SEARCH BLOG: GLOBAL WARMING
Additional data is here. Also see right sidebar for information through 2006.
Until the actual data file can be uploaded, this is a .jpg file that shows the 600 monthly record high temperature counts by state. I've banded the warmer periods and shown total records and averages for each period. Click on image for larger view. Feel free to save and print it (it may not print well from your browser).
Because of the anonymous comments regarding lack of usefulness of the data shown above, I did a quick and dirty recut of the columns to group the record counts into "regions"... states that share geography of similar climates. While not a "studied" attempt, it does demonstrate how the data could be used to see where regions are being impacted at different times and look at changes that might cause those patterns such as ocean currents for coastal states, or urbanization in western states, or changes in precipitation/cloud cover in central states. Certainly, looking at a daily record will increase the total points from 600 to around 18,000 which may alter and improve the state patterns somewhat, but I suspect that 600 points is a pretty good sampling for U.S. totals... especially when looking at the time banding of these record events shown in these charts.
What is still not demonstrated is the connection between the frequency of extreme temperatures and the assertion of CO2 based global warming if it is occurring... at least in the U.S.
