Climate change is having major impacts on Pacific Island states. It is affecting poor communities first and most severely. Rainfall and drought patterns have changed, causing water shortages in several Pacific countries. The increasing frequency and severity of disasters like droughts puts food supplies and livelihoods at risk. Climate change also poses greater health risks as it exacerbates problems like diarrhea and illnesses. Rising sea levels already require some Pacific Islanders to relocate, and climate impacts could increase the potential for conflict as more people become displaced.
