"Variations in the layers of the glacier's ice cores reveal periods of expansion and retreat over 6,000 years. By aligning the history of the glacier with temperature records collected since 1850, we can see how the climate of Europe's alpine region has changed with global warming and how it's likely to change in the future. The ice is a climate archive."
"The drill needs a lot of electricity to run, so we have to bring solar panels and batteries with us, as well as all the drill parts. I often work in temperatures as low as −18 °C, fixing small parts of equipment, so sometimes I can't wear gloves. It takes a certain type of person to do this: you have to be able to focus when you're very cold."
