>The rapid growth in the atmospheric methane burden that began in late 2006 is very different from methane's past observational record
>Recent studies point to strongly increased emissions from wetlands, especially in the tropics
>This increase is comparable in scale and speed to glacial/interglacial terminations when the global climate system suddenly reorganized
Overall, there is a growing research output although much is still unknown. See for example:

Dr Peter Carter has a good run down of the rapid rise in methane emissions:
