So Australia's BOM data and NZ's NIWA data, both «adjusted» out of their cotton picking minds whether needed or not and generally butchered [and thats being polite,] around with until it bears little relationship with reality accounts for at least one fifth and close to nearly one quarter of
the total global land surface temperature data.
Ocean
surface temperatures increase 0,44 deg C,
total global increase 0,55 deg C,
land air increase 0,9 deg C, low troposphere (RSS and UAH) 0,44 deg C. I think you would get much of the same impression of the differences with a different timespan.
