{Pralaya - the End of Days} the Great Deluge mentioned in various world mythologies may actually be the memory of the meltdown after the Ice-Age ends. You would remember that pralaya marks the transitions between Yugas and I believe the Milankovitch Cycles fit in quite nicely with the timelines of Yuga cycles as described in our Puranas.

Milankovitch Cycles What are Milankovitch Cycles? Natural global warming, and cooling, is considered to be initiated by Milankovitch cycles. These orbital and axial variations influence the initiation of climate change in long-term natural cycles of 'ice ages' and 'warm periods' known as 'glacial' and 'interglacial' periods. Our current climate forcing shows we are outside of that natural cycle forcing range.
