difference between these two runs, the sign of the resulting 

 error is not known. 

 3. Areas of land ice in the model include Antarctica, Greenland, 

 islands along the Arctic Ocean, and glaciers in southern 

 Alaska. Had alpine glaciers been included as well, the 

 sea level rise from melting would have been somewhat greater. 



General Comments on the Tables 



1. The hemispheric and global numbers for water and ice were 

 produced with a resolution of hundredths of a mm/day or 

 3.65 mm/yr. The latitudinal numbers used a resolution 



of tenths of mm/day or 36.5 mm/yr. 



2. The hemispheric and global numbers for energy used a 

 resolution of tenths of W/.m 2 except for EMANDC which is 

 know to a hundredth of W.m 2 . The latitudinal numbers 

 used W/m 2 . 



3. ENET is calculated by subtracting large numbers and is 

 therefore less accurate. EMANDC is a diagnostic accumulated 

 directly in the GCM and should be much more accurate. 



(The latter is also true for MANDC). 



4. The numbers are based on a 10 year average (years 26-35) 

 of the control run 882 and doubled CO2 experiment 886. 



5. All numbers are per net area [1 (mm/yr) = 1 (kg/m 2 yr)]. 

 The associated area is all land area. 



6. .0106 (W) added to a square meter of ice will melt 1 (mm) 

 of ice during a year.
