2. 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) WMO OMM

3. 3 Topics addressed by the WSSGC WMO OMM

6. 6 3- Extreme events Heat Waves Cold Waves Extreme precipitations Flooding and flash floods Drought Wind storms Tropical cyclones WMO OMM

7. 7 Global Precipitations (GPCC, DWD) Sea Ice (NSIDC, USA) Ozone (GAW, WMO) 4- Other climate features Sea Ice September 2007 WMO OMM

8. 2010

9. 9 2010 warmest year on record Mean of three data sets anomaly +0.53°C (2005 +0.52, 1998 +0.51) Ranks 1 in GISS data, 1= in NCDC, 2 in HadCRU

10. 10 Regional temperature variations in 2010 Warmest year on record for Africa (+1.29°C, previous record +0.94 in 2009) Also warmest on record in south/southwest Asia and Greenland/Arctic Canada region Warmest year on record for Canada, India, Turkey Warmest summer on record for Europe and Asia Coldest year since 1996 for northern Europe, since mid-1980s for some countries (UK, Ireland, Norway, Finland)

11. 11 2001-10 clearly warmest decade on record

12. 12 Rapid recent warming in some regions 2001-10 mean 0.7 to 0.9°C warmer than any previous decade in all four regions

13. 13 Rainfall patterns in 2010 Very wet in Indonesia, eastern Australia, central/eastern Europe, Pakistan/western India, Colombia/Venezuela Rather wet in Sahel, south China Dry in Amazon region

14. 14 Transition from El Niño to La Niña

15. 15 Very hot summer in Russia, elsewhere in eastern Europe Russia temperature anomalies, July 2010

16. 16 Extreme rainfall in Pakistan leads to record flooding

17. 17 Winter 2009/10 – cold in northern Europe and the U.S., warm in Canada and Arctic Sources: DWD, Environment Canada, U.S. High Plains Regional Climate Center

18. 18 December 2010 – very cold in northern Europe and Asia, very warm in Canada/Greenland Again exceptional negative phase of Arctic Oscillation Monthly anomalies as high as +14°C in NE Canada, as low as -10°C in Norway and Sweden

19. 19 Low July-September rainfall in the Amazon basin Source: INMET (Brazil)

20. 20 Very wet year in eastern Australia 2 nd wettest year on record for Australia, wettest for eastern states Driest year on record for SW Australia

21. 21 Arctic sea ice 3rd lowest summer minimum, slowest autumn freeze-up

22. 22 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. 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.
