In a recent manuscript published in Environmental Science and Technology(1), Zhang warns about a possible Lake Nyos effect from CO2 injection in the ocean. This analogy is not new and has been discussed earlier. Based on material that had been published and available prior to submission of Zhang’s manuscript, the recent IPCC special report on Carbon Dioxide Capture and Storage [2, released December 2005] concluded: “Thus, there is no known mechanism that could produce an unstable volume of water containing 2 million tCO2 at depth shallower than 500 m, and thus no mechanism known by which ocean storage could produce a disaster like that at Lake Nyos”...
