Ice core freezer gets an upgrade

Here's some fun news for summer: plenty of old freezers use refrigerants that are being phased out under the Montreal protocol (including CFCs and HCFCs for their ozone-eating damage, and even HFCs for their greenhouse warming potential) -- including the freezers that scientists use to store ice cores taken from Greenland, the Antarctic and mountain top glaciers.  The NSF storage facility in Denver, which currently uses an HCFC, is now getting an upgrade -- to transcritical CO2. Most fridges still use HFCs... watch this space to see what winds up replacing them. HFOs? Propane? Ammonia? Or CO2? The hunt is on! https://www.nature.com/articles/d41586-024-02287-8
