Global Temperature for 2022 was 0.84C

The last month of 2022 saw a slight rise in the monthly mean temperature to 0.79C (baseline 1961-1990) resulting in a final yearly average temperature of 0.84C. Arctic air spilled down to lower latitudes bringing extreme cold to the US, Northern Europe and Russia. La Ninja was also weakening (Figure 2)

Finally 2022 ends up as the 4th equal warmest year hinting perhaps of another pause? However  underlying temperature trends are better be measured by using a  10 year icosahedral binning average and this shows no discrepancy.

  1. At risk of betraying my ignorance… where you use ‘temperature’ in this blog, you mean temperature anomaly. Is it a convention amongst climatologists to shorten this as you do, or is there another reason?
    Happy new year btw,

      Hi Adam,

      Yes it is always temperature anomaly. Everyone uses temperature anomaly but slip into using terms
      like “global temperatures have risen by 1.2C” or “We must keep global temperature rise below 1.5C” etc.

      The average actual temperature of the earth changes by more than that each year, partly because it moves closer to the sun due to it’s elliptical orbit and partly because most of the land mass is in the Northern Hemisphere.

      Happy New Year to you too. I just got back from Hong Kong

    Clive Best, you are a very bad influence! Now this retired seismic surveyor has to dive back into Geodesic Surveying, Statistics, Interpolation across many empty bins (analogy in 3D Seismic Survey stacking reflections), reliability of land, airborne, ocean ship, ocean recording buoys, and underwater ocean buoys.
    Personal 1960 experiences with Stevenson Box thermometer reading cast doubts on any reading-series presented in more decimal places than say -4.1 degrees C, due to historical need for a Correction-Card for each thermometer used.

    I am just being lazy 😉

    Yes it is always temperature anomaly relative to a 1961-1990 baseline.

    The temperature anomaly day to day and season to season is far higher

    Hello, I have just downloaded your annual values. They do not match your chart. Is this your old version based on HadSST3 ?

    It looks as though the increase in temperature might correspond to a series of step functions rather than a single function?
