Ha ha. This is ridiculous. Who's been keeping track of weather for 10,000 years? Who's been keeping track of it for 200 years even? Is there a "historical weather book" for the USA for the year 1824, for example, for every major city, for all 365 days of the year? Now imagine those temperature readings, for all over the globe, for every major city, in every country - that would be a LOT of books, just for one year. Where are they stored? Who did the temperature measurements?
