Abstract: Due to the uncertainty of climate science， global warming is quite controversial. However， in order to facilitate policy making， the politicians directly related the issue to CO₂ emission based on some incomplete information from the climate science community and accordingly laid down a range of emission reducing measures， which failed thanks to the environmental rules. Besides these attempts， the scientists tried different kinds of technological fixes， which also failed due to the complexity of the climate system itself. It is argued that global warming is not a problem， but a reality which needs to be confronted with by continuous learning.

Key words: global warming, politicization, technological fix
