Monday's update from NOAA

Summary
•La Niña conditions are developing across the equatorial Pacific.
•Negative sea surface temperature anomalies continue to strengthen
across much of the Pacific Ocean.
•The onset of La Niña conditions is likely during July-August 2010.

Most (surprisingly, not all) models go for the development of a La
Nina, which will persist through the boreal winter. ENSO neutral
conditions are predicted, again, by most models, by next spring.

A short, moderate La Nina? I've said before; if global temperatures do
not fall significantly during this La Nina, the denialists can just
about give up their cause.
