同样的，想一想某个工程在短期带来了收益但却将排放危害后人数十年的温室气体。

Similarly, think of an industrial project that brings benefits in the near future but emits greenhouse gases that will harm people decades hence.

此外，已对自负的核能工程技术产生反感的公众，或许也会反对在地下大规模储存一种有潜在窒息风险的气体，而这种大规模储存又为碳捕获和储存装置所必须。

And a public that was turning against hubristic nuclear engineering might also object to the large-scale storage of a potentially asphyxiating gas beneath the ground, which CCS requires.

然而，该报告末尾提出的结论是，除非温室气体的排放是很快能够大幅削减，否则地球工程技术可能成为必要之选。

However, it concluded that unless major cuts to greenhouse gas emissions are made soon, geoengineering technologies may become necessary.
