The 2025 small island developing states report of the Lancet Countdown on health and climate change: building resilience in the face of rising heat

Small island developing states (SIDS) are particularly vulnerable to climate change, and people living in SIDS continue to bear the brunt of its manifestations, including sea-level rise, droughts, floods, and extreme weather events. The vulnerability of SIDS stems from their size, remoteness, geographical locations, and small economies. Collectively, SIDS produce less than 1% of the global greenhouse gas emissions, yet climate change presents an existential threat to them. In this report, we shed light on the disproportionate impact of climate change on SIDS and progress towards achieving the goals of the Paris Agreement by presenting the findings of specific indicators at the climate change–health nexus in SIDS.
