Historical temperature data comes in different formats. Such as maps, graphs, documented research, and sometimes opinions which at times tend to leave out documented research. There are sites to numeruos to mention on the internet when it comes to looking up historical temperature data etc. I personally reviewed 40-50 years of average temperature data. The conclusion is that avergae high and low temperatures fluctuated very little over this period. There were some wide swings in temperature variations over a short time frame of 3-5 years.
One thing worth mentioning is during a period of warmer than average temperatures, a lot of folks come out of the wood work and talk about how bad Global Warming is and something must been done immediately to remedy the problem. Have one cold snowy winter and the silence from these same people is unanamous. The best way to come to a logical common sense conclusion is by looking at a cross section of government scientist, independent climatologist, and some good old fashion research. If you are looking for research material or are just curious about our past climate, the best approach to find information on this subject is to go to a popular search engine or look to this authors resource box.
Any data is primarily intended for the study of climate variability and weather change. Whenever possible, observations have been adjusted to account for the artificial effects introduced into the climate record by factors such as instrument changes, station relocations, observer practice changes and urbanization. As a result, some values available on this site differ from the official observations.
This site will be a good starting point if you intend to set up your own Weather Almanac or your just looking for more information on Global Climate Change. I hope you enjoy my Weather any kind of weather as much as I do.
