Air pollution in the Thai capital forced the closure of more than 350 schools on Friday, city authorities said, the highest number in five years.

Bangkok officials announced free public transport for a week in a bid to reduce traffic in a city notorious for noxious exhaust fumes.

Seasonal air pollution has long afflicted Thailand, like many countries in the region, but this week's hazy conditions have shuttered the most schools since 2020, said AFP.

"Bangkok Metropolitan Administration has closed 352 schools across 31 districts due to air pollution," the authority said in a message shared on its official LINE group.

On Thursday, more than 250 schools in Bangkok were closed due to pollution, as officials urged people to work from home and restricted heavy vehicles in the city.

Air pollution hits the Southeast Asian nation seasonally, as colder, stagnant winter air combines with smoke from crop stubble burning and car fumes.

By Friday, the level of PM2.5 pollutants -- cancer-causing microparticles small enough to enter the bloodstream through the lungs -- hit 108 micrograms per cubic meter, according to IQAir.

The reading makes the Thai capital the world's seventh-most polluted major city currently.

The World Health Organization (WHO) recommends 24-hour average exposures should not be more than 15 for most days of the year.

By Friday morning, 352 of the 437 schools under the Bangkok Metropolitan Authority had shut their doors, affecting thousands of students.

Interior Minister Anutin Charnvirakul on Thursday ordered a ban on stubble burning -- intentionally burning leftover crops to clear fields -- with those responsible risking legal prosecution.

In another bid to curb pollution, a government minister said Friday that public transport in Bangkok would be free for a week.

The capital's Skytrain, metro, light rail system and bus services will be free to users from Saturday, transport minister Suriya Juangroongruangkit told reporters.

"We hope this policy will help reduce pollution."

Prime Minister Paetongtarn Shinawatra, who is currently attending the World Economic Forum in Switzerland, called for tougher measures to tackle pollution on Thursday, including limiting construction in the capital and seeking cooperation from nearby countries.

Regional problem

Cities in neighboring Vietnam and Cambodia also ranked high on IQAir's most-polluted list on Friday, with Ho Chi Minh second and Phnom Penh fifth.

Cambodia's environment ministry confirmed on Friday that the air quality in Phnom Penh and three other provinces had reached a "red level", meaning highly polluted.

The ministry said in a statement that the air pollution was caused by climate change, waste incineration and forest fires, and urged the public to monitor their health and avoid outdoor activities.

Air pollution has closed schools across other parts of Asia recently -- specifically Pakistan and India

Nearly two million students in and around New Delhi were told to stay home in November after authorities ordered schools to shut because of worsening air pollution.

Pakistan's most populated province of Punjab in November closed schools in smog-hit major cities for two weeks, with thousands hospitalized as air pollutants hit 30 times the level deemed acceptable by the WHO.

Bangkok's school closures come as UNICEF said in a report that 242 million children's schooling was affected by climate shocks in 2024.

Climate change can worsen the problem of air pollution which is considered a "secondary impact of climate-induced hazards", according to the report published Friday.

The Saudi Green Initiative (SGI) Day, observed annually on March 27 following a Cabinet decision, reflects the Kingdom's commitment to establishing a culture of sustainability, enhancing national environmental efforts, and encouraging all sectors to achieve sustainable development goals in line with Vision 2030, SPA reported.

The initiative recently achieved a significant national milestone by rehabilitating one million hectares of degraded land through the National Greening Program, overseen by the National Center for Vegetation Cover Development and Combating Desertification. This objective aims to expand vegetation cover, reduce desertification, improve quality of life, and enhance the natural capacity of local environments to adapt to climate change.

The achievement is an extension of the Kingdom's broader efforts to protect natural resources, reduce emissions, promote reliance on clean energy, and preserve biodiversity, thereby strengthening Saudi Arabia's regional and international standing in environmental action.

Over the past year, the initiative has continued to make tangible progress. More than 159 million trees were planted across the Kingdom, and environmental reserves saw the birth of Arabian oryx calves for the third consecutive year. Furthermore, the National Water Efficiency and Conservation Center currently saves 120,000 cubic meters of water daily, with plans to increase this capacity to 300,000 cubic meters.

These combined efforts align with the objectives of Vision 2030 and contribute to strengthening the Kingdom’s regional and international standing in environmental sustainability.

SGI Day is observed annually to highlight the initiative’s achievements, review its future goals, and encourage broad sector participation in environmental efforts and sustainable development.

These efforts reflect the Kingdom’s approach to environmental and climate action, driven by the Saudi Green Initiative and the Middle East Green Initiative, both launched by Prince Mohammed bin Salman bin Abdulaziz Al Saud, Crown Prince and Prime Minister, underscoring its ongoing commitment to supporting the transition toward a more sustainable development model.

Observations made by a satellite operated by the US and French space agencies shortly after a strong earthquake struck off Russia's Kamchatka Peninsula last year are giving scientists a better understanding of how tsunamis originate and propagate.

The researchers said the findings may help improve understanding of future tsunamis and earthquakes at subduction zones, particularly near the ocean trench where two tectonic plates meet and one slides beneath the other. The strongest tsunamis often are generated by such quakes.

The magnitude 8.8 quake struck on July 29, 2025, triggering a tsunami that spread across the Pacific Ocean. A tsunami - a series of extremely long and powerful ocean waves - is caused by large movements of the seafloor that push water up or down, often during earthquakes or landslides that occur under water.

The NASA-CNES Surface Water and Ocean Topography, or SWOT, satellite ‌made its observations ‌within 70 minutes of the start of the earthquake. It observed not ‌only ⁠the leading wave ⁠of the tsunami, but also a distinct pattern of smaller waves trailing behind it.

Such wave patterns had long been predicted in computer models and theoretical studies, but had been difficult to confirm with real-world observations, the researchers said.

"I believe SWOT represents a new lens for observing and studying tsunamis and their generation," said Ignacio Sepúlveda, a professor of coastal engineering at San Diego State University and lead author of the study published this week in the journal Science.

"It is also likely to improve our understanding of the physical mechanisms that generate tsunamis, including earthquakes," ⁠Sepúlveda added.

Traditional deep-ocean pressure sensors and other satellites have limitations in coverage ‌and measurement, making it difficult to capture the full structure of ‌the waves, especially near the trench, the researchers said.

SWOT scans a wide swath of the ocean, producing two-dimensional maps ‌of sea surface height. This allows scientists to see the shape, direction and spacing of tsunami waves ‌in much greater detail.

Tsunamis are among the strongest and most destructive natural forces, with powerful waves radiating from a point of origin outward in all directions. These waves can cause damaging and deadly coastal flooding.

The tsunami in this study did not cause significant loss of life, but others have caused huge death tolls such as the 2004 Indian Ocean ‌tsunami that killed some 230,000 people.

The July 2025 tsunami originated within about 10 kilometers (six miles) of the trench, the place in the seafloor ⁠where two tectonic plates intersect, ⁠the researchers found. This location could not previously be determined using traditional land-based instruments or sparse sensors on the seafloor alone.

Earth's surface is made up of immense plates that move very gradually in a geological process called plate tectonics.

The researchers found that when earthquake-caused movement extends close to the trench, it can generate shorter waves that travel more slowly and spread out over time, forming a trailing pattern behind the main tsunami front. This behavior means that different parts of the wave move at different speeds, with longer waves moving more quickly and leading, while shorter ones lag behind.

The study also showed that the strength of the trailing waves increases when earthquake movement extends closer to the trench, suggesting these waves are linked to where and how the tsunami was generated near the trench.

"This opens a new window to understand in a better way what happens with earthquakes and tsunamis near the trench," Sepúlveda said, referring to SWOT observations. "In the future, this knowledge will allow us to improve models we use to evaluate tsunami hazards in coastal communities and make them more resilient."

Gabon Battles for Baby Sea Turtles’ Survival

Small enough to fit in the palm of your hand, newly hatched sea turtles emerged on a Gabonese beach to embark on the treacherous 10-meter (33-foot) scramble across the sand to the ocean.

"The survival rate for turtles is one in 1,000," Francois Boussamba, a Gabonese turtle expert and head of the NGO Aventures Sans Frontieres (Adventures Without Borders), told AFP, scouring for nests.

Conservationists from NGOs and the national parks agency patrol Gabon's beaches daily during the nesting season to protect the turtles' nests.

Those under threat are moved to a hatchery, a fenced enclosure near the sea, where the eggs are kept safe until they are ready to hatch.

On Pongara National Park's white sandy beaches, about 30 minutes by boat from the capital Libreville, conditions are optimal for nesting: wild coastline, a favorable equatorial climate and an open ocean beach with gentle slopes, ideal for the females.

But dangers lurk. Nests are threatened by coastal erosion due to encroaching sea levels, or myriad predators such as crabs and birds that prevent the eggs from reaching their 60-day incubation period, Boussamba said.

"The chances of survival are tiny," he said.

- Muscle up -

In Libreville, every morning around 7:00 am, volunteers from the Project Turtles Tahiti Gabon association crisscross the beach and check the nests in the hatchery.

After one has hatched, the baby turtles have to be moved so they can reach the sea -- but they are never put straight into the water.

"They need to build up their muscles so they can swim in the ocean," volunteer Clemence said.

Four species of turtles -- green, olive ridley, hawksbill and leatherback -- come to nest along Gabon's 900 kilometers (560 miles) of coastline from October to April.

It has the highest nesting density on the African continent, according to the US-based NGO Wildlife Conservation Society.

Gabon is the world's leading nesting site for the leatherback turtle, the largest of the species and listed as threatened by the International Union for Conservation of Nature (IUCN).

In addition to predators, sea turtles are also threatened by human activities, from plastic pollution to industrial fishing and poachers.

By watching over the eggs, the rangers in Pongara help ensure "the survival of this species", Edouard Moussavou, Pongara park's deputy director, said.

- Unpaid wages -

Since 2013, Gabon's conservation efforts had received funding from the United States, notably through the US Fish and Wildlife Service, an agency responsible for biodiversity.

"If there are turtles, it means our ecosystem is sound and healthy," Boussamba said.

But since the suspension of grants by the administration of US President Donald Trump, "turtle monitoring activities have stopped or slowed down drastically", Moussavou said.

"There will be fewer staff, less data, and that really creates difficulties for us," he said.

Additionally, there have been delays in paying the staff of the National Agency for National Parks (ANPN), which manages the country's 13 parks, according to Sosthene Ndong Engonga, secretary-general of the National Union of Gabonese Ecoguards.

The around 580 eco-rangers regularly go unpaid.

"Even when there is money, we have to make a big fuss to get our salaries," he said, adding he battled with the treasury last month for back pay.

The eco-rangers, who are crucial for the conservation of Gabon's biodiversity, face having "to give everything up," Engonga warned. "We have expenses we can no longer cover," he said.

On Pongara beach, 40-year-old Alain Banguiya carries out night patrols, hoping to see a leatherback turtle emerge from the water to lay her eggs in the sand.

An eco-ranger since 2015, he has not been paid for two months but says that giving up is out of the question.

"We have a duty to fight to the end, to keep our spirits up," he said. "Despite the obstacles, we stay the course: conservation."
