## 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 of the year, extracted 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.
