According to the RSS satellite data, whose value for May 2014 has just been published, the global warming trend in the 17 years 9 [months] since September 1996 is zero (Fig. 1). The 213 months without global warming represent more than half the 425-month satellite data record since January 1979. No one now in high school has lived through global warming.

The hiatus period of 17 years 9 months is the farthest back one can go in the RSS satellite temperature record and still show a zero trend. But the length of the pause in global warming, significant though it now is, is of less importance than the ever-growing discrepancy between the temperature trends predicted by models and the less exciting real-world temperature change that has been observed.

Meanwhile, my understanding is that atmospheric carbon has continued to increase. The models based on carbon don't look very predictive at this point. Via The pause continues – Still no global warming for 17 years 9 months | Watts Up With That?.
