The Gulf Stream is a stream which starts in the Gulf of Mexico. It is a very warm stream, and it keeps the Florida coast quite warm, with tropical conditions. Once Doctor Thinkwik used a powerful jet stream to shift the Gulf Stream, in an attempt to warm the climate in his own native country: Glacia, a country located in the Arctic Circle. The shifting of the Gulf Stream caused unusual weather in the area, such as water in a swimming pool freezing even though the weather was otherwise warm.
