Mid-April 2012 SST Anomaly Update


The weekly global sea surface temperature anomalies are wiggling their way upwards in response to ebbing of the La Niña, and they are now at about 0.12 deg C.

Global SST Anomalies – Short-Term


NINO3.4 Sea Surface Temperature (SST) anomalies (a commonly used El Niño-Southern Oscillation Index) are above the threshold for a La Niña. For the week centered on April 18, 2012, NINO3.4 SST anomalies are approximately -0.39 deg C.

NINO3.4 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. A copy of the introduction, table of contents, and closing can be found here.


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

    Hey Bob,

    It would be most interesting to see a high resolution graph of ocean heat content down to 1500 meters over the past decade versus global SST. 1500 meters is better than 2000 as there are a lot more data points. I actually have no idea exactly what this might tell us, but I do have a strong hunch. The high resolution would be important as we may need to time shift the graphs for my hunch to make sense.

    R. Gates: Link what you like, but make sure to include a link to the source.


  3. Here’s good stuff on ocean warming:


    > Figure 2 below (from Levitus et al.) presents the data in a similar fashion to Figure 1 above, but breaks out the data to show the OHC contribution from the 700 to 2000 meter ocean layer.

    It would be more interesting if deniers would go put their money where their mouths are at Intrade.com

    Hi there, Scott Supak. There are no deniers here that I know of. I’m a luke-warmer. And thanks for the link to the recent SkepticalScience post about Levitus et al (2012). I haven’t read it, won’t bother. I did a post on the NODC’s 0-2000 meter OHC data about 6 months ago.
    There’s no need for me to evaluate it further. Also Willis Eschenbach did a series of posts on the Levitus et al (2012) paper at WattsUpWithThat that you will find educational.

    Last, you appear to have missed my posts that explain how and where natural factors can explain much of the warming of the NODC OHC data for the depths of 0-700meters from 1955 to present. Would you like me to link those posts for you? You might try the search function on this webpage if you’d rather not ask.

    Hi Bob: May I have permission to post your entire letter to “Jimmy Boy” on my http://www.pacificwarmpool.com and my http://www.epwp.com websites? Full links will be provided to this blog or anywhere you want them. I would also like to post it on my http://www.climateclinic.com website, now that I think of it!
