Just an update…as the following graph shows, sea surface temperatures (SSTs) along the equatorial Pacific (“Nino3.4″ region, red lines) have been plunging, and global average SSTs have turned the corner, too. (Click on the image for the full-size, undistorted version. Note the global values have been multiplied by 10 for display purposes.)
Being a believer in natural, internal cycles in the climate system, I’m going to go out on a limb and predict that global-average SSTs will plunge over the next couple of months. Based upon past experience, it will take a month or two for our (UAH) tropospheric temperatures to then follow suit.
