Researchers have found tiny particles of plastic in clouds, where they may be contributing to climate change.

Scientists collected water from the clouds surrounding Japan's Mount Fuji and Mount Oyama at altitudes between 1,300-3,776m and then applied advanced imaging techniques to determine whether microplastics were present, reported Sky News.

Nine different types of polymers and one type of rubber were found in the airborne microplastics, at concentrations between 6.7-13.9 pieces per liter and sizes ranging between 7.1-94.6 micrometers.

They also found an abundance of hydrophilic (or water-loving) polymers, which they said might act as "cloud condensation nuclei" - suggesting they play a key role in rapid cloud formation, which might eventually affect the overall climate.

"Overall, our findings suggest that high-altitude microplastics could influence cloud formation and, in turn, might modify the climate," the scientists wrote in the study, published in the journal Environmental Chemical Letters.

"To the best of our knowledge, this study is the first to detect airborne microplastics in cloud water in both the free troposphere and atmospheric boundary layer."

The lead author of the research, Hiroshi Okochi of Waseda University, said: "Microplastics in the free troposphere are transported and contribute to global pollution. If the issue of 'plastic air pollution' is not addressed proactively, climate change and ecological risks may become a reality, causing irreversible and serious environmental damage in the future."

Airborne microplastics degrade much faster in the upper atmosphere due to strong ultraviolet radiation, Okochi added, which "releases greenhouse gases and contributes to global warming."

The researchers said this is the first report on airborne microplastics in cloud water.

In a statement about the study, Waseda University said research shows "microplastics are ingested or inhaled by humans and animals alike and have been detected in multiple organs such as lung, heart, blood, placenta, and feces".

"10 million tons of these plastic bits end up in the ocean, released with the ocean spray, and find their way into the atmosphere. This implies that microplastics may have become an essential component of clouds, contaminating nearly everything we eat and drink via plastic rainfall," it said.

India faces challenging heatwaves each year, but few places endure conditions as searing as the country's western desert salt pans, where workers rely on simple techniques to survive almost unbearable temperatures.

Up to 50,000 workers in Gujarat spend eight months on the remote salt pans without electricity or healthcare, relying on a tanker to deliver drinking and washing water every 25 days.

They use shaded rest breaks, cloth-cooled water bottles and staggered hours to survive.

In Gujarat's Little Rann of Kutch summer temperatures routinely cross 45C, and can climb to 47-48C.

The same dry heat that makes life punishing also makes the desert ideal for salt production -- Gujarat produces roughly three-quarters of India's total salt output.

"We work in staggered timing... doing our work in early mornings and after sunset," said 42-year-old Babulal Narayan, who rakes the salt as brine water dries in shallow pools.

During the hottest hours, many retreat to makeshift huts -- frames of sticks draped with coarse homespun cloth, plastered with wild donkey dung.

"We sit here every two to three hours, so that we do not feel weak or dizzy," said 17-year-old salt worker Bhavna Rathore.

The dung blocks the sun and allows heat to escape, while the rough cloth allows some air to pass through, she explained.

The huts offer shelter in a landscape without trees or natural shade, and where the sun reflects harshly off the white salt crust.

- 'Heatwave' -

Kanchan Narayan, 44, uses a damp cloth-wrapped bottle hung on a string, cooling the drinking water inside via evaporation.

"The wind helps to cool the water," she said.

Poornima, a salt pan worker, sips black tea during the day -- saying the hot drink induces sweating in the dry weather to cool the body.

The salt is produced by pumping saline water from bore-wells into shallow pans, where the liquid evaporates under the sun and wind.

Workers rake the surface daily to ensure even crystallization. Over weeks, a thick crust of salt forms, which the workers break and stack into mounds.

The job has always involved enduring harsh conditions, but this year the India Meteorological Department (IMD) forecasts an "above-normal number of heatwave days" across several regions, including Gujarat.

Workers are exposed to the heat for longer than before.

Previously, they relied on expensive diesel pumps to bring the saline water to the surface. But a switch to solar has brought down costs and allowed families to operate the pans for longer.

That means work that used to end in March now continues into the hottest months.

- 'Fever' -

The consequences for workers can be deadly, with regular reports of fatigue, dizziness and nausea -- signs of heat stress, when the body's natural cooling systems are overwhelmed.

This can cause organ failure and even death.

Several studies have found high levels of dehydration, heat stress and even signs of kidney malfunction among these communities.

"I take a paracetamol whenever fever becomes high," said Kanchan, a rare worker wearing rubber boots -- to protect against prolonged exposure to brine, that can crack skin so deep it bleeds.

India has no fixed legal temperature at which work must stop.

Instead, it relies on IMD heatwave thresholds -- around 40C for alerts and 47C for "severe" conditions -- with local authorities imposing restrictions.

The desert conditions make the extreme heat marginally more survivable -- at low humidity, sweat evaporates more quickly off the skin, cooling the body.

But conditions are growing harder, with heatwaves intensifying and unseasonal storms also threatening livelihoods.

A sudden rainstorm can dissolve crystallized salt overnight -- forcing workers to restart the evaporation cycle.

"A big dust storm hit us last month, destroying salt worth 200,000 rupees ($2,100)," Narayan said.

He and five relatives made a profit of 250,000 rupees ($2,635) -- or $450 each for eight months of hard work.

But families say they have little alternative.

"What else will we do?" said 65-year-old worker Rasoda Rathore.

"We have no land to farm, no livestock to earn our livelihood from... this is all we know."

Egypt has reaffirmed the importance of protecting migratory birds as the country marked World Migratory Bird Day, holding activities under the slogan “Every bird counts... your observation matters” to raise environmental awareness.

Minister of Local Development and Environment Manal Awad said Egypt represents one of the world’s most important migration corridors due to its strategic geographic location linking Europe and Africa.

Millions of birds pass through the country annually during seasonal migration periods, she stated.

According to Awad, Egypt’s coastal areas and wetlands serve as vital resting and feeding stations for migratory birds. So, she stressed the importance of nature reserves in protecting these habitats and supporting biodiversity conservation.

She also highlighted several key sites for migratory birds, including the Zaranik, Ashtoum El-Gamil, and Burullus reserves along the Mediterranean coast, in addition to Ras Mohammed and the northern Red Sea islands.

Awad pointed to the winter migratory bird census project, implemented in cooperation with the Egyptian Environmental Affairs Agency (EEAA) and the Nature Conservation Egypt association, which provides scientific data on bird populations and species diversity.

The ministry said its conservation efforts include issuing annual hunting regulations and conducting campaigns to remove illegal bird-catching nets from protected areas.

Approximately 18 kilometers of illegal nets have been removed from the Ashtoum El-Gamil and Burullus reserves.
