2021 Update comes from Brendan O’Neill writing at Spiked Climate Derangement Syndrome.  Excerpts in italics with my bolds.   Let’s Go, Brendan!

It’s the hysteria about climate change that poses the greatest threat to humanity.

The first thing to note about Climate Derangement Syndrome, whether it’s coming from the posh road-blockers of Insulate Britain, Clarence House or the Church of England, is that it has nothing whatsoever to do with science. This eco-hysteria single-handedly shatters the myth that contemporary environmentalism is a science-driven movement, merely concerned with acting upon the warnings contained in graphs and models drawn up by climatologists. Show me the piece of scientific research that says a gang of boys will rape your mother if we don’t achieve Net Zero by 2030. Where’s the peer-reviewed study that pinpoints the moment when slaughter, rape and genocide will occur if our governments fail to cut back on fossil fuels?

Of course no such studies exist. These malarial visions of future horrors spring from the realm of fantasy, not science. They are the misanthropic prejudices of the depressed middle classes, not scientific projections. They emerge from the well of existential dread in which the contemporary elites wallow, not from cool, calm modelling. And the truth is that this has long been the case with climate-change alarmism. ‘Science’ is the garb thrown on what in reality is the End Times foreboding of this new millennium’s morally at-sea elites. ‘Climate change’ is the all-encompassing idea of doom through which the Western bourgeoisie expresses its sense of moral, political and economic exhaustion.

All the recent talk of doomsday and genocide captures the extent to which the issue of climate change has been catastrophised to an extraordinary degree, how it has been transformed:

• from a perfectly manageable problem into an apocalypse modernity brought upon itself;
• from a scientific theory about mankind’s impact on the planet into certain, unquestionable proof of the folly of the industrial era;
• from one challenge among many facing humankind in the 21st century into an indictment of the entire human species.
• In short, from a technical conundrum into a God-like revelation of the wickedness of greedy, industrious mankind.

Climate Derangement Syndrome is at root a revolt against modernity. It is a reactionary, Romantic, nostalgic cry of angst against the incredible world of production and consumption mankind has created over the past 200 years. This is why some at COP26 openly denounced the Industrial Revolution. First came Greta Thunberg, the prophetess of doom of contemporary environmentalism. She angrily denounced the British government as ‘climate villains’. The UK, she said, is largely responsible for the horrors of climate change – this ‘more or less… started in the UK since that’s where the Industrial Revolution started, [where] we started to burn coal’.

It was the Industrial Revolution that dragged the populace away from the brutal, back-breaking serfdom of the land into the mad, teeming cities of London, Manchester, Sheffield, Glasgow. It revolutionised how we worked, how we lived, how we conceived of ourselves. It was the cradle of solidarity and struggle and demands for voting rights, employment rights, educational rights. It is not a coincidence that life expectancy was depressingly short for all of human history until the Industrial Revolution, when it started its stunning and steady rise. Without this revolution, most of us would still be tied to the land, never venturing further than the farm fence, unable to read, dead by 35. That’s the idyll eco-regressives fantasise about? These people are as historically illiterate as they are pseudo-scientific.

The COP26 mockery of the Industrial Revolution – more than that, the depiction of that revolution as the starting pistol of the coming climatic genocide – shines a harsh light on what is motoring today’s green hysteria. Not steam or coal, that’s for sure.

No, it’s the elites’ loss of faith in modernity and in the human project more broadly. This is why climate-change hysteria is a far larger problem for humankind than climate change itself.

As Bjorn Lomborg recently explained on spiked, climate change is a ‘middling problem’. It is the derangement over climate change, the painting of it as an End Times event we probably deserve, that truly disrupts and undermines our civilisation. With its misanthropic disdain for human behaviour and aspirations, with its revisionist treatment of the birth of modernity as essentially a crime against Mother Earth, with its incessant demands for reining in economic growth, and with its censorious branding of anyone who questions any part of the regressive green agenda as a ‘climate-change denier’, climate-change alarmism is an express menace to growth, democracy, freedom of speech and the right to dream of an even more prosperous future for all.

Prince Charles is right that we need to get on a ‘war footing’. Not against climate change, though. Rather, against this ceaseless diminishment of humanity’s achievements and the baleful, untrue claim that modern man is a plague on the planet. This manmade apocalypticism threatens to upend the remarkable civilisation we have created far more than a bit of carbon does.

Background on Climate Delusional Disorder

WebMD tells What You Need to Know about this condition.  Delusions and Delusional Disorder. Excerpts in italics with my bolds.

Delusions are the main symptom of delusional disorder. They’re unshakable beliefs in something that isn’t true or based on reality. But that doesn’t mean they’re completely unrealistic. Delusional disorder involves delusions that aren’t bizarre, having to do with situations that could happen in real life, like being followed, poisoned, deceived, conspired against, or loved from a distance. These delusions usually involve mistaken perceptions or experiences. But in reality, the situations are either not true at all or highly exaggerated.

People with delusional disorder often can continue to socialize and function normally, apart from the subject of their delusion, and generally do not behave in an obviously odd or bizarre manner. This is unlike people with other psychotic disorders, who also might have delusions as a symptom of their disorder. But in some cases, people with delusional disorder might become so preoccupied with their delusions that their lives are disrupted.

What Are the Complications of Delusional Disorder?

• People with delusional disorder might become depressed, often as the result of difficulties associated with the delusions.
• Acting on the delusions also can lead to violence or legal problems. For example, a person with an erotomanic delusion who stalks or harasses the object of the delusion could be arrested.
• Also, people with this disorder can become alienated from others, especially if their delusions interfere with or damage their relationships.

Treatment most often includes medication and psychotherapy (a type of counseling). Delusional disorder can be very difficult to treat, in part because those who have it often have poor insight and do not know there’s a psychiatric problem. Studies show that close to half of patients treated with antipsychotic medications show at least partial improvement.

Delusional disorder is typically a chronic (ongoing) condition, but when properly treated, many people can find relief from their symptoms. Some recover completely, while others have bouts of delusional beliefs with periods of remission (lack of symptoms).

Unfortunately, many people with this disorder don’t seek help. It’s often hard for people with a mental disorder to know they aren’t well. Or they may credit their symptoms to other things, like the environment. They also might be too embarrassed or afraid to seek treatment. Without treatment, delusional disorder can be a lifelong illness.

H.Sterling Burnett and James Taylor write at Epoch Times United Nations Misleads About Food Production and Climate Change. Excerpts in italics with my bolds

There is no better way to describe the arguments contained in the U.N. Intergovernmental Panel on Climate Change’s (IPCC) new report, “Climate Change and Land,” released just in time to influence discussions at the United Nations’ 68th Civil Society Conference. Citing anecdotal evidence instead of hard data, IPCC’s new report paints a dark, disturbing picture about the current and future state of crop production and food availability.

“Climate change, including increases in frequency and intensity of extremes, has adversely impacted food security and terrestrial ecosystems as well as contributed to desertification and land degradation in many regions,” the report claims.

“Warming compounded by drying has caused yield declines in parts of Southern Europe. Based on indigenous and local knowledge, climate change is affecting food security in drylands, particularly those in Africa, and high mountain regions of Asia and South America,” the report continues.

Here, climate alarmists in the United Nations are doing nothing more than “pounding the table,” hoping fear will drive the public to demand “climate action now!”

Of course, the fake news media eagerly amplified the alarmist report. For example, an Aug. 8 NBC News headline reads, “Climate change could trigger a global food crisis, new U.N. report says.” Many other major media outlets published similar stories.

The biggest problem is the report’s thesis and “facts” are totally wrong—and that’s quite a problem!

For instance, the United Nations’ own data shows farmers throughout the world are setting new production records virtually every year. In fact, the U.N. Food and Agriculture Organization reports new records were set in each of the past five years for global cereal production, which is composed of the Big Three food staples: corn, wheat, and rice.

Indeed, World-Grain.com reports in 2016 world cereal production broke records for the third straight year, exceeding the previous record yield, recorded in 2015, by 1.2 percent and topping the record yield in 2014 by 1.5 percent. These facts should not surprise anyone because hundreds of studies and experiments conclusively demonstrate plants do better under conditions of higher carbon dioxide and modestly warmer temperatures.

The ongoing record crop production perfectly illustrates the difference between the Climate Delusion perpetrated by IPCC and other government-funded alarmists and what is actually happening in the real world. To make the news gloomy, IPCC’s report nefariously engages in semantic tricks to give readers a false impression of declining global crop production. The report cites anecdotal evidence crop yields are declining in “parts” of Southern Europe, ignoring copious data showing crop yields are rising across the globe, including throughout Southern Europe.

Instead of highlighting this welcome development, IPCC focuses on what it claims are yield reductions in some small regions of Southern Europe. Readers who are not paying close attention will be led to believe, incorrectly, that crop yields are declining throughout Southern Europe. In reality, the exact opposite is true!

IPCC claims “indigenous and local knowledge” indicates food production is declining “in drylands” in Africa, Asia, and South America. However, such indigenous and local knowledge does not trump objective data, which are readily available to IPCC’s authors and show crop yields are increasing throughout Africa, Asia, and South America as a whole, including in dryland areas.

Tragically, IPCC’s misleading claims result in people who dare to point out crop production continues to set new records being accused of “denying” climate change and attacking science. Climate change is real and record crop production is in fact consistent with it. In fact, record crop production is partly due to climate change.

This is just the latest example of the ongoing Climate Delusion, as radical environmental activists, government bureaucrats, socialists, and a biased news media, looking to transform U.S. society, repeatedly make ridiculous climate claims with no basis in real environmental conditions. They hope the constant drumbeat of authoritative-sounding claims will fool people into stampeding politicians to give governments more power over the economy to combat the false climate crisis.

Fortunately, we can avoid this fate. Factual data showing the truth about global food supplies and other climate conditions are readily available to anyone willing to search the internet. Let’s hope the public accesses the facts. Enacting policies that restrict the use of abundant energy supplies will rob people of choice and harm the economy. This won’t hurt the global elite, but it will result in everyone else living poorer, more precarious lives.
