今天的人类正面临着全球气温上升、海洋变酸、冰原融化等严重威胁,对此我们能做些什么呢?科学家提出,使用可再生能源(清洁能源)是向着削减二氧化碳排放量迈出的正确一步。但是,仅仅依靠清洁能源不足以阻止气候灾难的发生,而且时间上也太过紧迫。于是,一些科学家提出,可以采取一些更为激进的办法来改造地球,以帮助地球迅速降温,这些办法被统称为“地球工程”。

What are we going to do today when humans are facing the serious threat of global warming, ocean souring and the melting of the ice sheet? Scientists have suggested that the use of renewable energy (clean energy) is the correct way to cut CO2 emissions step. However, reliance on clean energy alone is not enough to stop a climate catastrophe, and it is too time-consuming. As a result, some scientists proposed that some more radical approaches could be taken to transform the earth to help cool the earth rapidly, collectively referred to as “geoengineering.”
