If Planet is Warming Why are CA Max Temperatures Declining?

The global temperature is not soaring, so the anthropogenic global warming scaremongers have been focusing on Max Temperatures at different locations around the planet. Los Angles was recently in the news and debunked HERE and Scotland HERE.

I decided to take a look at Max Temperatures in Nevada County using the historical data from the Nevada City Weather Station.  With the data downloaded and cleaned up, I wrote a simple Python program to do plot the data and do some trend analysis.  This is what I found:

Nevada City

Nevada City Max Temp 1893-2017

Overall there was no trend when examining the total record:

Nevada City Max Temp Trend 1893-2017

However, if I sliced the data from 1931 to 2017 there is a clear negative trend

Nevada City Max Temp trend 1933-2017

Using the same program I downloaded some climate data from some other sites with long temperature histories both end of the Central Valley,  Orland and Bakersfield. The plots are below:





Bakersfield Max temp 1914-2017

Bakerfield Max temp Trend

In the local press and local TV weather reports, we keep hearing about the record-breaking maximum temperatures, but we never hear that over time those maximums are in fact declining. It is always interesting to lift the curtain and see what is going on in the back room. It would appear that within the local weather coverage area from Bakersfield to Orland, the maximum temperatures are in decline.  I wonder why we have not been informed of this overall trend?    Could we be on the cusp of the next grand minimum?

Where has all the heat gone?


Look at all that blue, according to the press the planet is burning up. Look at the global anomaly on the upper right side of the chart.   Look at the blue at the poles. It is summer in the artic and temperatures are below normal.  Where did all the heat go?

Samuel Adams Speech – August 1, 1776

American Independence is a famous speech delivered by Samuel Adams from the steps of the State House in Philadelphia, the meeting place of the Continental Congress. This speech was delivered the day before the familiar parchment copy of the Declaration of Independence was signed by the Continental Congress. The vote for independence was on July 2nd. The decision to use the Declaration written by Thomas Jefferson as the tool to announce the decision publicly was made on July 4th. The document was signed by the members on August 2nd, 1776.

Thirty Years Of Failed Climate Predictions

Tony Heller writes;

On June 23 1988, NASA’s James Hansen testified before Congress and made very specific predictions about global warming. In this video I show how he got them exactly backwards, and how scientists and journalists continue to spread baseless misinformation.

Video is HERE.

OK lefty progressives please tell me where Heller is wrong?

California’s Costly Global Warming Campaign Turns Out To Be Worse Than Useless

For more than a decade, California has won high praise from environmentalists for its stringent greenhouse gas restrictions.

But a new report shows that despite the enormous costs of this effort, the state is doing a worse job at cutting CO2 emissions than the rest of the country, while badly hurting its working families.

Back in 2007, California became the first state to cap CO2 emissions when then-Gov. Arnold Schwarzenegger signed AB32, which mandated the state cut greenhouse gas emissions back to 1990 levels by 2020. Schwarzenegger called it “a bold new era of environmental protection.”

Not to be outdone, Gov. Jerry Brown signed a bill last year requiring the state to cut emissions 40% below 1990 levels by 2030.

So, what happened? From 2007 to 2015, California managed to cut its greenhouse gas emissions by 9%.

But the rest of the country cut them by more than 10%, according to a new report from the Center for Demographics and Policy at Chapman University in Orange, California.

On a per capita basis, 41 states outperformed California on CO2 cuts over those same years.


Who knew, the harder the wackos try the worse it gets!  This is the Progressive’s  Legacy!

The Cause and Effect of Anthropogenic CO2 [Updated & Edited]

Russ Steele

I am reading The Book of Why: The New Science of Cause and Effect by Judea Pearl and Dana Mackenzie. Pearl’s work on cause and effect enables us to know whether one thing causes another, or not. A chapter discusses the origin of heat waves. Pearl looks at the causes of regional heat waves and considers the possibility that climate change is responsible. The target for analysis was the 2003 heat wave in France that killed thousands of people, the highest temperatures recorded was 101.5 F.  My question was this a one-off event caused by anthropogenic climate change or more of a natural phenomenon.

Wikipedia has this insight:

A very significant heat wave occurred in Europe in July 1757. The heat wave may have been the second hottest summer in Europe in the past 500 years, according to reporting after the 2003 European heat wave.[1][2]

July 1757 was the hottest month in the history of Paris with an average temperature of 25 °C (77 °F) (compared to 24.8°C during the 2006 European heat wave), and it reached a high of 37.5 °C (99.5 °F) on July 14th.

1906 – During the 1906 United Kingdom heat wave which began in August and lasted into September broke numerous records. On the 2nd temperatures reached 36 °C (96 °F) which still holds the September record, however, some places beat their local record during September 1911 and September 2016.

1911 – The 1911 United Kingdom heat wave was one of the most severe periods of heat to hit the country with temperatures around 36 °C (97 °F). The heat began in early July and didn’t let up until mid-September where even in September temperatures were still up to 33 °C (92 °F). It took 79 years for temperature higher to be recorded in the United Kingdom during 1990 United Kingdom heat wave.

All these 1700 and 1900 heat waves were before climate change was an issue.

I was looking for some sign of California heat waves in the history files and discovered many Historical Climate Network sites with higher summer temperatures in 1930, spanning summer months with 100-degree temperatures.  It turned out that Nevada City has one of the longest temperature records from 1895 to 2017. Below is a graph of the Max temperatures recorded for each year.

What caught my attention was the slow decline in Max temperatures overtimes, especially over the time when CO2 emissions were increasing.

Nevada City Max Temp

If increased CO2 emissions are causing climate change, the change in Nevada County is a drop in max daily temperatures, not an increase.  However, this is only one data point.  Looking at the summer temperatures of all Historical Climate Network in the US it is possible to see a similar decline in summer temperatures.

Historical Station Summer Temps

Chart from Tony Heller, Real Climate Science

The summer temperature decline starts in the 1940s and continued to 2017, while global CO2 has been increasing.  In looking at the cause and effect, is it possible to say increasing CO2 has reduced the US summer temperatures?  About as easy as saying that rising levels of anthropogenic generated CO2 are responsible for heat waves. And in either case, we do not know, and neither does Judea Pearl.  He would have been much wiser to have avoided the climate change cause question.

Update:   I have added the Bakersfield Max Temperatures from 1914 to 2016 and you can see the decline in max temps over time.


Note all of these temperatures were higher than the 2003 maximum in Paris, all the folks living in Bakersfield should be dead from the heat.
