Abstract: This paper introduces the reaction of human intervention in climate change to global warming, which is defined as geoengineering. Then, it proposes that in a broader sense, mankind in the future may be able to manipulate climate based on the operation mechanism of the climate system of the earth. However, the overall impact and side effects of climate control on the climate system of the earth remain uncertain and controversial.

Key words: climate change; geoengineering; climate system; climate control
