Note that the film-maker, Martin Durkin, has admitted that this claim about volcanoes is incorrect ( [MSNBC]).

Secondly, while it is true that the oceans are the largest source of CO2, they are also the largest sink (absorber) of CO2 from the atmosphere (see and, and to state one without stating the other is a misleading representation of its role in the environment.

The carbon cycle is the process by which carbon is constantly exchanged between the biosphere, geosphere, hydrosphere and atmosphere of the Earth ( – that is, living creatures, geological formations, bodies of water, and the atmosphere. For roughly the last 10,000 years, until the industrial revolution, the amount of carbon going into the atmosphere has been almost exactly balanced by the amount of carbon coming out of it. Humans have altered one side of this cycle by pumping extra carbon dioxide into the atmosphere without taking any out. Some of this extra carbon dioxide has been absorbed by the oceans, but despite this, atmospheric levels of CO2 have increased by 35% over the past 150 years (see Global Warming Art: 23v5e5). As discussed in the note in Comment 50, page 45, we are able to confirm using two independent methods that the recent increases in CO2 concentrations in the atmosphere are human-induced.

Thus it is irrelevant to say that oceans are the largest source of CO2: the real question is whether the recent 35% increase in CO2 concentrations in the atmosphere is caused by humans (which we know that they are). Thus the narrator is misleading the public as to the real impact of humans on atmospheric carbon dioxide levels.]

Carl Wunsch is professor of Oceanography at MIT. He was also visiting professor of oceanography at Harvard University and University College London; and a Senior Visiting Fellow in Mathematics and Physics at the University of Cambridge. He is the author of four major text books on oceanography.

[Comment 53: Carl Wunsch has been misrepresented by the programme (see Comment 54, page 49 and Comment 94, page 79); and in addition, has stated publicly that he was misinformed by WagTV about the true nature of the programme (see: and Appendix C.20, page 144).]
