Join us at the Polar Museum for a free talk from Geography PhD student Crystal Fu

Searching for vanished ice: What the Arctic’s past tells us about the future climate

Crystal Fu is a PhD student in the Department of Geography at the University of Cambridge studying sea ice sensitivity.

From Crystal:

Arctic sea ice is disappearing rapidly. Since satellite records began in 1979, summer sea ice extent has shrunk by over 2 million square kilometres – an area roughly 10 times the size of the UK. But what was the Arctic like before we could observe it from space? Is it possible to investigate ice that has long since melted away?

In this talk, we will learn about how scientists use mud from the bottom of the Arctic Ocean to uncover the history of sea ice over thousands to millions of years. We will explore how sea ice interacts with the wider climate system, and how Earth’s geological past can help us navigate an uncertain climate future.

Tea & Talks are designed for a non-academic audience and offer the chance to learn something new in a friendly environment. Bring along a notepad (or just an open mind) and join us for a cuppa.
