  So what?
  
   "In less than a decade after that we will have surpassed the remaining "buffer" that would keep warming under the agreed on 2 degree Celsius. Impacts of climate change are already being widely seen and felt. The longer we wait to act the more severe our actions will have to be."  Steve Erickson, aka Chicken Little
  
  Oh really?
  
  "Despite record increases in CO2 concentration, there has been no global warming for almost 13 years (mean of GISS, HadCRUT4, NCDC, RSS, & UAH temperature data: Fig. 5), or, by satellite measurements, for more than 17 years (RSS, 2013: Fig. 6), and no warming distinguishable from the combined measurement, coverage, and bias uncertainties for 18 years (HadCRUT4, 2013: Fig. 7)."
