For as much as atmospheric temperatures are rising, the amount of energy being absorbed by the planet is even more striking when one looks into the deep oceans and the change in the global heat content (Figure 4).

These rising atmospheric greenhouse gas concentrations have led to an increase in global average temperatures of ~ 0.2 °C decade — 1, much of which has been absorbed by the oceans, whilst the oceanic uptake of atmospheric CO2 has led to major changes in surface ocean pH (Levitus et al., 2000, 2005; Feely et al., 2008; Hoegh - Guldberg and Bruno, 2010; Mora et al., 2013; Roemmich et al., 2015).

The only time period that remotely resembles the ocean changes happening today, based on geologic records, was 56 million years ago when carbon mysteriously doubled in the atmosphere, global temperatures rose by approximately six degrees and ocean pH dropped sharply, driving up ocean acidity and causing a mass extinction among single - celled ocean organisms.

Thousands of studies conducted by researchers around the world have documented changes in surface, atmospheric, and oceanic temperatures; melting glaciers; diminishing snow cover; shrinking sea ice; rising sea levels; ocean acidification; and increasing atmospheric water vapor.

Meanwhile, as oceans heat up, thermal expansion causes sea levels that are already rising from the melting of land ice (triggered by higher air and sea temperatures) to rise even more.

There are also concerns that oceans, which currently absorb more than 90 percent of the extra heat being trapped by human greenhouse gas emissions, could eventually release some of that back to the surface, speeding up the surface temperature rise.
