Observed annual mean temperature since 1880

Annual mean global and hemispheric temperature time series relative to the 1961-1990 mean temperature. Analysis of surface thermometer recordings in blue (mean of GISS and HadCRUT4) and satellite recordings from the lower 3-5 km of the atmosphere from satellite in red (mean of RSS and UAH). The bars show decadal mean temperature based on the thermometer analysis (black curve), with the right-most bar showing the latest, non-complete decade. The mean temperature of the surface and satellite records overlap during 1979-2008; the first 30-year time period covered by both recordings. Latest year marked by circles. Note different temperature scalings.
 
As above, but showing surface temperature (black curve; mean of GISS and HadCRUT4) and the corresponding decadal means. The right-most bar in the panels shows the latest, non-complete decade starting in year 2010.
 
As above, but with the 'hiatus' period 1998-2013 shown in green.
 
As above, but with the green circle showing the mean temperature of the current year (updated to the latest month with data) and with the +/- 2 standard deviation based on the temperature of the remaining months from the latest 20 years shown by the vertical green line.
 
As above, but estimating the warming from preindustrial time until the last full year with data (magenta line segments). Preindustrial temperature is estimated as the average temperature during the first 50 years of data (1880-1929), the latter as the end point of the linear trend for the last 30 years.

Observed and modelled annual mean temperature since 1850

Comparison between observed (black line) and simulated (coloured lines and shadings) annual mean global surface (land + ocean) temperature relative to 1850-1899. The observed temperature time series is extended to the latest month with data (black circle). Gray shading shows the +/-2 standard deviation of the model spread, the coloured shadings show the full model spread, and the dashed, vertical line in 2006 shows the transition from historical (year 1850-2005) to scenario (2006-2100) runs. RCP8.5 is a "business-as-usual" scenario whereas RCP2.6 is constructed to be in line with the two degrees temperature target.

As above, but including the warming since 1850-1899 estimated from the end-point of the linear temperature trend for the last (complete) 30 years with data.
 
Observed temperature from the Hadley Centre. Modelled temperature from the CMIP5 Project. The figure is an updated version of Fig. 1b in Medhaug and Drange (2016), Climate Dynamics, DOI: 10.1007/s00382-015-2811-y [file].

Observed annual mean temperature since 1979

Annual mean global and hemispheric temperature time series relative to the 1979-2008 mean; the first 30-year time period covered by both surface thermometer and satellite recordings. Surface thermometer recordings in blue and satellite recordings from the lower 3-5 km of the atmosphere from satellite in red. The lines show the linear trend for the 1979-2008 period for each data set. Latest year marked by circles.

Observed mean temperature, updated to last month

As above, but with global and hemispheric mean temperature time series for January to latest month of the current year shown with circles (the displayed month gives the latest month with data). For the second half of the year, this comparison gives an idea of the temperature of the current year compared to the previous years.

Observed seasonal mean temperature since 1979

Mean global and hemispheric temperature time series for the four seasons relative to the 1979-2008 mean for the same season. Analysis of surface thermometer recordings in blue and satellite recordings from the lower 3-5 km of the atmosphere from satellite in red. The lines show the linear trend for the 1979-2008 period for each data set. Latest season marked by circles.

Observed monthly mean temperature since 1880

Monthly mean global and hemispheric temperature time series relative to the 1961-1990 mean temperature (upper rows) and 1979-2008 mean (lower rows). Analysis of surface thermometer recordings in blue and satellite recordings from the lower 3-5 km of the atmosphere from satellite in red. The bars in the upper rows show decadal mean temperature based on the thermometer analysis (black curve), with the right-most bar showing the last, non-complete decade. Latest month marked by circles.
