"Over the past 15 years air temperature at the earth's surface has been flat while greenhouse-gas emissions have continued to soar....The mismatch between rising greenhouse-gas emissions and not-rising temperatures is among the biggest puzzles in climate science today.
The mismatch might mean that-for some unexplained reason-there has been a temporary lag between more carbon dioxide and higher temperatures in 2000-2010. Or it might be that the 1990's, when temperatures were rising fast, was the anomalous period. Or, as an increasing body of research is suggesting, it may be that the climate is responding to higher concentrations of carbon dioxide in ways that had not been properly understood.
This possibility, if true, could have profound significance both for climate science and for environmental and social policy ".
The article "A sensitive matter" in the March 30th 2013 edition of the Economist goes on to explain the uncertainty of the science that cast serious doubt on climate modelling results. For the complete article follow the link below;
