A Hundred Years of October Cooling

It is amazing how one stumbles into new information. I was looking at Arkansas October temperature history and noticed that it was cooling. I then checked Oklahoma--my home state, and it too was cooling. Before I knew it I had gone through every one of the lower 48 states. Only three states have October warming trends, Florida, Utah and Nevada. I was amazed. Why is this?

Well October is the in between month. Airconditioners which warm our thermometers in the summer are shut down (picture below), but the heating which warms our thermometers in the winter aren't going full blast yet.



So, October may be one of two months that one can actually get a relatively heat source free look at what is happening to the global climate. As you look at the charts below remember one thing, one very important thing--CO2 should work all year round, not just in specific months and not work in other months, like October. Clearly what you will see below is that CO2 has not warmed October in the US.

Let's start with South Dakota because it shows something that the CRU climatologists were aware of--a cooling since 1960. The trees of the world show cooling since 1960 and the climatologists specifically excluded the tree ring data after 1960 to 'hide the decline'. You can clearly see the turn down in temperature in 1960.



In documents/harris-tree/calibrate_nhrecon.pro the lying climatologists write the following in their program.

;
; Calibrates, usually via regression, various NH and quasi-NH records
; against NH or quasi-NH seasonal or annual temperatures.
;
; Specify period over which to compute the regressions (stop in 1960 to avoid
; the decline that affects tree-ring density records)

;
perst=1881.
peren=1960.


Other states show cooling starting as far back as the 1940s with the cooling never stopping in 1975 as is often claimed.



Note that these charts comes from NOAA at this site

I hate to have to admit it but my home state of Oklahoma is also backwards with regards to global warming. Since 1940 Octobers there have also been cooling.







Nebraska:



Iowa:



Global warming hysteriacs certainly won't be mentioning the 60 years of October cooling in Iowa.

And Missouri:



The cooling is probably due to inbreeding up there.

CO2 takes a vacation in October. Even the entire US shows cooling over the past 70 years in October--a month they don't run airconditioners.



Below are the other states. All of them save three Florida, Utah and Nevada show cooling or flat trends. It seems that CO2 doesn't work in October. Here they are

  1. You have made a serious error! Don't you know you are supposed to "Hide The Decline!"

  2. Sorry, I was trying to hide the decline here where there are so few readers no one would notice :-)

  3. Interesting stuff. Any idea what happens for the other 'in between' month?

  4. I looked at August and the warming wasn't as much as I expected. Before this is over I will probably have all the months and states--lots and lots of pictures.

  5. I can't believe I haven't been paying any attention to your blog. I found it a couple months ago. You're a hotbed of information. Keep up the good work, and I have this bookmarked now.

  6. Howdy! Just stumbled across your blog doing research for finals. This 100 year cooling trend is the result a Global Dimming; the accumulation of soot and exhaust in the atmosphere since the onset of the Industrial Revolution. Compare the trend since Congress passed the Clean Air Act in 1970. Incredible progress from that paper.

  7. Over at WUWT some are looking for data that the crew at CRU haven't got their paws on yet, e.g., here for one...

    Maybe you could help them out, if you haven't already.

  8. Nice October surprise. Obviously it's just that the local weather masking the extreme and accelerated warming occurring at those stations. A different sign may be necessary, and an homogenizing AlGoreRhythm adjustment may be needed to correct those discrepancies, which are obviously in error if they conflict with the GCM and USHCN, not to mention the tree-ring proxies other than the other ones used by Briffa et al reconstructions (the ones that didn't show a decline).

  9. Thanks for alerting me to that ytba. That blink chart is fantastic. More hide the decline stuff there.

  10. Here's a scatter plot with the global October temperatures from the NOAA data files: http://globaltemps.files.wordpress.com/2009/12/mean-oct1.png

    You'll see that the bands around 10C and 27C remain constant, showing no temperature increase.

  12. Arizona seems to be going up. could that be due to the population increase and the number of air conditioners running keeps increasing? now they are building houses with 2 of them on each one. hmmmm.

  13. These are excellent facts, so I think that is really good living in those conditions, at least I'd like to live there because in the country I live this is completely different.
