Global warming will stop until at least 2015 because of natural variations in the climate, scientists have said.
Ñow there\’s actually (at least) three different ways to read this. Firstly, as they themselves describe, things like El Nino and changes in the Gulf Stream change the decadal and annual numbers, but those are simply blips around the underlying trend.
Secondly, that there are more negative feedbacks in the system than anyone currently gives credit to (please note that the IPCC\’s own predictions of warming directly from CO2 emmisions is a 1oC rise for a doubling of atmospheric CO2. The larger rises all come from positive feedbacks).
Thirdly, that some are worried about why there hasn\’t been a year warmer than 1998 yet and are cobbling together an explanation which is still consistent with underlying warming.
One and three are not in fact mutually inconsistent: it\’s really your own level of cynicism about the whole idea which will lead you to prefer one or the other.
