Can Geoengineering Combat Climate Change?
Some scientists view geoengineering, the concept of manipulating the Earth's climate, as our last line of defense against climate change. But geoengineering is controversial and it's unclear whether it could work.
Correspondent Josh Zepps explores the concept of geoengineering, from cool roofs to imitating volcanic eruptions and placing mirrors in the Earth's upper atmosphere.

應對氣候變化的地球工程？
一些科學家認為地球工程，操縱地球的氣候，為我們抵禦氣候變化的最後一行的概念。但地球工程是有爭議的，目前還不清楚它是否能夠正常工作。

通訊員喬希 Zepps探討地球工程的概念，從涼爽屋頂模仿火山噴發和地球上層大氣中的鏡子。
