WMO Statement on the Status of Global Climate (WSSGC)

1. WMO Statement on the Status of Global Climate (WSSGC) WMO OMM By Omar Baddour Observing and Information System Department World Meteorological Organisation • Topics addressed in the WSSGC • Example of 2010 • Key Challenges • Improving WMO CSM

2. WMO Statement on the Status of Global Climate (WSSGC) WMO OMM • 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 Nationallevels, with increasing WMO Members contribution • Scientific coordination by a seconded expert from WMO Members • (rotating from the 6 regions) • Secretariat Coordination (OBS-WIS/ DMA)

3. WMO OMM Topics addressed by the WSSGC

4. 1- Global Surface Temperature Monitoring WMO OMM • Annual Global Surface Temperature Anomaly • w.r.t 1961-1990 global average ( 14°C, 57.2 °F) UK (HadCRUT3) NOAA( NCDC) NASA (GISS) • Annual Global Temperature Ranking 1850 1900 2000 1950

5. 2- Regional Temperatures WMO OMM

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

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

8. 2010

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. 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. 2001-10 clearly warmest decade on record

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. 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. Transition from El Niño to La Niña

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

16. Extreme rainfall in Pakistan leads to record flooding

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

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

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

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. Improving WMO CSM WMO OMM • 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.

24. CCl Task Teams for CSM WMO OMM CCl-Task Team on extreme climate events • 1. Ren Fumen (China) (Lead) • 2. Pattanaik Dushmenda (India) (Co-Lead) • 3. Randall Cerveny (USA) • 4. Blair Trewin (Asutralia) • 5. Boris Sherstyukov (Russia) • 6. Jurq Rapp (Germany) • 7. Diallo Aissatou (Guinea) CCl-Task Team on National Climate Monitoring Products 1. John Kennedy (UK) (Lead) 2. Ladislaus B. Chang'a (Tanzania) (Co-lead) 3. Andrew Watkins (Australia) 4. Xiaolan Wang (Canada) 5. Olga Bulygina (Russia) 6. Mesut Demircan (Turkey) 7. Raj Booneeday (Mauritius) 8. Mohamed Semawi (Jordan) 24

25. Strengthening International collaboration on Climate Monitoring WMO OMM • CCl/CLIVAR/JCOMM Expert Team on Climate Change Detection and IndicesET- 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

26. Congo Workshop, Brazzaville, April 2007 WMO OMM

27. Training Workshop on Statistical Analysis of Climate ExtremesJanuary 17th – 21th of 2010, Guayaquil - Ecuador WMO OMM

28. Climate Watch Systems WMO 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 28

29. 3 Workshops: 2008-2010 WMO OMM 2010 2009 2008 29
