【藏在热带雨林里的天然降温答案】全球持续升温，气候挑战愈发严峻。CGTN记者杨欣萌跟随世界市长，走进中国唯一的热带雨林城市西双版纳。看似炎热的热带雨林，内部却自带天然调温系统，茂密林木涵养水源、降低气温，形成独特清凉小环境。世界市长们齐聚于此，探讨各自城市的气候挑战。不同气候、不同地理、不同现实，没有通用答案。雨林无法被复制，但它的逻辑值得借鉴：不是对抗高温，而是从源头阻止热量积聚。守护森林、山川、河流，减少化石能源依赖，转向绿色经济。大自然的生存智慧，或许才是城市建设最古老的教科书。Popular culture often portrays tropical rainforests as sweltering, but in reality, they cool themselves naturally. So what better place to discuss how cities in different climates can tackle extreme urban heat than Xishuangbanna, China's only tropical rainforest city?CGTN's Yang Xinmeng joined mayors from around the world there. Their conclusion? There is no one-size-fits-all solution, but rainforests offer an important lesson: they don't fight heat – they prevent it from building up in the first place.Protecting forests, hills and rivers should be a priority for all. The transition away from coal, oil and gas toward greener economies is equally essential. Nature knows how to build cool, livable places.
