Some 3,000 scientific robots that are plying the ocean have sent home a puzzling message. These diving instruments suggest that the oceans have not warmed up at all over the past four or five years. That could mean global warming has taken a breather. Or it could mean scientists aren’t quite understanding what their robots are telling them. “There has been a very slight cooling, but not anything really significant,” Willis says. So the buildup of heat on Earth may be on a brief hiatus.
Kommentar von Roger Pielke Sr: The observed absence of heat accumulation (of Joules) in the upper ocean (and in the troposphere) for the last four years means that there has been NO global warming in these climate metrics during this time period. It is unknown whether this is a short term aberration but, regardless, it is clear that the IPCC models have failed to skillfully predict this absence of warming. That should have been the conclusion stated at the end of the NPR story.
