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 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?
