NOAA confirms that La Nina has peaked. Presently, most models are
showing ENSO neutral conditions over the Boreal summer and into Autumn
(slide 27), but things can change very rapidly as ENSO shifts phase
and predictions are pretty speculative. Some models are showing El
Nino conditions developing rapidly and the changes in these NOAA
graphics from last week are the greatest in a 1-week period for a long
time.

Monday update:

"• La Niña has peaked across the equatorial Pacific.*
• Sea surface temperatures (SST) are at least 0.5°C below average
across much of the central and eastern equatorial Pacific Ocean.
• Atmospheric circulation anomalies are consistent with La Niña.
• La Niña is expected to transition to ENSO-neutral conditions during
March-May 2012."

There is a usually a 3-6 month lag between ENSO changes and global
temperatures. As a result, one muight expect global temperatures to
dip further for a couple of months. After that, however, one would
expect them to begin to rise to a peak soon after the next El Nino. If
the pattern of recent El Ninos (2005, 2010)is followed (no reason why
it shouldn't) a new global annual temperature record is very likely to
be set during the next one.

Thought I'd just drop this in en passant.
