WMO Statement on the Status of Global Climate (WSSGC)
•Part of WCP activity (WCDMP) …Provision of an authoritative annual assessment of the global climate• CCl initiative since 1993• Based on annual climate assessment at Global, Regional and National levels, with increasing WMO Members contribution • Scientific coordination by a seconded expert from WMO Members (rotating from the 6 regions) • Secretariat Coordination (OBS-WIS/ DMA)

Key Challenges
• Ensure collaboration of all Members in providing timely input
• Set standard template procedures and mechanism for Members contribution
• Ensure precise, timely and regular input • Establish RCCs in all regions (remaining RA-III,
IV and V)• What Reference periods for which purpose• Putting the context of climate change
23
Improving WMO CSM
• Provision of guidelines on methodologies and standards for defining extreme weather and climate events that are of major societal impacts and assessing their attribution and return periods (CCl-XV)
• Work on improving WMO Climate System Monitoring including real-time identification of extreme weather, methodologies and datasets for assessing climate trends and variations; and dissemination mechanism for timely informing on extreme weather and climate events (CCl XV)
• EC-LXII requested CCl to develop guidelines with appropriate formats and suitable mechanisms for the Members to follow when submitting their national
contributions to the WMO annual statement on the Global Climate.

Strengthening International collaboration on Climate Monitoring
• CCl/CLIVAR/JCOMM Expert Team on Climate Change Detection and Indices
ET- CCDI– Provide International Coordination for Climate change detection and climate indices
– Develop tools and material including software to calculate indices
– Organize regional Training Workshops
– Peer reviewed publications for contribution to the IPCC assessment reports

Climate Watch SystemsWMO OMM
- To monitor climate anomalies
and related extremes
- To produce and disseminate climate advisories (climate alert bulletins) on significant ongoing or foreseen climate anomalies
- To heighten awareness among relevant users to initiate preparedness measures
- To interact with the users prior, during and after the Alert episode
