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.
MY FIRST BOOK
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:
