Temperature deviation - Kionhensa

...However, from the 1950s to the 1970s, there were more abnormally low temperatures than abnormally high temperatures. If we compare the graph of the change in global mean temperature deviation (the difference from the average value from 1961 to 1990) over the 135 years from 1861 to 1994 with the number of occurrences of abnormally high and low temperatures, we can see that there were more occurrences of abnormally high temperatures up until the 1930s, when the climate was warming. However, from the 1940s onwards, as the climate started to cool, there were more occurrences of abnormally low temperatures. ...
