Adjustments are done for many reasons: because there are gaps in the temperature recording stations, because recording stations break, because a new station differs from the old station, because recording stations must be moved, or because the time of day they're read changes, or they shut down because of funding cuts, or the person reading it retires or dies or can't do it as often as they once did, because of urban heat island effects, or because other stations are too close (or toop far) relative to the averge, etc.........
