Draw your own conclusion from this map

Today I visited my friend Jim Goodridge, former California State Climatologist and the man with a garage full of data going back to before the Gold Rush.

He’s been quietly toiling away in his retirement on his computer for the last 15 years or so making all sort of data comparisons. He gave me two CD ROMS full of data that I’m just now wading through. One plot which he shared with me today is a 104 year plot map of California showing station trends after painstakingly hand entering data into an Excel spreadsheet and plotting slopes of the data to produce trend dots.

He used every good continuous piece of data he could get his hands on, no adjusted data like the climate miodelers use, only raw from Coopertive Observing Stations, CDF stations, Weather Service Offices’s and Municipal stations.

The results are quite interesting. Here it is:

Squint hard and you can see a pattern emerge.

    Apparently the pattern is so obvious that there are no comments.
