Mid-March 2012 SST Anomaly Update

GLOBAL

After the sudden surge in Global sea surface temperature anomalies during February, the retreat in March seems tame. The changes in weekly global sea surface temperature anomalies slowed over the past couple of weeks, and they are now at about 0.09 deg C.

NINO3.4

NINO3.4 Sea Surface Temperature (SST) anomalies (a commonly used El Niño-Southern Oscillation Index) rose above the threshold for a La Niña last month, but have once again dropped below it. For the week centered on March 14, 2012, NINO3.4 SST anomalies are approximately -0.55 deg C.

NOTE

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

My recently published book is available in pdf and Kindle formats. See If the IPCC was Selling Manmade Global Warming as a Product, Would the FTC Stop their deceptive Ads?
