World Meteorological Day

Today, 23 March is World Meteorological Day as proclaimed by the World Meteorological Organization. Meteorology is the science of weather and the atmosphere. This year's theme is The ocean, our climate and weather. 

Oceans cover 70% as much of the Earth's surface as does the atmosphere. They are important determinants of heat exchanges from the tropical to polar regions that result in the weather.

What's that got to do with Family History? It's an opportunity to remind that the Canadian Meteorological Service makes historic weather information nationwide available from its observing network, going back to 1840 for Toronto, all without charge. Find out about the weather on the day when you or your parents in Canada were born, or for any other significant occasion in your family history from
