Climat
Le changement climatique devrait avoir des effets sans précédent sur les populations, les écosystèmes, la sécurité alimentaire, les économies et la paix. Nous comptons sur un climat stable pour prospérer et nous développer. Les changements de température, ainsi que l'élévation du niveau de la mer, ont déjà de profondes répercussions sur les écosystèmes.
