How does climate change affect cross-border cooperation?

• A. It reduces the need for joint planning.
• B. It only affects weather, not cross-border relations.
• C. It increases shared risks requiring coordinated adaptation, financing, and joint planning.
• D. It eliminates the need for data sharing.

Answer: (C)

Climate change creates risks that cross borders and affect multiple countries at once, from extreme floods and droughts to sea‑level rise and disrupted supply chains. Because these threats are shared, governments and organizations must collaborate to understand vulnerabilities, plan together, and pool resources for adaptation. The best answer captures this need for coordinated action across borders—joint planning, financing, and synchronized adaptation efforts—since tackling cross-border risks is only possible through cooperation.

A few contrasts help clarify: reducing the need for joint planning ignores how interdependent climate impacts are; climate change influences governance, economics, and security across borders, not just weather; and data sharing becomes more important, not less, for risk assessment and coordinated responses.
