Jennifer Marohasy dug up a 1952 CSIRO paper, which shows sharp Australian cooling from the hot 1890s to the 1920s. I overlaid the GISS average summer temperature 10 year ending mean for Alice Springs, on the equivalent CSIRO maximum temperature graph for Alice Springs.
The comparison isn’t perfect (average temperature vs. maximum) but it does show how NASA has dramatically cooled Australia’s pre-1930 past, and have in fact turned a 1910-1925 cooling trend into a warming trend.
We know that the raw Alice Springs data was correct, because many other stations showed the same 1910-1925 cooling – which NASA has erased. Once again, NASA is destroying temperature records to suit a political agenda.
This is what NASA did to Alice Springs between GISS V2 and GISS V3
