Context
At UN climate meetings in Fiji and Tuvalu, the UN climate chief highlighted growing evidence linking extreme heat with pregnancy complications such as premature birth, stillbirth and low birth weight. The discussions also drew attention to the acute climate vulnerability of Small Island Developing States (SIDS).
Explanation
- Extreme heat can cause heat stress, dehydration and cardiovascular strain, increasing risks during pregnancy.
- Fiji and Tuvalu are Pacific island countries highly exposed to sea-level rise, coral bleaching and extreme temperatures.
- Coral bleaching occurs when heat stress causes corals to expel symbiotic zooxanthellae, making reefs pale and vulnerable.
- Small Island Developing States (SIDS) contribute relatively little to global emissions but face disproportionate climate impacts.
- Climate adaptation finance supports measures that reduce vulnerability to unavoidable climate impacts.
- Just transition seeks an equitable shift towards low-carbon development while protecting vulnerable countries and communities.
