Sahara desert dust storms carry harmful bacteria and fungi around the globe

We often dismiss springtime allergies as reactions to local pollen. Yet, something else might cause our sniffles and sneezes: a massive dust storms that originate thousands of miles away in Africa’s Sahara region.

These gargantuan dust plumes travel the globe every summer, carrying a cocktail of pollutants and potential pathogens across continents.

Dr. Shankar Chellam, a Texas A&M University professor is leading the charge to understand the biological hitchhikers within dust storms.

He and his team are working to determine what microbes, specifically bacteria and fungi, migrate with the dust and explore their potential impact on human health.

Hidden passengers in Sahara dust

“We all get allergies and potentially other more severe health effects when we breathe in dust, and it’s not fully known as to what causes those allergies,” said Dr. Chellam.

“Some people may think it is just the sand or clay minerals in the dust. Others think it is the metals or organics in the dust, and then some think it’s the bacteria and fungi.”

The Saharan dust cloud carries vast amounts of sand particles that transport bacteria and fungi.

Dr. Chellam’s research uniquely addresses how Saharan dust storms introduce these microbes into North America.

What the dust storm from Sahara tells us

Dr. Chellam and his team analyzed samples from a Saharan dust event that reached Houston in 2018. They measured metals, bacteria, and fungi to investigate any connections.

Fascinatingly, their findings revealed strong links between the biodiversity of the microbes and specific elements, especially calcium.

While these elements occur naturally in the Sahara, they also exist in our local environments. Pinpointing the exact origin of the dust and its cargo remains a challenge that scientists continue to tackle.

Our air – Not as empty as we think

Perhaps the most startling discovery is that even seemingly lifeless clouds of dust brim with biological activity.

“A key takeaway from this study is that a lot of biodiversity is not scientifically described. It doesn’t have a name, it can’t be cultured, and because it can’t be cultured, it’s difficult to study,” explained Dr. Daniel Spalink, assistant professor at Texas A&M.

The team’s high-tech DNA analysis allowed them to create an inventory of bacteria and fungi, even if the microbes themselves weren’t active.

Surprisingly, they found traces of several pathogens known to cause disease in humans, as listed by the World Health Organization (WHO).

“It doesn’t tell us if they are going to be able to infect us and make us sick,” Spalink cautions, “But at least the DNA of several pathogenic bacteria and fungi were identified in the African dust.”

Impact of climate change on Sahara dust

Climate change is altering weather patterns globally. This transformation affects dust storm behavior, leading to variations in their frequency and intensity.

In 2020, the United States experienced the most massive Saharan dust storm ever recorded, which experts named “Godzilla.”

This event highlighted the potential for increasing occurrences of such dust invasions. “The whole dynamics of the Saharan dust coming to Houston is primarily driven by atmospheric processes,” said Dr. Sourav Das, a former student of Dr. Chellam.

Global connection of Sahara dust

Sahara dust storm travels far beyond the borders of North America, affecting global environmental systems in profound ways.

This dust, originating from the vast Sahara Desert, embarks on transcontinental journeys that influence climate, ocean biology, and ecosystems far removed from its source.

The Saharan dust plays a critical role in climate regulation. As it travels across oceans and continents, it reflects sunlight back into space, cooling the Earth’s surface.

This natural phenomenon acts as a counterbalance to the warming effects of greenhouse gases, showcasing how desert dust can influence global temperatures.

However, the dust also carries microorganisms and nutrients, such as phosphorus, that fertilize remote ecosystems, from the Amazon rainforest to the Caribbean Sea, demonstrating nature’s complex nutrient cycles.

Benefits to oceans

Ocean biology benefits from the nutrient-rich dust as well. When Saharan dust settles on ocean waters, it delivers essential minerals that stimulate the growth of phytoplankton.

These microscopic plants form the foundation of the oceanic food chain, supporting a diverse array of marine life.

The influx of nutrients from the Sahara can thus boost marine productivity, affecting fish populations and the global fishing industry.

Disadvantages

The impact of Saharan dust is not universally beneficial. In ecosystems unaccustomed to the influx of foreign particles and nutrients, the dust can disrupt local environments.

For example, excessive dust deposition can smother coral reefs, blocking sunlight and hindering photosynthesis. This can stress coral ecosystems, leading to bleaching events and loss of biodiversity.

Moreover, the health implications of Saharan dust extend across continents. The dust carries not only nutrients but also pollutants and pathogens that can affect air quality and public health.

Communities in the path of these dust plumes may experience increased respiratory issues, allergies, and diseases, highlighting the need for global health monitoring and preparedness.

Study insights

It’s crucial to gather data across multiple dust events, spanning many years, to get a clearer picture of these airborne microbial communities and how they might transform over time.

While a lot remains unknown, research like this shines a spotlight on the hidden travelers swirling in the air we breathe — travelers who might be affecting our health in surprising ways.

The next time you catch a glimpse of a dust storm rolling in, remember the globe-trotting microbes it carries!

The findings of the study are published in Environmental Science & Technology.

sources and danger.

At the beginning of this year's spring season, the incidence of dust storms increased significantly.
Their frequency varies from year to year, but generally increases in the transitional periods between seasons, especially spring and autumn, for many reasons, some natural and others of a human nature, that is, by man.
Dust storms are fast winds that transport dust and plankton, causing a lack of visibility at short distances.
Despite the great controversy over the causes of dust or dust storms and the fact that the camel bears full responsibility for their occurrence, as stated in one of the videos circulated on social media, the reasons are not limited to the poor camel alone, even if it is one of the reasons!
The causes of dust storms are many, including: (1) Desertification as a result of drought resulting from low rainfall.
(2) Desertification due to human activities associated with overgrazing as a result of increasing numbers of camels and sheep on pasture capacity.
(3) Extensive agricultural activities, especially ploughing the land and leaving it exposed for long periods.
(4) Soil movement as a result of development and military actions and absurd car tracks in deserts that led to the breaking and dismantling of the soil and the destruction of vegetation cover.
(5) The reduction of the surface groundwater table, which led to the drying of the soil and thus the impact on the vegetation cover.
Globally, sub-Saharan Africa is the main contributor to Earth ’ s dust storms, which travel to the Americas via the Atlantic Ocean via tropical east winds.
But the Fertile Crescent has also become a source of dust, due to the halving of agricultural production as a result of climate change.
Iraq is one of the sources of dust storms as a result of the decline of the level of rivers, which led to the drought of the marshes and lakes in Iraq and Iran, and add to the list of sources open deserts of the Kingdom, which suffer environmental degradation as a result of human tampering of unfair grazing and wood and the like.
Dust storms are one of the factors responsible for increased allergic reactions, asthma attacks and chronic breathing problems, as well as blood vessels and heart disease.
Dust storms are also carriers of microorganisms, including bacteria, fungi, germs and viruses that cause certain diseases.
Besides, dust storms have economic effects, they adversely affect agricultural production by transporting agricultural pests, reducing photosynthetic activity, destroying crops, as well as affecting infrastructure, by reducing visibility, disrupting energy and air and road transport systems, burying railways, as well as contributing to the deterioration of the performance of solar panels, as well as damaging residential property.
There is no doubt that dust storms and their increased frequency are a warning sign that requires a rapid response through a review of environmental regulations, the need to raise the environmental awareness of the population, the organization of grazing seasons based on the identification of the pastoral capacity of each region, as well as innovative solutions to mitigate desertification that benefit from tremendous technical progress.
Finally, it follows from the above that the problem is not country-specific, but a regional problem that requires concerted efforts.
The Green Middle East initiative by Prince Mohammed bin Salman is designed to design innovative solutions to address climate change and promote environmental sustainability through a number of projects, including: planting 50 billion trees across the Middle East region and reclaiming 200 million hectares of degraded land through afforestation, which contributes to a 2.5 per cent reduction in global carbon emissions.

Many blame pollen when the allergy season begins, but there are “invisible travelers ” coming from the Sahara and Sahel region, who may be the cause of this allergy.
The huge dust plumes, which originate thousands of miles away in sub-Saharan Africa, travel by dust storms around the world every summer, carrying a mix of pollutants and potential pathogens across continents.

When desert dust settles on ocean waters, it provides essential minerals that stimulate the growth of phytoplankton that form the basis of the oceanic food chain and support a variety of marine life.
Thus, the flow of food from the Sahara could boost marine productivity, affecting fish populations and the global fishing industry.
But the effect of desert dust is not always beneficial, and in ecosystems unusual for the flow of foreign particles and nutrients, the dust can disrupt local environments.For example, excessive dust deposition can strangle corals, block sunlight and hinder photosynthesis.
Moreover, the health effects of desert dust extend across continents, where dust not only carries nutrients but also contaminants and pathogens that can affect air quality and public health.
Communities in the path of these dust plumes may face increased respiratory problems, allergies and diseases, highlighting the need for surveillance and global health preparedness.

CAMS monitors Saharan dust transport across western and central Europe

Aerosol forecasts from the Copernicus Atmosphere Monitoring Service present a big amount of Saharan mud transferring northwards throughout Europe over the following few days. CAMS continues to watch the Saharan mud transport following current forecasts that confirmed the very best values over western Europe between 15 and 17 March 2022. The CAMS forecasts additionally present degraded air high quality throughout giant components of Spain, Portugal and France associated to the Saharan mud transport.

Copernicus Atmosphere Monitoring Service (CAMS) forecasts since 11 March have been exhibiting a big plume of mud with very excessive values of aerosol optical depth (AOD) and mud concentrations travelling northwards throughout the Iberian Peninsula, France and central areas of Europe between 15 and 17 March. The trajectory of this mud plume has resulted in very excessive predicted floor concentrations of PM10 as much as 250 micrograms per cubic metre, though European Environment Agency measurements have been exhibiting values in extra of this at many websites throughout Spain on 15 March. This is larger than the EU beneficial 24-hour imply threshold of fifty micrograms per cubic centimetre.

CAMS tracks all levels of mud transport from the Sahara Desert yearly and has been monitoring the annual mud transport, from completely different supply areas throughout the desert, for the reason that starting of the 12 months. CAMS forecasts are offered at each the European and global scale, and function a instrument to assist residents, companies, and policymakers make knowledgeable selections on a steady foundation with 24/7 air high quality forecast information. Air high quality is recognised as being very important to human well being as excessive concentrations of mud can have well being impacts on the respiratory programs of all individuals within the affected areas and add to particulate matter air air pollution from native sources. Senior Scientist, Mark Parrington, on the ECMWF Copernicus Atmosphere Monitoring Service feedback: “In CAMS we use satellite and in situ observations in our air quality forecasts to be able to provide a continual and reliable source of information for monitoring air pollution events such as this. Long-range transport events such as this occur most years and the impacts of the current event is quite striking. While the dust will affect air quality in parts of southwest Europe, the larger scale impacts will be hazy skies or some surface deposition.” You can discover extra data on the CAMS monitoring of this 12 months’s Saharan mud season right here: https://atmosphere.copernicus.eu/saharan-dust-heads-north-cams-tracks-its-progress-nfAdditional air high quality information will be discovered within the Atmospheric Data Store (ADS):https://ads.atmosphere.copernicus.eu/cdsapp#!/dataset/cams-global-atmospheric-composition-forecasts?tab=overviewandhttps://ads.atmosphere.copernicus.eu/cdsapp#!/dataset/cams-europe-air-quality-forecasts?tab=overview

İZMİR

A massive dust storm from the Sahara Desert is expected to shroud the country, with experts warning citizens, especially those with respiratory disorders, to take precautions.

Professor Dr. Doğan Yaşar, a climate scientist, cautioned that a period of intense dust transport will begin on March 25.

"Red-colored desert dust laden with iron particles will arrive in large quantities," he explained.

"While this dust fertilizes the soil and benefits agriculture, it can also trigger allergy symptoms like dry cough and sneezing, especially for people with asthma or other lung conditions,” he said.

Yaşar emphasized the importance of wearing masks during this period. "People with lung diseases should wear a particle-retaining mask for three weeks, if possible," he advised. "Regular masks can offer some protection as well."

"A single pine tree produces 12 billion pollen. Thus, during this period, pollen multiplies very intensively in the air. When we inhale this, we experience discomfort. It is especially dangerous for people with lung diseases such as asthma," he added.

The dust storm is a natural phenomenon that occurs annually, transporting around two billion tons of dust from the Sahara to various parts of the world. The professor highlighted the ecological benefits of this dust, which acts as a natural fertilizer. However, he cautions that the concentrated dust can irritate airways and exacerbate allergies.

While the dust storm may cause temporary inconveniences, Yaşar reassured citizens that there's no need for alarm.

"The dust benefits agriculture, but it's important to be aware of the potential health risks, especially for those with respiratory problems," he concluded.

Layer of Saharan dust will affect the Bahamas by the weekend

By EARYEL BOWLEG

Tribune Staff Reporter

ebowleg@tribunemedia.net

RESIDENTS are urged to “safeguard their health” as a plume of Sahara dust moves over the south-east Bahamas.

The Department of Meteorology said the dust will gradually move across the country this weekend.

It warned the dust could be problematic for people with allergies and respiratory issues.

“Sahara dust is made of sand, dirt, and other dust particles that are lifted into the atmosphere from the vast Sahara Desert in Africa,” the advisory said.

Acting director of meteorology Jeffrey Simmons told The Tribune the dust tends to appear around this time every year.

He said the dust has lingered around southeastern islands for the past week, prompting some to complain about allergies.

“That’s the reason, you know, why we put out this warning alerting people about it, people who have these allergy issues or any respiratory issues so that they could, you know, be aware of the impact this could have on them for this weekend and possibly going into another week or two,” he said.

Content: Hurricane Killer? Here are some things you may not know about Saharan dust

Dust from Africa moves across the Atlantic every year from late spring to early fall

It’s a common visitor in the summer months: dust from the Saharan Desert. Hazy skies and occasional allergies are common issues caused by the dust. But did you know that this layer of dust is more interesting than it appears? Here are some things you may not know about Saharan dust:

KEY TAKEAWAYS

  • Millions of tons of dust are transported across the Atlantic every year
  • Nutrient-rich Saharan dust plays a crucial role in the global ecosystem
  • Dust suppresses hurricane development

WHOLE LOTTA DUST!

Every year, from late spring to early fall, trade winds transport 180 million tons of dust from the Saharan Desert across the Atlantic Ocean. Impressively, that’s as much as 4.5 million 18-wheelers full of dust!

NATURE’S BEST FRIEND

Saharan dust is often rich in nutrients like iron and phosphorus. As the dust settles over the ocean, it fertilizes algae and plankton, allowing them to grow and flourish in an otherwise barren environment. These organisms are vital sources of food for ocean life.

Similarly, as the dust settles over land, areas like the Amazon rainforest benefit from the extra nutrients.

HURRICANE EXTINGUISHER

The African dust that moves across the Atlantic Ocean is also called the Saharan Air Layer (SAL). The SAL occurs in waves at the same time as Atlantic hurricane season, from June through November.

It’s known that the SAL limits hurricane development and strength. This is because tropical storms like hurricanes need deep, rich moisture from the surface to the top of the atmosphere to survive. Since the air carrying Saharan dust is usually dry, it can prevent storms from forming and suppress existing storms from growing and strengthening.

DUST’S IMPACT ON TEXAS

While a dense plume of dust sometimes causes minor allergy-like symptoms for some, the most noticeable impact is on Texas skies. A haze often forms on the horizon, giving an ordinarily clear, blue sky a milky hue during the day.

At sunrise and sunset, the horizon can appear brilliantly orange because, with dust in the air, sunlight has more particles to bounce off.

Content: Saharan dust reaches stunning levels in Atlantic. Here's what that means for hurricane season

Significant Saharan dust plumes are common in the Atlantic during the start of hurricane season. If levels of SAL maintain a steadiness after about Aug. 20, then there would be significant ramifications to both the amount of cyclones and their overall strength.

First, Europe that was socked in by record levels of dust from the Sahara Desert in Africa. The Atlantic appears to have now taken the lead, with dust levels not seen in years across parts of the basin.

Satellite measurements indicate intensive plumes of dust, called the Saharan Air Layer, across much of the eastern Atlantic. Traces of dust have even made the more than 4,000-mile journey to Florida and the Gulf Coast.

Sunrises and sunsets have been enhanced across the Sunshine State as the particles scatter typical colors, allowing hues of orange, yellow and red to dominate the sky.

Aside from the vibrant colors, something not falling from the sky is precipitation.

According to NOAA, the air surrounding the SAL has about 50% less moisture than the typical atmosphere. This means the presence of the SAL can be detrimental to cloud formation and thunderstorm activity.

Significant plumes of dust and dry air are common during the first months of the hurricane season and usually persist through mid-August.

How Saharan dust impacts hurricane season

NOAA estimates that more than 180 million tons of dust leave the African continent every year, reducing thunderstorm activity and tropical cyclone formation.

Dry air and Saharan dust are perennial wild cards in tropical weather outlooks, as meteorology has yet to develop sufficient methods to forecast plumes weeks and months in advance.

Years with significant dust often experience reduced cyclone activity. Seasons with minimal dust typically rank at the top echelons of activity, thanks to increased moisture availability for tropical systems and warmer water temperatures.

The current season is a bit unusual as water temperatures started on the warm side across much of the basin, negating any minor effects from a dust storm.

Warm waters and limited exposure to dry air helped with the formations of AlbertoBeryl and Chris during late June and early July.

Since Beryl’s historic trek through the Caribbean and into the Gulf of Mexico, the basin has been relatively quiet, a likely product of the increase in dry air.

The trend for limited activity in the Atlantic basin is expected to continue for the foreseeable future, meaning that the next cyclone formation may be weeks away.

5 THINGS TO KNOW ABOUT THE SAHARAN DUST PLUME

During an average year, the fourth-named storm usually doesn’t form until about Aug. 15, meaning any formation during the next month will keep the season ahead of a typical schedule.

Despite the hostile conditions in the Atlantic, hurricane forecasters at Colorado State University maintain that 2024 will be a busy season in the Atlantic.

CSU released its updated outlook Tuesday, which calls for an additional 22 named storms, 11 hurricanes and five major hurricanes.

"This forecast is of above-normal confidence. We anticipate a well above-average probability for major hurricane landfalls along the continental United States coastline and in the Caribbean," CSU forecasters stated during their most recent tropical update. "As with all hurricane seasons, coastal residents are reminded that it only takes one hurricane making landfall to make it an active season."

The season runs through Nov. 30, but nearly 60% of cyclone formation occurs in August and September.

Research shows that dust storms coming from the Sahara Desert can severely damage solar energy production.
So, what can be done to better manage this problem?
Climate Now reports from Andalusia on efforts to beat the dust.
Announcement
On this month ’ s episode of Climate Now, we set out to southern Spain to report on the growing problem of Sahara dust, which has a significant impact on solar power generation.
Our visit to southern Spain comes as the Copernicus Climate Change Authority announced that we have seen the highest ever recorded temperature for May 2024, registering a temperature rise of 0.65 ° C above the 1991-2020 average.
This is the 12th consecutive month with the highest recorded temperature for the month in question.
In May 2024, we witnessed extreme weather conditions in many areas.
Floods in Brazil have displaced more than half a million people, temperatures in the Delhi region of India hit 49.9 degrees Celsius, its highest recorded to date, and Finland issued a heatwave warning of temperatures rising to more than 27 degrees Celsius.
In Europe, heavy rains led to flooding in southwestern Germany, Belgium, and northern Italy.
Massive losses in solar power generation due to Sahara dust
The dust of the Sahara Desert in Europe is famous for turning its skies orange, which reduces air quality and leaves a fine layer of dust on the roofs of homes and cars.
On the other hand, it causes another growing problem known as “dirty ” solar cells.
At Gianni University in Andalusia, we met with Dr. Eduardo Fernández and Professor Florencia Almonacid, who were among the authors of a recent paper that found that the severe dirt on the panels in March 2022 reduced solar capacity by up to 80 percent.
Dr Fernandez told Euronews: “It felt like we were on Mars where everything turned red. ”
March 2022 saw extreme weather, but even small amounts of dust could reduce the amount of sunlight reaching solar cells by 15%, and with the rapid growth of solar energy in Europe, losses from dirt could account for billions of euros a year.
Therefore, the research team at Jian University is using photovoltaic laboratories to find solutions.
Some scientists focus on developing dust-resistant layers, while others look at how dust accumulates with different weather conditions, such as high and low temperatures, and low rainfall.
There are many variables that need to be taken into account.
For example, dust grains may be of different sizes or colors, and can affect how well solar panel installations perform.
Even design elements make a difference, such as whether a painting is frameless or has a solid lip around its tip.
Professor Almonacid says that Sahara dust is particularly problematic: "Sahara dust particles are very fine.
It ’ s especially hard to clean. ”
The Cost and Benefit Dilemma of Solar Panel Cleaning
Renewable energy company Sonnedix faces the grime challenge every day, monitoring production from each solar power generation site and carefully calculating when cleaning PV panels is commercially feasible.
The cost of cleaning is considerable – around €400-500 per megawatt – so there are difficult choices to make depending on how the power plant is priced.
Joanne Fernandez, chief operating officer of the company, told Euronews: “As you generate electricity, every kilowatt-hour is important for the plant ’ s revenue, so this dust weather has a big impact. ”
He is now working with meteorologists to help plan cleaning sessions according to dirt weather conditions, and the amount of rainfall, as light spray may increase the soiling of the panels, and heavy rain may wash them away for free.
“Severe dust storms coming from the Sahara desert could actually lead to a significant reduction in production within the network, and this could cause a significant problem for the network operator, ” he explains.
“So forecasting, forecasting, and the ability to proactively manage the network is the most important, ” he says.
Announcement
Have dust storms from the Sahara increased due to climate change?
The recent increase in dust storms coming from the Sahara desert could be the result of natural climate variability, or it could be caused by something else.
A spokesman for the Copernicus Meteorological Authority told Euronews: “Although the arrival of dust plumes from the Sahara to Europe is not unusual, there has been an increase in the intensity and frequency of such weather conditions in recent years, and may be attributed to changes in atmospheric circulation patterns. ”
There is some speculation that these changes in atmospheric air circulation patterns are linked to climate change.
Dust expert Dr. Eduardo Fernandez says: “Scientists are always cautious about drawing conclusions, and that should be the case, right? ”
“But what we ’ re seeing is that there ’ s been a dramatic increase in extreme weather conditions, not just in terms of slabs getting dirty, but also in terms of rainfall and wind blowing.
“We are recording more dust storms coming from the Sahara, and they are increasingly penetrating into larger areas in northern Europe, and there is, of course, suspicion that global warming is the cause, ” he concludes.

Part of Europe was covered by an extremely rare cloud of dust rising from the Sahara desert.
This is reported by Der Spiegel.
“Dust from the Sahara has already arrived and you can see yellowish clouds in the air, ” said German Meteorological Service meteorologist Christian Gerold.
Dust from the Sahara on Monday, April 1, will cover Ukraine.
This is reported by the meteorological station Borispol.
According to weather forecasters, today the dust covered the Carpathian region, but tomorrow such a situation will be throughout Ukraine.
Air quality is expected to deteriorate.
The sky will also be very dark.
At the same time, the country will have abnormal heat up to + 25 degrees.
Between 60 and 200 million tons of mineral dust rise from the Sahara each year.
While large particles quickly fall to Earth, the smallest particles can sometimes fly thousands of kilometers.
A cloud of dust from the Sahara has affected air quality in some areas.
Swiss monitoring service airCHeck recorded a high level of pollution in the corridor stretching from the south-west to the north-east of the country.

Content: Have you noticed a thick film of dust settling on your car over the past day or so?

Or that the sunset has looked particularly orange or unusual?

Well, it turns out the culprit has travelled a long way to reach our shores.

The strange occurrences are caused by Saharan dust.

Yes, the dust we are seeing has travelled the about 4,700km from the Sahara Desert to Ireland.

According to Alan O'Reilly from Carlow Weather, it is because of the low-pressure system to the west of Spain which is steering up southerly winds from the south, over the Sahara Desert, up through France and towards Ireland.

"Those winds are carrying the Saharan dust so you have hot air and Saharan dust travelling from the Saharan Desert up towards Ireland," he said.

Mr O'Reilly said that we can expect the desert dust to hang around until at least the end of the week but the concentration will change from lighter to heavier at times.

"Satellite images do show quite clearly, you can see the Saharan dust in the atmosphere and quite a long trail of it back towards Spain and down to the Sahara. So it will be here for most of the week."

Generally, the dust stays up in the atmosphere above us and goes largely unnoticed by most people but when you get showers, the dust falls down with the rain.

Many people in Cork and Kerry have noticed the dust on their cars and outdoor furniture after some rain showers and have taken to social media to share photos of the desert dust.

Those who are looking to clean their newly dusted cars should use water to wash it away as wiping the dry dust could scratch the car or window.

People suffering from COPD or other breathing difficulties should monitor the levels of dust in the air and those with severe difficulties should try to stay indoors when levels are high.

"In general, most people it doesn't impact but obviously, those who already have breathing difficulties, it can cause them some more issues," said Mr O'Reilly who has already been contacted by some people concerned about the air quality.

The Saharan dust isn't all nuisance and bother though, as it lingers in the atmosphere above us, it has created some stunning sunrises and sunsets.

"If you look out for the sunset and sunrise the next couple of mornings, you might notice some more unusual colours and brighter colours," said Mr O'Reilly.

"You will get a kind of red-orange tint to the sky so that's one to look out for."

Some may be surprised to find that the arrival of Saharan dust in Ireland is not unusual.

In fact, it happens every year — sometimes more than once.

In this particular instance, there is a high concentration of dust and it is with us for a longer duration so that is why more people are noticing its presence.

Mr O'Reilly said that the desert dust arriving in Ireland just weeks after smoke from the recent Canadian wildfires was found over Ireland is a reminder of just how small the world is.

Heat relief heading for NY — other parts of US aren’t as lucky

After soaring temperatures baked the Big Apple this week, New Yorkers will see some relief in the coming days while other parts of the country won’t be so lucky.

“After a couple of toasty days up here in the Northeast that I am glad are behind us, we’re back to about average,” Fox Weather meteorologist Christopher Tate told The Post Saturday.

The thermometer was in the mid-80s Saturday afternoon, though high humidity helped the “real feel” temp reach as high as 99 degrees in some parts of the city.

Temps should stay in the 80s for the next few days, flirting with 90 degrees later in the week in the five boroughs, Tate said.

But summer thunderstorms will provide some relief.

Central Park should see a couple of heavy thunderstorms overnight and on Sunday. A flash flood alert is in effect for the Northeast due to rainfall forecast from Sunday through Tuesday.

Around New York City, the greatest risk of flooding will be from Sunday evening to early Monday, according to AccuWeather.

“I wouldn’t be surprised if we see an occasional report here or there of some standing water causing some issues or maybe some drains getting backed up but it shouldn’t be anything major,” said Tate.

Monday should be clearer, but Tate couldn’t promise there won’t be some thunder.

The southeastern United States, which experienced a blistering heat wave this week, will also get some relief, but at the expense of severe storm threats and a cold front rolling through.

The deadly heat throughout the Desert Southwest, however, will drag on, with 110-plus degree heat stretching past two weeks.

“They’re setting up for what could be one of the longest stretches of 110-degree or higher high temperatures, potentially even on record,” said Tate. “That would get them into territory where they would rival past heat waves, even by Southwest standards.”

Hot air is less dense than cold air, Tate explained, which could impact air travel in the area because it is harder to lift planes.

“Southwestern airports, notably including Phoenix Sky Harbor International Airport may have difficulties getting especially large aircraft off the ground,” he said.

And while it might feel like the Sahara in parts of the country, Florida is actually getting a piece of the African desert. A layer of Saharan dust is settling on the state, caused by strong winds that carry small sand particles from the Saharan Desert far across the Atlantic Ocean, the Miami Herald reported.

While it can make for colorful sunsets, it can be harmful to people with asthma and other respiratory issues.
