Abstract
Ten data sets covering the period 1954-2000 are analyzed to show a 1%/yr in crease in stratospheric water vapor. The trend has persisted for at least 4 5 years, hence is unlikely the result of a single event, but rather indicat ive of long-term climate change. A long-term change in the transport of wat er vapor into the stratosphere is the most probable cause.
