Never before published paper on UHI and siting – Goodridge 1987

Plus answers to yesterday’s Fun puzzle: Name these official stations. Given that California Governor Jerry Brown has recently setup a website at the governor’s office basically telling skeptics to “shut up” I thought this would be a good time to publish this. This is a paper that was presented at a climate conference by Jim…

Guest Weblog: CO2 variation by Jim Goodridge, former California State Climatologist

Moderators note: This is reposted from an essay that Jim sent to me. Jim was the State Climatologist for California for many years, and still does consilting work for the Californiua Dept. of Water Resources on rainfall studies. Jim has a command of simplicity in presentation, as you’ll read below. Jim’s presentation lends some insight into why CO2 increases lag temperature…

Trends in the Revised Sunspot Number Dataset

Guest essay by Jim Goodridge, former California State Climatologist Hidden in the sunspot numbers are long-term trends. See the graph below. Orbiting observatories since 1978 show solar irradiance and sunspot number are associated. Sunspots have increased by 1 percent per year since 1700. This suggests recovery from the Little Ice Age of 1660 to 1710. A major increase…

How not to measure temperature (or climate) #97 – California's warming air temperatures are population and site bias related

A couple of days ago, I highlighted a worst of the worst NOAA climate monitoring station in Arizona with the help of a scientist from the University of Washington. My friend Jim Goodridge, former California State Climatologist continues to be busy in his retirement, and sends this along today. He’s been tracking a group of…

Unwarranted Temperature Adjustments and Al Gore's Unwarranted Call for Intellectual Tyranny

Guest essay by Jim Steele, Director emeritus Sierra Nevada Field Campus, San Francisco State University For researchers like myself examining the effect of local microclimates on the ecology of local wildlife, the change in the global average is an absolutely useless measure. Although it is wise to think globally, wildlife only responds to local climate…

Length of day governed by Earth's core processes

From the University of Liverpool , something I found interesting because a few years ago, former State Climatologist Jame Goodridge said he saw correlations between length of day and other atmospheric processes. Research reveals Earth’s core affects length of day Research at the University of Liverpool has found that variations in the length of day…

Q. How did WUWT get started? A. WUWT started out as a broad interest science blog under the umbrella of the Chico Enterprise Record Newspaper “NorCalBlogs” in 2006, where it is still listed. I decided to start blogging there because I had an interest in exploring and doing some experiments about “gee whiz” things. For…

Fun puzzle: Name these official stations

Here’s a fun little puzzle for you, two older station siting photographs from former California State Climatologist, Jim Goodridge, circa the 1980’s. I had Jim find these because I was recently interviewed for a national network newscast, and when I told the story of them, the reporter wanted these photos. Jim found them attached on…

Spencer shows compelling evidence of UHI in CRUTem3 data

McKitrick & Michaels Were Right: More Evidence of Spurious Warming in the IPCC Surface Temperature Dataset Guest post by Roy W. Spencer, Ph. D. The supposed gold standard in surface temperature data is that produced by Univ. of East Anglia, the so-called CRUTem3 dataset. There has always been a lingering suspicion among skeptics that some…
