There is good agreement on the overall evolution of global temperatures and year-to-year variability. Dataset anomalies are calculated relative to a 1981 to 2010 baseline and offset by 0.69°C, which is the best estimate difference for that period from the 1850-1900 average given in the IPCC sixth assessment report."
The blue numbers are the amount of precipitation in either millimeters (liters per square meter) or inches. The red numbers are the average daily high and low temperatures for each month, and the red bars represent the average daily temperature span for each month. The thin gray line is 0 °C or 32 °F, the point of freezing, for orientation.
The graph includes yearly average global temperature both for data from Met Stations and for combined Land-Ocean temperature, with 10 year moving averages overlayed. Licensing This figure was produced by Leland McInnes using gnuplot and Inkscape and is licensed under the GFDL .

English: Green dots show the 30-year average of the new PAGES 2k reconstruction. The red curve shows the global mean temperature, according HadCRUT4 data from 1850 onwards. In blue is the original hockey stick of Mann, Bradley and Hughes (1999 ) with its uncertainty range (light blue). Graph by Klaus Bitterman.
An early (2018) warming stripes graphic published by their originator, climatologist Ed Hawkins. [1] The progression from blue (cooler) to red (warmer) stripes portrays annual increases of global average temperature since 1850 (left side of graphic) until the date of the graphic (right side).
English: This is a key to a world map showing surface temperature trends between 1950 and 2014. Temperature trends range from -0.5 to +0.5 degrees celsius per decade, and are shown by color gradients: Cooling trend: dark to light blue; No trend: white; Warming trend: light to dark orange
