If evidence for such releases in the water column exists, however, the mechanism and eventual transfer to the atmosphere has not yet been documented clearly.

網頁The hypothesis states that episodic warming of intermediate waters during the last glacial and early deglacial led to dissociation of shallow subsurface methane hydrates and release of methane, contributing to the observed increases of atmosphere methane concentrations, further contributing to climatic warming episodes (10, 11).
網頁New modelling work confirms (Kretschmer et al., 2015) that the Arctic is the region where methane release from clathrates is likely to be most important in the next century, but still estimates methane release to the water column to be negligible compared to anthropogenic releases to the atmosphere. 7 level 1 Zinc_wit · 2 yr. ago · edited 2 yr. ago dr. sanjna john ottawa網頁失控溫室效應（英語： Runaway Greenhouse Effect ）是指行星表面溫度和大氣不透明度之间存在净正回饋，从而增强溫室效應直到行星上的海洋完全蒸發的过程 [1] [2]；比如金星歷史早期就发生过这样的效应。 此現象很容易令人聯想到地球近代因人類活動產生的全球暖化，但其和失控溫室效應在程度上仍有 ... dr. san juan maplewood nj網頁The clathrate gun hypothesis is a proposed explanation for the periods of rapid warming during the Quaternary.
