Global temperature update: no warming for 18 years 4 months
By Christopher Monckton of Brenchley
Since December 1996 there has been no global warming at all (Fig. 1).
This month’s RSS temperature – so far unaffected by the most persistent el Niño conditions of the present rather attenuated cycle – shows a new record length for the ever-Greater Pause: 18 years 4 months – and counting.
This result rather surprises me. I’d expected even a weak el Niño to have more effect that this, but it is always possible that the temperature increase that usually accompanies an el Niño will come through after a lag of four or five months. On the other hand, Roy Spencer, at his always-to-the-point blog (drroyspencer.com), says: “We are probably past the point of reaching a new peak temperature anomaly from the current El Niño, suggesting it was rather weak.” I shall defer to the expert, with pleasure. For if la Niña conditions begin to cool the oceans in time, there could be quite some lengthening of the Pause just in time for the Paris world-government summit in December.
Figure 1. The least-squares linear-regression trend on the RSS satellite monthly global mean surface temperature anomaly dataset shows no global warming for 18 years 4 months since December 1996.
The hiatus period of 18 years 4 months, or 220 months, is the farthest back one can go in the RSS satellite temperature record and still show a sub-zero trend.
Given that the Paris summit is approaching and most “world leaders” are not being told the truth about the Pause, it would be a great help if readers were to do their best to let their national negotiators and politicians know that unexciting reality continues to diverge ever more spectacularly from the bizarre “settled-science” predictions on which Thermageddon was built.
The divergence between the models’ predictions in 1990 (Fig. 2) and 2005 (Fig. 3), on the one hand, and the observed outturn, on the other, also continues to widen, and is now becoming a real embarrassment to the profiteers of doom – or would be, if the mainstream news media were actually to report the data rather than merely repeating the failed predictions of catastrophe.
