Science / SOURCE REPORTThe ozone layer protects life on Earth from harmful ultraviolet radiation. In the 1980s, scientists found that it was thinning, and the cause was traced to industrial chemicals. Governments agreed to phase them out, and the layer is now on a path to recovery. It is one of the clearest successes of international environmental cooperation. […]
Science / SOURCE REPORTWhen carbon dioxide enters the atmosphere, a substantial share of it dissolves in the ocean. That absorption has slowed warming and it has changed the chemistry of seawater, making it more acidic. The process is called ocean acidification, and it is a consequence of emissions that receives far less attention than temperature. The change is […]
Science / SOURCE REPORTPermafrost is ground that stays frozen for at least two consecutive years, and it covers a large share of the northern hemisphere. It holds enormous quantities of organic carbon, accumulated over thousands of years. As the ground warms, that carbon can be released as carbon dioxide and methane, adding to the warming that caused the […]
Science / SOURCE REPORTFood security is usually discussed in terms of harvests, prices and trade. Beneath all of them lies soil, a thin layer of living material that takes centuries to form and can be lost in a few seasons. Degraded soil produces less, holds less water and releases carbon, which makes it a climate issue as well […]
Science / SOURCE REPORTAntimicrobial resistance — the ability of bacteria and other microbes to survive the drugs designed to kill them — is one of the most serious threats to global health, and it keeps getting worse. The World Health Organization lists it among the top global health threats, and surveillance shows resistance rising in many countries. The […]
Science / SOURCE REPORTEarth-system data is widely available and widely misread. Scale, uncertainty and processing choices shape what any map shows — and reading them is a skill.
Science / SOURCE REPORTUNESCO's Recommendation on Open Science treats access as one part of a wider system: infrastructure, documentation, capacity and equity determine whether openness works.
Science / SOURCE REPORTFAO's forest assessment standardises reporting on forest area and change. But area is not condition — plantations, degradation and social value sit outside a hectare count.
Science / SOURCE REPORTNational vaccination coverage is an average. Gaps by district, income, age and disruption can hide inside a high national figure.
Science / SOURCE REPORTWHO's World Mental Health Report treats mental health as a system problem. Workers, affordability, rights safeguards and social conditions all shape whether care reaches people.
