What’s caused our current interglacial?
Numerous theories exist on what caused our current interglacial. Most explanations greatly oversimplify the cause to a “temperatures increased, so ice melted”, and fail to consider when, how or why the ice melted where it did, and why it didn’t somewhere nearby. For example, during the Oldest Dryas some ice sheets melted vigorously in both the Northern Hemisphere (e.g. western Canada) and in the Southern Hemisphere (Patagonia), while others didn’t and still haven’t (Greenland, Antarctica).
