WMO GHG Bulletin Nov 2013

  1. 1. November 2013
  2. 2. THE RAPID TREND TO PLANETARY CATASTROPHE The 2013 WMO greenhouse gas bulleting shows that there is no let up in the unprecedented rate of heat being added to the climate system - by increasing emissions of long lasting cumulative GHGs to the atmosphere. If this is not stopped it can only lead to total planetary catastrophe. 2012 1975
  3. 3. WMO Greenhouse Gas Bulletin Nov 2013 Executive summary The latest analysis of observations from the WMO Global Atmosphere Watch (GAW) Programme shows that the globally carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) reached new highs in 2012, with CO2 at 393.1 ppm, CH4 at 1819 ppb and N2O at 325. ppb. These values constitute, respectively, 141%, 260% and 120% of pre-industrial (before 1750) levels. The atmospheric increase of CO2 from 2011 to 2012 is higher than the average growth rate over the past 10 years. For N2O the increase from 2011 to 2012 is larger than the average growth rate over the past 10 years. Atmospheric CH4 continued to increase at a rate similar to the one observed over the past 4 years.
  4. 4. Atmospheric GHG concentrations to 2012 WMO GHG Bulletin Nov 2013
  5. 5. Atmospheric GHG concentrations 800,000 year maximum 300 ppm Methane‘s global warming effect is 80 times CO2 over a 20 year period Nitrous oxide’s global warming effect is 289 times CO2 over a 20 year period WMO GHG Budget Nov 2013 2012 level Methane concentration increase 393ppm CO2 Carbon dioxide 800 ppb 1819 ppb Post 2007 renewed sustained atmospheric methane increase Is due to feedback emissions from NH and SH wetland peat. CH4 methane 315 ppb 325 ppb N2O nitrous oxide Sulfa hexafluoride’s global warming effect is 16,000 times CO2 over a 20 year period Sulfa hexafluoride CF6 Methane emissions increase Monthly increase
  6. 6. GHG heating index (WMO 2013)
  7. 7. CO2 heating index to 2012 (NOAA 2013) Total climate system heat content
  8. 8. GHG heating index 2013 Constant rate of heat being added to the climate system The National Oceanic and Atmospheric Administration (NOAA) Annual Greenhouse Gas Index shows that from 1990 to 2012 radiative forcing by long-lived greenhouse gases increased by 32%, with CO2 accounting for about 80% of this increase.
