It's going to get cold, really cold over the next few days. In fact, dangerous wind chills are forecasted as a blast of Arctic air approaches Atlantic Canada. The coldest recorded temperature in Nova Scotia was -41.1 degrees Celsius. On January 31st, 1920 in Upper Stewiacke. And that is -40 no matter what scale you might be looking at. And this had me thinking about a number of things, including our lived environment and the critters that live in. And there's a man I know who is the retired curator of zoology, the Nova Scotia Museum of Natural History. Andrew Hebda joins the conversation here today.
