PRELIMINARY November 2012 Sea Surface Temperature Anomaly Update

Sorry about the delay. I was off having a civil discussion about the natural warming of the global oceans with proponents of anthropogenic global warming.


The November 2012 Reynolds OI.v2 Sea Surface Temperature (SST) data through the NOAA NOMADS website won’t be official until Monday, December 10th. (December already? Oy! Where’d the year go?) Refer to the schedule on the NOAA Optimum Interpolation Sea Surface Temperature Analysis Frequently Asked Questions webpage. The following are the preliminary Global and NINO3.4 SST anomalies for November 2012 that the NOMADS website prepares based on incomplete data for the month. I’ve also included the weekly data through the week centered on November 21, 2012, but I’ve shortened the span of the weekly data, starting it in January 2004, so that the variations can be seen.


The sea surface temperature anomalies of the NINO3.4 region in the eastern equatorial Pacific (5S-5N, 170W-120W) are a commonly used index for the strength, frequency, and duration of El Niño and La Niña events. Based on the preliminary data, November 2012 NINO3.4 SST anomalies are at +0.544 deg C, after cycling back up above the +0.5 deg C threshold of “official” El Niño conditions.

Monthly NINO3.4 SST Anomalies


The preliminary global SST anomalies cooled slightly (-0.014 deg C) in the last month, probably a lagged response to the earlier peaking and drop in the sea surface temperatures along the eastern equatorial Pacific. They’re presently at +0.252 deg C.

Weekly NINO3.4 region (5S-5N, 170W-120W) sea surface temperature anomalies for the week centered on November 21, 2012 have cycled back below the +0.5 deg C threshold of El Niño conditions. They were at +0.410 deg C.

Weekly NINO3.4 SST Anomalies


Weekly Global SST Anomalies made a reasonable rebound after cooling for over a month. They are presently at +0.256 deg C. With things so fluky in the equatorial Pacific, it’s anyone’s guess where they’ll wind up peaking this season.

Why should you be interested? Sea surface temperature records indicate El Niño and La Niña events are responsible for the warming of global sea surface temperature anomalies over the past 30 years, not manmade greenhouse gases. I’ve searched sea surface temperature records for more than 4 years, and I can find no evidence of an anthropogenic greenhouse gas signal. That is, the warming of the global oceans has been caused by Mother Nature, not anthropogenic greenhouse gases.

I’ve recently published my e-book (pdf) about the phenomena called El Niño and La Niña. It’s titled Who Turned on the Heat? with the subtitle The Unsuspected Global Warming Culprit, El Niño Southern Oscillation. It is intended for persons (with or without technical backgrounds) interested in learning about El Niño and La Niña events and in understanding the natural causes of the warming of our global oceans for the past 30 years. Because land surface air temperatures simply exaggerate the natural warming of the global oceans over annual and multidecadal time periods, the vast majority of the warming taking place on land is natural as well. The book is the product of years of research of the satellite-era sea surface temperature data that’s available to the public via the internet. It presents how the data accounts for its warming—and there are no indications the warming was caused by manmade greenhouse gases. None at all.

Who Turned on the Heat?was introduced in the blog post Everything You Ever Wanted to Know about El Niño and La Niña… …Well Just about Everything. The Updated Free Preview includes the Table of Contents; the Introduction; the beginning of Section 1, with the cartoon-like illustrations; the discussion About the Cover; and the Closing. The book was updated recently to correct a few typos.

Please buy a copy. (Credit/Debit Card through PayPal. You do NOT need to open a PayPal account.). It’s only US$8.00.


For those who’d like a more detailed preview of Who Turned on the Heat?, see Parts 1 and 2 of the video series The Natural Warming of the Global Oceans. Part 1, below, appeared in the 24-hour WattsUpWithThat TV (WUWT-TV) special earlier this month.

    Good day from a beautiful avo in Australia.
    same old suspects. Nothing like having an on-side, captive, funding parasite audience, is there?

    Thanks for the heads-up, nevket240. Anthony Watts sent me a link to the Rahmstorf et al (2012) paper and I responded to it here, at least on the temperature side:
