極地冰蓋融化、毀滅性颶風、海平面上升……。面對氣候變化，世界各地都有人積極研究方法應對。本節目將介紹這些人以及他們的創新方法。他們的目標是要減少溫室氣體、維護生物多樣性、提供思考和促進有效行動。每集有四個來自不同地方的項目，這些項目都經實踐，有其寶貴的參考價值。

Melting polar caps, devastating hurricanes, and rising sea levels. The changes ascribed to climate change are disheartening to say the least. Our series Global ideas features people across the world who are pursuing innovative projects to counter global warming.

To reduce greenhouse gases, maintain biodiversity, provide food for thought, and promote effective action – these are the goals of the projects we profile. We present initiatives that are exemplary in character and creative in approach. Each show has four reports. All the projects are “best practice” models, featuring ideas worthy of emulation.
