My friend Josh and I have spent much time working with climate data over several years.
All of our math has been public on my blog sites.
Josh just happened to look at the San Francisco rainfall going back to 1849 and sent me the chart with a long-term average and some rolling averages. (Click on it to increase the size) San Francisco rainfall has no local anomalies to effect it; just millions of square miles of the Pacific Ocean.
If Josh found anything to suggest global warming in the data, he would have called it to our attention.
None of this compares to the 65 years of reliable global data I have presented in many blogs.
But it is a sad reminder that global warming is a religious hysteria of global proportions.
