Saharan dust storms can have significant impacts on weather and air conditions in the Americas, including reducing sunlight and visibility, and increasing small pollution particles, which can have adverse effects on human health, particularly for individuals with respiratory illnesses, and can cause respiratory risk warnings to be issued by authorities.

The dust storms can also have economic impacts on cities like San Antonio, TX, by reducing visibility, disrupting transport systems, and potentially affecting traffic infrastructure, as well as damaging air quality and contributing to dark skies globally.

In San Antonio, TX, Saharan dust is expected to arrive in late June through mid-August, bringing hazy skies and breathing troubles, and affecting air quality levels, with people with asthma and COPD being particularly affected by the dust.

The dust can also cause minor allergy-like symptoms in Texas, and can give the sky a milky hue during the day, and make the horizon appear orange at sunrise and sunset, with the Saharan Air Layer limiting hurricane formation and growth from June to November.

Saharan dust storms can carry harmful bacteria and fungi globally, including into North America, which can impact human health and introduce microbes into the environment, and can disrupt local environments, affect public health, and carry pollutants and pathogens across continents.

City planners in San Antonio, TX, can utilize advanced weather forecasting and modeling to predict the immediate weather effects of an incoming Saharan dust storm, and can prepare for the potential impacts of Saharan dust storms by reducing outdoor activities, keeping windows and doors closed, and issuing warnings for individuals with respiratory illnesses.

Appropriate preparations can also include monitoring air quality levels, providing guidance on how to reduce exposure to dust, and taking steps to mitigate the effects of dust on local environments and public health, such as increasing green spaces, which can help face dust storm challenges and mitigate dust storm effects.

Green infrastructure, such as urban parks and green roofs, can play a crucial role in mitigating the effects of Saharan dust storms on urban air quality and temperature, by reducing air pollution, improving air quality, and increasing cooling through evapotranspiration.

The city's power grid and traffic infrastructure can be prepared to withstand the potential impacts of a Saharan dust storm by implementing measures such as regular maintenance, backup power systems, and traffic management plans, and by coordinating with authorities, intensifying traffic services, and making preparations to face wind speed repercussions.

Dust storms can also have positive impacts, such as suppressing hurricane development and strength, and fertilizing remote ecosystems with nutrients, but the negative impacts of these storms, including the potential for respiratory problems and allergies, and the disruption of local environments, must be carefully considered and prepared for by city planners.

Overall, understanding the impacts of Saharan dust storms on weather and air conditions in the Americas is crucial for developing effective preparations and mitigation strategies, and city planners in San Antonio, TX, should take a proactive approach to preparing for and responding to these events.

The economic impacts of Saharan dust storms on San Antonio, TX, can include increased healthcare costs, lost productivity, and damage to infrastructure and property, and businesses and industries in San Antonio, TX, can prepare to respond to Saharan dust storms by implementing measures to reduce dust exposure, such as improving air filtration systems and providing protective equipment for employees.

Communities in San Antonio, TX, may experience increased respiratory issues and diseases due to Saharan dust storms, which can lead to economic impacts on the healthcare system, and the city can prepare for Saharan dust storms by monitoring air quality, providing public health alerts, and implementing measures to reduce dust exposure.

Saharan dust storms can also impact the city's power grid, with dust storms reducing solar energy production by up to 80 percent, and small amounts of dust reducing sunlight reaching solar cells by 15 percent, which can have significant economic impacts on the city's energy sector.

Forecasting and proactive management can mitigate dust storm impacts on the power grid, and city planners in San Antonio, TX, should consider the potential economic impacts of Saharan dust storms on the city's infrastructure and businesses, and develop strategies to address these impacts.

Early warning systems can mitigate dust storm effects, and city planners in San Antonio, TX, should utilize advanced weather forecasting and modeling to predict the immediate weather effects of an incoming Saharan dust storm, and prepare for the potential impacts of Saharan dust storms.

Content: Recently, Athens and other parts of Greece were hit by a sandstorm from the Sahara desert, the sky was orange and seemed to be in a different world, as many people watched the spectacle outside, while authorities issued a respiratory risk warning.
According to foreign news reports such as the Guardian and CNN, Greece was hit by a sandstorm in the Sahara Desert between the end of March and the beginning of April this year, affecting even Switzerland and southern France.
Unexpectedly, the Sahara dust storm hit Greece again on the 23rd, and the National Observatory of Athens said: “This is the most severe dust concentration in the Sahara since March 21-22, 2018. ”
Authorities have warned that sand and dust can block sunlight and obstruct visibility, while the concentration of small pollution particles in the air can increase, which may have adverse effects on the human body.
From the picture, the Athens sky is darkened by dust from the Sahara, and the city seems to be covered in a dark orange curtain, but this does not frighten the locals, who are instead strolling outside to enjoy the strange scenery.
Greek meteorologist Kostas Lagouvardos said in a Facebook post that Athens looked like a “colony of Mars. ”
In fact, 60 to 200 million tonnes (60 to 200 m tonnes) of dust is raised in the Sahara every year. While the largest particles fall back to the surface quickly, the smallest particles can travel thousands of kilometres and may even spread across Europe.

The dust storms can also have economic impacts on cities like San Antonio, TX, by reducing visibility, disrupting transport systems, and potentially affecting traffic infrastructure, as well as damaging air quality and contributing to dark skies globally.

Title:

Content: The amount of dust in the world's air worsened in 2022, according to the United Nations World Meteorological Organization.
The organization called for more research on the relationship between climate change and increasing sandstorm hotspots.
The rise in dust is attributed to increased emissions from areas such as West Central Africa, the Arabian Peninsula, the Iranian Plateau, and northwest China.
WMO President Petteri Taalas stressed that human activities affect sandstorms and dust storms.
Higher temperatures, drought and increased evaporation lead to lower soil moisture, which, together with poor land management, contributes to more frequent sand and dust storms.
The annual WMO report analyses the occurrence and risks of dust storms and highlights their impact on society.
The report revealed that the global average annual dust surface concentrations in 2022 were slightly higher than in 2021.
In 2021, the figure was 13.5 micrograms per cubic meter, while in 2022 it rose to 13.8 micrograms per cubic meter.
The Baudeli region of Chad recorded the highest estimated annual average surface dust concentration, ranging from 900 to 1,200 micrograms per cubic meter.
In the southern hemisphere, central Australia and the west coast of South Africa recorded the highest concentrations, ranging from 200 to 300 micrograms per cubic metre.
Dust storms have far-reaching effects, contributing to the dark sky and damaging air quality.
Nearly 2,000 million tons of dust enter the atmosphere each year, affecting economies, ecosystems, weather and climate, even in areas thousands of kilometers away, the report said.
While natural processes play a role, poor water and land management also contributes significantly.
The bulletin highlighted three major incidents in 2022, including an “exceptional dust outbreak ” from North Africa over Spain and Portugal, which exceeded EU air quality regulations.
Another severe dust storm occurred in the Middle East, resulting in reduced visibility across the region.
In addition, a dust storm on farmland in the eastern United States affected agricultural activities.
Taalas stressed the importance of addressing the effects of sand and dust storms on health, transport and agriculture.
The publication called for more research on the relationship between dust storms and climate change, as this region remains largely unexplored.
The World Meteorological Organization aims to establish early warning systems for weather disasters around the world within four years to mitigate the worsening effects of climate change, including dust storms.

San Antonians may want to stay indoors next week. Here's why.

A noticeable change in the air will arrive to the Alamo City next week.

SAN ANTONIO — San Antonio skies could look quite different next week but not in the way we're hoping for.

As San Antonians eagerly wait for rain to break our triple-digit temperatures another common occurrence will pick-up next week known as Saharan dust.

The dust is a combination of sand and dust traveling from North Africa across the Atlantic that peaking in late June through mid-August.

Light amounts of Saharan dust have arrived to the Alamo City this past week but will become more noticeable. Therefore, if you have asthma, COPD or any other type of respiratory illness you will want to stay indoors as much as possible during this time.

Timing of Saharan dust:

Monday - Little changes will be in the forecast as heavier amounts of dust remain over the gulf coast.

Thursday - As the week progresses dust levels continue to rise and could affect air quality levels. For those with any respiratory illnesses they should avoid outdoor activity including vigorous exercise. Also try to keep windows and doors closed. We will continue to monitor this development next week.

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.

What areas of the US have been affected by Saharan dust storms?

Saharan dust storms can carry harmful bacteria and fungi globally, including into North America, which can impact human health and introduce microbes into the environment, and can disrupt local environments, affect public health, and carry pollutants and pathogens across continents.

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.

Breathing is going to get tougher as hotter temps mean more air pollution, says study

Not all pollution comes from people. When global temperatures increase by 4°C, harmful plant emissions and dust will also increase by as much as 14%, according to new UC Riverside research.

The research does not account for a simultaneous increase in human-made sources of air , which has already been predicted by other studies.

"We are not looking at human emissions of air pollution, because we can change what we emit," said James Gomez, UCR doctoral student and lead author of the study. "We can switch to electric cars. But that may not change air pollution from plants or dust."

Details of the degradation in future air quality from these have now been published in the journal Communications Earth & Environment. About two-thirds of the future pollution is predicted to come from plants.

All plants produce chemicals called biogenic volatile organic compounds, or BVOCs. "The smell of a just-mowed lawn, or the sweetness of a ripe strawberry, those are BVOCs. Plants are constantly emitting them," Gomez said.

On their own, BVOCs are benign. However, once they react with oxygen, they produce . As they're inhaled, these aerosols can cause and childhood asthma, as well as heart disease and lung cancer in adults.

There are two reasons plants increase BVOC production: increases in and increases in temperatures. Both of these factors are projected to continue increasing.

To be clear, growing plants is a net positive for the environment. They reduce the amount of in the atmosphere, which helps control global warming. BVOCs from small gardens will not harm people.

"Your lawn, for example, won't produce enough BVOCs to make you sick," Gomez explained. "It's the large-scale increase in carbon dioxide that contributes to the biosphere increasing BVOCs, and then organic aerosols."

The second-largest contributor to future air pollution is likely to be dust from the Saharan desert. "In our models, an increase in winds is projected to loft more dust into the atmosphere," said Robert Allen, associate professor of Earth and Planetary Sciences at UCR and co-author of the study.

As the climate warms, increased Saharan dust is likely to get blown around the globe, with higher levels of dust in Africa, the eastern U.S., and the Caribbean. Dust over Northern Africa, including the Sahel and the Sahara, is likely to increase due to more intense West African monsoons.

Both organic aerosols and , as well as sea salt, , and sulfate, fall into a category of airborne pollutants known as PM2.5, because they have a diameter of 2.5 micrometers or less. The increase in naturally sourced PM2.5 pollution increased, in this study, in direct proportion to CO2 levels.

"The more we increase CO2, the more PM2.5 we see being put into the atmosphere, and the inverse is also true. The more we reduce, the better the air quality gets," Gomez said.

For example, if the climate warms only 2°C, the study found only a 7% increase in PM2.5. All of these results only apply to changes found in air quality over land, as the study is focused on human health impacts.

The researchers hope the potential to improve air quality will inspire swift and decisive action to decrease CO2 emissions. Without it, temperatures may increase 4°C by the end of this century, though it's possible for the increase to happen sooner.

Gomez warns that CO2 emissions will have to decrease sharply to have a positive effect on future air quality.

"The results of this experiment may even be a bit conservative because we did not include climate-dependent changes in wildfire emissions as a factor," Gomez said. "In the future, make sure you get an air purifier."

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.

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.

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.

Title:

Content: The United Nations reports that the amount of sand and dust in the global air will increase in 2022.
The increase was attributed to increased emissions in several regions, including central and western Africa, the Arabian Peninsula, the Iranian plateau and northwestern China.
The United Nations World Meteorological Organization (WMO) has called for more research on how climate change is exacerbating dust storm hotspots.
According to the World Meteorological Organization ’ s Airborne Sand and Dust Bulletin, dust storms are caused by human activities such as rising temperatures, drought, increased evaporation and poor land management.
These activities reduce soil moisture and create favorable conditions for the formation of dust storms.
The annual report of the World Meteorological Organization examines the incidence and hazards of dust storms and their impact on society.
According to the report, the average annual concentration of dust on the global dust surface in 2022 is slightly higher than in 2021.
Last year the figure was 13.8 micrograms per cubic meter, compared to 13.5 micrograms per cubic meter in 2021.
The report highlights that about 200 billion tons of dust enters the atmosphere each year, affecting air quality and darkening the skies over thousands of kilometers of outlying areas.
These dust storms have significant impacts on the economy, ecosystems, weather and climate.
Although some dust is a natural phenomenon, a large part of it is caused by poor water and land management.
Notably, the bulletin details three major events in 2022. In 3,500 months, unusual dust storms occurred over Spain and Portugal in North Africa, with peak concentrations exceeding 50 micrograms per cubic meter per hour, well above the EU daily limit.
In October, the Middle East and the eastern United States experienced severe dust storms, affecting visibility and farmland.
World Meteorological Organization President Petrie Taras highlighted the adverse effects of dust storms on health, transport and agriculture, and stressed the need for further research into the relationship between dust storms and climate change, which is relatively unexplored.
The World Meteorological Organization has called for the global implementation of early warning systems for weather hazards, combining sandstorm forecasting skills and early warning services to mitigate the effects of worsening climate change.
