Repository of problems worth solving
World Solve is a public institutional repository for identifying real unresolved problems across science, society, health, governance, economics, and local systems. Each entry is intended to be citable, inspectable, and actionable.
Publicly citable
Every problem has a stable citation code for reference and discussion.
Filtered by relevance
Search by category, geography, status, and keywords.
Builder-oriented
Use the repository to find startup ideas, policy leads, and research agendas.

Forests act as natural carbon sinks, but increasingly severe wildfires are turning some forests from carbon absorbers into carbon emitters faster than they can regrow and recover. Reversing this shift remains an unresolved climate feedback challenge.
