-Det är flera organisationer som samlar in aktuella väderdata. Några använder data insamlat med satelliter. Andra hämtar data från väderstationer. Resultaten är helt olika.

-===== Temperaturens utveckling enligt GISS ===== 
-{{ ::​giss_2016-12-25.jpg?​320|}}Global monthly average surface air temperature since 1979 according to the National Climatic Data Center (NCDC), USA. This time series is calculated using land surface data from the Global Historical Climatology Network (Version 2) and sea surface temperature anomalies from the United Kingdom MOHSST data set and the NCEP Optimum Interpolated SSTs (Version3; note version change on May 2, 2011). The thick line is the simple running 37 month average, nearly corresponding to a running 3 yr average. Base period: 1901-2000. Last month shown: November 2016. Last diagram update: 19 December 2016.

-===== Temperaturens utveckling enligt UHA ===== 
-{{ ::​uah_2016-12-25.jpg?​320|}} Global monthly average lower troposphere temperature since 1979 according to University of Alabama at Huntsville (UAH), USA. This graph uses data obtained by the National Oceanographic and Atmospheric Administration (NOAA) TIROS-N satellite, interpreted by Dr. Roy Spencer and Dr. John Christy, both at Global Hydrology and Climate Center, University of Alabama at Huntsville, USA. The thick line is the simple running 37 month average, nearly corresponding to a running 3 yr average. The cooling and warming periods directly influenced by the 1991 Mt. Pinatubo volcanic eruption and the 1998 El Niño, respectively,​ are clearly visible. Reference period 1981-2010. Last month shown: November 2016. Last diagram update: 6 December 2016.

-Till detta kan läggas att såväl Remss (-0,2), HadCRUT4 (-0,1) som NCDC (-0,15) redovisar att kraftigt temperaturfall senaste månaden, vilket vare sig UAH eller GISS fått med.
