Half of world’s children exposed to at least three climate hazards, Unicef says

Half of World's Children Exposed to Multiple Climate Hazards, UNICEF Reports

Half of world s children exposed - According to a recent UNICEF report, over half of the world's children are now experiencing at least three concurrent climate-related threats that jeopardize their well-being. These include extreme weather events, rising temperatures, and natural disasters such as floods and droughts. The findings highlight a growing crisis, with more than one billion children globally affected by these overlapping dangers. As the climate crisis intensifies, the impact on young lives becomes increasingly pronounced, disrupting education, health, and even survival.

A Real-Life Example in Papua New Guinea

In the Rigo district of Papua New Guinea, a stark illustration of the report’s claims unfolds. A once-vital footbridge, destroyed by heavy rains in 2012, has left children in the community stranded. To access school, many must swim across the Kemp Welch river, which is now teeming with crocodiles. This daily challenge underscores the immediate consequences of climate change on children’s routines and safety.

“During our periods, our elders do not allow us to cross the river to attend our classes as they think it will attract crocodiles … My dream is to become a teacher or pilot. We want a new bridge so we can go to school safely every day,” said Lorna, a 15-year-old student.

Unicef staff noted that the community owns only a few small boats, but the youngest children are given priority when crossing the river. For older students like Lorna, the journey is more perilous. The report emphasizes that such scenarios are not isolated, but part of a global pattern where children face escalating climate risks.

Infrastructure Strains and Climate Challenges

UNICEF’s analysis reveals that climate change is placing unprecedented pressure on infrastructure. Key roads and bridges are increasingly vulnerable to damage, creating barriers for children in regions already struggling with limited resources. In the case of the Kemp Welch river, the absence of a bridge has forced the community to adapt by relying on makeshift solutions, but these are often insufficient.

Charlie Vali David, the headteacher at the local school, described the toll of the bridge’s loss. “During monsoon season, heavy currents, dead trees, and debris block the river—causing injury and death,” he explained. “Many children fall sick from the cold, dirty river water. That creates a learning gap, especially for females, who are more likely to take on additional responsibilities at home.”

“The loss of this bridge has disrupted not just our education system, but our entire way of life. Children are forced to navigate dangerous conditions simply to attend classes,” said Vali David.

The report further warns that the compounding effects of climate hazards are intensifying. Rising temperatures and extreme weather events are making infrastructure failures more frequent, leaving children without reliable access to essential services. This trend is observed in various parts of the world, from rural areas to urban centers, as climate change reshapes daily life.

Global Exposure to Climate Threats

The Children’s Climate Risk Report identifies eight specific climate hazards that children are exposed to: coastal floods, droughts, extreme heat, fires, heatwaves, river floods, sand and dust storms, and tropical storms. These hazards are not evenly distributed; the Sahel region of Africa stands out as one of the most severely impacted areas. Over 4 million children there face the triple threat of heatwaves, extreme heat, and sand and dust storms, which combine to create a particularly harsh environment for learning and survival.

In Asia, children in countries like Bangladesh, Myanmar, and Pakistan are encountering the highest number of climate-related risks. The report found that these regions are grappling with frequent flooding, prolonged droughts, and extreme weather events that disrupt communities. Even in high-income nations, the threat is significant. In Italy, for instance, more than 6 million children are exposed to prolonged heatwaves and droughts, which strain healthcare systems and affect agricultural productivity.

While the report highlights the most vulnerable regions, it also stresses that children in wealthy countries are not immune to climate shocks. The study shows that almost every child worldwide—regardless of geography or economic status—is exposed to at least one climate hazard. However, the most severely affected children face more than six hazards in their lifetime, creating a complex web of challenges.

Protecting Children’s Futures

UNICEF’s executive director, Catherine Russell, underscored the urgency of the situation. “The lives of children continue to be upended by the impact of heatwaves, wildfires, droughts, and floods,” she stated. “Half of the world’s children are now living with at least three overlapping climate threats shaping their daily lives.”

The report calls for immediate action to safeguard children’s access to education and healthcare. Russell emphasized that governments and businesses must prioritize reducing emissions and enhancing climate adaptation strategies. “This analysis can help governments and decision-makers plan better and invest more effectively in resilient services,” she said. “When we strengthen health and education systems, and improve infrastructure with children in mind, we protect them from today’s climate threats and help secure their future.”

UNICEF’s plan includes advocating for policies that address both the causes and effects of climate change. By investing in adaptive measures, such as building climate-resilient infrastructure and improving early warning systems, the organization hopes to mitigate the impact on children. The report also highlights the need for global cooperation, as climate hazards transcend borders and affect communities in interconnected ways.

The findings serve as a wake-up call, urging stakeholders to recognize the disproportionate burden on children. As the climate crisis progresses, the report warns that without targeted interventions, future generations will face even greater challenges. The story of Lorna and her peers in Papua New Guinea is a poignant reminder of the human cost of inaction, and the need to ensure that children’s lives are not dictated by the forces of climate change.

UNICEF’s report is a critical tool for raising awareness and driving policy change. By mapping the exposure of children to climate hazards, it provides a roadmap for addressing these issues. The agency’s call to action emphasizes that protecting children’s access to education and health services is not just a matter of compassion, but a necessity for building a resilient and sustainable future.
