Snot and drifting snow: extreme climate science

"Snotsicle" - clearly unattractive amounts of frozen mucus - are just a few of the challenges facing science in a place as extreme as Antarctica.

Scientists fear a catastrophic collapse of the Thwaites glacier.

West Antarctic ice has a potential sea level rise of more than three meters, enough to flood many large cities around the world and drive hundreds of millions of people out of their homes.

The BBC's main environmental correspondent, Justin Rowlatt, has traveled with a team of scientists who are part of a US $ 50 million (£ 38 million) joint project between the United States and the United Kingdom.

But as he found out, doing science in one of the most extreme environments on earth is not easy.
