U.N. highlights climate risks to children and food systems; FAO, Human Rights Office and UNICEF release new findings

The U.N. secretary‑general delivered a video message to the Austria World Summit warning the world is likely to overshoot the 1.5°C limit and urging a rapid, fair shift from fossil fuels to renewables, the U.N. spokesperson said.

UNICEF released a report finding nearly half the world’s children—about 1.1 billion—are exposed to at least three overlapping climate hazards that threaten health, education and survival, with drought and extreme heat the most common combination affecting more than 296 million children.

The Food and Agriculture Organization reported a record‑high $184 billion trade in aquatic animal products, rivaling terrestrial meat trade in value, but warned that climate change, environmental degradation and other shocks could reduce exploitable fish biomass by roughly 10% in many regions by 2050 under high‑emission scenarios.

The U.N. Human Rights Office published findings on anti‑personnel mines, noting at least 58 states and territories contaminated in 2025 and reporting that landmines and explosive remnants killed an estimated 1,945 people and injured 4,325 in 2024. The U.N. urged states to uphold relevant international law and support survivors.
