Sir David Attenborough research ship prepares for second voyage to Antarctica

The video discusses the concept of tipping points, focusing on the West Antarctic ice sheet, which could cause significant global sea level rise if it melts. A major UK-US research project is studying the Thwaites Glacier to understand climate change impacts. The melting of Antarctic ice has global consequences, potentially affecting sea levels worldwide. Current sea ice concentration data is also briefly mentioned.

What are tipping points in the context of climate change?

What is the significance of the West Antarctic ice sheet in relation to global sea level?

Describe the joint project between the UK and the US regarding the Thwaites Glacier.

How much global sea level rise could result from the melting of the West Antarctic ice sheet?

What implications does the melting of Antarctic ice have for people living outside Antarctica?
