Mysterious Fog in the US , Canada and UK: A dense, eerie fog with a "burning chemical-like smell" has spooked a good part of North America and parts of the United Kingdom and Canada. With social media amplifying all concerns, this phenomenon has sparked attention across all social media platforms. However, at the heart of this mysterious fog are a conjunction of natural events, social psychology, and environmental conditions that culminated in all the conspiracy theories and public health fears. Here's a closer look at the mysterious fog, its potential causes, and the societal response it has triggered.

Fog that Feeds Fear

The first reports of this "mysterious fog" came in from Florida where a resident said that they experienced respiratory symptoms, feverish warmth, and stomach cramps after contact with the fog. Similar stories started flooding social media, and within a day or two, a sinister force seemed to sweep across the United States, Canada, and parts of the UK. From Texas to Minnesota, people reported weird odors and health issues that they thought were linked to this bizarre atmospheric event.

Some witnesses were said to see "white particles" swirling through the air; theories ranged from a chemical attack or experimental weapon to drone-related chemical dispersals and references to historical military experiments, such as the infamous 1950s "Operation Sea-Spray."

Fuel to the fire were added when videos and posts, hundreds of thousands in number, began circulating on social media sites like TikTok and X (formerly Twitter) speculating on the origin of the fog. Hashtags like #ToxicFog went trending for days. Hysteria created a self-reinforcing loop in which every post spurred further scrutiny and fear.

Scientific Explanation of the Dense Mysterious Fog

1. What is Fog?

Fog is essentially a low-lying cloud formed when the air temperature cools to its dew point, causing water vapor to condense into tiny droplets or ice crystals. Several types of fog—advection fog, radiation fog, and valley fog—can form depending on conditions such as warm, moist air moving over cooler land or when temperatures plummet rapidly under clear skies.

2. Why the Chemical Smell?

Such chemical-like smell as reported during the occurrence of fog events is sometimes attributed to air pollution. It acts like a sponge, where it absorbs these pollutants, which include sulfur dioxide and nitrogen oxides, among others, that emit from industries. This mixture, therefore, leads to a stench that could be mistaken as unnatural or even toxic.

3. What are the Health Concerns?

High moisture levels from fog can significantly exacerbate symptoms related to respiration, but especially in already predisposed asthmatics and allergy patients. The connection of these symptoms with actual fever, stomach cramps, and puffy eyes is too remote. Experts assume that the irritating effects of entrapped pollutants trapped in fog tend to affect more the eyes and throat rather than the rest of the body affected by some report.

Psychological Effects of Mass Panic Caused by Social Media

Social media amplified a natural weather event into a health epidemic. It made the personal experience of individuals become a cause for fear and speculation, a domino effect.

According to psychologists, this is a concept of selective perception, wherein once people's attention is drawn to environmental anomalies, they begin to notice them. This mirrors earlier panics, such as the Seattle windshield pitting panic of 1954. Then, atomic bomb testing caused fear in many and started to have people looking at their windshields for small marks that they had not seen before. Likewise, postings on the strangeness of the fog probably increased public awareness and suspicion, with people looking to attach unrelated symptoms to the phenomenon.

The fog hysteria shares a commonality with other instances of mass panic, such as the "drone sightings" of recent years or the Cold War-era fears of biological warfare.

These events underscore how fear can cloud judgment, especially when amplified by social media and sensationalist headlines. While historical cases, such as "Operation Sea-Spray," offer concrete evidence of the existence of unethical experiments, the jump from a natural weather condition to theories of chemical attacks exemplifies a more modern trend of connecting unrelated dots, all wonderfully seeded in distrust and anxiety.

Despite the swirling rumors, meteorologists and scientists are in agreement that the mysterious fog is not as alarming as it seems. It is well known that fog traps and amplifies pollutants, especially in urban and industrial regions. Moreover, winter months are the most conducive for fog formation, so its recent prevalence is unsurprising.

On the other hand, environmentalists advise that the fog should wake everyone up to increased levels of pollution. The reported odors and health irritations could be just symptoms of far deeper systemic issues like industrial emissions and lack of control over air quality.

The authorities must be transparent in their communication to combat misinformation and allay public fears. Governments and environmental agencies must provide timely updates on weather phenomena, air quality, and health risks. Initiatives like real-time pollutant tracking and public education campaigns can help demystify natural occurrences while addressing valid environmental concerns.

The mysterious Canada fog is a compelling case study in how environmental events intersect with psychology and societal dynamics. While rooted in natural phenomena, the fog became a vessel for collective fears, amplified by modern technology and historical anxieties.

In this information era where communication occurs at an almost lightning pace, the fog becomes a metaphor that reminds everyone about scientific literacy, environmental responsibility, and an effective balance when considering public concern. Whether perceived as a marvel of nature or as a tale that serves to teach, it left a very powerful mark in people's minds.

Andhra Pradesh may soon follow Australia's steps and ban social media for teenagers under the age of 16 in the state.

Nara Lokesh, Information Technology, Electronics and Communications, Real Time Governance and Human Resources Development Minister for Andhra Pradesh, told Bloomberg at the World Economic Forum 2026 Annual Meeting in Davos, Switzerland: "As a state, we are studying Australia’s under-16 law, and yes, I believe we need to create a strong legal enactment.

"Youngsters below a certain age should not be on such platforms, as they do not fully understand the content they are exposed to. Thus, a strong legal framework may be required."

TDP national spokesperson Deepak Reddy supported Lokesh's claim and stated: "Children below a certain age are not emotionally mature enough to comprehend the negative and harmful content that is freely available online. That is why the Andhra government is studying global best practices and examining Australia's under-16 social media law."

If implemented successfully, Andhra Pradesh would be the first Indian state to issue the ban and could pave the way for other states to consider such policies. State officials are yet to clarify when the rule will be implemented and if any fines will be attached to it.

Is Any Other State Considering a Ban?

The petition was to emphasize on the awareness of the stakeholders and parental windows in the device that could control the menace of pornographic material which is easily accessible to children. The court asked Centre to order internet provider service companies to provide a 'Parental Window' to prevent children from accessing such content.

The Madurai Bench of Justices G Jayachandran and KK Ramakrishnan told the authorities of child rights to accelerate this matter. The bench also noted that children could only be prevented from consuming such content only if there is a parental control app on the device.

Judges also noted that parents have a higher responsibility in this, as children are highly vulnerable to such content.

What Did Australia Do?

To protect the mental health of children, Australia has successfully banned several social media apps including Facebook, Instagram, Snapchat, Threads, TikTok, X, YouTube, Reddit, and streaming platforms Kick and Twitch.

YouTube Kids, Google Classroom and WhatsApp are not covered under this rule as they do not fit those criteria.

While anyone under 16 will be still able to watch most of the content without logging in, however, they cannot have an account on it. Critics are urging the government to widen the ban to include online gaming platforms such as Roblox and Discord, which are currently not covered.

The government says that it will also reduce the negative impact of social media's "design features that encourage [young people] to spend more time on screens, while also serving up content that can harm their health and wellbeing".

A government study which was commissioned in 2025 found that 96% of children aged 10 to 15 used social media, and that seven out of 10 of them were exposed to harmful content. These content were misogynistic and violent in its nature, furthermore, content promoted eating disorders and suicide.

Children and parents will not be punished for infringing the ban, instead, social media companies will face fines of up to A$49.5m, which is equivalent of US$32m for serious or repeated breaches.

The Directorate of Public Health and Preventive Medicine (DPH) has issued a statewide alert across Tamil Nadu due to a sudden uptick in chikungunya cases in multiple cities.

Cases have been reported across Chennai, Villupuram, Tenkasi, Theni, Cuddalore, Chengalpattu, Kancheepuram and Ariyalur. It remains unknown how many people have been affected and if any deaths have occurred.

Caused by the chikungunya virus, chikungunya virus disease (CHIKVD) is spread by the bite of infected mosquitoes (Aedes aegypti and Aedes albopictus) to humans. The illness usually starts with flu-like symptoms including fever, chills, headache, nausea, vomiting, joint pain and rashes.

Typically, the illness has no clear no symptoms, especially in children and can easily be misdiagnosed as dengue and Zika. While there are no specific antiviral treatments for chikungunya virus infections, medications such as antipyretic and analgesic medications (such as paracetamol) for fever and pain can be used to ease the pain.

Most patients recover completely from the infection, but occasional cases of eye, heart, and neurological complications have been previously been reported with CHIKV infections.

What Are Tamil Nadu Officials Doing To Contain Cases?

Authorities have also emphasized that all government and private hospitals as well as diagnostic laboratories, need to timely report cases to ensure the infection does not spread . Any delay in reporting, officials noted, could allow the virus to spread rapidly within communities.

On the local level, district entomologists and health inspectors have been told to eliminate stagnant water in artificial containers and conduct weekly mass-cleaning drives in high-risk areas.

The DPH has also ordered that all designated dengue and chikungunya wards in hospitals be kept mosquito-free, with adequate bed strength and sufficient mosquito nets for patients.

Cases typically emerge mostly in the Americas, Asia and Africa and occasionally in Europe. However, nearly 30,000 CHIKVD cases have been recorded, including 83 associated deaths from 12 countries namely from China, Singapore, Pakistan, France, Argentina, Brazil and Mexico, marking it as one of the biggest outbreaks in the world.

French President Emmanuel Macron on Tuesday addressed the World Economic Forum in Davos, Switzerland. As he spoke on the European solidarity amid US President Donald Trumps' treat to annex Greenland, something else seemed to take the attention away. Macron was seen wearing a pair of blue-tinted mirrored aviator sunglasses. The surprising part was that he wore it indoors. French media had already reported that he was seen wearing sunglasses since last week.

Trump also mocked Emmanuel Macron’s sunglasses during his speech at Davos, joking, “what the hell happened?” regarding the French president’s appearance.

Why Was Emmanuel Macron Wearing Sunglasses Indoors?

On Monday, Macron said that reflective glasses were to disguise a minor eye injury that he had sustained after having been spotted with a heavily bloodshot right eye. "Apologies for the shades, but I have to wear them for a while". He further said that it is for a "mild eye condition".

Last week, when he appeared at a military event in southern France with red eye, while addressing the troop, he said, it was "totally benign" and "completely insignificant", he also added, "Please pardon the unsightly appearance of my eye". He also joked about it, calling it "l'oiel du tigre" or the "eye of the tiger". This was a reference to rock band Survivor's song used in the 1982 boxing moving Rocky III. He said, "For those who get the reference, it is a sign of determination".

What Happened To Macron's Eyes?

As per the French media reports, Macron appeared to have a sub-conjunctival hemorrhage. This means there is a broken blood vessel in his eyes. It is harmless, painless, and does not affect the vision. It also cannot cause permanent injury to the eye, and clears within a fortnight.

Macron Wears Sunglasses Indoor: Is It Absolutely Necessary?

Medical doctor and media commentator Jimmy Mohamed told French broadcaster RTL that Macron "opted for this style for aesthetic reasons, because he is a public figure. However, sunglasses are not necessary to protect vision in this condition. Some people wear it to avoid attracting attention.

"Some people might think he's ill, so to avoid being photographed in that state, he decided to wear sunglasses. The glasses protect his image, but not really his eye," said Jimmy Mohamed.

How Have Netizen Reacted To Macron Wearing Sunglasses?

He has been called 'kéké', which is a French slang for a show off. Others also joked about him being a "cyborg" or emulating Hollywood actor Top Cruise in Top Gun, the 1986 movie that made wearing aviators a fashion statement.

What Is Sub-conjunctival hemorrhage?

Sub-conjunctival hemorrhage or SCH is a common ocular condition defined by extravasation of blood beneath the conjunctiva, producing a sharply demarcated red patch on the scleral surface. The condition is usually painless and does not impair vision. It usually resolves within 1 to 2 weeks, making it a frequent but benign cause of ocular redness.

It usually happens by a sudden pressure increase from coughing, sneezing, vomiting, or heavy lifting. This could rupture tiny eye blood vessels, or from eye trauma like rubbing or foreign bodies, and can be linked to risk factors like high blood pressure, diabetes, blood thinners, or even childbirth in newborns.
