World Solve

Future progress on human development and planetary health depends on solving climate feedback loops accelerating warming. Conventional approaches have proven insufficient. The required intervention must integrate community knowledge, data and appropriate technology while remaining affordable, privacy-preserving and operable with minimal external support. Strong solutions will articulate measurable impact metrics, risk mitigation strategies, and a plan for sustained operation by local actors after the pilot phase.

accelerating loss of the world's forests remains one of the most urgent challenges of our time. Systems currently in place are inadequate for the scale and complexity of the problem. A successful approach must work where resources are scarcest and demonstrate clear, measurable results. It should identify possible harms, respect local agency, and show how the solution can be maintained and expanded by the communities it is meant to serve.

Unregulated over-the-counter antibiotic sales and heavy use in livestock farming are breeding drug-resistant bacteria. Point-of-care rapid diagnostics could reduce unnecessary prescriptions.

Dark energy accounts for roughly 68% of the universe, yet its equation of state and microscopic nature remain complete mysteries. Precise mapping of cosmic expansion over time is crucial for predicting the ultimate fate of space-time.

Extensive glass and concrete urban architecture in Gulf cities amplifies localized heat, driving unsustainable peak air conditioning power demand.

Antibiotics are widely used in livestock farming to prevent disease and promote growth, contributing significantly to antibiotic resistance in humans. Reducing this use without harming farmers' livelihoods remains a persistent unresolved challenge.

Parts of the Greenland ice sheet may have already crossed tipping points where melting continues regardless of future emissions cuts. Understanding and potentially slowing this process remains one of climate science's most urgent unresolved challenges.

Soot particles from fires and diesel engines can settle on snow and ice, absorbing more heat and accelerating melting beyond what temperature alone would cause. Reducing this pollution source at the scale needed to slow ice melt remains unresolved.

Kids today are developing weight-related health problems that used to appear mostly in adults, and this trend is accelerating globally. Solving it needs more than individual willpower, it needs changes to food systems and environments.

Gravity should be pulling everything together over time, yet distant galaxies are accelerating away from each other. This mystery, blamed on dark energy, remains one of the biggest open questions in physics.

A persistent gap exists in realizing practical, scalable solutions for mangrove designs accelerating accretion under rapid sea-level rise. Scientific understanding, engineering readiness and institutional capacity remain insufficient to translate promising concepts into durable impact under real-world constraints of cost, skills and governance.

The absence of robust, context-adapted solutions for adaptive living shorelines keeping pace with accelerating sea-level rise 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.
