Scientists rush to save historical data locked in melting glaciers

As glaciers worldwide melt, scientists are scrambling to retrieve vital ice cores that hold historical climate records before they are lost forever.

Nicola Jones reports for Yale Environment 360.


In short:

  • Researchers are urgently retrieving ice cores from glaciers worldwide, as warming temperatures melt and corrupt these historical climate records.
  • The Ice Memory Foundation aims to store ice cores in Antarctica to protect them from further damage.
  • The Foundation's goal is to get cores from 20 glaciers around the world in the next 20 years and lock them away in an ice cave in the Antarctic.
  • Many glaciers have already lost valuable data, raising concerns about the future availability of these critical climate archives.

Key quote:

"When you are standing on a glacier that’s literally melting under your feet, you really feel the urgency.”

— Margit Schwikowski, environmental chemist at the Paul Scherrer Institut in Germany and scientific lead for the Ice Memory Foundation.

Why this matters:

Preserving glacial ice cores is important for scientific understanding of historical climate patterns and predicting future environmental changes that can influence global efforts to combat climate change and protect public health.

Scientists fed biochar to cows. Here’s what happened

A new experiment shows biochar survives cow digestion largely intact, potentially turning cattle into a vehicle for spreading this carbon-stabilizing ingredient into the soil.
