The Great Global Warming Pause Lengthens Again

Since October 1996 there has been no global warming at all (Fig. 1). This month’s RSS [1] temperature plot pushes up the period without any global warming from 18 years 2 months to 18 years 3 months.

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 3 months since October 1996.

The hiatus period of 18 years 3 months, or 219 months, is the farthest back one can go in the RSS satellite temperature record and still show a sub-zero trend.

As the Pope unwisely prepares to abandon forever the political neutrality that his office enjoins upon him, and to put his signature to a climate-Communist encyclical largely drafted by the radical Prefect of the Pontifical Academy of Sciences, Mgr. Marcelo Sanchez Sorondo, the Almighty continues to display a sense of humor.

We are now less than a year away the Paris world-government conference. Yet the global warming that the IPCC had so confidently but misguidedly predicted 25 years ago has stopped altogether.

Figure 2. Near-term projections of warming at a rate equivalent to 2.8 [1.9, 4.2] K/century, made with “substantial confidence” in IPCC (1990), January 1990 to November 2014 (orange region and red trend line), vs. observed anomalies (dark blue) and trend (bright blue) at less than 1.4 K/century equivalent, taken as the mean of the RSS and UAH satellite monthly mean lower-troposphere temperature anomalies.

A quarter-century after 1990, the global-warming outturn to date – expressed as the least-squares linear-regression trend on the mean of the RSS [1] and UAH [2] monthly global mean surface temperature anomalies – is 0.34 Cº, equivalent to just 1.4 Cº/century, or a little below half of the central estimate in IPCC (1990) and well below even the least estimate (Fig. 2).

The Great Pause is a growing embarrassment to those who had told us with “substantial confidence” that the science was settled and the debate over. Nature had other ideas. Though approaching 70 mutually incompatible and more or less implausible excuses for the Pause are appearing in nervous reviewed journals and among proselytizing scientists, the possibility that the Pause is occurring because the computer models are simply wrong about the sensitivity of temperature to manmade greenhouse gases can no longer be dismissed, and is demonstrated in a major peer-reviewed paper published this month in the Orient’s leading science journal.
