The Nov 2013 annual WMO GHG Bulletin shows the world economy has the world on a fixed course for total planetary catastrophe.

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.

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.
