Global temperature update:
No warming for 18 years 6 months
By Christopher Monckton of Brenchley
For 222 months, since January 1997, there has been no global warming at all (Fig. 1). This month’s RSS temperature – now beginning to feel the effects of the current el Niño, which will eventually cause temporary warming – shows the Pause sticking at 18 years 6 months, with a global temperature anomaly higher than for two and a half years.
It is becoming ever more likely that the temperature increase that usually accompanies an el Niño will begin to shorten the Pause somewhat, just in time for the Paris climate summit, though a subsequent La Niña would be likely to bring about a resumption and perhaps even a lengthening of the Pause.
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 6 months since January 1997.
The hiatus period of 18 years 6 months is the farthest back one can go in the RSS satellite temperature record and still show a sub-zero trend. Note that the start date is not cherry-picked: it is calculated. And the graph does not mean there is no such thing as global warming. Going back further shows a small warming rate
