Judith Curry does some detective work:
“You can’t keep piling up warm water in the western Pacific,” Trenberth says. “At some point, the water will get so high that it just sloshes back.” And when that happens, if scientists are on the right track, the missing heat will reappear and temperatures will spike once again.
JC comment: Well that is an interesting ‘forecast.’ If this is natural internal variability, e.g. the stadium wave (which includes the PDO), then you would expect warming to resume at some point (I’ve argued this might be in the 2030′s). This would make the hiatus 30+ years (similar in length to the pevious hiatus from 1940 to 1975). This is long enough to invalidate the utility of the current climate models for projecting future climate change.
And about the missing heat reappearing, well stay tuned for my next post on ocean heat content.
