Hurricanes and tornadoes can still shift path or intensity with little warning, leaving communities scrambling to evacuate. More precise, longer-range forecasting could save lives and billions in property damage every year.

Seismologists can identify risky zones but not the exact moment a quake will strike. A few minutes of reliable warning could save thousands of lives in earthquake-prone cities.

Farmers near protected reserves in Morocco suffer repeated crop and livestock losses to wildlife, and existing deterrents are either ineffective or too costly for widespread deployment, fueling retaliatory killings.

The absence of robust, context-adapted solutions for methods for restoring the productivity and resilience of agricultural systems under climate change 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.

Despite recognition of its importance, reliable methods for methods for reducing the transmission of antimicrobial resistance through food and environmental pathways are still lacking. Progress is hindered by incomplete mechanistic knowledge, high capital and operational barriers, and the absence of deployment models suited to the contexts of greatest need.

People displaced by climate impacts from Poland have no dedicated legal migration pathway under current international frameworks, leaving many in prolonged legal limbo.

Despite recognition of its importance, reliable methods for circular economy systems that eliminate leakage of plastics into the environment are still lacking. Progress is hindered by incomplete mechanistic knowledge, high capital and operational barriers, and the absence of deployment models suited to the contexts of greatest need.

Despite recognition of its importance, reliable methods for symbiont-mediated coral heat tolerance enhancement protocols are still lacking. Progress is hindered by incomplete mechanistic knowledge, high capital and operational barriers, and the absence of deployment models suited to the contexts of greatest need.

Achieving technologies for verifying compliance with international environmental agreements at meaningful scale demands simultaneous progress in fundamental research, engineering integration and socio-technical systems that work for low- and middle-income settings. Existing efforts remain fragmented relative to the magnitude of the challenge.

Small businesses in Haiti that adopt solar power still face frequent downtime because battery storage remains too expensive to bridge non-sunny periods, limiting productive use of electricity.

Current approaches to methods for assessing the cumulative impacts of climate change and other stressors on human health either underperform under variable field conditions or generate externalities that undermine long-term sustainability and equity. Closing the gap requires coordinated advances in science, systems design and enabling institutions.

Fast-growing cities in Colombia regularly flood due to undersized or absent stormwater infrastructure, with retrofit costs far exceeding current municipal budgets.

Despite recognition of its importance, reliable methods for solutions for providing safe and dignified housing for climate-displaced populations are still lacking. Progress is hindered by incomplete mechanistic knowledge, high capital and operational barriers, and the absence of deployment models suited to the contexts of greatest need.

The absence of robust, context-adapted solutions for nature-based solutions for flood risk reduction that also support biodiversity and livelihoods 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.

Achieving institutional designs that increase the political feasibility of ambitious climate policies at meaningful scale demands simultaneous progress in fundamental research, engineering integration and socio-technical systems that work for low- and middle-income settings. Existing efforts remain fragmented relative to the magnitude of the challenge.

Current approaches to institutional arrangements that accelerate the diffusion of proven climate solutions either underperform under variable field conditions or generate externalities that undermine long-term sustainability and equity. Closing the gap requires coordinated advances in science, systems design and enabling institutions.

Current approaches to circular economy systems that eliminate leakage of plastics into the environment either underperform under variable field conditions or generate externalities that undermine long-term sustainability and equity. Closing the gap requires coordinated advances in science, systems design and enabling institutions.

Current approaches to interventions that reduce the transmission of vector-borne diseases under changing climate either underperform under variable field conditions or generate externalities that undermine long-term sustainability and equity. Closing the gap requires coordinated advances in science, systems design and enabling institutions.

Achieving transparent and equitable allocation mechanisms for scarce climate finance at meaningful scale demands simultaneous progress in fundamental research, engineering integration and socio-technical systems that work for low- and middle-income settings. Existing efforts remain fragmented relative to the magnitude of the challenge.

Despite recognition of its importance, reliable methods for solutions for managing the growing volumes of construction and demolition waste are still lacking. Progress is hindered by incomplete mechanistic knowledge, high capital and operational barriers, and the absence of deployment models suited to the contexts of greatest need.
