Marie Cavitte, during a welcome session at the EU Parliament

Welcome, Marie! Could you please introduce yourself to our readers? Hi, my name is Marie Cavitte. I’m a glaciologist and climatologist with a passion for the polar regions. I spent 10 years studying Antarctica. I started off during my Masters, then PhD, looking at the oldest ice on Earth, hunting for THE region of the ice sheet that might contain million-year-old ice. An ice core has been drilled ...[Read More]

The tires smoothly touch the ground, and the warm voice of the flight attendant fills the dry air in the aircraft: “Ladies and Gentlemen, welcome to Ant ...[Read More]

In the age of climate change, glaciers across the Arctic are melting, consequently reducing regional freshwater supplies and contributing to the ongoing rise in global sea levels. But how fast do they melt? And is it possible to predict that? A new study on the Xeitl Sit’ (LeConte) glacier in Alaska aims to answer these questions. The research group from Oregon State University, Harvard University ...[Read More]
