This is hilariously misleading...
1. the scratches can be interpreted "differently" apparently since your side says something very different than was accepted 12 years ago. In fact, during the summer, an advancing ice age like Greenland was 2 million - 700 years ago will "retreat" a few inches during summer. For the year as a whole, it advanced 10 feet. That doesn't change the fact that the Greenland ice sheet began up north 1-2 million years ago and moved south, only in the 1400s freezing out life on the southern tip... the vikings, well documented history, and a central talking point of the 1970s global COOLING scam.
2. ice cores completely refute "interglacials" since Greenland and AA grew new ice layers straight through the "interglacial"
Fossils and rocks are evidence, and precisely none of that supports "glacials"
The "glacials" are the Co2 FRAUD's attempt to escape the indisputable truth that
Greenland froze while North America thawed
