Jo Nova has more from Frank Lansner on what older records, this time from weather balloons, tell us
about recent adjustments to the temperature record. WUWT readers may recall Rewriting the decline
where the graph from National Geographic below raises some questions about temperature graphs
today.

Frank Lansner has done some excellent follow-up on the missing "decline" in temperatures from 1940
to 1975, and things get even more interesting. Recall that the original "hide the decline"
statement comes from the ClimateGate emails and refers to "hiding" the tree ring data that shows a
decline in temperatures after 1960. It's known as the "divergence problem" because tree rings
diverge from the measured temperatures. But Frank shows that the peer reviewed data supports the
original graphs and that measured temperature did decline from 1960 onwards, sharply. But in the
GISS version of that time-period, 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, when a steep 0.3C decline that was initially
recorded in the Northern Hemisphere. Years later that was reduced so far it became a mild warming,
against the detailed corroborating evidence from rabocore data.

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.
