More global warming oops? 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%26#039;t quite understanding what their robots are telling them.

This is puzzling in part because here on the surface of the Earth, the years since 2003 have been some of the hottest on record. But Josh Willis at NASA%26#039;s Jet Propulsion Laboratory says the oceans are what really matter when it comes to global warming.

In fact, 80 percent to 90 percent of global warming involves heating up ocean waters. They hold much more heat than the atmosphere can. So Willis has been studying the ocean with a fleet of robotic instruments called the Argo system. The buoys can dive 3,000 feet down and measure ocean temperature. Since the system was fully deployed in 2003, it has recorded no warming of the global oceans.

  • Jumping to a conclusion, that this somehow proves AGW is wrong is ludicrous, at best. Dr. Willis isn%26#039;t questioning the theory of AGW. He even hypothesizes that increased cold water from glacier melts could be the cause. Plus, in contrast to surface or atmospheric temperature datasets, only a small fraction of the deep ocean is sampled each year, making it very difficult to detect statistically significant changes.

    You are falling into the trap of assuming that just because there are some unanswered questions about a scientific theory, the theory is therefore wrong or baseless.

    And let%26#039;s not forget the mistake made with some early satellite temperature measurements. The doubters made a big issue about the apparent temperature discrepancy with land-based measurements, until it was found out that orbital drift errors hadn%26#039;t been properly applied.

    Note they are drogued at 40 m and only measure down to 1000 m:

    The mean depth of the ocean is 4 times that, around 4000 meters.
    They only descend to 3000 ft. - to read the deep oceans they would need to get below 20,000 ft.
    It would be very interesting to monitor the western pacific ring of fire and pass over the thousands of sea mounts (active volcanic vents).
    Maybe they could explain this heat anomaly???:
