History
In 1992, three scientists from Environment Canada developed the UV Index, and made Canada the first country in the world to broadcast forecasts of the predicted daily UV levels for the next day. Several other countries followed suit with their own UV indices, among them the United States in 1994. Until recently, the methods of calculating and reporting a UV Index varied from country to country. Today, a worldwide UV Index, standardized by the World Health Organization (WHO), has replaced the inconsistent regional methods. The international UV Index not only specifies a uniform calculation method but also standard colors and graphics for printed media. In the USA, the WHO index replaced the original US index in 2004. In 2005, the United States and Australia launched the UV Alert. While the two countries have different baseline UV intensity requirements before issuing an alert, the goal is to raise awareness of the dangers of overexposure to the sun on days with intense UV radiation.

Famous quotes containing the word history:
“You treat world history as a mathematician does mathematics, in which nothing but laws and formulas exist, no reality, no good and evil, no time, no yesterday, no tomorrow, nothing but an eternal, shallow, mathematical present.”
—Hermann Hesse (1877–1962)
“There is a history in all men’s lives,
Figuring the natures of the times deceased,
The which observed, a man may prophesy,
With a near aim, of the main chance of things
As yet not come to life.”
—William Shakespeare (1564–1616)
“When we of the so-called better classes are scared as men were never scared in history at material ugliness and hardship; when we put off marriage until our house can be artistic, and quake at the thought of having a child without a bank-account and doomed to manual labor, it is time for thinking men to protest against so unmanly and irreligious a state of opinion.”
—William James (1842–1910)
