Climatologists typically look at climate change using doubledatmospheric CO2 concentrations compared to 1990 levels

Joint research team at Texas A&M derived average scaling factorsfor precipitation and temperature

Under 2xCO2 conditions:

-Precipitation increased by 7% (0.2 inches)

-Temperature increased by 10% (7°F)
