Sentences with phrase «significant increase in ocean heat content»

This was explicitly discussed in Hansen et al, 1997 where they predicted that over the last few decades of the 20th Century, there should have been a significant increase in ocean heat content (OHC).

Not exact matches

We assess the heat content change from both of the long time series (0 to 700 m layer and the 1961 to 2003 period) to be 8.11 ± 0.74 × 1022 J, corresponding to an average warming of 0.1 °C or 0.14 ± 0.04 W m — 2, and conclude that the available heat content estimates from 1961 to 2003 show a significant increasing trend in ocean heat content.

Since the heat capacity of the land surface is so small compared to the ocean, any significant imbalance in the planetary radiation budget (the solar in minus the longwave out) must end up increasing the heat content in the ocean.

If a significant fraction of this heat lost from the ocean went into the atmosphere one might have expected the surface air temperature to have increased faster during this period than during the subsequent period of the 1990s when the ocean heat content gained > 5 X 10 ^ 22 J, but this is not what was observed (see reference Figure 2.7 c in the IPCC TAR Working group I).

The appearance of the first studies on Ocean Heat Content during the 2000's would have been one of the significant factors in the IPCC increasing its level of confidence that AGW was real in its 4th report in 2007.

We assess the heat content change from both of the long time series (0 to 700 m layer and the 1961 to 2003 period) to be 8.11 ± 0.74 × 1022 J, corresponding to an average warming of 0.1 °C or 0.14 ± 0.04 W m — 2, and conclude that the available heat content estimates from 1961 to 2003 show a significant increasing trend in ocean heat content.

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 spatial distribution of the 2006 — 2014 warming indicates that all of the heat content increase during that period is in the southern hemisphere ocean (60 ° S to 20 ° S), with no significant trend in the tropics (20 ° S to 20 ° N) or the northern hemisphere (20 ° N to 60 ° N).

Natural variability in air temperature (the lack of significant warming in the last decade) can be regarded as noise in the monotonic increase due to GHGs, but a one year total (ocean) heat content change can't.
