I would consider this statement nonsensical and not properly backed up.

Nonsensical? Sure, possible, if your senses differ much from mine. Not properly backed up? Yep, true, it wasn't. Hopefully it's ok, just a forum, you know.

From this absorption spectrum:

We see that water blocks everything that is non-visible light. ...
_You_ see that. What i see is that "... /cm" part about vertical axis. Thin enough layer of water is transparent to IR. This means IR photons travel within water, once emitted, for some noticeable fraction of centimeter. Then they get absorbed alright, then emitted again to travel few more bits, etc. Please correct me if my school physics are wrong, thank you.
... Further you would have to show that the resonances of methane still exist when dissolved in water, which imho is not at all clear. ...
1st, not all methane is actually dissolved if it's _over_saturation. 2nd, some still exist, i think, otherwise measurement of dissolved methane content by IR laser would probably be impossble? Yet,

Conclusion is rather: It just does not matter how much methane is trapped in water, apart from maybe heat from biological processes. And concerning the atmosphere there are measurements - show us that it is significantly higher than in the past years. I doubt that too.
Seems you doubt everything. Why, i like, it's the right thing. However, it was not my intent to "convince" anybody or "proove" anything. I just answered a particular question describing what i think on a particular subject. It may be very wrong, - i am only a human, and humans tend to make mistakes. The link i've provided in the earlier message is about observations and measurements, but about measurements which i did not make - other humans made them, and they did not give results to me on a silver plate.
I am really sorry for them. How dare they not to handle me all their results... Real-time. Unacceptable!
P.S. Oh, and your "conclusion" is telling. You do not understand even a quarter of all existing mechanisms through which methane changes physical and chemical properties of ocean water and athmosphere - you don't understand them, because nobody does - not you, not me, not very best specialists, because there are lots of complex interactions modern science can't properly model, can't even properly observe and quantify. But you already "conclude" that methane "just does not matter". Sigh, i wonder why exactly i am wasting my, your and others' time typing this - it won't help, i bet. Ok, outta here...
