Mid-May 2012 Sea Surface Temperature Anomaly Update


NINO3.4 Sea Surface Temperature (SST) anomalies (a commonly used El Niño-Southern Oscillation Index) are slightly above zero. For the week centered on May 16, 2012, NINO3.4 SST anomalies are approximately +0.035 deg C.

NINO3.4 SST Anomalies – Short-Term


The weekly global sea surface temperature anomalies made another upward surge a couple of weeks ago in response to ebbing La Niña, and last week they made a very slight downturn. They are now at about 0.2 deg C.

Global SST Anomalies – Short-Term


This weekly Reynolds OI.v2 SST dataset begins in 1990. I’ve started the graphs in 2004 to make the weekly variations visible.


The IPCC claims that only the rise in anthropogenic greenhouse gases can explain the warming over the past 30 years. Satellite-based sea surface temperature disagrees with the IPCC’s claims. Most, if not all, of the rise in global sea surface temperature is shown to be the result of a natural process called the El Niño-Southern Oscillation, or ENSO. This is discussed in detail in my first book, If the IPCC was Selling Manmade Global Warming as a Product, Would the FTC Stop their deceptive Ads?, which is available in pdf and Kindle editions. An overview of my book is provided in the above-linked post. Amazon also provides a Kindle preview that runs from the introduction through a good portion of Section 2. That’s about the first 15% of the book. Refer also to the introduction, table of contents, and closing in pdf form here.


OI.v2 SST anomaly data is available through the NOAA NOMADS system:

    Hi Bob,

    Just wanted to make sure you did not miss this Real Climate post where they updated the GISS model projections for Ocean Heat Content changes.

    Significant change in the modelled estimates for the recent periods given they used the incorrect W/m2 absorption estimates (global area versus ocean-only).


    Make sure to check these now updated charts on the older RealClimate posts.


    Much crow to be consumed.

    Thanks, Bill. I’m writing a post right now.
