Worldwide systematic observation of the climate system is a key prerequisite for advancing scientific
knowledge on climate change and advising informed policy making.
The Convention calls on Parties to promote and cooperate in systematic observation of the
climate system, including through support to existing international programmes and networks (Articles 4.1(g) and 5). Implementation is supported through
cooperation with the Global Climate Observing System (GCOS), World Meteorological Organization (WMO) and other agencies. Further background information >>
Parties provide detailed technical reports on systematic observation via their National Communications and in line with the revised UNFCCC reporting
guidelines on global climate change observing systems (decision 11/CP.13).
At SBI 41 (Lima, December 2014), the compilation and synthesis report of the sixth, and
latest, Annex I national communications was presented and included information on research and
systematic opbservation (FCCC/SBI/2014/INF.20/Add.2).
