Climate change is reshaping the Earth.
But what would an iceless world look like?
NASA has an idea.
Through radar technology and detailed data collection of 25 million measurements, Bedmap2 provides insight into a changing world.
The original Bedmap was created in 2001.
While Antarctica is 98% covered by ice, underneath is a range of rock mountains and gorges.
The shape of the bed is the most important unknown, and affect how ice can flow.
6.4 million cubic miles of ice could create a 190-foot sea-level rise.
In fact, sea levels arealready risingat a worrying rate.
Researchers are already at work onBedmap3to help further understand our coldest continent in a changing world.
