Abstract:
The analysis of ice cores suggests that temperature rise and growth of the methane concentration of the atmosphere went in the glacial-interglacial cycle in parallel to each other. Similar correlation of changes of temperature and the concentration of greenhouse gases testifies to the presence of a relationship of cause and effect. In this work, on the basis of the three-dimensional mathematical climatic model of the ocean, the methane amount, containig in subbottom methane hydrates in last glacial maximum and under modern climate conditions is estimated. According to mathematical modeling, it is found, that about 270 Gt methane could be released into the ocean/atmosphere system as the result of the instability in the subbottom methane hydrate reservoir in the last glacial episode.
