Cosmic Rays : Part 4 : Paleoclimatology and Muons The Field Guide to Particle Physics

When ice forms it traps air molecules with it. Ancient ice, trapped deep in glaciers near the Earth's poles can give us a record of what the atmosphere was like thousands - if not millions - of years ago. But only if we can calibrate the relationship between time and depth. Unlike sunlight, muons from cosmic rays can penetrate deep into this glacial ice, complicating this just a little bit.
