"Colorado Freezer Reaches Capacity with Ancient Ice Samples Dating Back 4.5 Million Years"

The United States' largest ice repository, located in a minus-40-degree vault in Colorado, is running out of space to store ice samples up to 4.5 million years old. These ice cores are crucial for understanding climate history and the impact of human activities on the environment. However, the outdated freezer is full, and a replacement won't be available for another two years. As a result, the curator of the Ice Core Facility is forced to decide which ice cores to keep and what to do with the surplus. Scientists are racing to collect more ice to fill in the gaps in climate history, but the cost is high. The ice cores provide valuable insights into past climate patterns and help researchers better understand the current changes happening on Earth.
