Mid-November 2013 Sea Surface Temperature (SST) Anomaly Update

Global sea surface temperature anomalies are at about +0.28 deg C for the week centered on November 20th, compared to the base years of 1971-2000.

The sea surface temperature anomalies of the NINO3.4 region in the equatorial Pacific (5S-5N, 170W-120W) are a commonly used metric for the frequency, strength and duration of El Niño and La Niña events.  For the week centered on Wednesday November 20, 2013, they were at about +0.22 deg C.  They are in ENSO-neutral conditions, meaning the tropical Pacific is not experiencing El Niño or La Niña conditions.

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 5 years now, and I’ve searched ocean heat content records for more than 4 years, and I can find no evidence of an anthropogenic greenhouse gas signal.  That is, the data indicates the warming of the global oceans has been caused by Mother Nature, not anthropogenic greenhouse gases.

For a further discussion, see the essay (pdf) titled The Manmade Global Warming Challenge. (It’s 42MB, but it’s free and worth the download time.)

Last year, I 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.

    Hi Bob,

    I just thought about a simple mechanism for heat transfer to the Arctic in the Atlantic basin.
    a) Sun driven Hadley Cell [A high value of 10.7 cm Flux {greater than 120} means lots of energy warming the ocean surface].
    b) Hadley Cell down-welling wind drives surface trade winds/surface ocean currents [occurs +- 20 north/south of Sun’s position].
    c) Surface ocean currents stack up in the Gulf of Mexico creating a warm water bulge.
    d) Bulge helps drive Gulf Stream.
    e) Gulf Stream moves north at 5 mph. It takes 8 days for warm water in the Gulf to reach Nova Scotia, approximately 1000 miles.
    f) In 16 days, the warm Gulf water is now beginning to warm the Northern Atlantic/Arctic Ocean.

    Now these are wind/energy driven surface currents, but that is where most of the heat resides. This same action occurs over in the Pacific at the Equator when the Sun is -20 degrees south. This is the region where the down-welling Hadley winds occur [+-20 degrees north/south of the Sun’s position].

    This could be a partial mechanism for El Nino/ La Nina.

    What do you think,

    Jerry, I’ll have to take a look on Friday. I’ve got family visiting today and tomorrow.

    Dr. Lurtz, it’s a good start towards describing atmospheric and ocean circulation. You’ll need to work in Walker circulation for the east to west trade winds and the equatorial currents.

    I’m skeptical about your steps “c” and “d”, about the bulge in the Gulf helping to drive the water poleward.

    The trade winds push the water from east to west, it encounters land, so it heads poleward.

    nevket240: The way it’s written it sounds as if they discovered the Indian Ocean Dipole last week.
