While the Earth seems to be managing the steady increase in atmospheric carbon dioxide relatively well so far (although the effects of this increase may not be felt for many decades to come), there are concerns that passing the 400 parts per million atmospheric carbon dioxide threshold will bring the Earth's atmosphere closer to a tipping point at which global warming accelerates rapidly with dire consequences for mankind and other creatures on Earth.

Warming bottom waters in deeper parts of the ocean, where surface sediment is much colder than freezing and the hydrate stability zone is relatively thick, would not thaw hydrates near the sediment surface, but downward heat diffusion into the sediment column would thin the stability zone from below, causing basal hydrates to decompose, releasing gaseous methane.
