Microplastics likely reach Antarctic waters and ice via ocean currents and human activity, but data are sparse. Standardised sampling campaigns and analytical pipelines are required.

Weather, ice conditions, and human activity data are not always integrated for decision-makers. Shared operational dashboards could improve safety and efficiency.

Parties meet with limited time and information to address increasingly complex issues. Decision-support tools and horizon-scanning platforms can improve agenda-setting.

Sector-by-sector rules may miss combined pressures. Integrated cumulative-impact planning platforms could improve governance.

The absence of robust, context-adapted solutions for education approaches that build the capacity of local institutions to manage climate risks creates cascading risks across interconnected human and natural systems. Key missing elements include durable performance, low lifetime cost, and governance arrangements capable of sustaining impact beyond pilot stages.

Public procurement and justice systems sometimes fail to sanction wrongdoing. Transparency and civic-monitoring platforms can strengthen accountability.

Key ports like Rotterdam and Hamburg face capacity and digitalisation challenges that raise costs and delays. Port-community systems and real-time logistics dashboards could address bottlenecks.

Bridges, tunnels, and rail lines built decades ago require expensive renovation at a time of fiscal pressure. Asset-condition mapping and lifecycle-finance tools can prioritise investment.

Waiting lists and regional disparities leave many without timely support. Digital triage and service-navigation platforms could optimise access.

Current models rely on limited spectra from a small subset of planets, often with degeneracies in composition and cloud structure. High-resolution time-resolved spectroscopy and improved atmospheric retrieval algorithms are needed.

We have detected a handful of mergers, but their cosmic history and diversity remain unclear. Next-generation detectors with wider frequency coverage can map the gravitational-wave background.

Grand unified theories predict proton decay, yet experiments have not observed it. Larger underground detectors and longer observation times are needed.

Microscopic laws are time-symmetric, yet macroscopic phenomena exhibit irreversibility. Deeper understanding of entropy and quantum measurement could help.

Many countries lack timely, granular data on who is poor and why, leading to mistargeted interventions. Mobile and satellite-based poverty-mapping could improve program design.

Intensive agriculture degrades land and biodiversity. Sustainable farming and diets can mitigate impacts.

Communities lack timely information on risks. Low-cost monitoring and alerts can save lives.

Growing passenger and cargo flows strain outdated airports and limited direct flight routes between African cities, increasing travel time and cost. Investment in regional aviation hubs and open-skies agreements could improve connectivity.

Smallholder farmers often rely on traditional knowledge rather than timely forecasts, exposing them to avoidable losses. SMS-based localized forecast services and climate advisory platforms could improve resilience.

Response times are long due to traffic, poor coordination, and scarce vehicles. Tech-enabled ambulance dispatch and motorcycle first responder networks could reduce mortality.
