Study Finds ARGO Buoys Show No Evidence Of Missing Heat
By Paul Homewood
Further to recent debate about missing heat disappearing into the oceans, it is worth recalling a study from 2010 by Knox & Douglass.
A recently published estimate of Earth’s global warming trend is 0.63 ± 0.28 W/m2,as calculated from ocean heat content anomaly data spanning 1993–2008. This value is not representative of the recent (2003–2008) warming/cooling
rate because of a “flattening” that occurred around 2001–2002. Using only 2003–2008 data from Argo floats, we find by four different algorithms that the recent trend ranges from –0.010 to –0.160 W/m2 with a typical error bar of ±0.2 W/m2. These results fail to support the existence of a frequently cited large positive computed radiative imbalance.
Of course, we still have only a very short period of ARGO data, so it is much too early to make any projections either way. Nevertheless, this paper confirms there is absolutely no evidence at all that the missing heat has gone into the oceans.
