[em]heat [/em]
global insolation watts 1.73E+17
albedo 0.3
global absorbed watts 1.21E+17
insolation variance +- 0.1%
variance in watts +- 1.21E+14
anthropogenic waste heat 1.80E+13

4% global absorbed 4.84E+15*
*Note: cf Chaisson, direct anthropogenic heating equal to 4% of absorbed insolation = 3 degree global temp rise… it can serve as a marker anyway…
