Is there any source (especially a Web site) that has the daily weather records for every place on Earth for the past 100 years?
No. However, there are places that have a significant amount of weather data. You can get a good start right here at The Old Farmer’s Almanac Web site, which has a weather history section at http://www.almanac.com/weather/history Find historical weather data by zip code, accessing weather archives for more than 1,300 stations across United States and Canada, going back to 1960.
