I think that this cycle has repeated itself over and over. Methane collects in the sediments at the bottom of the oceans over cooler periods and gets
released again as the world warms.
This may be what has happened in the Bermuda Triangle. One large methane fart under a ship and it drops to the bottom. Or a low aircraft flies
into a methane cloud and loses power.
This cycle could be starting now, as the oceans are heating up, thus increasing global warming which would lead to larger releases in the future as
the temperature warms waters at deeper levels. This could be a runaway train that we have no way of bringing under control.
undercoverchef says... Now... imagine if the most famous of all the mass extinction periods (at the boundary of the cretaceous and
tertiary periods 65 mil years ago) was caused by a massive methane burp that heated up the planet, melted ice caps and caused all sorts of problems!
The end of the cretaceous was a bad time for the dinosaurs and I think a combination of events became too much for them.
The Deccan Traps were formed around the same time as the Chicxulub impact which defined the K-T boundary.
I'm sure the gasses released during the formation of the Deccan Traps were changing the atmosphere of the entire globe over a very long period and
the oceans may have released massive amounts of methane at the same time.
The impact at Chicxulub would have also released carbon into the air as fires burned away plants, bogs and coal that had sequestered it.
The planet has been through so much in the past without the influence of man, but I think we should be taking responsibility for what we can control,
and learning as much as we can about what we have no control over.
I feel we're reaching a point in our evolution that mankind will persist beyond any future changes on Earth, even if it gets as hot as Hell.
Our population may be decimated, but our species will survive in some form.
Also - I had a wobbly Grandmother that was prone to methane releases.
