Recordation of global temperatures only commenced with the advent of satellite-based measurement in 1979. Thus, there is only a brief period of accurate global temperature measurement.
The historic temperature record prior to 1979 is (1) not global, (2) inaccurate and (3) completely unreliable.
A substantial portion of temperature records for many locations are unreliable due to the Urban Heat Island effect. Improperly located and maintained stations have also contributed to the unreliability of recorded temperatures.
There are other major fundamental problems with the accuracy of the historic temperature record prior to 1979. Do you really believe that Russian temperature records from, say, 1915-1950 are reliable?
Do you really expect a rational person to believe that people were making accurate daily observations all over Russia during the Revolution or during the Sieges of Stalingrad and Leningrad or in Ukraine during the famine of the 1930s or anywhere in Siberia?
Do you honestly believe that Chinese temperature records from, say, 1913-1980 are reliable? Do you really expect anybody to believe that accurate daily temperatures were recorded in China during the Revolution or \"The Great Leap Forward?\"
Do you seriously believe that Sub-Saharan African temperatures from, say 1850-1975 are accurate? No one can seriously believe that accurate daily temperature recordings were made in Sub-Saharan Africa during any part of the 19th century and most of the 20th.
Do you really believe that oceanic temperatures from, say 1800-1970 are accurate? ( as we know, the oceans cover 70% of the earths surface).
Do you really believe there were accurate daily temperature observations made in the Bering Sea or the Weddell Sea or in the middle of the Pacific at any time before the advent of satellite observations in 1979?
The fact of the matter is that even with 42 years of satellite-based measurement, there has been very little warming (see: http://www.drroyspencer.com/wp-content/uploads/UAH_LT_1979_thru_March_2021_v6.jpg ).
Moreover, to the extent there has been some slight warming, nobody (and I mean NOBODY) knows what caused it. If there has been some virtually unnoticeable warming, it could well be perfectly normal and natural.
There is absolutely no reason whatsoever to create this burdensome and unnecessary reporting. It would be a complete waste of time and resources.
