RSS Global Lower Troposphere Temperature Data for 2016 Confirm Results from UAH.
That is, for 2016, the Temperatures of Earth’s Atmosphere Nearest to Its Surface Were an Insignificant 0.02 Deg C Higher than the Previous El Niño-Related High in 1998.
Vamos, que se confirma que ambos años (1998 y 2016) han tenido "casi" la misma temperatura global.

No , RSS no confirma UAH , comparar con una versión anterior a la que se le ha encontrado un sesgo de enfriamiento (RSS v 3.3 ) es deshonesto , y lo único que si confirma es que hay una diferencia entre RSS y UAH , la cual se tendrá que resolver con estudios cientificios (papers) que diluciden donde esta el error si en RSS o en UAH..

Press Release: 2016 Tropospheric Temperatures.
Date Added:
Thursday, January 5, 2017
A new press release from Dr. Carl Mears
using the Temperature Total Troposphere (TTT) dataset shows that 2016 is the warmest year since the satellite record began in 1979. The previous record, set during the last major El Niño in
1998, was broken by 0.31 degrees Fahrenheit. http://images.remss.com/papers/rsstech/Jan_5_2017_news_release.pdfAtmospheric temperature measured by satellites sets new record in 2016.
Analysis of mid to upper tropospheric temperature by Remote Sensing Systems shows record global warmth in 2016 by a large margin. Using the latest version (Version 4.0) of the “Temperature Total Troposphere” (TTT) dataset, RSS scientists showed that 2016 was 0.31 degrees F warmer than the previous record, set in 1998.
For this work, we used the “Temperature Total Troposphere” (TTT) dataset instead of the more commonly cited “Temperature Lower Troposphere” (TLT) dataset. TTT measures the temperature of a thick atmospheric layer, extending from the surface to about 8 miles (about 13 km) high.
We use TTT because TTT has been updated to version 4.0, while version 4.0 TLT is not yet available. (We use TTT instead of TMT because the latter has not been corrected for the influence of stratospheric cooling.) In the upgrade to version 4.0, we improved the method we use to correct for drifting satellite measurement time, leading to more reliable measurements, particularly since 1998. The new version shows more warming than the older version, particularly since 1998. For more details see: Mears, C. A. and F. J. Wentz (2016). "Sensitivity of Satellite-Derived Tropospheric Temperature Trends to the Diurnal Cycle Adjustment." Journal of Climate 29: 3629-3646.

http://journals.ametsoc.org/doi/10.1175/JCLI-D-15-0744.1 RSS TLT version 3.3 contains a known cooling bias. We are working to eliminate the bias in the new version of TLT. Even with these known cooling biases, 2016 was a record warm year in TLT v3.3. In fact, 2016 was a record warm year in all RSS tropospheric temperature products (TLT v3.3, TMT v3.3, TTT v3.3, TMT v4.0 and TTT v4.0
Aquí lo que se trata es de saber si la temperatura media global ha aumentado y como puede observarse ese ligerísimo incremento de +0,02ºC podemos hablar de la continuidad de la "pausa".
El problema es que ese ligerisimo incremento solo se ve en los satelites , mejor dicho , en solo un producto de satelite , de los 2 en existencia..
RSS , en la versión 4 ,de la capa TTT , que es la mas cercana a la capa TLT , (RSS sige en su version 3.3 para TLT) ..esa diferencia es casi 10 veces mayor..

De esos datos hice este grafico , anual , para apreciar mejor la diferencia entre 1998 y 2016 .
Resulta que la diferencia es de 0,17 celcius , practicamente indistinguible (0,01) y en linea con la tendencia desde 1979 , la cual es 0,18 .
