions from the 41 nations they studied will exceed the Paris Climate Agreement target by 23 billion metric tons by 2030.
More importantly, the study found that two popular tools most governments’ climate policies rely on — subsidies and regulations — rarely reduce emissions. Researchers found some form of carbon tax approach was more effective at reducing emissions. //
Following the 2021 Infrastructure Investment and Jobs Act (IIJA) that pledged over $110 billion in climate and energy funding, the administration introduced its Green New Deal with a grossly misleading label, the Inflation Reduction Act (IRA), in 2022, with Vice President Kamala Harris casting the deciding vote in the Senate. The IRA purported to allocate $369 billion for climate change and energy over the next decade. However, the latest Congressional Budget Office’s projection of the IRA’s climate tax credit through year 2033 has already jumped to a staggering $428 billion, a rapid 16 percent increase than the IRA originally planned. //
The Harris-Walz campaign, as pointed out by The Wall Street Journal editorial board, has shamefully used the word “freedom” to “disguise that Democratic policies seek to restrict liberty across American society.” Voters who want to be free from the government’s wasteful spending and infringement on individual rights should not fall for the Democrat’s and Harris’ deception in the upcoming election.

Part of the Atlantic is cooling at record speed and nobody knows why
8:18 AM · Aug 23, 2024
It turns out the headline is not entirely…accurate. The temperature drop is part of a climate phenomenon known as the Atlantic Nodal Mode. The pattern is like the Pacific Ocean’s El Niño/La Niña cycles but more localized.
The natural climate pattern swings between cold and warm phases every few years. Sea surface temperatures (SST) in the eastern equatorial Atlantic have a somewhat surprising seasonal cycle. The warmest waters of the year occur in spring, while the coolest waters occur during the summer. //
Perhaps the most significant aspect of the developing Atlantic Niña is its potential impact on hurricane seasons. As hurricanes strengthen in warm waters and weaken in cool ones, this could be good news for Legal Insurrection fans along the Gulf Coast and Atlantic seaboard.
Science is all too often wielded as a weapon. Whenever anyone claims, "science says," they are betraying a very real lack of understanding as to how the scientific method works; science is not a body of people or an authority — it is a tool, a method of looking at data, drawing conclusions from that data, forming hypotheses, testing those hypotheses, and seeing if others can reproduce the results. And when new data becomes available, all of the conclusions previously drawn must be evaluated, dispassionately, against that new data. Science should not — must not — be cited in support of an agenda, as that drives people claiming to be doing science to act in contradiction to the scientific method — working backward from a conclusion, discarding inconvenient data, and so on.
All of these things are happening right now in the arena of climatology.
On his Substack, science journalist Roger Pielke Jr. has described five such cases, and they merit consideration, as they show how science is being abused in pursuit of this particular agenda. Let's look at a couple.
... //
Too many people, especially people with an agenda, are not interested in the scientific method. They aren't interested in the truth. They aren't interested in decoupling science from politics. That's how we have come to this pass, where a loud, vocal, and at some times criminal element is demanding economic ruin, the end of our modern, technological society, and the return of mankind to the 19th century, all in the name of human-caused climate change that the data just doesn't support. The problem here lies not with the people who are doing science; it lies with the Al Gores, the John Kerrys, the Greta Thunbergs, the people who wave the term "science" like a battle ensign, and the vast majority of whom, like Al Gore, like John Kerry, have the carbon footprint of a medium-sized Third World nation.
This isn't science. This is the opposite of science. And these people are willing to destroy our modern lifestyle because of this — because of the bugaboo of anthropogenic climate change. //

More recently, scientific theories have become bandwagons, on which research grant grifters jump to get money. Right now, a lot of scientific research in the U.S. is being dominated by the paradigm of human-caused climate change. Into this maelstrom, faulty data and outright falsehoods are being swept around, and overwhelming responsible scientific research which attempts to find truths about earth's ecosystems. Without a framework of adherence to truth, scientific research is crowded out by political pressure exerted by ignorant advocates. //

Sadly, science is often like this; called in to support a pre decided position. Or, an old theory hanging on in the face of new data until the men whose reputation were built on the old theory have retired; continental drift is supposed to have been adopted only father a mechanism for it was established, but the truth seems to be that it was accepted by the young blood, and became official after the old guard were no longer blocking it.
My late father was a Professor of the History of Science and Technology, so I gat a lot of this over the dinner table.
Yes, in theory, when the data contradicts theory, the theory gets junked. Seldom happens that directly, though.
Climate Change activism is a particularly squalid case. It doesn’t help their case that their proposed ‘solutions’ are mostly fairy tales. Wind, solar, and battery powered cars will not help, and may cut ally harm the environment more than what they are supposed to replace. I would, in particular, like to see somebody, ANYBODY, taking a hard look at what having wind and solar farms taking energy out of the environment does in terms of side effects. The enviroweenies act like that energy is free, and There Ain’t No Such Thing As A Free Lunch. //

There are so many “climate science” articles that are almost immediately outdated by real-world observations it’s almost funny.
Case in point: I just ran across a recent study that showed that the Great Barrier Reef had rebounded from its 2009 lows to an unprecedented level (30% higher than standard levels of coral colonies) in just 15 years. Remember how all the coral was “dying” and being “bleached” because of CO2 and ozone blah blah blah? Not so much.
Turns out those lows in 2009 (and they were pretty low then) were due to a cyclone that passed almost directly over the entire GBR a year before. Causing widespread damage to the corals (which happens from time to time).
Rest assured, the GBR is not going anywhere, and in fact seems to be sticking a big middle finger to the climatistas by rebounding to far greater numbers than were thought possible. //

Some decades back I made the observation that at least half the ‘environmental emergencies’ talked about would vanish if we executed the board of directors of The Sierra Club, Greenpeace, and the like. I think a fair proportion of the others - runaway wildfires spring to mind - could be solved by taking large tracts of land away from various governments and making them privately owned. In the developing world, too much damage is done because the companies working the land have leases from the government instead of owning, and know they have to make all the money they are going to get before tge lease runs out.
Last November, Virgin Atlantic Airways made headlines for completing the world’s first transatlantic flight using “100 percent sustainable aviation fuel.”
This week, the Advertising Standard Authority (ASA) of the U.K. banned a Virgin radio ad released prior to the flight, in which they touted their “unique flight mission.” While Virgin did use fuel that releases fewer emissions than traditional supplies, the regulatory agency deemed the company’s sustainability claim “misleading” because it failed to give a full picture of the adverse environmental and climate impacts of fuel.
A forthcoming study seeks to inform how courts consider challenges to these regulations by establishing once and for all that the lawmakers who shaped the Clean Air Act in 1970 knew scientists considered carbon dioxide an air pollutant, and that these elected officials were intent on limiting its emissions.
The research, expected to be published next week in the journal Ecology Law Quarterly, delves deep into congressional archives to uncover what it calls a “wide-ranging and largely forgotten conversation between leading scientists, high-level administrators at federal agencies, members of Congress” and senior staff under Presidents Lyndon Johnson and Richard Nixon. That conversation detailed what had become the widely accepted science showing that carbon dioxide pollution from fossil fuels was accumulating in the atmosphere and would eventually warm the global climate. //
“The argument that the Clean Air Act for some reason should not include the regulation of greenhouse gases is simply wrong,” Burger said
CO2 makes the planet greener.
Plant transpiration is vital to plant growth and terrestrial ecosystems.
The rising CO2 trend over the last 30 years (1990-2020) has been the primary driver of planetary greening, or increases in Leaf Area Index (LAI).
The greening, in turn, is predominantly responsible for the widespread increase in plant transpiration over this period.
These elevated trends in greening and plant transpiration are expected to continue unabated to 2100, accelerating with the increases in emissions.
“The trend attribution analysis results show that the change in leaf area index (LAI) can explain 66.2% of the global PT trend, indicating that elevated LAI due to global greening is the dominant factor contributing to the upward trend in global PT. The elevated LAI can be largely attributed to the CO2 fertilization effect induced by elevated atmospheric CO2 concentration.”
That's a lot of science-speak for "rising CO2 levels result in increased plant growth."
Increased plant growth means plants, which are, in effect, carbon sinks, increase their takeup of CO2 and their output of O2 — oxygen. That's good for plants, good for animals, and good for the planet — all without wrecking our economy with drastic carbon-emissions measures.
Who are we to determine what the Earth’s “correct” temperature range is? This little blue-green sphere is a tad over four and a half billion years old. Through most of that time, it’s been a lot warmer than it is now. As recently as the Eocene, maybe the Oligocene, there were no polar ice caps. In the more recent interglacials, global temps were higher than now. During the Roman occupation of Britain, there were vineyards that would not survive today’s British climate.

Somehow, the NYT and their bevy of so-called experts think they can divine the cause of these fires. In each case, the NYT has blamed climate change as either a driver or contributor to these three fires without so much as a shred of proof. In fact, the NYT contradicts their own claims in the table of the top ten fires in California by acreage burned provided in their article. //
While there was indeed a heat wave prior to the Park Fire, that had no bearing on the fire at all. The area where the fire ignited, Butte County, California, and the most-burned area in Tehama County are not in drought conditions according to the U.S. Drought Monitor for July 23 – the day before the Park Fire was ignited by a criminal arsonist.
So, “climate change caused drought” creating abnormally dry conditions didn’t figure into the Park Fire at all. The fire wouldn’t exist without the criminal act of arson.
The arson ignition point in Chico’s Bidwell Park is in the foothills of the Sierra Nevada. Just to the north of that point, huge acreages of grassland and scrubbrush exist. Combine that ignition with the sustained southerly winds that day of 20-25 mph, and it is no surprise that the fire rapidly spread north. Rick Carhart, the Public Information Officer for CalFire in Butte County and a Chico resident for decades, confirmed in a telephone interview that the area “had not naturally burned in several decades, and had no control burns to reduce fuel loads.” He added that these “high fuel loads, combined with the wind that day made a very aggressive fire.”
Climate change contributed nothing to the actual circumstances or rapid spread of the fire – local weather and a criminal act are at fault. The drying of grasses (which happens every spring) and the heat wave (which happens every summer) are both weather patterns that operate on short-term time scales as opposed to long-term climate change.
My colleague, Heartland Institute Research Fellow Linnea Lueken, published a scathing factual rebuttal last year of a case with The Sacramento Bee making similar, baseless claims like the NYT when they attempted to connect climate change to wildfires and their natural drivers, such as lightning. She writes:
The Intergovernmental Panel on Climate Change finds no climate signal, nor increasing trend, behind thunderstorms, or lightning occurrences. Also, NASA satellites have documented a global long-term decline in wildfires. NASA reports satellites have measured a 25-percent decrease in global lands burned since 2003.
Examining wildfires in California in particular, research shows massive wildfires have regularly swept through the state. Indeed, a 2007 paper in the journal Forest Ecology and Management reported that prior to European colonization in the 1800s, more than 4.4 million acres of California forest and shrub-land burned annually. As compared to the 4.4 million California acres that burned each year prior to European colonization, only 90,000 acres to 1.6 million California acres burn in a typical year now.Clearly, there is no climate change component to California wildfires at all. If there were, fires in the present would be consuming much more than 4.4 million acres annually – but this isn’t happening. The simple fact is: Arsonists are responsible for more wildfires than climate change. The intensity and coverage of wildfire varies greatly from year to year, as evidenced by the 2022 NYT story: Why California’s 2022 Wildfire Season Was Unexpectedly Quiet. A map of fires from year to year in the article demonstrates this well.
A stack of one trillion one-dollar bills would reach the Moon and back four times. Janet Yellen is proposing to spend a stack, not a fistful, of dollars that would reach to the Moon and back twelve times. That's the scale of spending she's talking about - it is, literally, astronomical. And she wants to spend this money on the nebulous idea of anthropogenic climate change.
U.S. Treasury Secretary Janet Yellen said on Saturday that the global transition to a low-carbon economy requires $3 trillion in new capital each year through 2050, far above current annual financing, but that filling the gap is the biggest economic opportunity of the 21st century.
In a new report, first shared with The Hill, analyzing public statements made by lawmakers, the think tank determined these climate deniers are all Republicans and include prominent members of House leadership.
It defined climate deniers as lawmakers who say any of the following: climate change is not real, it is not primarily caused by humans, the science is not settled on climate change, extreme weather is not caused by climate change, or climate change is actually beneficial. //
Fourth: "The science is not settled on climate change." This, again, isn't an unreasonable attitude because the science is not settled on climate change, and the science never will be settled on climate change, because that's not how the scientific method works. Science is not a philosophy, it is a tool, a method used to look at data and derive conclusions from it, to test hypotheses and develop theories that explain the data — the observations. Scientific theories are tentative, and are always open to being revised in light of new data; science is never "settled." That's not how this works; that's not how any of this works. //
While it's not necessarily an indicator of climate change or the lack thereof, it's important to note that human deaths due to severe weather have dropped by almost 99 percent in the last 100 years. //
The Center for American Progress, it must be noted, is not a scientific organization; it is a far-left activist group. This "analysis" is not an analysis at all; it is an attempt at a "gotcha," working backward from a conclusion, to try to make the point that anthropogenic climate change is something worth wrecking our economy and our modern technological lifestyle over. It also seeks to cast Republicans as the villains in the story. This isn't an analysis. It's not science, and it's not even remotely close to the scientific method; it is ideology couched in vaguely science-ish terms to make it sound plausible to the credulous.
Scientists from the Woods Hole Oceanographic Institution are seeking a federal permit to experiment in the waters off Cape Cod and see if tweaking the ocean’s chemistry could help slow climate change. //
The scientists want to disperse 6,600 gallons of sodium hydroxide — a strong base — into the ocean about 10 miles south of Martha’s Vineyard. The process, called ocean alkalinity enhancement or OAE, should temporarily increase that patch of water’s ability to absorb carbon dioxide from the air. This first phase of the project, targeted for early fall, will test chemical changes to the seawater, diffusion of the chemical and effects on the ecosystem.
If successful, the team plans to conduct a larger trial next year in the Gulf of Maine.
Just for the record, the Atlantic Ocean contains 82 billion billion gallons of water. That's a lot of water. (And yes, gallons. I use freedom measurements.) The world's oceans combined contain 97 percent of the water on the planet, amounting to 352,670,000,000,000,000,000 gallons. Even if this experiment were to yield some measurable results, what do these researchers propose to do next? There isn't enough lye on the planet to be able to do this on a global scale. //

And thank God they are not able to do it to sufficient scale to have any measurable effect. We currently have an atmosphere with roughly 420 Parts Per Million CO2. Ideal saturation for plant growth is closer to 1500 PPM, and the Earth has averaged somewhere around 1000 PPM for the entirety of its existence. At 150 PPM, plants start dying off at a potentially unrecoverable rate. In other words, we don't have too much CO2. We have too little... or at the very least on the lower end of acceptable. CO2 doesn't cause climate change. It is a byproduct of climate change. When the Earth warms, CO2 increases.... usually after a period of between 50 and 100 years (depending on how rapidly the Earth warmed). During the glacial eras, CO2 was down to about 180 PPM. These clowns, likely trying to get grant money, are going to some day do something that actually does have an effect, and endanger actually killing the planet... because when the plants go, the animals aren't far behind.

...measured temperature data clearly established that these “record” claims are completely phony and represent dishonest and climate science incompetent media driven climate alarmist political propaganda. //
A recent ClimateRealism Fact-Check June 2024 article addressed the climate science data unsupported claims by climate alarmist media that hyped phony temperature “records” (shown below) have occurred in June across the U.S. which the article establishes as being completely false.
NOAA has updated its Contiguous U.S. climate temperature anomaly and absolute temperature measurement data results through June 2024 with these results showing that the temperatures experienced this June were not “record” high outcomes as falsely portrayed by the climate alarmist media’s phony political campaign hype.
NOAA‘s June 2024 Contiguous U.S. USCRN maximum temperature anomaly data (shown below) clearly indicates that not only is there no established trend of increasing maximum temperature anomalies during the period starting in 2005 but also the June 2024 anomaly value (2.84 degrees F highlighted in red) is below the prior highest June value of 3.91 degrees F in 2021 as well as far below the highest anomaly value ever recorded during this period of 7.72 degrees F that occurred in March 2012.
NOAA’s Contiguous U.S. maximum absolute temperature measured data for the month of June for the period 1895 through June 2024 (shown below) establishes that June 2024 (84.61degrees F highlighted in red) value is only the 6th highest measured June value with the highest June value occurring in June 1933 of 85.91 degrees F
But no, 2024 isn't the warmest June in history. That honor belongs to the year of Dad's favorite hot weather stories - 1933.
If you look at the chart titled "Contiguous U.S. Maximum Temperature" for June, the nine hottest Junes on record are, in order of highest temps, 1933, 2021, 1988, 2016, 1918, 2024, 1936, 1394, and 1911 - six of the nine were in the 20th century, with five being before World War 2.
That doesn't seem to show much of a trend.
Add to this the fact (again, from a government source, and the Environmental Protection Agency to boot) that the air quality is better today than it has been in many decades, with specific pollutants dropping dramatically.
The calculator is based on the Intergovernmental Panel on Climate Change’s (IPCC’s) Model for Assessment of Greenhouse Gas Induced Climate Change (MAGICC). As the documentation illustrates, this model has myriad assumptions about climate. The Climate Calculator focuses on two key assumptions: climate sensitivity and the level of emissions reduction. Scientists generally agree that the Earth’s temperature warms as CO2 emissions increase—the real question is to which degree (no pun intended).
Climate sensitivity measures how much the Earth’s temperature will warm as a result of a doubling of atmospheric CO2 concentration. The emissions-reduction level is the percentage of CO2 emissions that lawmakers would seek to reduce with respect to current emissions. The methodology below contains full details.
The simulations presented in this calculator allow user-selected climate sensitivities between 2℃ and 5℃, stated as the “very likely” range of climate sensitivity according to the IPCC’s Sixth Assessment Report, encompassing the “likely” range of 2.5℃ to 4℃. Although empirical evidence comparing observations to predictions suggests that sensitivities at the lower end of these ranges may indeed be more plausible, Heritage’s Climate Calculator allows users to decide which climate sensitivity they would like to assume and how steep of a reduction in fossil fuel use they would like to see. The results speak for themselves—regardless of the assumptions, the climate impact of CO2–reduction policies is slim to none!
