I read a lot of SciFi and, some 20 years ago, I read a couple of books by David Brin (although I cannot recall if it was Earth or Existence) where he talked about methane hydrates. Global warming had warmed the oceans sufficiently that methane hydrates started to thaw and we were in a desperate battle to refrigerate the poles (and sea bed) to cool the planet although this was not the main subject of the book.

I decided to investigate some of the details in his novel and yes, there are between 1000 and 5000 Gigatonnes of methane stored in a stable hydrate form at the bottom of the oceans. Stable, that is, until the temperature rises.

I told my kids 10 years ago that there wouldn't be a problem unless global methane levels started to rise because that would then signify something really bad was beginning to happen.

I read this today:

Most of my SciFi books I re-read, I never read these particular books again because they started to feel like a (gloomy) documentary.
