Rebecca Priestley’s enthralling collection of writings by Antarctic explorers and scientists starts with Captain James Cook in 1773 on sailing inside the Antarctic Circle, and ends with research biologist Kathryn Smith on the ten-year invasion of predatory king crabs on to the Antarctic sea floor – a warning sign, like so much else in Antarctica, that global warming is a threat to the finely balanced ecosystems that sustain life on Earth.
In between we learn of the numerous important and intriguing scientific discoveries that have been made here over 200 years – from sexually depraved penguins and hermaphrodite sea butterflies to fish full of anti-freeze, melting ice caps, expanding sea ice and a mysterious plethora of meteorites.
A model developed by geologist Nick Golledge has shown that if global warming can be kept below 2°C we may still have a chance of stopping the Antarctic ice sheets from collapsing with almost unimaginable consequences. In Priestley’s words, ‘That’s a goal we can all play a part in achieving.’
