I understand the facts you state, but I am missing the point you are trying to show me.
The point I'm trying to make is that the glaciers are indeed melting, as they always have, but it's the reduction of snowfall that's causing that melt.
Fresh snow reflects sunlight, no fresh snow allows the atmosphere to continue to dump heat absorbing dust and stuff which contributes to the rise in ice temperature that creates melt.
It's not necessarily a rise in temperature but rather the old ice's inability to reflect the sun's rays which then causes melt.......
That's the best I can do.......
