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 and satellite recordings from the lower 3-5 km of the atmosphere from satellite in red. The bars show decadal mean temperature based on the thermometer analysis (blue curve). 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.

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 (blue curve). Latest month marked by circles.
