WMO provisional Statement on the status of the global climate 2014 Jeremiah Lengoasa Deputy Secretary-General Lima, 3 December 2014 WMO; Name of Department (ND) Global average temperature anomaly (1850-2014) Global temperature anomaly (Jan-Oct 2014) Global average temperature for Jan-Oct 2014 was 0.57 °C above the 1961-1990 average of 14 °C Anomaly relative to 1961-1990 Comparing Jan-Oct 2014 to earlier years, would rank 2014 as the warmest year on record Precipitation 5 2014 most notable climate anomalies and events Cyclone maximum wind legend (km/h) ▬ 63 – 118 ▬ 119 – 153 ▬ 154 – 177 ▬ 178 – 209 ▬ 210 – 249 ▬ > 249 Heavy rain and floods Cold waves and extremely low temperatures Drought Heat waves and extremely high temperatures 6 Oceans Sea surface temperature anomalies for Jan-Oct 2014 were about 0.45 °C above the 1961-1990 average Jan-Sept 2014 13.1 In 2014, the ocean heat content anomalies estimated for the 700-m (ref. 1955-2006) and 2000m (ref. 1995-2006) layers were approximately equal to, or higher than, in 2013 and higher than any earlier year in the record 7 Arctic sea ice extent On 17 September the Arctic sea ice reached its annual minimum extent, 5.02 million km2, the sixth lowest on record (since 1979), 1.24 million km2 below the 1981-2010 average 8 Greenhouse gas concentrations 2013 CO2 CH4 N2O Amount of GHG in the atmosphere reached a new record high – In April 2014 concentrations of CO2 exceeded 400 ppm on average in the Northern hemisphere 9 Thank you for your attention www.wmo.int Scenarios for the rest of the year 11 Ocean acidification pH surface partial pressure of CO2 (pCO2) 12 El Niño Watch: 2014  WMO El Niño/La Niña Update issued on 1 December 2014  Sea surface temperature anomalies pulled back from El Niño thresholds in July/August, with atmospheric indicators neutral NOAA, 6 November 2014 El Niño affects regional climates, particularly in the tropics/sub-tropical zones, including with health impacts. Economic impact of 1997–1998 El Niño to U.S. economy worthy $25 billion.  Models outlooks still suggest up to a 70% chance of El Niño becoming established in early 2015 13 Scenarios for the rest of the year 14 Cumulative land and ocean carbon uptake simulated for the historical period 1850–2005 IPCC 2013 15
