Ocean Questions
These are all the questions I found related to this topic in the 3000+ pages of IPCC AR4 and AR5.
AR6 coming soon!
Another important area of question focused on by the IPCC is the oceans’ temperature because there are many questions as well as important areas lacking data.
To start with, take a look here for an IPCC summary of certainty when it comes to different aspects of the ocean. For example, they speak of it is “virtually certain” the ocean above 700 meters has warmed to the statement it is “likely” warming 3000 and below, going on to state “from 1992 to 2005, while no significant trends in global average temperature were observed between 2000 and 3000 meters”. (AR5 Chapter 3 Executive Summary Page 257)
The IPCC goes on to state it is “also likely that the upper ocean warmed over the first half of 20th century”. They list details about depth, time frames and latitudes here. (AR5 Section 3.2.5 Page 265)
The IPCC notes a study from 2005 to 2010 that shows above 1500 meters the global ocean has warmed. (AR5 Section 3.2.4 Page 263)
The reason they cite a study from 2005 is because they lack data before that time frame, admitting before 2005 they lack ocean temperature data below 700 meters. (AR5 Section 3.2.4 Page 263)
The Southern Hemisphere oceans are much larger therefore able to store a greater amount of heat. However, below of 30°S there are few measuring locations. The Southern Hemisphere oceans is where most of the heat has been absorbed and stored over the last 50 years. (AR5 Section 3.2.2 Page 261)
However, despite the lack of data the IPCC does shows a cooling in the SH, but believe there has been a warming in the upper 1000 meters of the Southern Ocean from 1930s to 1970s, but cooling 1970s to 1990s. (AR5 Section 3.2.2 Page 261)
Last thing to point out in this area is the IPCC believes the ocean’s heat content is slowing less at 0 to 2000 meters than it is at 0 to 700 meters after 2003. (AR5 Section 3.2.4 Page 263)
So Many Ocean Questions
Understanding the ocean’s temperature and its changes are important as this is a factor on ocean currents which have a strong effect on global and regional temperatures.
The IPCC lacks important data on ocean currents but seems to have more data on this than they do with ocean temperatures.
The IPCC admits they lack data on past global ocean currents as well. They note in 1992 a satellite was launched to measure oceans waves with a study done in the early 1990s by the World Ocean Circulation Experiment. (AR5 Section 3.6.1 Page 281)
The Questions Chapter
Over 150 climate questions from AR4/AR5.
Questions and more questions.
This section highlights all the important climate questions described in the UN’s IPCC assessment reports, AR4 and AR5. AR6 is coming soon!
AR4 and AR5 make up the most complete and current climate information out there, a road map for future generations. However, they are not the easiest reads because information on any particular subject is found throughout the 3000+ pages of these reports.
You make think over time there would be less questions as the climate gets figured out, but from AR4 to AR5 the number of question and material increased by several fold.
One reason for this increase in climate questions from AR4 to AR5 is the fact many predictions made in AR4 were missed, and things have been learned.
The IPCC examines most of these in more detail throughout AR5 using AR4 as a base for the science.

What is the IPCC?
UN’s IPCC Assessment Reports 4 and 5 (AR4 2007 and AR5 2014). These UN reports include over 600 authors from 32 different countries assessing 9,200 peer-reviewed studies so they are the all-inclusive on the current state of climate science putting out new reports every seven or so years.
AR5 explains the United Nation’s IPCC was created in 1988 to provide world governments with “clear information on the state of today’s climate science as well as potential impacts, and options for adaptation and migration based on regular assessments”. (AR5 Section 1.2.1 page 123)
