Climate variation at Flagstaff, Arizona - 1950 to 2007
Richard Hereford
2007, Open-File Report 2007-1410
Much scientific research demonstrates the existence of recent climate variation, particularly global warming. Climate prediction models forecast that climate will change; it will become warmer, droughts will increase in number and severity, and extreme climate events will recur often—desiccating aridity, extremely wet, unusually warm, or even frigid at times. However,...
