The threshold for a fully fledged La Nina is almost certain to have been triggered, however, this March just gone was warmer that almost every previous March in the satellite record, except those in recent and strong El Ninos (and 1998). That shows the world is anomalously and worryingly warm. The warmth won't go away, though there has been cooling from the extreme peaks of the last El Nino.

Predictions are for ENSO neutral conditions for the foreseeable future, so we should not see the global temperature rise greatly this year.
