Alok Jha talks to Dr Peter Fretwell, award-winning cartographer and leading scientist at the British Antarctic Survey, about Antarctica’s most iconic residents – Emperor penguins – and the threats they’re facing from climate change. 

Peter pioneered the use of satellite imagery to find and monitor polar wildlife – a project that has led to him discovering almost half of the world's Emperor penguin colonies.

He chairs the Scientific Committee on Antarctic Research, Bedmap3 group and ‘Censusing Animal Populations from Space’ (part of the Southern Ocean Observing System) and heads BAS’s ‘Wildlife from Space’ group. He has completed five field seasons in Antarctica.
