Is the Eath's temperature and weather more affected by CO2 or El Nino and La Nina?

Climate Realists think they have the proof that it is the latter not the 'warmist' believers' theory that it is the former:

'It is likely that 2011 will be the coolest year since 1956, or even earlier, says the lead author of a peer-reviewed paper published in 2009:

Our ENSO - temperature paper of 2009 and the aftermath by John McLean

The paper, by John McLean, Professor Chris de Freitas and Professor Bob Carter, showed that the Southern Oscillation Index (SOI), a measure of El Nino-Southern Oscillation (ENSO) conditions, is a very good indicator of average global atmospheric temperatures approximately seven months ahead, except when volcanic eruptions cause short-term cooling.

The lead author, McLean, points to a fall in temperatures that began in October last year, seven months after the abrupt shift to La Nina conditions, and according to last month's data is still continuing.

"The delayed response is important for two reasons." McLean says, "Firstly the high annual average temperature in 2010 was due to the El Nino that ended around March but whose delayed effect on temperature continued until late in the year. Secondly it means that the ENSO conditions can be used to predict with reasonable confidence the average global temperatures up to seven months ahead." '

I know what I believe and oddly I recently discovered that so do more people that I know, they just feel they have to keep it quiet. That is something that I increasingly notice, people feel free to espouse radical leftist views without fear of censure but those of us on the right feel that we have to take care before expressing views that are at variance with the liberal 'consensus'.
