Not sure what that has to do with anything, and I usually don't do links unless maybe if it's just for some backup info for what was already posted (as I did above in another comment), but I peaked.
We've been warmer before, in previous interglacials, and by quite a bit. Scientists are at a complete loss to explain why we are cooler now - yes, COOLER now - than we should be.
Within a millennia of the end of the glacier predating that, 70% of the ice covering Greenland melted. Today, Greenland is still 70% covered with ice.
And of course the the rest of the Arctic was likewise freer of ice, but still despite Steve population declines, the polar bear survived.
There's worse pollution threatening the world than warmer air preventing Long Island from being the terminal moraine of a one mile deep glacier,,,
