To start, I went straight to the top. The arctic. The North Pole to be more specific. Turn the a/c as low as you dare, bundle up, and check out the National Atmospheric and Oceanic Administration's Arctic theme page , a collection of cool links. You'll find a web cam watching the pole. Like they say about the sled dog races in this part of the world, the view almost never changes. They do explain why though, and a lot more.
Think about this as you reach for some fresh cubes to cool your drink. We didn't always have the ice maker in the kitchen. Why do you think our grandparents and beyond called the newfangled invention the icebox? I found a site in London that honors not just the London Canal , but also one of its key components… the Ice House. It shows how they actually had to harvest ice in the wintertime, slide it to ships, and ship it to London for the rich folks. They used it for all sorts of things, including, of course, ice cream. So check out the links to the history of our favorite summertime treat.
