For a nation that’s unquestionably well known for its cool climate, it’s somewhat remarkable that Canadians invented the UV Index, a measure of the intensity of the sun’s ultraviolet radiation in the sunburn spectrum. As UV increases, the sun’s rays can do more harm to skin, eyes and immune system. In 1992, scientists at Environment Canada developed the index as a health protection tool for Canadians, and 48 stations across the country now forecast it.
I found an interesting Facebook page by J.A. Turner Associates, where you can find lots of trivia about Canada.
