NASA, the IPCC and probably the other organisations DO NOT acknowledge a "pause in global warming".
'Box 9.2 | Climate Models and the Hiatus in Global Mean Surface Warming of the Past 15 Years
The observed global mean
surface temperature
(GMST) has shown a much smaller increasing linear trend over the past 15 years than
over the past 30 to 60 years (Section 2.4.3, Figure 2.20, Table 2.7; Figure 9.8; Box 9.2 Figure 1a, c). Depending on the observational
data set, the GMST trend over 1998–2012 is estimated to be around one-third to one-half of the trend over 1951–2012 (Section 2.4.3,
Table 2.7; Box 9.2 Figure 1a, c). For example, in HadCRUT4 the trend is 0.04ºC per decade over 1998–2012, compared to 0.11ºC per
decade over 1951–2012. '
https://www.ipcc.ch/pdf/assessment-report/ar5/wg1/WG1AR5_Chapter09_FINAL.pdf'Between 1998 and 2012, climate scientists observed a slowdown in the rate at which the Earth's
surface air temperature
was rising. While the rise in global mean surface air temperature has continued, between 1998 and 2012 the increase was approximately one third of that from 1951 to 2012.
This trend — referred to as a "global warming hiatus" — has sparked a lot of debate and given rise to a reasonable question: Is global warming coming to a halt?'
http://climate.nasa.gov/news/1141/The "hiatus" has also been called the "pause"
'A global warming hiatus,[3] also sometimes referred to as a global warming pause[4] or a global warming slowdown,[5] is a period of relatively little change in globally averaged
surface temperatures
.[6] In the current episode of global warming many such periods are evident in the surface temperature record, along with robust evidence of the long term warming trend.[3]'
https://en.wikipedia.org/wiki/Global_warming_hiatusReally, do we need to do this each and every time?
Yes - it appears we do need to do this each and every time - until you can understand this simple fact:
there is far more to "global warming" than the tiny, tiny bit of it that is surface temperature.
