More than a third of Ukraine’s scientific institutions have been damaged or destroyed by Russian bombing. Many scientists have either fled the country or are internally displaced, and that Ukraine’s National Academy of Sciences is trying to operate on half its pre-war budget.

Climate change has no borders and Ukraine is making a key contribution to our understanding of the global warming crisis. We hear from the scientists of Ukraine’s National Antarctic Scientific Centre, torn between the frontlines of a prolonged national conflict whilst simultaneously attempting to arm the world with the latest research on a warming climate from the white wilderness of Antarctica.
