Nature is the key
Given the widely reported increase in the warming effects of constantly rising greenhouse gas concentrations, the fact that global temperature has not risen over the past 13 years continues to puzzle climate scientists.
The credibility of global warming alarm rests on the fact that global warming has to begin again. If it doesn't happen fairly soon, then the global warming alarmists' bubble will surely burst.
So it is not surprising that there have been many attempts to explain the temperature standstill.
The most recent is a paper by Robert Kaufmann of Boston University and colleagues in the Proceedings of the National Academy of Sciences, which claimed the temperature stasis has been caused by China emitting sunlight-reflecting aerosols from its rapidly increasing number of coal-fired power stations.
One does not have to look far to discover that aerosol data, obtained by satellites, show that global aerosol content - mainly sulphate particles - shows no trend between 2000 and 2006, years covered in the Kaufmann study.
