What is the Doomsday Glacier? Thanks for asking!

The Thwaites Glacier in West Antarctica is melting rapidly and risks breaking up completely. For nearly a quarter of a century, climate scientists have been observing it closely and have nicknamed it the Doomsday Glacier due to its instability and potential impact on the future of the planet. Thwaites Glacier is more than 1km deep and has a surface area of 74,000 m2, larger than all of England. It’s more than 1,000 miles away from the closest research base, making it remote even for Antarctica.

The speed at which the glacier is melting has increased due to currents of warm water flowing underneath it, wearing away at its base. A study published last month by Gothenburg University researchers showed that the quantity of warm water, measured for the first time using a robotic unmanned submarine, was far higher than previously thought.

How long ago did the glacier start melting? What will happen if the glacier disappears? I bet it isn’t the only glacier in the world that’s causing concern... In under 3 minutes, we answer your questions!
