I'm very convinced that the physical process of global warming is continuing, which appears as a statistically significant increase of the global surface and tropospheric temperature anomaly over a time scale of about 20 years and longer and also as trends in other climate variables (e.g., global ocean heat content increase, Arctic and Antarctic ice decrease, mountain glacier decrease on average and others), and I don't see any scientific evidence according to which this trend has been broken, recently.

The study says the global ocean heat content record robustly represents the signature of global warming, and is affected less by weather - related «noise» and climate variability such as El Niño and La Niña events.

What is there is a coherent explanation for the increase in global ocean heat content since the mid-C20th.

«The drop in the global ocean heat storage in the later part of 1998 is associated with cooling of the global ocean after the rapid warming of the ocean during the 1997 — 98 El Niño event (Willis et al. 2004).»

Thus, we suggest that scientists and modelers who seek global warming signals should track how much heat the ocean is storing at any given time, termed global ocean heat content (OHC), as well as sea level rise (SLR).

Me — The Wong reference says — «The drop in the global ocean heat storage in the later part of 1998 is associated with cooling of the global ocean after the rapid warming of the ocean during the 1997 — 98 El Niño event (Willis et al. 2004).»

But if you google «noaa ocean heat and salt content» and compare the first two graphs («0 - 700m global ocean heat content» versus «0 - 2000m global ocean heat content») you will see that the sea SURFACE temperature is much more reflective of what is going on in the atmosphere than the oceans depths.
