About

Once considered too cold and sterile to support life, the frozen regions of our planet are now known to harbour some of the least studied yet most vulnerable life on Earth. Microbes thrive in the extremes of the cryosphere, blooming during summer melt seasons, shaping how quickly snow and ice melt, and providing a unique looking glass into ancient Earth biospheres when the world was covered in snow and ice.

Join Dr Chris Williamson to explore the secret life of our glaciers, its uncertain future in a warming world, and what it can reveal about life throughout Earth's history.
