Scientists from around the world with the Intergovernmental Panel on Climate Change (IPCC) tell us that during the past 100 years, the world's surface air temperature increased an average of 0.6 Celsius (1.1 F). This may not sound like very much change, but even one degree can affect the Earth.
Furthermore, agreement is widespread that these changes may profoundly affect atmospheric water vapor concentrations, clouds, precipitation patterns, and runoff and stream flow patterns. Global climate change will affect the water cycle, likely creating perennial droughts in some areas and frequent floods in others.urthermore, because of warmer temperatures, more precipitation is falling as rain rather than snow. One expected effect of climate change will be an increase in precipitation intensity: a larger proportion of rain will fall in a shorter amount of time than it has historically.
