8) This change in energy, experienced by the snow was equivalent to moving Earth closer to the Sun. It's a straight-forward inverse-square-law mathematical calculation, which I provided in it's entirety.
9) When all the snow was gone, ice melting proceeded at an accelerated rate, with nothing to buffer it from the onslaught of energy per unit surface area.
10) By 2009, all the ice was 'gone.' Exposed rock exposed to 1100-watts/sq-meter, just 'cooking' up there. This rate of energy absorption per square-meter is identical to what the ice would have experienced, parked at 63-million miles from the Sun.
It's just a different way to think about Earth's energy budget and energy balance.

Please include in your calculations the Delta V of the mass of the Earth to the new perigee. Show your math, 'cause I can't be bothered.
