So the report notes that the current «pause» in new global average temperature records since 1998 — a year that saw the second strongest El Nino on record and shattered warming records — does not reflect the long - term trend and may be explained by the oceans absorbing the majority of the extra heat trapped by greenhouse gases as well as the cooling contributions of volcanic eruptions.

Surface temperature is only a small fraction of our climate with most of global warming going into the oceans.

The reason could be linked to rising sea surface temperatures — fueled in part by global warming — as seen in ocean buoy data collected along the U.S. coast.

More than 90 % of global warming heat goes into warming the oceans, while less than 3 % goes into increasing the atmospheric and surface air temperature.

The oceans are heating up: Not only was Earth's temperature record warm in 2014, but so were the global oceans, as sea surface temperatures and the heat of the upper oceans also hit record highs.

«The other carbon dioxide problem», «the evil twin of global warming», or part of a «deadly trio», together with increasing temperatures and loss of oxygen: Many names have been coined to describe the problem of ocean acidification — a change in the ocean chemistry that occurs when carbon dioxide (CO2) from the atmosphere dissolves in seawater.

With the contribution of such record warmth at year's end and with 10 months of the year record warm for their respective months, including the last 8 (January was second warmest for January and April was third warmest), the average global temperature across land and ocean surface areas for 2015 was 0.90 °C (1.62 °F) above the 20th century average of 13.9 °C (57.0 °F), beating the previous record warmth of 2014 by 0.16 °C (0.29 °F).

Ocean temperatures experience interannual variability and over the past 3 decades of global warming have had several short periods of cooling.

The main point is that just as surface temperatures has experienced periods of short term cooling during long term global warming, similarly the ocean shows short term variability during a long term warming trend.

Cooling sea - surface temperatures over the tropical Pacific Ocean — part of a natural warm and cold cycle — may explain why global average temperatures have stabilized in recent years, even as greenhouse gas emissions have been warming the planet.
