John Casey is a NASA scientist who shares the minority opinion of Global Cooling instead of Global warming. John Casey has some Youtube videos on the subject of the coming Ice Age. The Ice Age comes every 206 years. John Casey says that, “The Ice Age occurs naturally and nothing can be done by humans to change this cycle.” The Elites knew an Ice Age was coming. Adjustments for Global Warming are nonsense to make us jump through hoops.

The Artic Circle has stopped growing because the Arctic circle and the Northern coasts of the North American Continent and Siberia have merged with the Arctic into one giant ice field. The Northwest passage is gone!
