According to Hansen, the land surface has warmed 1.2C since 1880.
This is blatant scientific fraud. As you can see below, he had almost no temperature data in the 1880s for Africa, Greenland, South America, Northern Canada, Siberia, The Arctic, the Antarctic and South Asia. His error bar (green) is much too small to be correct. The few stations in South America and Africa show little or no warming since 1880
To make matters worse, he has corrupted the US temperature data, which makes up more than a third of the available stations for comparison. Note that a number of stations in Africa and Australia have cooled, and that most of his warming is in UHI affected areas. For all we know, the 1880s may have been warmer than the present. How is it that glaciers were rapidly melting in the 1880s, and growing in the 1960s and 1970s? How can he possibly claim that 2011 is 1.2C warmer than the 1880s based on the limited data above? It is complete nonsense to make such a claim.
Before Hansen tampered with the data, the 1880s were nearly as warm in the US as they were in the 1990s. This is critically important – because the lion’s share of high quality global weather stations during the 1880s were located in the US. Hansen’s thermometers reported little warming in the US since 1880s, and the “warming” only appears after the data has been modified. Without the US temperature data tampering (adjustments) the “global” trend since 1880 gets greatly reduced.
The hottest temperature ever recorded in Europe and in Washington DC both occurred in 1881. Hansen’s data has zero legitimacy. He is missing data from at least 0.70 of the land surface during the 19th century, yet reports trends within 0.01 degrees. He would fail any undergraduate science class for reporting a precision two orders of magnitude larger than his accuracy. It is illegitimate science to publish this temperature data without an accurate error bar, and lots of disclaimers describing the severe limitations of accuracy.
It is imperative that he publishes equally available graphs made from unaltered data, even if he honestly believes his bogus adjustments are accurate. And his altered graphs need to be clearly marked. Most people believe that they are seeing temperatures reported by thermometers, and that simply isn’t true.
CIA report below from 1974, showing that snow and ice were increasing during the 1970s. Hansen reports higher temperatures in the 1970s than the 1880s, yet we know that glaciers and polar ice were disappearing in the 1880s.
It would be impossible to have disappearing ice at lower temperatures, and increasing ice at higher temperatures – yet that is exactly what Hansen’s data shows.
