The General Directorate of Civil Defense said the warning was based on projections from the National Center for Meteorology, which expects moderate to heavy rainfall across regions including Makkah, Riyadh, Madinah, Qassim, Hail, Tabuk, the Eastern Province, Northern Borders, Al-Jouf, Al-Baha, Asir, Jazan and Najran.

Authorities said the unstable weather could trigger flash flooding, hailstorms and strong downdrafts capable of generating dust storms that may significantly reduce visibility.In response, Hafar Al-Batin University suspended in-person classes on Monday, shifting to remote learning in its main campus and affiliated colleges in Khafji and Al-Nairyah following meteorological advisories.

The civil defense agency advised residents to remain in safe locations, avoid flood-prone areas and refrain from entering valleys or swimming in affected zones, while monitoring official updates.The warnings follow a series of escalating alerts issued over the weekend, including a red alert for the Madinah region, where forecasters predicted intense rainfall, hail and near-zero visibility conditions.

Weather authorities said the system developed over northern and western regions on Saturday before expanding into central and eastern areas on Sunday, bringing widespread rain and dust-laden winds.

Officials said they continue to monitor the situation closely as adverse weather conditions persist, urging the public to prioritize safety precautions.

Wearing a helmet fitted with a headlamp and a protective mask, molecular biologist Raúl da Silva Armando Chomela moves through the confined, low-light interiors of cave systems in central Mozambique, examining bat populations and their byproducts as part of a broader scientific effort to understand subterranean ecosystems.

Chomela, originally from the port city of Beira, has spent two years conducting research inside caves located in and around Gorongosa National Park, a 4,000 square kilometre conservation area recognized for its biodiversity.

His work focuses on bats and guano, a substance formed from accumulated bird and bat excrement that serves as a complex biological environment.“Guano is far more than just bat droppings,” Chomela said in an interview, describing it as a dynamic ecosystem.

According to his observations, guano supports a wide range of cave-dwelling organisms, including beetles, amphibians and microorganisms that have adapted to life in conditions without sunlight.

The caves in Gorongosa represent highly specialized environments. Organisms found within them have evolved to survive in stable, low-light conditions with distinct microbiomes that differ significantly from surface ecosystems.

These systems are characterized by limited external input and reliance on internal nutrient cycles, often driven by organic deposits such as guano.Chomela’s research involves entering narrow passages and descending into enclosed spaces using ropes and ladders, often without full knowledge of the terrain or species present.

According to the park’s science department, the cave networks in the region extend across approximately 183 square kilometres, forming interconnected underground systems.

More than 100 bat species have been identified in Gorongosa, although there is no precise data on how many inhabit these caves. One site, known as Tombo Aphale 5, has been extensively studied and hosts an estimated population of over 10,000 bats.

The cave is also the site of an active archaeological excavation, indicating its broader scientific relevance beyond ecological research.Gorongosa National Park was established in 1960 during Portuguese colonial administration.

Following Mozambique’s independence in 1975, conservation was not prioritized under the ruling Frelimo party. Two years later, the park became a strategic location during the country’s civil war, which involved government forces and the insurgent group Renamo.

Renamo, initially formed with support from the Rhodesian government under Ian Smith and later backed by apartheid-era South Africa, operated within the park’s terrain. During the conflict, armed groups relied on wildlife for sustenance, leading to widespread depletion of animal populations.

By the end of the war, which lasted more than 15 years, approximately 95% of the park’s wildlife had been lost, including nearly all of its estimated 5,500 hippos.The effects of the conflict extended beyond environmental damage.

Local communities experienced forced recruitment and other human rights abuses during the war, contributing to long-term social and economic challenges in the region.

In the decades since the conflict ended, Gorongosa has become the focus of sustained conservation and restoration efforts. These initiatives have involved partnerships between international institutions and Mozambican researchers, aiming to rebuild ecosystems and support local development.

One such initiative is the Paleo-Primate Project, established in 2018 as a collaboration between the University of Oxford and Gorongosa National Park. The project is led by Susana Carvalho and integrates research in archaeology, ecology and geology.

It also provides training and employment opportunities for local researchers and students.Carvalho said the broader Gorongosa Restoration Project has become a significant employer in the region, contributing to economic stability.

The project supports scientific research while also engaging local communities in conservation efforts.Chomela joined Gorongosa’s biodiversity laboratory in 2022 before becoming part of the Paleo-Primate Project in 2025.

His research spans multiple disciplines, including the use of environmental DNA to reconstruct historical ecosystems and metabarcoding techniques to analyze genetic material from bats and primates.

He is currently a first-year doctoral student at the University of Porto in Portugal, with his research based at the EO Wilson Laboratory in Chitengo, located within the park. In addition to his academic work, he leads the genetics laboratory at the facility, contributing to ongoing studies of biodiversity and ecosystem dynamics.

Chomela has also raised concerns about the potential overexploitation of guano resources. While the material is valued for its agricultural and economic uses, he noted that excessive harvesting could alter the composition of cave ecosystems.

“When they see the guano, they see money,” he said, adding that unsustainable extraction could disrupt the balance of species that depend on it.He emphasized the importance of building a scientific foundation to inform conservation practices and community engagement.

“We want a scientific base to convince the community,” he said, referring to efforts to align local economic interests with environmental sustainability.

The integration of scientific research, conservation policy and community involvement remains central to ongoing work in Gorongosa, as researchers continue to document and restore one of Africa’s most ecologically significant regions.

Singapore (Reuters) – The target of keeping long-term global warming within 1.5 degrees Celsius (2.7 Fahrenheit) is moving out of reach, climate experts say, with nations failing to set more ambitious goals despite months of record-breaking heat on land and sea.

As envoys gathered in Bonn in early June to prepare for this year’s annual climate talks in November, average global surface air temperatures were more than 1.5C above pre-industrial levels for several days, the EU-funded Copernicus Climate Change Service (C3S) said.

Though mean temperatures had temporarily breached the 1.5C threshold before, this was the first time they had done so in the northern hemisphere summer that starts on June 1. Sea temperatures also broke April and May records.

“We’ve run out of time because change takes time,” said Sarah Perkins-Kirkpatrick, a climatologist at Australia’s University of New South Wales.

As climate envoys from the two biggest greenhouse gas emitters prepare to meet next month, temperatures broke June records in the Chinese capital Beijing, and extreme heatwaves have hit the United States.

Parts of North America were some 10C above the seasonal average this month, and smoke from forest fires blanketed Canada and the U.S. East Coast in hazardous haze, with carbon emissions estimated at a record 160 million metric tons.

In India, one of the most climate vulnerable regions, deaths were reported to have spiked as a result of sustained high temperatures, and extreme heat has been recorded in Spain, Iran and Vietnam, raising fears that last year’s deadly summer could become routine.

Countries agreed in Paris in 2015 to try to keep long-term average temperature rises within 1.5C, but there is now a 66% likelihood the annual mean will cross the 1.5C threshold for at least one whole year between now and 2027, the World Meteorological Organization predicted in May.

‘Quadruple Whammy’

High land temperatures have been matched by those on the sea, with warming intensified by an El Nino event and other factors.

Global average sea surface temperatures hit 21C in late March and have remained at record levels for the time of year throughout April and May. Australia’s weather agency warned that Pacific and Indian ocean sea temperatures could be 3C warmer than normal by October.

Global warming is the major factor, said Piers Forster, professor of climate physics at the University of Leeds, but El Nino, the decline in Saharan dust blowing over the ocean and the use of low-sulphur shipping fuels were also to blame.

“So in all, oceans are being hit by a quadruple whammy,” he said. “It’s a sign of things to come.”

Thousands of dead fish have been washing up on Texan beaches and heat-induced algal blooms have also been blamed for killing sea lions and dolphins in California.

Warmer seas could also mean less wind and rain, creating a vicious circle that leads to even more heat, said Annalisa Bracco, a climatologist at the Georgia Institute of Technology.

Though this year’s high sea temperatures are caused by a “perfect combination” of circumstances, the ecological impact could endure, she said.

“The ocean is going to have a very slow response as it accumulates (heat) slowly but also keeps it for very long.”

The Road To Dubai

Climate experts say the extent and frequency of extreme weather is increasing, and this year has also seen punishing droughts across the world, as well as a rare and deadly cyclone in Africa.

The Worldwide Fund for Nature, however, warned of a “worrying lack of momentum” during climate talks in Bonn this month, with little progress made on key issues like fossil fuels and finance ahead of November’s COP28 climate talks in Dubai.

“It was very detached from what was going on outside of the building in Bonn – I was very disappointed by that,” said Li Shuo, Greenpeace’s senior climate adviser in Beijing.

“We are really getting to the moment of truth … I am hoping that the sheer reality will help us change people’s moves and change the politics.”

Talks between the United States and China could resume next week with U.S. climate envoy John Kerry set to visit Beijing, though few expect it to add momentum to climate negotiations.

“This is more a trust-building exercise,” Li said. “I don’t think either side will be able to push the other side to say much more than they are willing to do – the politics won’t allow that.”

The COP27 UN climate summit began on Monday in the Red Sea town of Sharm el-Sheikh, in the hope of averting the worst impacts of climate change. World leaders, policymakers and delegates from nearly 200 countries have gathered to discuss the future of the planet.

Food resources for the African continent are set to be a key point of discussions. To unpack the importance of what extra resources could mean for Africa, we’re joined by the new head of the UN International Fund for Agricultural Development, Alvaro Lario.

Abuja — According to a revised toll announced on Sunday, it is now known that more than 600 people died in Nigeria’s worst floods in a decade.

More than 1.3 million people have also been evicted from their homes as a result of the tragedy, according to a statement from Nigeria’s ministry of humanitarian affairs.
