Kiribati, a small island nation in the central Pacific, confronts profound environmental challenges driven by climate change, particularly accelerating sea level rise averaging 8-10 mm annually, king tides, and coastal inundation threatening 80% of its infrastructure. With a population of 119,446 spread across remote atolls, the country maintains good air quality due to lack of heavy industry but struggles with freshwater scarcity, saltwater intrusion into groundwater, and waste management. Government efforts focus on renewable energy transitions, marine protected areas covering over 30% of EEZ, and international advocacy for 1.5°C limits. Historical trends show increased frequency of extreme weather events, underscoring urgent needs for adaptation.
