  •  The persistence of La Niña and a negative PDO... (0+ / 0-)

    I would presume. Since 2003, the Pacific has been somewhat locked in a persistent La Niña/negative PDO phase that has dampened surface temperatures. In the meantime, I surmise, all the extra energy the Earth has been accumulating is being kept below the ocean surface by these natural variations. What needs to happen is another El Niño and a positive Pacific Decadal Oscillation (PDO) to discharge some of the accumulated ocean heat. Now, whether or not climate change is directly altering ENSO/PDO is very unclear and speculative at best. Kevin Trentberth in Balmaseda et al. (2013) has raised some of these ideas. But I will say that the La Niña cycles we've been seeing is basically the equivalent of the Earth being passive-aggressive. Stewing and bottling up the anger (or heat), but not yet blowing up at us. If it lets out the heat with an El Niño, it's going to get progressively worse from here on out, not better.
