PRELIMINARY September 2013 Sea Surface Temperature (SST) Update

Someone from NOAA appears to have returned to work to press the “update button” on the NOMADS system for the Reynolds OI.v2 sea surface temperature data. (Thank you!!!) The updated WEEKLY data is available for the week centered on October 2, 2013, but the data for the prior week is missing. As a temporary fix, I’ve used the average of the September 18 and October 2 data for the September 25th values in the weekly plots, until NOAA corrects the problem.

The September 2013 Reynolds OI.v2 Sea Surface Temperature (SST) data through the NOAA NOMADS website would normally have been available on October 7, 2013. Because of the shutdown, and because of the missing weekly data for the week centered on September 25, 2013, I’m going to treat this as a preliminary update until the weekly data is corrected.

I’ve shortened the span of the weekly data. As noted in the recent mid-April 2013 update, I’ve started using January 2001 so that the variations can be seen AND so that you can see how “flat” global sea surface temperature anomalies have been since then.

The base years for anomalies are 1971-2000, which are the standard base years from the NOAA NOMADS website for this dataset.

PRELIMINARY MONTHLY DATA

The preliminary global sea surface temperature anomalies are starting their decline from their seasonally high sea surface temperature anomalies. The global sea surface temperature anomalies are presently at about +0.285 deg C.

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, September 2013 NINO3.4 sea surface temperature anomalies are basically zero (about 0.01 deg C). Also refer to the weekly data that follows.

WEEKLY DATA

Weekly NINO3.4 region (5S-5N, 170W-120W) sea surface temperature anomalies for the week centered on October 2, 2013 are below zero. The weekly NINO3.4 sea surface temperature anomalies were approximately -0.18 deg C.

INTERESTED IN LEARNING MORE ABOUT THE EL NIÑO AND LA NIÑA AND THEIR LONG-TERM EFFECTS ON GLOBAL SEA SURFACE TEMPERATURES?

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 ocean heat content records for more than 3 years, and I can find no evidence of an anthropogenic greenhouse gas signal in either dataset. 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 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.
