WMO’s role in greenhouse-gas research and observations

Global-scale observations of atmospheric chemistry and physical property are carried out in order to obtain comprehensive understanding of current state and future projection of the Earth system. There is growing recognition that it contributes to proper addressing of global environmental issues such as global warming. Moreover, there are some phenomena on Earth system change that cannot be revealed by short-term observations. To detect these phenomena, a systematic and long-term observation is necessary. >> More
