Temperature Increases in California, the United States, and the World

Temperature Increases in California, the United States, and the World

We present temperature rates of increases in degrees Centigrade per Century from Berkeley Earth, for the last 60 years from 1960.  We group them for California, the United States, and the World.  We emphasize Northern cities, states, and countries where the greatest warming has occurred.  There is also great warming in the Middle East.  Svalbard and Jan Mayen are islands East of Northern Greenland, with the highest rate of warming of 5.45 ºC or 9.81 ºF per century.

Most of the rates per century are between 2º C, which is 3.6º F, to 3º C, which is 5.4º F.  Since the interval of increase is almost 60 years, the actual temperature increase since 1960 is found by multiplying the rate per century by 0.6.  To save my fingers, I do not include most of the standard deviations, which are generally around plus/minus 0.2 to 0.3, or about 10%-15%.  If you want the 60 year temperature increase in degrees F, first multiply by 0.6 and then by 1.8, to get 1.08.  This means to use the number shown, but increased by 8%.
