The world is paying an increasingly heavy price for the devastating effects of climate change. In the last five decades alone, global economic losses due to weather, climate, and water-related disasters have soared to an eye-watering $4.3 trillion. The death toll, though falling, remains tragically high with over 2 million people having lost their lives to these extreme events. As the planet continues to heat up, with 2024 marked as the hottest year on record, the financial toll of these disasters is only set to rise.

The problem isn’t just the scale of these losses, but the lack of adequate systems in place to mitigate them. Early warning systems, which are proven to reduce the economic and human costs of extreme weather, remain inaccessible to nearly half of the world’s countries. While the technology exists, the disparity in access to life-saving forecasting and warning systems is leaving millions vulnerable to storms, floods, wildfires, and droughts that could otherwise be anticipated.

“We are more than just weather forecasters,” said Celeste Saulo, Secretary-General of the World Meteorological Organization (WMO), which recently marked its 75th anniversary. “WMO makes the world safer, more secure, and prosperous.” Yet, despite decades of advancements in forecasting, gaps remain. Countries with limited resources struggle to set up the infrastructure needed to protect their populations, which often face the brunt of the most severe consequences of climate change.

In his message for World Meteorological Day, UN Secretary-General António Guterres highlighted the stark reality: “It is disgraceful that, in a digital age, lives and livelihoods are being lost because people have no access to effective early warning systems.” The warning from Guterres couldn’t be clearer: early warning systems are not luxuries. They are necessities—and crucial investments that offer nearly a ten-fold return.

The data is irrefutable. From satellite feeds to ocean buoys, billions of measurements are collected daily from across the globe. Yet, in many parts of the world, these critical insights into climate and weather patterns do not reach those who need them most. Gaps in observation networks and forecasting accuracy continue to undermine the ability of vulnerable communities to prepare for and respond to disasters.

WMO’s Early Warnings for All initiative seeks to address this crisis by ensuring that by 2027, every country, no matter how economically or technologically challenged, has access to effective early warning systems. As of 2024, 108 countries report some capacity for multi-hazard early warning systems—more than double the number from 2015. However, this progress is not fast enough to prevent future calamities. The economic costs of inaction are simply too high.

Key Data Points
$4.3 Trillion – Total global economic losses from weather, climate, and water-related hazards between 1970 and 2021.
2 Million+ – Number of lives lost to weather, climate, and water-related disasters between 1970 and 2021.
108 Countries – The number of countries with some capacity for multi-hazard early warning systems as of 2024, more than double the 52 countries in 2015.
$1 Investment in Early Warning Systems – The potential return on investment is nearly ten times the cost, according to UN Secretary-General António Guterres.
2024 – The year marked as the hottest year on record.
75 Years – The number of years the World Meteorological Organization (WMO) has been a UN specialized agency, working to improve global resilience to climate change.

Between 1970 and 2021, climate-related disasters cost the global economy $4.3 trillion—a figure that continues to climb year after year. Without early warnings, this loss is compounded by the inability of countries to adapt or respond in time, resulting in more widespread destruction and human suffering. But for every dollar invested in early warning systems, the potential savings and lives saved are immense.

“The staff of National Meteorological and Hydrological Services are like doctors and nurses – working 24/7 to safeguard and promote public well-being,” Saulo emphasized. These services are crucial for monitoring climate and weather changes and issuing warnings, but much of the world’s population still lacks access to these vital resources.

WMO’s call to action on World Meteorological Day, though after the fact, remains urgent: “We need high-level political support, increased technology sharing, greater collaboration between governments and businesses, and a major effort to scale-up finance,” said Guterres. He emphasized the importance of boosting the lending capacity of multilateral development banks to ensure that resources reach the nations most at risk.

As the planet faces increasingly volatile climate conditions, the economic costs of inaction are mounting. Without the necessary investment in early warning systems, millions will continue to suffer, and the global economy will pay the price. The time to act is now. Climate change may be an overwhelming challenge, but with the right systems in place, we can mitigate the damage, save lives, and protect our collective future.

In a move aimed at supporting ecological restoration in the Banni Grasslands, Gujarat, India, the State Forest Department has introduced 20 spotted deer into a protected 70-hectare area within the landscape. The translocation, conducted in collaboration with the wildlife conservation initiative Vantara, is part of an effort to enhance biodiversity in one of Asia’s largest and most fragile grassland ecosystems. Vantara is a wildlife conservation initiative founded by Anant Ambani, a board member of Reliance Industries, one of India’s largest conglomerates. Vantara operates the Greens Zoological, Rescue and Rehabilitation Centre in Jamnagar, which served as the source facility for the spotted deer.

The spotted deer, also known as chital (Axis axis), were translocated from Vantara’s ex-situ conservation facility in Jamnagar. They were moved in specially designed ambulances and released under the direct supervision of the Forest Department. Vantara provided logistical and veterinary support to ensure adherence to conservation protocols during the process.

The Banni Grasslands, stretching over 2,600 sq. km in Gujarat’s Kutch district, are a unique arid ecosystem that supports a range of wildlife. According to regional biodiversity surveys, 12 species of mammals have been recorded in the area, including six carnivores such as the Indian wolf and striped hyena, and two herbivores, including the Indian gazelle.

Forest officials and experts from Vantara jointly conducted a field assessment ahead of the deer release to evaluate habitat conditions and inform future rewilding strategies. The review included ecological suitability checks and outlined key habitat restoration measures.

Dr. Brij Kishor Gupta, Director of the Greens Zoological, Rescue and Rehabilitation Centre under Vantara, noted the importance of science-driven collaboration in the effort.

“This initiative reflects a collaborative approach to conservation, where scientific expertise and logistical support are combined to strengthen biodiversity in the Banni Grasslands. Contributing to government-led efforts, the focus remains on achieving meaningful conservation outcomes through partnerships grounded in shared objectives.”

The Gujarat Forest Department has been working to manage ecological pressures in Banni through habitat restoration, control of invasive species, and promotion of native grass growth—critical to sustaining herbivore populations and the carnivores that depend on them.

While the introduction of spotted deer is a notable milestone, experts emphasize that such rewilding interventions must be closely monitored. Ecologists point out that herbivore populations can influence vegetation dynamics, and the long-term impact on the grassland’s carrying capacity and predator-prey relationships remains to be studied.

For now, the project marks a rare instance of coordinated public-private conservation action in India’s grasslands—ecosystems often overshadowed by forests and wetlands in national conservation discourse. As such, it could serve as a model for future wildlife restoration efforts in similar landscapes.

How Barn Owls Brought Nature, Knowledge, and Heart to a South African Campus

At the University of the Free State, South Africa, a quiet conservation story unfolds above the bookshelves – reminding us that even academic spaces can grow wings.

High above the rows of books and hushed reading tables of the Sasol Library at the University of the Free State (UFS), something unexpected is taking flight. A pair of barn owls have made their home in the library’s roof, quietly raising their young and shifting the way an entire academic community sees its role in the world. Their story, both poetic and practical, is becoming a symbol of collaboration, compassion, and conservation.

The owls aren’t just guests—they’re catalysts. What began as a distressed bird outside the library in 2023 has transformed into a university-wide initiative blending science, storytelling, and shared stewardship.

“Our library is a living ecosystem”

For Prof Vasu Reddy, Deputy Vice-Chancellor: Research and Internationalisation, the owls are more than a charming anecdote.

“If we consider Shakespeare’s play, All’s Well That Ends Well, then the presence of the owls in the Sasol Library confirms another meaning of that play,”

“Love,” Prof Reddy says, “is not always considered noble, but is something persistent, and our library is not just a building, but a living ecosystem where precious documents, people, and even animals can interact, shape, and nurture our lives.”

That idea—that libraries are not only homes to knowledge, but habitats for life—is now echoed across campus.

A rescue that became a movement

The turning point came when Tanya Scherman, from the Centre for Teaching and Learning, spotted a sick owl near the library—likely a victim of secondary poisoning from a contaminated rodent.

“It appeared that the owl had been poisoned,” she recalls. “I phoned around trying to find more knowledgeable people who could help.”

Her outreach brought in a network of allies, including the Owl Rescue Centre in Pretoria, a local vet, and Prof Francois Deacon from the Department of Animal Sciences.

“As someone passionate about urban wildlife conservation, I saw a great opportunity – not just to support the owls, but to involve students in hands-on learning,” says Prof Deacon.

Together with his postgraduate students, Ruan Higgs and Kaitlyn Taylor, the team designed a custom nesting box and installed a motion-activated infrared camera to monitor owl activity safely. For Scherman, building the box was a family affair.

“I worked with my dad to build it,” she shares. “He’s an avid animal lover too… It was such a special moment to share with my family.”

From research to relationships

The project has already yielded tangible outcomes. In 2023, the owl pair successfully raised two owlets. This year, six eggs were laid—three owlets are visible so far.

“It captures feeding events, chick development, and parental behaviour,” says Prof Deacon. “This kind of passive monitoring is invaluable… These owls are teaching tools.”

Their footage has already formed the basis for student research on owl diet, nesting habits, and ecological adaptation. And the benefits go beyond science.

“What’s been most rewarding was how many people came together around this – from librarians to students to scientists. We built friendships, not just a nest box.”

Even librarian Hesma van Tonder joined a giraffe capture excursion with Deacon’s team. These moments, Deacon says, are where research and real-life adventure meet.

Symbols of wisdom – and survival

For Scherman, the owls touch something deeper than academic interest.

“My grandparents also had a special connection to owls… When we saw the baby owlets, I naturally felt like I was being promoted to an owl-granny!”

She also hopes to change cultural perceptions around these often-misunderstood birds.

“It’s understandable,” she says, “with their eerie calls, white faces, and ghost-like flight. But they are also messengers, protectors, and symbols of wisdom in many traditions.”

From reducing rodent populations naturally to serving as symbols of coexistence, barn owls bring both ecological and educational value.

“A single owl pair can eat hundreds of rodents in a breeding season,” says Prof Deacon. “We found remains of small birds and insects in their regurgitated pellets… which shows just how active and adaptive they are in an urban environment.”

But risks remain—road traffic, noise, and poisoning threaten their safety. That’s why Scherman and Deacon urge the campus community to be mindful.

“Don’t try to help an injured owl yourself,” says Scherman. “Rather contact Prof Deacon or me… We’re here to assist.”

“Awareness builds respect,” Prof Deacon adds. “Simple behaviours, such as keeping windows closed at night near the roost, go a long way.”

Where silence meets storytelling

As word spread, the initiative grew in meaning—turning the Sasol Library into more than a study space. It’s now a symbol of the university’s values in action.

“It is clear that what may be seen as a disruptive incident with an owl swooping into our library space is also a pedagogical and deeply conservation touchdown,” reflects Prof Reddy.

“Our barn owl event tells us that our library is also a space where silence meets storytelling… where every creature’s story has a rightful place.”

Looking forward

The team is already dreaming bigger. Deacon hopes to expand the project into green corridors, rooftop biodiversity zones, and support for species like bats and pollinators. He sees it as the start of a new kind of campus culture—one rooted in curiosity and care.

“If our university matters and is to remain meaningful,” Prof Reddy says, “our accidental visitors have given new impetus to the fact that our library space holds our stories, and they are making places for new ones as part of our responsible societal futures.”

As the owls continue their quiet vigil above the Sasol Library, they leave more than pellets behind. They leave a legacy of connection—between people, nature, and the pursuit of knowledge. And in that space, where a library became a nest, a new kind of learning has taken flight.

Meltwater ponds might have sheltered life during earth’s deep freeze

During this time, the planet was believed to be encased in ice, with global temperatures plummeting to as low as -50°C

In a study published in Nature Communications, scientists from MIT have proposed that shallow meltwater ponds may have provided critical refuges for early complex life during one of Earth’s most extreme ice ages — the “Snowball Earth” period, which occurred between 635 and 720 million years ago.

During this time, the planet was believed to be encased in ice, with global temperatures plummeting to as low as -50°C. Despite the harsh conditions, complex cellular life — known as eukaryotes — managed to survive. The new research suggests that these life forms could have found sanctuary in small, briny pools formed on the surface of equatorial ice sheets.

“Meltwater ponds are valid candidates for where early eukaryotes could have sheltered during these planet-wide glaciation events,” said lead author Fatima Husain, a graduate researcher in MIT’s Department of Earth, Atmospheric and Planetary Sciences, in a media statement. “This shows us that diversity is present and possible in these sorts of settings. It’s really a story of life’s resilience.”

The team drew parallels between ancient equatorial ice sheets and modern Antarctic conditions. They studied contemporary meltwater ponds on Antarctica’s McMurdo Ice Shelf — an area first dubbed “dirty ice” by explorers in the early 20th century. These ponds, formed by sun-warmed dark debris trapped within surface ice, provided a modern analog to the possible melt environments of the Cryogenian Period.

Samples taken from these Antarctic ponds revealed clear signatures of eukaryotic life. Using chemical and genetic analysis, including the identification of sterols and ribosomal RNA, the researchers detected algae, protists, and microscopic animals — all descendants of early eukaryotes. Each pond supported unique communities, with differences shaped largely by salinity levels.

“No two ponds were alike,” Husain noted. “There are repeating casts of characters, but they’re present in different abundances. We found diverse assemblages of eukaryotes from all the major groups in all the ponds studied.”

These findings suggest that meltwater ponds — overlooked in previous hypotheses — could have served as vital “above-ice oases” for survival and even diversification during Snowball Earth.

“There are many hypotheses for where life could have survived and sheltered during the Cryogenian, but we don’t have excellent analogs for all of them,” Husain explained. “Above-ice meltwater ponds occur on Earth today and are accessible, giving us the opportunity to really focus in on the eukaryotes which live in these environments.”

The study was co-authored by MIT’s Roger Summons, Thomas Evans (formerly MIT), Jasmin Millar of Cardiff University, Anne Jungblut of the Natural History Museum in London, and Ian Hawes of the University of Waikato in New Zealand.

By uncovering how life may have persisted through Earth’s frozen past, the research not only deepens understanding of our planet’s history — it may also help inform the search for life on icy worlds beyond Earth.
