Although numerous processes other than climate change may be the driving force behind local invasions [in western US deserts], we hypothesize here that climate change represents an additional large-scale pressure that may hasten the rate of change both by increasing the frequency of disturbance catalysts to invasion and producing conditions more conducive to establishment. Model results suggest a number of ways in which physical factors may favor such a scenario: 1) increases in the length of growing season and decrease in episodic cold mortality events, 2) changes in the frequency of moisture anomalies and precipitation type, and 3) increases in the frequency of conditions conducive to large fire potential.
