Subsurface heat adding to climate change in melting

The video discusses a study on the Doomsday Glacier, highlighting how the Earth's crust thickness in West Antarctica allows more geothermal heat to reach the glacier compared to the East. This heat, along with climate change, contributes to the glacier's melting. Factors like the type of ground beneath the glacier also affect its temperature, potentially leading to increased ice sliding into the ocean and rising sea levels.

What role does geothermal heat play in the melting of the glacier?

What are the potential consequences of the glacier sliding more easily into the ocean?
