Whilst were waiting for
Beer Baron to get back with that link lets have a look-see at some ‘adjustments’ made to the climate temperature record:
“…temperatures from the cold 1970’s period were repeatedly “adjusted” years after the event, and progressively got warmer. The most mysterious period is from 1958 to 1978
…Raobcore measurements are balloon measures. They started in 1958, twenty years before satellites. But when satellites began, the two different methods tie together very neatly–telling us that both of them are accurate, reliable tools.
So what do the raobcores tell us about the period before satellites started recording temperatures? They make it clear that temperatures fell quickly from 1960-1970.
If 1958 temperatures were similar to the 1990’s, it rewrites the entire claim of all the unprecedented warming of late…”

Note:
*The above comments were reference mid tropics readings.
*Weather balloon measurements can be fairly accurate depending on which country do them.
*Satellites have issues, especially over snow.
