Key facts about global temperature
Ø The RSS satellite dataset shows no global warming at all for 225 months from March 1997 to November 2015 – more than half the 443-month RSS record.
Ø There has been no warming even though one-third of all anthropogenic forcings since 1750 have occurred since the Pause began in March 1997.
Ø The entire UAH dataset for the 444 months December 1978 to November 2015 shows global warming at an unalarming rate equivalent to just 1.14 Cº per century.
Ø Since 1950, when a human influence on global temperature first became theoretically possible, the global warming trend has been equivalent to below 1.2 Cº per century.
Ø The global warming trend since 1900 is equivalent to 0.75 Cº per century. This is well within natural variability and may not have much to do with us.
Ø The fastest warming rate lasting 15 years or more since 1950 occurred over the 33 years from 1974 to 2006. It was equivalent to 2.0 Cº per century.
Ø Compare the warming on the Central England temperature dataset in the 40 years 1694-1733, well before the Industrial Revolution, equivalent to 4.33 C°/century.
Ø In 1990, the IPCC’s mid-range prediction of near-term warming was equivalent to 2.8 Cº per century, higher by two-thirds than its current prediction of 1.7 Cº/century.
Ø The warming trend since 1990, when the IPCC wrote its first report, is equivalent to 1 Cº per century. The IPCC had predicted close to thrice as much.
Ø To meet the IPCC’s central prediction of 1 C° warming from 1990-2025, in the next decade a warming of 0.75 C°, equivalent to 7.5 C°/century, would have to occur.
Ø Though the IPCC has cut its near-term warming prediction, it has not cut its high-end business as usual centennial warming prediction of 4.8 Cº warming to 2100.
Ø The IPCC’s predicted 4.8 Cº warming by 2100 is well over twice the greatest rate of warming lasting more than 15 years that has been measured since 1950.
Ø The IPCC’s 4.8 Cº-by-2100 prediction is four times the observed real-world warming trend since we might in theory have begun influencing it in 1950.
Ø The oceans, according to the 3600+ ARGO buoys, are warming at a rate of just 0.02 Cº per decade, equivalent to 0.23 Cº per century, or 1 C° in 430 years.
Ø Recent extreme-weather events cannot be blamed on global warming, because there has not been any global warming to speak of. It is as simple as that.

The Christmas pantomime here in Paris is well int0 its two-week run. The Druids who had hoped that their gibbering incantations might begin to shorten the Pause during the United Necromancers’ pre-solstice prayer-group have been disappointed. Gaia has not heeded them. She continues to show no sign of the “fever” long promised by the Prophet Gore. The robust Pause continues to resist the gathering el Niño. It remains at last month’s record-setting 18 years 9 months (Fig. 1).
Figure 1. The least-squares linear-regression trend on the RSS satellite monthly global mean surface temperature anomaly dataset continues to show no global warming for 18 years 9 months since February 1997, though one-third of all anthropogenic forcings have occurred during the period of the Pause.
The modelers ought to be surprised by the persistence of the Pause. NOAA, with rare honesty, said in its 2008 State of…
