Surface-based observations of total cloud amount have been collected from historical records for four continents: North America, Europe, India and Australia. The records extend from 1900 to around 1985. Of the 350 individual station records investigated worldwide, 86% show an increase in total cloud amount or no change. In all four continents there is evidence of an increase in total cloud amount. This upward trend appears to be statistically significant for at least two regions: North America Australia. For North America this finding is corroborated by other recent studies.
