AMS Conceptual Climate Energy Model
Test for System Change

Comparisons based on the difference of one
variable in the system. Each model combination is run
for the chosen number of times. Significance of the
difference is determined by a one-sided, paired t - test.

Reference Boundary Conditions:

Sun's Energy Albedo Atmospheric CO2 Initial Energy Cycles

Modified Boundary Conditions:

Sun's Energy Albedo Atmospheric CO2 Initial Energy Cycles

Number of model runs

Reference Conditions: Mean = --- Standard Deviation = ----
Modified Conditions: Mean = --- Standard Deviation = ----

t-score = ----

Statistically different?   ---
